Bridging the conservation genetics gap to save Britain’s last wild-living felid

About the author: Dr Helen Taylor is a conservation geneticist who studied for her PhD in New Zealand, working on inbreeding in little spotted kiwi. She went on to undertake postdoctoral research on inbreeding and male fertility in passerines and, at that point, became interested in the integration of genetics into conservation management. After eight years […]

Revealing ancient hybridization’s role in diversification

Hybridization between closely related species is a rapidly emerging field of interest for evolutionary biologists, and the more scientists look for signals of hybridization (with ever fancier tools), the more we learn that hybridization is the norm rather than the exception (Payseur & Rieseberg 2016). While young species pairs tend to hybridize more readily than […]

Three’s not a crowd! Does genetic variation across a tri-species hybrid zone respond to environmental differences across the landscape?

Hybrid zones elucidate the barriers to interspecific reproduction, the raw material for speciation, and thus are unparalleled resources for evolutionary biologists (Harrison 1993). However, when hybrid zones appear to lack reproductive barriers to gene flow, they pose a different set of questions, for example, what are the historical and contemporary factors which facilitate gene flow […]
