Daniel’s research featured in Nature Ecology & Evolution

Just-arrived postdoc Daniel Hooper has a paper from his dissertation newly out in Nature Ecology and Evolution entitled Chromosomal inversion differences correlate with range overlap in passerine birds. Abstract is copied below, but his ‘behind the paper’ article in the same issue is also very much worth a read. Abstract:…

Stepfanie’s paper makes the cover of PLOS Genetics!

Grad student Stepfanie Aguillon’s paper is featured on the cover of the current issue of PLOS Genetics. Here is what that journal has to say about her contribution: Florida Scrub-Jays reveal new details about isolation-by-distance. The pattern of isolation-by-distance is observed often in nature, but we rarely have means to…

Stepfanie’s dispersal genomics paper is out in PLOS Genetics

Grad student Stepfanie Aguillon’s newest paper is now out in the journal PLOS Genetics — where it was released just 1.5 hours before she gave a talk on it at the AOS conference at Michigan State. The paper titled “Deconstructing isolation-by-distance: The genomic consequences of limited dispersal” shows how the…

Natalie, Dave, and Scott review discoveries about the genetics of carotenoid coloration

Spurred by several exciting findings in warblers and canaries, current lab members Dave Toews and Natalie Hoffmeister, and lab alum Scott Taylor, reviewed what is known about the evolution and genetics of carotenoid processing in animals in a paper just published in Trends in Genetics. Animals cannot synthesize carotenoids and…

Nick on assessment of academic support programs

Graduate student Nick Mason recently published a paper with lead author Cissy Ballen to examine the effects of a campus support program for underrepresented minorities, first-generation students, and women in biology: the Biology Scholars Program (BSP) at Cornell. Together, Cissy and Nick found evidence of a disparity in preparedness among…

New paper by Jen Walsh et al on sparrow diversity

Postdoc Jen Walsh and collaborators recently published a paper in Molecular Ecology investigating the genetic structure of the Saltmarsh-Nelson’s sparrow subspecies complex. Using a reduced representation sequencing approach coupled with morphological data, this study offers the first comprehensive view into subspecies variation within Saltmarsh and Nelson’s sparrows. The authors found…

Jen Walsh et al. on the conservation genetics of sparrows

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…

Nick publishes on damselfly behavioral ecology

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…

Nick’s paper on song evolution and diversification is out in Evolution

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…

Molecular Ecologist features Stepfanie’s new paper on IBD

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…

Hope’s honors thesis is published in The Auk

Congratulations to alumna Hope Batcheller for getting her undergraduate honors thesis all the way through to publication! Hope’s project on interspecific communication among ant-following birds in lowland Amazonia started with a semester-long directed reading seminar class on the existing research about ant-following birds, when then led Hope to design field…

New paper on turtle dove evolution

Visiting scientist Luciano Caldarón, our own Leo Campagna, and a cadre of collaborators just published a paper showing that the European Turtle Dove shows genetic evidence of a fluctuating demography over time, and is currently undergoing a shrinking phase. The combined effect of demography, habitat destruction and hunting is causing…

David on species limits in the Yellow-rumped Warbler complex

I’m tardy to post here that postdoc Dave Toews recently published an ornithologically quite noteworthy paper in the Auk: Ornithological Advances from his PhD work at the University of British Columbia with Darren Irwin. Their study found evidence of strongly heterogeneous genomic divergence between a number of groups in the…
