A postdoc position is available to work on historical DNA from bird sub-fossils, museum skin specimens and fresh samples to develop a novel real-time assessment of genetic response to anthropogenic environmental change across multiple bird species following first human arrival in a pristine environment. The time series is designed to examine the long-term processes leading to variation in extinction risk between closely related species, comparing differences in demographic and selective responses to common environmental changes. The position is part of the project "Suscept-Ext: Understanding susceptibility to extinction using historical museum series as a genetic time series", funded by the French National Research Agency (ANR), that links competences of two research centres in France.
