Congrats Nick – a year late!

Nick Vinciguerra is back in San Diego for a visit, so this gave us a chance for a little in-person celebration of his MS defense since we couldn’t celebrate in person last year. Organized by Jenna – a little bird hike at Mission Trails Park (with a surprise hooding!), followed by lunch and cake a Eureka. Congrats Nick!

Burns Lab Updates Spring 2021

Time for an update of Burns lab news from the past 6 months. First off, I would like to highlight three recent papers by Burns lab students:

Nick Vinciguerra published one of the chapters of his MS thesis, looking at bill evolution in tanagers:

Bill diversity in tanagers, from Vinciguerra et al. 2021

Amelia Demery published one of the chapters of her MS thesis, together with former Burns lab student Nick Mason. She looked at the interplay between song and bill evolution in tanagers:

Brian Myers published another paper from his dissertation. This paper focused on Allen’s Hummingbirds, highlighting their colonization from the Channel Islands to mainland California. He also wrote a blog post about it.

In addition to papers, huge congratulations to Sarah Hood who received a NSF Graduate Research Fellowship. Sarah just finished the second year of her MS studying population genetics and migration in the Allen’s Hummingbird.

Congrats also to Burns lab undergraduate Aubtin Rouhbakhsh who was admitted to the graduate program at the University of Hawaii. We wish Aubtin the best of luck!

Congrats to graduate student Michael Tofflemire who received a grant from LA Audubon’s Schreiber fund for his dissertation research on the comparative phylogeography of California birds.

Lastly, starting in late March, we were able to resume in-person Ornithology class field trips. It was great to take students in the field again. Below are some photo highlights. Check this link for some more pictures of Ornithology class field trips this year and previous years.

Burns Lab Updates

It’s been a while since I updated this page, but a lot has happened in the Burns lab in the past 1.5 years or so. Of course, Covid has been challenging, but we are still continuing, and there are many good things to celebrate. Here are some highlights:

PhD student Brian Myers successfully defended his dissertation and completed an internship with the USGS. He has recently started a post-doc with Liz Scordato at Cal Poly Pomona.

MS student Nick Vinciguerra successfully defended his thesis in Summer 2020 and started a PhD program in the lab of Mike Anderson at the University of New Mexico.

MS student Ben Scott received research grants that allowed him to visit museums to gather plumage color data from cardinals for his project. He successfully defended his MS proposal in summer 2020 and is well on his way to finishing his degree in Spring 2021.

MS student Sarah Hood started in the Burns lab in Fall 2019. Since arriving, she has received an AOS award for her project on Allen’s Hummingbird subspecies and migration and has completed much of the field work for her project.

PhD student Michael Tofflemire joined the Burns lab in Fall 2020. He came to the lab from the University of Washington, where he worked in the lab of John Klicka on phylogeography of the Black-throated Gray Warbler.

Undergrad Aubtin Rouhbakhsh presented results of his research on Rufous x Allen’s Hummingbird hybrid zone at the 2020 SDSU Student Research Symposium. He graduated in May and is currently applying to graduate school.

We had a great spring semester of Ornithology, even though we had to make the switch to online learning mid-semester. The students of course were disappointed with the loss of the field component, but they all handled the transition well and we had some great field trips before the shutdown.

Two publications I would like to highlight:

Brian Myers published the first chapter of his dissertation in the Auk (now called Ornithology). This chapter focused on behavior and morphological changes across the Allen’s x Rufous Hummingbird Hybrid Zone.

Former Burns lab student Rosalyn Price-Waldman published the first chapter from her MS thesis in Evolution. She co-authored this work with another former Burns lab student, Allison Shultz, who is now the curator of birds at the Natural History Museum of Los Angeles County and also and adjunct at SDSU. The paper showed that speciation rates are correlated with changes in plumage color complexity in tanagers. 

Figure from Rosalyn and Allison’s paper looking at color complexity and speciation in tanagers:

Congratulations Rosalyn!

Congratulations to Rosalyn Price-Waldman for successfully defended her MS thesis. Her project investigated the interplay of natural and sexual selection in diversification. Rosalyn will begin working on her PhD in Cassie Stoddard’s lab at Princeton this fall. She will be missed and we wish her the best of luck!

Welcome Ben!

The Burns lab welcomes new MS student Ben Scott. Ben received his Bachelor of Arts in Biology from Occidental College. While at Occidental, Ben worked in the Moore Lab of Zoology with John McCormack on phylogeny and trait evolution of New World Jays. Ben also spent some time working at the Western Foundation of Vertebrate Zoology, home of the largest egg collection in the world. Welcome Ben!

Rosalyn at Molecular Evolution Workshop

Rosalyn had a busy summer, starting with two weeks working with collaborators in the Faircloth lab at LSU and ending with ten days at the Marine Biological Laboratory’s Workshop on Molecular Evolution in Woods Hole, MA. The workshop provided an overview on topics in molecular evolution including phylogenetic inference, population genetics, comparative genomics, and much more. One focus of the workshop was hands-on instruction in the latest software, often by the authors of the programs. The workshop was an incredible experience, and Rosalyn is excited to apply what she learned to her thesis work on the phylogenomics and trait evolution of tanagers.

Origin of Darwin’s Finches

Darwin’s finches are a classic example of adaptive radiation, but few studies have attempted to reconstruct the biogeographic origins of Darwin’s finches. Burns lab MS student Erik Funk studied this question in the third chapter of his thesis which was published last month in the Auk (and put on the cover). This study revisited an early paper by Kevin Burns, Shannon Hackett, and the late Nedra Klien (Burns et al. 2002). The earlier study showed that Darwin’s finches likely originated from a Caribbean species, given that so many of their close relatives are found in the region. Erik’s paper provides an important update, with improved biogeographic methods and a newer phylogeny. Erik’s results were a bit more equivocal than the 2002 paper. Although a Caribbean origin is plausible and likely, a South American origin can not be ruled out. You can read the paper here, and there was also a nice summary of the overall question and Erik’s results in the Guardian.
