The headstones are located around the southern 1/3 mark. I was there when my great grandmother was buried though all I remember it that it was a cold and cloudy day. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">I was given this diary by my uncle Tom Stratford, who passed away a few ago. Rather that having the diary sit somewhere in drawer I thought I was share it as I read through it. I will also add pictures as they are discovered. Dates are a bit of an issue as there are many entries that only have the month and day and some with no date. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">I read through the diary and it is not a daily record. Rather, my great grandfather used to the diary over several years to record different events. I will use this space to put events in chronological order so this is a working document and I will annotate accordingly. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><b>January 1, [1924]</b></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjOWwTI-99Lj89AxbpgpY-oTI_kZ2N5MBNQsWXtna36ABgkLydEtWAE1st1uDUXivi8FUGI5C5I7he0QO_ks1YCR8G6BtFxnKzGPFPifjoDAaGiSO1CxKAZme9xNfc74ur2tmJhjUy41iLs6AfsT7fW5LR0ETmd3hf95B-Yq8Gfik33F-sZLNbkVP2U" style="margin-left: 1em; margin-right: 1em;"><img data-original-height="3834" data-original-width="2454" height="400" src="https://blogger.googleusercontent.com/img/a/AVvXsEjOWwTI-99Lj89AxbpgpY-oTI_kZ2N5MBNQsWXtna36ABgkLydEtWAE1st1uDUXivi8FUGI5C5I7he0QO_ks1YCR8G6BtFxnKzGPFPifjoDAaGiSO1CxKAZme9xNfc74ur2tmJhjUy41iLs6AfsT7fW5LR0ETmd3hf95B-Yq8Gfik33F-sZLNbkVP2U=w257-h400" width="257" /></a><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhotWnKuxd-2RVKoKpc4o1tdjsJrFaWgLTED467RwdNEZWfSvd9JCwW_ITifyBVBTYl3W9detKMpm1HnlWPPWmWQo0_o2RCTUZxnNDHJKLHPjyUHO2lyJGGZ47DyGnxZdL-kTGRry_R-dI-1QkJ0JAm1CtH35ivfpHemSat6t2vpqqNpHKatQAl9sei/s4032/stratford_thomas_diary2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4032" data-original-width="3024" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhotWnKuxd-2RVKoKpc4o1tdjsJrFaWgLTED467RwdNEZWfSvd9JCwW_ITifyBVBTYl3W9detKMpm1HnlWPPWmWQo0_o2RCTUZxnNDHJKLHPjyUHO2lyJGGZ47DyGnxZdL-kTGRry_R-dI-1QkJ0JAm1CtH35ivfpHemSat6t2vpqqNpHKatQAl9sei/w300-h400/stratford_thomas_diary2.jpg" width="300" /></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiSdKfpAUtn-Rbes49fdp1buDS39FBmoKSI8dAk7Pd-e5GgtnXXwPpjfU3HB2iBbnLHp6Dc9GZ-Rz-8BT7S0Y4bwKTzhg8oKCIj_0N61QTz7xmIyi4amJHl79fd5HERqTMjGdJV3oLmuH1ugjDLlk4XGldx6vPGVyJhPpo49hpekk1Ml1WJEvygB76e/s4032/stratford_thomas_diary19140103.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="4032" data-original-width="3024" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiSdKfpAUtn-Rbes49fdp1buDS39FBmoKSI8dAk7Pd-e5GgtnXXwPpjfU3HB2iBbnLHp6Dc9GZ-Rz-8BT7S0Y4bwKTzhg8oKCIj_0N61QTz7xmIyi4amJHl79fd5HERqTMjGdJV3oLmuH1ugjDLlk4XGldx6vPGVyJhPpo49hpekk1Ml1WJEvygB76e/w300-h400/stratford_thomas_diary19140103.jpg" width="300" /></a><br /><br /></div><br /><div class="separator" style="clear: both; text-align: left;"><b><br /></b></div><div class="separator" style="clear: both; text-align: left;"><b>Entries in chronological order</b></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">June 14, 1924 </div><div class="separator" style="clear: both; text-align: left;">"Rec'd check for 30.00 interest on Gen.

Unfortunately, none of the specimens had labels so many were tossed. Around 2011, we inherited hundreds of insects from Mike, a friend of the university that took care of the university and also a school teacher. These insects were also without any collection information and many were thrown out. Heart breaking but what is the value of a specimen without any data? </p><p>In the meantime, we were collecting arthropods as part of study of grassland restoration (see https://onlinelibrary.wiley.com/doi/full/10.1111/rec.12202), then as a study of the effects of grassland management on diversity in fifteen grasslands (accepted in Ecosphere). Those samples were sorted to order. Many were photographed and data were entered into Biota. I'm still trying to find the images - my worry is that the file was created by someone that graduated and no longer accessible. Lesson learned. </p><p>More recently, I became interested in the effects of prescribed burning on pollinators and food webs more largely. In the last two years, I must have collected, I'm estimating, about 10,000 insects and we have sorted about 4200 insects so far. There are another 20,000 insects that are still in jars, envelopes, etc. so be sorted. Yep, I have quite the work load ahead of me. I'm sending many samples off to be analyzed for the food web study and we are focusing on omnivores - because their trophic position can tell us about the productivity of a site. </p><p>I wanted to run some summary statistics to both create a benchmark for tracking progress of the collection and quality control. Simply by producing tables, I can catch spelling mistakes and other typos. </p><p>We had 529 collection events entered. That's a pitfall, sweep, or pollinator pan. We do have a few collection entries that are single bird captures and a blood and feather sample is part of the collection. Moving forward, a collection involving birds will be all birds captured at a site during one effort (mist-netting/box check). We also have a few plants - this is different from the plants in the herbarium. These are samples to be isotoped for the food web study. Whole plants will go into the herbarium but tissue samples go into our collection. Not sure if this is best practice but this is where I'm at. </p><p>Here's the summary of our collection </p><p><b>Entries </b></p><p>4241 entries</p><p>Megan O. entered 970 lines </p><p>Tyler S. entered 948 lines</p><p>Cally E. entered 586 lines </p><p>Becca K. entered 398 lines</p><p>There were about 10 other people that entered data - all less than 300 lines. </p><p>I entered 238 lines - wow, I have a lot to do to catch up (consider it takes 5 - 10 minutes per insect to enter). </p><p><b>Taxa</b></p><p><b> - </b>23 unknown phyla (this is an error - unless I really can't identify something to phylum)</p><p> - 2 annelids (worms)</p><p> - 4125 arthropods (no surprise there)</p><p> - 68 chordates (feather/blood, hair, scales)</p><p> - 16 flowering plant samples (should be many many more)</p><p> - 6 mollusks (all snails)</p><p> - 1 fern (a bracken fern, a common field fern) </p><p><b> Of the arthropods </b></p><p><span> - 185 spiders</span><br /></p><p><span><span> - 88 collembola (springtails)</span><br /></span></p><p><span><span><span> - 14 millipedes (this number seems really low but it's odd how few go into pitfalls compared to how many you see in the forest)</span></span></span></p><p><span><span><span><span> - 4 snails </span><br /></span></span></span></p><p><span><span><span><span><span> - 3828 insects </span><br /></span></span></span></span></p><p><span><span><span><span><span><span> - 3 Malacostraca (rolly-polly) </span><br /></span></span></span></span></span></p><p><span><span><span><span><span><span><b>Of the insects</b></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span> - 2 cockroaches (much much lower than expected)</span><br /></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span> - 428 Coleoptera (beetles)</span><br /></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span> - 1201 Diptera (flies)</span><br /></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span> - 574 Hemiptera (true bugs)</span><br /></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span> - 1239 Hymenoptera (bees, wasps, ants - most of these are ants and tiny wasps)</span><br /></span></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span><span> - 88 Lepidoptera (most were hand captures but also include a number of micromoths that are a few mm) </span><br /></span></span></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span><span><span> - 17 Odonata (dragonflies - all are hand captures)</span><br /></span></span></span></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span><span><span><span> - 138 Orthoptera (grasshoppers and crickets, mostly older samples from sweepnets) </span><br /></span></span></span></span></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span><span><span><span><span> - 50 mistakes (wrong orders listed with Insecta as the class, space added in front of the name or after)</span><br /></span></span></span></span></span></span></span></span></span></span></span></span></span></span></p><p><span><span><span><span><span><span><span><span><span><span><span><span><span><span><span><span> - identified to species 320 (not awesome) </span><br /></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></p><p><b>Moving forward</b></p><p><span> - add many more species identities </span><br /></p><p><span><span> - fix all the errors</span><br /></span></p><p><span><span><span> - send hundreds of samples off to be isotoped (~ 850 samples have isotope data) </span><br /></span></span></p><p><span><span><span> - sort and enter thousands of insects! </span></span></span></p><p><span><span><span>I do need a bunch of </span></span></span>https://www.forestry-suppliers.com/p/53598/52861/cornell-university-insect-cabinet-drawer.

Remarkable. It recently dawned on me how little time I seem to have for anything. The College of Science and Engineering was dissolved while I was away in the Galapagos so my position as dean (and associate dean) ended. Despite not having extra responsibilities (because I was teaching full-time as well) I feel like I have less time. Haven't been to the gym at all (and I feel and look it), I haven't sat down to do stamp stuff, and I haven't read a book. </p><p>I did </p><p></p><ul style="text-align: left;"><li>get to the Galapagos and Ecuador in May with a number of students and that well very well. </li><li>have pretty good research field seasons. In 2021, we focused on pollinator pans in burned, cut, and reference forests. In 2022, we focused on collecting specimens for an isotope study</li><li>have a paper get accepted into Ecosphere - this was originally rejected from Ecological Application</li><li>get promoted to full professor</li></ul><div>So not a spectacular year but a good year. I'll try and post the best photos from the Ecuador trip at some point. So time to access who I am and my increasing limits (i.e., how long can I stay awake or stomp through the forest). So here's are my goals to 2023</div><div><br /></div><div>I will</div><div><ul style="text-align: left;"><li>Finish off the three chapters for the coffee book </li><li>Submit an old data paper and a new data paper. Old data = my dissertation research from GA. New data is the yellow pollinator pan data. Would be great to get a third paper out but I don't want to be greedy</li><li>Push to have a big STEM event at Wilkes in May </li><li>Sort, sort, sort, and sort bugs. We're sitting on thousands of insects from dozens of samples. At worst, we will have samples for a food web study. At best... well... good question. Many jars are dried up.

This unit was cut at least one year ago. My understanding is that this is a shelterwood cut where the canopy is largely removed with just a few standing trees remaining. The unit can be found off Hwy 115 between Wilkes-Barre and Bear Creek. If you want to see Chestnut-sided Warblers or Prairie Warblers this is your spot! This area might had Golden-winged Warblers but I did not detect one (I didn't do any playback for them either). </span></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both;

I really haven't done either. I did one article review and my brain is not engaging fully. Still, I need to plan. </span></p><p><span style="font-family: verdana;"><b>Teaching</b></span></p><p><span style="font-family: verdana;">This spring I'll be teaching BIO 347 Biostatistics and Experimental Design and BIO 298 Economics of Conservation with a colleague from the Poli Sci department. As of now we're scheduled to teach in person but COVID rates are higher than they were in spring. Although vaccines have been approved I don't see widespread vaccine availability until mid-Spring. Just a guess though. One student in Biostats has requested remote teaching so I'll be recording lectures - live or otherwise. Live recordings ("synchronous") are easy because the camera is just recording me talking and I use my notes that are all ready to go. Asynchronous recordings require much more time - usually about 5 hours of work for 50 minutes of lecture time. </span></p><p><span style="font-family: verdana;">I'd also like to teach Field Zoology this summer but I'm skeptical it could happen. I haven't thought about it that much. Probably should soon. Also, I'd like to change it to Wildlife Techniques.</span></p><p><span style="font-family: verdana;">The fall semester is still up in the air. I will possibly teach Ecology. If not, I think Archosaurs again. </span></p><p><span style="font-family: verdana;"><b>Research</b></span></p><p><span style="font-family: verdana;">This spring I need to focus on DNA barcoding insects. It's gone horribly slow and it just comes down to following directions. We are also sorting insects from this summer's pollinator pan experiment. </span></p><p><span style="font-family: verdana;">This summer I need to survey birds in burned and unburned sites on gamelands. If I can have students we'll work at the same sites and catch bugs, birds, and mammals to work out food webs. I'll need to renew a zillion permits. My least favorite thing to work on. </span></p><p><span style="font-family: verdana;">I'd like to keep with the pollinator study. I started the pollinator project last August and it went exceedingly well. This coming summer I'll add a blue and white plate to the yellow plate I was putting out. Hopefully, by next summer I'll have better wasp ID skills and the barcoding will be down pat. </span></p><p><span style="font-family: verdana;"><b>Publishing</b></span></p><p><span style="font-family: verdana;">Clay caterpillar paper is in review. This has four or five students on it (all graduated). This was rejected the first time around and now resubmitted.</span></p><p><span style="font-family: verdana;">I have Ph.D. data I could try to publish on urbanization and birds. I have a ton of post doc data on bluebirds across an urban gradient. Those data are 15 years old. I have the pollinator data we're working on now - that won't be ready for weeks or a few months. There's the prescribed burning data - if anything that needs serious organizing.</span></p><p><span style="font-family: verdana;">Then there's the Wilson Ornithological Society. I'm the chair of the conservation committee and we've been struggling to come up with some initiatives. It looks like most of us want to publish. But what do we publish? Threats to birds? I think I'll put coffee growing forward as a topic and see if this gets some support. </span></p><p><span style="font-family: verdana;"><br /></span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPJeIOxXTfjdoshYtE4_31hQ-PrbQxP53eG0U2CVq5JKnEveeeijjrQXP8DeocB7CVtzPlLSg1bQK6O5eyPDgTtYVrdfk2vL0o4-JWiousLpGDWBW1DAdah9p6Bifc7zT7l6_O_QAKVpU/s2048/CC5D7847.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1365" data-original-width="2048" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgPJeIOxXTfjdoshYtE4_31hQ-PrbQxP53eG0U2CVq5JKnEveeeijjrQXP8DeocB7CVtzPlLSg1bQK6O5eyPDgTtYVrdfk2vL0o4-JWiousLpGDWBW1DAdah9p6Bifc7zT7l6_O_QAKVpU/s320/CC5D7847.JPG" width="320" /></a></div><br /><span style="font-family: verdana;"><br /></span><p></p><p><br /></p>Jeff Stratfordhttp://www.blogger.com/profile/09591299557480490379noreply@blogger.com0tag:blogger.com,1999:blog-4104168567969013632.post-84314934984945947122020-12-10T20:39:00.004-05:002020-12-10T20:39:59.357-05:00Reflections on 2020<h3 style="text-align: left;"><b><span style="font-family: verdana; font-size: medium;">Academics</span></b></h3><div><span style="font-family: verdana;">Stretching the brain a bit to go back to the spring. Here's what I remember. We took a number of students to Costa Rica in March for a class. Before the trip, I remember getting <a href="https://promedmail.org/" target="_blank">promed </a>emails about something happening in China and thinking nothing of it. By the end of the trip people were masked at the airport and furiously wiping down their area. I didn't know if they were over-reacting or I was clueless and underreacting - or a bit of both. </span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">It wasn't long after we decided to close for two weeks, then to the end of the semester, then we closed until we reopened for the beginning of the fall semester. I was also teaching biostatistics and <a href="https://www.youtube.com/channel/UCixxJOVPSN9-N1QUim6Mcxg">I recorded a few lectures</a>. </span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">This last semester was BIO 225 Population and Evolutionary Biology - I did a third of the class and the all the labs. We had the fewest students - 29 and only two sections of lab. Normally we have three and we did have four sections one year. Table tops had clear plastic sheets separating students and we all wore masks. One student did not want to come in so I worked her into the labs as much as possible. She was recorder when we were taking measurements. Worked to some extent although I firmly believe that learning to handle equipment (e.g., micropipetter and thermocycler, etc) are all handy skills (plus you come to understand the work that goes into research on a very visceral level). The one student submitted her work through the LIVE system and it was just a matter of logging in and checking the work. </span></div><div><span style="font-family: verdana;"><br /></span></div><div><span style="font-family: verdana;">I also had conservation biology. Although it could have been completely in person I recorded a number of lectures. I want to make this course completely online at some point (and add a lab). Something has to give (and now that I can't stay awake past 10 - more has to give) and I let the homeworks slide. Instead of 12 articles to read and answer questions I think they only had 4. That and 3 exams and journal club. I'd give myself a C+ for the course. </span></div><h3 style="text-align: left;"><b><span style="font-family: verdana; font-size: medium;">Research </span></b></h3><div style="text-align: left;"><span style="font-family: verdana;">This summer was about surveying burned and unburned sites in various state game lands. I covered new ground and hit a few sites I surveyed previously. This gives me more controlled data on how communities change through time (on short time scales). A few sites I wasn't able to get to but I hope to this coming summer. This makes the data messy but so it goes. I didn't employ the <a href="https://www.wildlifeacoustics.com/products/song-meter-sm4">Wildlife Acoustics </a>units. That was probably a mistake - they work great (but expensive). I also purchased a bunch of Audiomoth units. Much cheaper than Wildlife Acoustics but so far I'm not impressed. In fact, I have to get something recognizable off the units. I think they're really sensitive to moisture. The standard is to put them in a sandwich baggie and cross your fingers. I kid you not. </span></div><div style="text-align: left;"><span style="font-family: verdana;"><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAQ8mu_zyVqj1yXRqQXBpx2S8BkoVqCfI393dSIDrNuN7Rcd_LPUZAqbMDwZjulUQh0JsP0RjlhHahY8kWKS9wLu0cu-k4hJbX82uBexkO48CM8tG7CgBUYFRP1bxZpL1hwRzsNteQTAs/s2048/audiomoth.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2048" data-original-width="1536" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAQ8mu_zyVqj1yXRqQXBpx2S8BkoVqCfI393dSIDrNuN7Rcd_LPUZAqbMDwZjulUQh0JsP0RjlhHahY8kWKS9wLu0cu-k4hJbX82uBexkO48CM8tG7CgBUYFRP1bxZpL1hwRzsNteQTAs/s320/audiomoth.JPG" /></a></div><br />I just ordered an acoustic vent, which is a membrane that transmits sound but not water. I have small tuperware containers that I'll drill a hole in and place the vent over the hole. I'll post a pic when completed. </span></div><div style="text-align: left;"><span style="font-family: verdana;"><br /></span></div><div style="text-align: left;"><span style="font-family: verdana;">Towards the end of the summer I realized that I could easily study pollinators with pan traps. These are amazing. Simple, cheap, easy to deploy. A dream, yes? The problem is the wealth of data you get. </span></div><div style="text-align: left;"><span style="font-family: verdana;"><br /></span></div><div style="text-align: left;"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqkHdG0_FEJ7p1ns3dBSuCB5ZFCZGogkNa1X-lb7XbvGlGaNcMq4RxyTfgoC0wCIkRrhJOnorg_YcyCnq34R52bYf-6rZKZtT6b4mvggB6Nh5gDgQMfKE1Z5Ekr9PSeC0y1bD-NTNZp9c/s2048/pantrap.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2048" data-original-width="1536" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjqkHdG0_FEJ7p1ns3dBSuCB5ZFCZGogkNa1X-lb7XbvGlGaNcMq4RxyTfgoC0wCIkRrhJOnorg_YcyCnq34R52bYf-6rZKZtT6b4mvggB6Nh5gDgQMfKE1Z5Ekr9PSeC0y1bD-NTNZp9c/s320/pantrap.JPG" /></a></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: verdana;">The picture above was typical of a pan after 24 hours. That's right - 24 hours. I'll predict we get some 250 species of bee/fly/wasp. We're also DNA barcoding the insects to see who they are. So far that's been going meh. </span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: verdana;"><br /></span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: verdana;">Looks like the standard pan trap deployment is a combination of white, blue, yellow. I definitely want to do this next year so I need to up my pollinator ID skills. We're photographing everything as well but the iNaturalist crew has been slow to ID. </span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: verdana;"><br /></span></div><div class="separator" style="clear: both; text-align: left;"><span style="font-family: verdana;">I did submit a paper with five students as co-authors on Wednesday.

<span style="font-family: Trebuchet MS, sans-serif;">Finding my way around SGL38 and Bethlehem Water Authority I noticed non-burned areas that there cut so I decided to throw these in. I may not be able to find enough to say anything but they are a forest management strategy. A shelterwood cut is a clear cut with a few scattered trees left. At this site in Long Pond, they left oaks and pitch pine. These sites are great for Field Sparrow and Eastern Bluebird. The trees still had Black-and-White Warbler and Red-eyed Vireos. As this site becomes for shrubby, it might host Golden-winged Warblers, Blue Grosbeaks, and Yellow-breasted Chats. What I have noticed about PA's management strategy on game lands is that the scales are very large - hundreds of acres get the same treatment. But many birds will use various habitat types within their territory. Wood Thrush, for example, nest in small patches of an old opening that is filled with dense vegetation and they'll forage in areas with a closed canopy and open understory. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;"><b>Tuesday 6/16/2020 - off </b></span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><b><br /></b></span>
<span style="font-family: "trebuchet ms" , sans-serif;"><b>Wednesday 6/17/2020 and Thursday 6/18/2020 </b></span><b style="font-family: "trebuchet ms", sans-serif;">- SGL 38 </b><br />
<span style="font-family: "trebuchet ms" , sans-serif;">SGL38 is located in the Poconos and, apparently has many rattlesnakes. In fact, if you go back in this blog you'll find pictures of one I came across. Also the site that had a bear I estimate was over 600 pounds. The two days I was out had no bears and no rattlesnakes. Sites were burned in 2012 - 2014 but I suspect that this placed burned many times before that. It was covered in bear oak and pitch pine with all the hallmarks of having been burned (e.g., epicormic needs coming directly out of the bark). The density of towhees, Prairie Warblers, and Chestnut-sided Warblers is through the roof. No Golden-winged Warblers. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">One dimension I need to add to the research picture is the effect of cutting on bird communities. Thinning as a large effect on understory plant density and cut + burn makes for some interesting habitat. If they were to repeatedly burn, I think some grasses would move in and then they'd get Golden-winged. Just a guess. I remember my one and only GWWA on a territory and it was on a powerline in NJ (seen during my one and only World Series of Birding in 1990). Powerlines in the NE US have scattered shrubs, grasses and forest edges. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">This State Game Land straddles the Appalachian Trail just north of Reading, PA. It's a bit of a drive (1.5 hours) but it has plots that were burned in 2016, 2017, and a plot that will be burned in 2020. So I can get lots on information on birds and burning from one site. The other downer is the distance between sites. I walked almost 20,000 steps. Bird-wise wasn't very exciting but the burn sites were a joy to walk through since the fire took out the very dense mountain laurel. Was able to get 7 points in. Not great. Next time I should bring a mountain bike to take on the game road from plot to plot. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">Met with two colleagues about fancy ways to measure vegetation structure with LIDAR and drones. Still need to start getting measurements with some new (not newest) tools. </span><br />

<br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Bird surveys on SGL091. This section was cut and burned. Tons of birds and all the usual suspects for early successional forests, including Chestnut-sided Warbler, Common Yellowthroat, Field Sparrow. The last being one of the first birds to leave an area that converts to a forest. </span></li>

<span style="font-family: "trebuchet ms" , sans-serif;"><b>Tuesday (6/2/2020)</b></span><br />
<br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Went to survey SGL 326 which has three burning years (<a href="https://paprescribedfire.org/map">https://paprescribedfire.org/map</a>) so an ideal site if you want to know how bird communities change after a burn. The gate to the "road" was closed and I don't have permission to drive on the site so it was a bit of a bust. The nearest site was just over a mile walk and I don't just don't have it in me. </span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Met up with an ornithologist from the Schuylkill area and gave me back a camera I had left behind last year. Set on video and put onto a Wood Thrush nest. Lasted about three days and then stopped recording for whatever reason. Unfortunately, the angle was too high so we could only see the adults. Problem with nature - doesn't always give you the perfect opportunities</span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Went to the Jacob's property to check out the game cameras. Captured chipmunk, squirrel, raccoon and deer. Still hoping to get video of bear, beaver, etc. </span></li>
</ul>
<span style="font-family: "trebuchet ms" , sans-serif;"><b>Wednesday </b></span><br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Field day off. Three meetings. </span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Read a paper "<i><a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ele.13495?casa_token=q4ZDWlky8roAAAAA%3Awqo87OUDAv8dS8S5OdBlQpAYaMuf0KmMkpbkPYJ0qltjqItCsWBkoKEu4Mg_P-jCa1pXT3QuDWQ2HoiE" target="_blank">The worldwide impact of urbanisation on avian functional diversity"</a></i> in Ecology Letters. Great paper. Stats will take some time to figure out but interesting paper. </span></li>
</ul>
<span style="font-family: "trebuchet ms" , sans-serif;"><b>Thursday </b></span><br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Surveyed a few points on SGL91- same state game land as Monday but very different section near Pittston. Burned sites were logged then burned. The regrowth was shoulder height and just above. Soaked to the point of saturation - everywhere. I have data (I should) from when I surveyed in 2017. Last time I was here the trees were chest high and exceedingly thick - mostly oak saplings. Now the oaks are just over the my head slightly less dense as they start to self thin. The ground cover was slight (if one defines ground cover as <1 m from the ground). I think there fewer birds. We'll see. </span></li>

<br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Survey at SGL55. Some of it was cut over and burned (a mess) and some was just burned (glorious). Lot's of Hooded Warblers. Lot's of rocks flipped over by bears. Lot's of American Chestnut sprouts </span></li>

<li><span style="font-family: "trebuchet ms" , sans-serif;">Burn sites and reference sites</span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Least flycatchers were back - must have social breeding. Breeding site in the burned area - I suspect they don't care as long as the mid-story and canopy are intact. Lots of <a href="https://www.allaboutbirds.org/guide/Veery/id" target="_blank">Veery </a>in the unburned site. </span></li>

<li><span style="font-family: "trebuchet ms" , sans-serif;">found sites that were burned last year I didn't get to. Lots of hiking. There is a creek on a north facing slope that has huge hemlocks and very awe inspiring. </span></li>

<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">SGL207 - surveyed six points - 3 points that were burned </span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Walking to new sites heard a few Wood Thrush I didn't hear the day before. </span></li>
<li><span style="font-family: "trebuchet ms" , sans-serif;">Probably the second hardest day in the field in three years. The new sites were at least a km from the car and then several hundred meters apart. The slopes were steep and undulating. I wonder if there was copper mining at this in the past (at least 100 years ago). Huge granite boulders and slabs created lots of smaller cliff faces and caves. Shocked I didn't see bears or a rattlesnake. Did find a small patch of pink lady's slipper. The big problem of the day were the gnats. </span></li>

<br />
<ul>
<li><span style="font-family: "trebuchet ms" , sans-serif;">SGL13 - surveys 4 points that will be burned this year (at least scheduled to). Super dense blueberry bushes and swamp. Also, a branch swung up my nose and I gushed blood for a few minutes. Did see a huge (maybe 400 pounds) bear cross the road and head to where I surveying. Awesome. </span></li>

A safe date in this context implies that a bird you detect (hear/see) is a resident. This morning I will see hearing Scarlet Tanagers and Tennessee Warblers in my suburban neighborhood so these species are not within safe dates. I'm going to assume that nearly all species will be "safe" to survey by May 26. I have a bunch of project I can work on this summer that do not require students. All have advantages and disadvantages. I guess the larger goal is to do science that gets published. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;">For my mental state, I finished the semester much better year than I have the past two years. This is good. Still, a rapid transition from classroom (recently my sofa) to the field leaves no room for downtime. However, things have to happen. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">I'm leaning towards Fire and Bird Diversity. I have a state grant to study birds and prescribed burning but that research is put off a year due to COVID. Having the diversity part settled will allow me to focus on food webs next year when I can have students in the field with me. The big downer of this research is that State Game Lands are not in my backyard and I need to get at some sites at sunrise that are over and hour away. Oh well, there's always coffee. On the upside, I'm done by 11 (that's the protocol) so I can still work on papers (although when you're in bed by 7 I'm not super productive). I can also listen for Wood Thrush and look for their nests when wrapped up. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: trebuchet ms, sans-serif;">The more I think about it. The more I should the fire project. So be it. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;">I have started co-teaching a course on coffee. This is an interdisciplinary course and the other professor teaches some history of Costa Rica and Latin America as well as the economics of coffee. I teach the biology of coffee but narrowly (e.g., the parts of the coffee cherry = bean + surrounding fruit) and broadly (e.g., tropical climates, soil, photosynthesis). As part of the course, we go to the Tarrazu region of Costa Rica, which is southwest of San Jose. I wanted to make a post about the foods there - all of which were fresh from markets (at least the food we ate). We stopped at a market in Cartago and it was glorious! </span></div>

The meeting was fantastic and I was able to see a bunch of old friends from my tropical days and meet a bunch of new friends and there were many great talks. The two students that went with me did a great job presenting our poster. There were two big downers. One, a student was robbed by a taxi driver in Iguazu. She had to hand over her phone and wallet and he dropped her off along the road in the middle of a national park. Very not cool. Two, in Buenos Aires we were robbed by a taxi when our driver took off with our backpacks as we were removing our luggage. Now I've been taking pictures of taxi drivers and my photos are automatically uploaded. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">We're all told to back up our important documents and that I did. I had code on my hard drive and on a USB drive but both were stolen in the backpack - so I now I have everything on a Google drive and one other place. This will be my third place for this code. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;"><b>The problem</b>: So, let's suppose you're doing something ecological at a particular site and you have a bunch of those sites. If you are working in a heterogeneous system you might be interested in the interaction between what is happening at a site and the landscape around the site. Since what constitutes the landscape is nebulous, we can examine the effect of spatial extent on site properties. For example, take the decision of a bird to use a bird house or not. The bird likes trees around the nesting site but does it need to be a forest or just a woodlot? I often refer to larger spatial extents as the context (city, forest, suburban) and smaller spatial extents of local conditions (e.g., a woodlot in a city, a parking lot in the country, and, of course, a woodlot in the woods and a parking lot in the city). So maybe the bird's decision is based on context or local conditions or a combination (much much tougher to sort out since everything in the landscape tends to correlated). </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;"><b>The general approach</b>: Your ecological points need to geo-referenced in a spreadsheet. To that we will add land use information that we will extract from remote sensing. Then we can run statistics linking the ecological information to the land use. A focal analysis is used where a sampling point serves as the center of a circular buffer. We will count the number of pixels and estimate the proportions of land cover by the relative number of pixels. We will use a 1000 m buffer and a 200 m buffer nested within the large buffer. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;"><b>The land use data set: </b>I use the NLCD 2016 Land Use data from the <a href="https://www.mrlc.gov/viewer/" target="_blank">MRLC website</a>. The map is a raster image (matrix of pixels with numbers representing different land uses). Each pixel is 20 x 20 m pixels so a few km can represent a great deal of data. The image below is roughly, the whole spatial extent that I work. The red banana is the Scranton/Wilkes-Barre greater urban area (aka "The Valley"). To the east is NJ and NY to the northeast. The squiggly line leading to the Scranton/Wilkes-Barre area is the North Branch of the Susquehanna. </span><br />

<span style="font-family: "trebuchet ms" , sans-serif;">I like examining how ecology changes over a gradient and, unfortunately, the Scranton/Wilkes-Barre area does not really have much of a gradient. The red is high intensity urban and green is forest. You can see that The Valley is intensely urban and the area surrounding the value is very green and beyond that a mix. That ring of green around The Valley is the steep slopes of the surrounding land that is heavily forested (which is nice). To the west and north is farm land (yellow) and to the east and south is a mix of small towns, lakes, and game lands. </span></div>

We put out 20 at a site and those sites are georeferenced with lat and long recorded in degrees decimal (e.g., 72.234). We go back a week later and count to the bite marks to get a predation rate.</span></div>

There are two problems I keep encountering and it takes <u>several days</u> of searching to find an appropriate data set - if ever. Here's the issue - most data sets built into R are ready to be crunched but they are often irrelevant to the student. For example, the two commonly used data sets that are in R are cars (just what it sounds like) and iris. The latter is flower but decades old. I'm looking for something from year >2000. There are a few data repositories, such as <a href="https://datadryad.org/stash" target="_blank">Dryad</a>, that are current but the data are often too complicated for simple analyses like ANOVA, t-test, etc. There are data sources that are huge but not very useful (unless you are a political scientist) like health data from the UN and WHO that are already summarized (but needing to merged with other data such of economic data. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">It would be great to have a searchable database for data sources that you can select the response variable type (e.g., continuous, binary, etc) and the predictor variables (e.g., continuous, binary, random) and maybe the year. That would be amazing and I think it would help the hundreds... thousands of people teaching statistics. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">This is not that data base but maybe I can start to link data sets to techniques used</span><br />

<span style="font-family: verdana;">I've decided to put a large portion of my conservation biology lectures online. They will be slightly less detailed than what I would normally do in class but I will make up for by extra readings. I asked a few of our graduates in graduate school what we were missing and one theme was reading and critiquing the peer-reviewed literature. So that will be part of the course that's for our students but not the public. By what not have public lectures. Maybe I'll get some good feedback. </span></div>

My head isn't above water yet work wise and hoping this can help me focus again.</span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">So let's talk about murder. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">When I was at Auburn in the early 2000's a friend of mine was studying bluebirds and she told me a house sparrow had killed a number of bluebirds in the box. I thought maybe this was unique to bluebirds and house sparrows but then I had some 100 boxes with bluebirds and no murders from 2009 until now. </span><br />
<span style="font-family: "trebuchet ms" , sans-serif;"><br /></span>
<span style="font-family: "trebuchet ms" , sans-serif;">Until now. </span><br />

<br />
<ul>
<li><span style="font-family: Trebuchet MS, sans-serif;">finish a review that mostly involves code</span></li>
<li><span style="font-family: Trebuchet MS, sans-serif;">grade exams </span></li>
<li><span style="font-family: Trebuchet MS, sans-serif;">finish coming up with the biostats lab assignment (t-tests and such with bluebird data that I collected 10 years ago)</span></li>
<li><span style="font-family: Trebuchet MS, sans-serif;">come up with a great talk by Saturday for the state blue bird society. I'm thinking of what we know and don't know about bluebirds </span></li>
<li><span style="font-family: Trebuchet MS, sans-serif;">figure out what to do with study abroad. We have three $5000 awards to give out and only one application.</span></li>

I've been involved in producing three posters:</span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Poster 1: grassland research and the relationship between plant diversity and bird abundance and diversity (displayed Tuesday)</span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Poster 2: how acorns differ (or not) their chemistry over latitudes and how weevils that infect acorns also vary over latitudes (displayed Tuesday) </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Poster 3: how urbanization affects dispersal distance and the proportion of acorns that are eaten versus cached (displayed tonight) </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">On Tuesday night, we put our two posters up and looked at them with pride. We used mixed model regression, multivariate regression, fancy method. Then the other posters from other departments went up - these were from business and nursing. I smiled smugly on the inside with our fancy posters. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Then overnight it hit me. Our posters were terrible. TERRIBLE. The point of this exercise was to inform other departments of what we do. In that way, I can't imagine that a nurse was interested in our R-squares or our literature cited or the multivariate output. In neither poster did we explain why any of this is important for either society or science or both. In none of these posters do explain some of the possible really interesting implications. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Also, our methods were all words. ZZZZZZZ. Is anyone going to read it? Probably not. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: "Trebuchet MS", sans-serif;">So I'm scrambling to change the poster that's put up today. Let's see how it goes. </span>Jeff Stratfordhttp://www.blogger.com/profile/09591299557480490379noreply@blogger.com0tag:blogger.com,1999:blog-4104168567969013632.post-21061502245348911302017-03-18T20:55:00.001-04:002017-03-18T20:55:38.174-04:00On deck for the week 3/19/17<span style="font-family: Trebuchet MS, sans-serif;">You'd think with four days off at work I'd be ahead. Never underestimate my ability to waste time. Worst part: did nothing with the puppy.</span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Things on my agenda for the week coming up</span><br />

So it goes. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">This is something that has been bugging me for over a decade. If you look at the relationship below which shows how native bird diversity changes with urbanization. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Urbanization is quantified as the amount of impervious surface a km around where they were counted. The data are transformed but the whole scale goes from 0% to 100% (just take the sine of any of those numbers to transform back into a percent). </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Note that the relationship is positive from 0 to 20% and negative >20% urbanization. The post 20% is easy to understand: as urbanization comes to dominate a landscape, native birds find fewer habitats. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">Less than 20% there is little urbanization. That's easy to get. But what is there? In a real complex landscape, where there is not city there can be anything. It can be completely forested, agriculture, suburban, a mix of all the above. I think that explains all the noise on the low-urbanization side. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">I think what's lacking - in any statistical approach that I'm aware of - is how to model with factors whose effect can vary with their values. So in this case, I bet species richness increases with urbanization at first because a little bit of urbanization adds some birds associated with urban habitats but there's still enough natural habitat to have those birds persist but as urbanization increases the natural habitat gives way and birds are lost. </span><br />
<span style="font-family: Trebuchet MS, sans-serif;"><br /></span>
<span style="font-family: Trebuchet MS, sans-serif;">So I need to invent a statistical method. </span><br />
