Data from: Population genomics shed light on the demographic and adaptive histories of European invasion in the Pacific oyster, Crassostrea gigas

Audrey Rohfritsch, Nicolas Bierne, Pierre Boudry, Serge Heurtebise, Florence Cornette & Sylvie Lapegue
Crassostrea gigas originated from the Pacific coast of Asia but was introduced into several European countries in the early 1970s. Natural populations have now spread the length of the western seaboard of Europe. To elucidate the demographic and selective processes at play during this rapid expansion, genome-scan analysis was performed on different populations. High diversities and low differentiation were observed overall, but significant genetic differentiation was found among newly-established populations and between the newly-established northern...

Although it is generally agreed that the arctic flora is among the youngest and least diverse on Earth, the processes that shaped it are poorly understood. Here we present 50 thousand years (kyr) of arctic vegetation history, derived from the first large-scale ancient DNA metabarcoding study of circumpolar plant diversity. For this interval we additionally explore nematode diversity as a proxy for modelling vegetation cover and soil quality, and diets of herbivorous megafaunal mammals, many...
