Bigger, badder males drive unbalanced genetic introgression in wall lizards

Female mate choice is one of the major barriers to hybridization. But even when hybridization does happen, females are often identified as the primary drivers of how phenotypes move through a hybrid zone. A new paper appearing in Ecology Letters … Continue reading

Machine learning for model selection in population genomics

The application of model-based methods in phylogeography helped the field transition from a more qualitative, overlay-a-tree-on-a-map, discipline to one that tests hypotheses in robust statistical frameworks. Many researchers have embraced approximate Bayesian computation (ABC) for model selection since computing the likelihood of … Continue reading

Measuring dispersal rate in Neotropical fishes in units of ‘wallace’

Alfred Russel Wallace often gets second billing compared to Charles Darwin but in a paper recently accepted at Systematic Biology, Tagliacollo et al.  define a new term for their analyses (dispersal rate, D) and measure D in units of ‘wallaces‘ (wa) to honor the contributions of Alfred … Continue reading

Survival of the fittest: a marine snail toughs it out through a salty time

For marine organisms, salinity plays an important role in determining how populations and species are distributed across time and space, particularly in the Mediterranean Sea. During the Mesozoic, about 252 to 66 million years ago, the Tethys Ocean, a body … Continue reading

Inferring kinship from low coverage sequencing data

Knowing the relatedness structure of your population is essential for pretty much any study. Until recently, the only way to determine the kinship structure was to have a detailed pedigree or to estimate relatedness (poorly) using microsatellites. The spurt of … Continue reading
