The current members of our lab group who are at the Evolution meeting in Portland this week: Leo Campagna, Nick Mason, Gavin Leighton, David Toews, Petra Deane-Coe, Shawn Billerman, Jen Walsh, Stepfanie Aguillon, and Eliot Miller. Add in a few talks by researchers from other countries who visited our lab…
Graduate student Stepfanie Aguillon presented a poster at the Evolution conference on her genomic investigations into the hybrid zone of yellow-shafted x red-shafted flickers. Contrary to all previous forays on this topic, Stepfanie is finding markers that differentiate these forms and that may be associated with their color differences and…
Postdoc Jen Walsh just presented at the Evolution conference in Portland on her ongoing studies of adaptation and gene flow among Saltmarsh and Nelson’s Sparrows.
Postdoc Dave Toews gave a second talk today at the Evolution conferenece, in which he discussed cases of mitochondrial and nuclear discordance in warblers: In yellow-rumped warblers where mitochondrial DNA has introgressed between two forms, and in golden and blue-winged warblers, where mitochondrial DNA is distinct in the face of…
Graduate student Petra Deane-Coe presented a talk at the Evolution conference today in Portland. Petra covered her studies of local adaptation in Swamp Sparrows and her careful exploration of its underlying genetic basis, based on comparisons among whole-genome datasets from sparrows that are adapted to saline marshes versus others that…
Leo Campagna gave a talk today on the genomic architecture of phenotypic differences in capuchino seedeaters. The study (recently published in Science Advances) shows that there are very small genetic differences among these species and that they tend to center around regions that are likely to control the expression of…
Grad student Nick Mason is presenting his work today at the Evolution conference in Portland. This component of Nick’s dissertation looks at the surprisingly complex history of a group of seedeaters, and was done in collaboration with several colleagues from Mexico.
Postdoc Shawn Billerman is presenting his work at the Evolution conference in Portland. This component of Shawn’s study compares the climate niches of several Great Plains hybrid zones and tracks how they have changed over the past 60 years.
Catalina Palacios, a PhD student from Daniel Cadena’s lab group in Colombia, is finishing her six-month research visit by talking about the genomic results from her study of two hummingbird species. Catalina’s work shows how whole genome sequencing can help distinguish hummingbird species that resisted delimitation with other techniques (mtdna…
Postdoc David Toews gave a 5-minute blitz talk today at the Evolution conference on the topic of “How hybridization structures the genomes of related birds”.
Sebastián Cabanne gave a talk today at the Evolution meetings in Portland on the historical phylogeography of the atlantic forest and andean forest biomes. He used data generated in part in our lab during two visits (2014 and 2016) to study patterns of isolation and connectivity in two co-distributed passerines.…
Irby Lovette was honored with Cornell’s Kendall S. Carpenter Memorial Advising Award during this past graduation weekend. The awards, which are given each year to four faculty from across the campus and which are Cornell’s highest recognition for advising, underscore of the importance of engagement with undergraduates and are based…
Grad student Stepfanie Aguillon and her collaborators presented a poster this week at the national Teaching as Research Conference. Their study used undergraduates on our Introductory Evolutionary Biology course to explore gender-based differences in student participation. Among the main take-aways: male and female students interact differently in the classroom, with…
Lab associate John Sullivan and undergraduate Madi Rich, along with colleagues, published a paper this month in the Zoological Journal of the Linnean Society that describes a ‘lost’ species of electric fish from the Ogooué River of Gabon. A nice write-up on this project is on the Cornell Chronicle site…
