Postdoc Jen Walsh and collaborators recently published a paper in Conservation Genetics investigating the temporal stability of the Saltmarsh-Nelson’s sparrow hybrid zone. By comparing genetic, morphological, and survey data from the same sites from two time periods (1998 and 2013), this study finds that Nelson’s Sparrows are moving further south…
We are back from two exciting weeks in Patagonia where Irby and Leo have led for the second consecutive year the field-course portion of “BioEE2525/BioEE2526 Ecology and Conservation of Wildlife in the Neotropics”. Together with co-leaders Roxanne Razavi, David Toews, Natalia García and a group of 12 Cornell students, we…
Graduate student Nick Mason recently published a manuscript on damselfly behavioral ecology that appeared in Animal Behaviour. Nick’s manuscript is the product of his time with the Cornell Florida Field Course, which facilitates short research projects for graduate students at the Archbold Biological Field Station in south-central Florida. In this…
Graduate student Nick Mason and collaborators recently published a paper in Evolution about diversification, rates of song evolution, and vocal learning in passerine birds. By combining two large vocalization data sets, this study finds a positive association between accelerated bursts in speciation and vocal evolution. Furthermore, the authors find evidence…
The well-read Molecular Ecologist blog by Jeremy Yoder — which is loosely affiliated with the Molecular Ecology journal — just ran a really great commentary featuring a new paper posted on bioRxiv by grad student and lead author Stepfanie Aguillon. The title of the original paper is Deconstructing isolation-by-distance: the…
Postdoc Jen Walsh has been awarded a $12K seed grant in support of her work on the genomics of parallel adaptation in salt-marsh-dwelling sparrows. We are particularly grateful to the Cornell Center for Vertebrate Genomics for this specific award and more generally for creating an interactive network of scholars from…
Graduate student Natalie Hoffmeister just returned from a pilot field season chasing after Imperial Shags in Patagonia, and she’s now even more eager to return for another season of sampling. This project may grow into her dissertation, focusing on population structure and salt tolerance in (Phalacrocorax atriceps) near Ushuaia, Tierra…
