Panamanian golden frog skin microbiota predict ability to clear deadly infection

The fungal skin infection, Batrachochytrium dendrobatidis (Bd), has pushed many amphibian species to the brink of extinction. One such species, the Panamanian golden frog, is likely extinct in the wild and has been maintained in captive breeding colonies since 2006. … Continue reading

A love letter to sponges

Like many kids interested in marine biology, growing up I wanted to work on sharks. After college I interned for a year at the Center for Shark Research at the Mote Marine Lab under the guidance of two great mentors, Jim Gelsleichter and … Continue reading

British fineSTRUCTURE

Leslie et al. (2015) provide an analysis of genome-wide SNP data from over 2,000 individuals in the United Kingdom in a paper out this week in Nature. The population structure in the UK was limited with FST estimates averaged 0.0007, with a … Continue reading

Reviewing the reviews: Twelve years of Landscape Genetics

Landscape genetics has grown feverishly since its first formal definition in 2003 (Manel et al). The beauty of combining genetic, environmental, and spatial variation to answer biological questions sure is alluring, and the quest for improving the methodology of landscape … Continue reading

Behavioral individuality reveals genetic control of phenotypic variability

Studies of animal personality (or, “behavioral syndromes”, if you choose your words carefully) are so hot right now. One of the assumptions of such studies is that natural selection has somehow favored this behavioral variability/plasticity (and not just differences in … Continue reading

This is your brain on Human accelerated regulatory enhancer (HARE5)

Four decades have passed since King and Wilson published their seminal paper “Evolution at Two Levels in Humans and Chimpanzees“. In it, they proposed that the large behavioral and morphological differences between us and our closest relatives, chimpanzees, could not … Continue reading

Show me the power

Describing the patterns of genetic structure and mating system variation in presents challenges from the outset of sample collection to data analysis (see this post and this post). At the beginning of February, I had the pleasure to collaborate with Sean … Continue reading

Interspecific gene flow enhances vectorial capacity

There are charismatic cases of gene flow between species, such as Neanderthals (see also Arun’s posts here and here), but the role of introgression in evolution remains poorly documented. Recently diverged species have incomplete reproductive isolation and can hybridize. Rapid … Continue reading
