Dietary adaptation of FADS genes in Europe varied across time and geography
Fatty acid desaturase (FADS) genes encode rate-limiting enzymes for the biosynthesis of omega-6 and omega-3 long-chain polyunsaturated fatty acids (LCPUFAs).

Positive selection on FADS genes has been reported in multiple populations, but its cause and pattern in Europeans remain unknown. H...

The Geography of Fear: A Latitudinal Gradient in Anti-Predator Escape Distances of Birds across Europe
All animals flee from potential predators, and the distance at which this happens is optimized so the benefits from staying are balanced against the costs of flight. Because predator diversity and abundance decreases with increasing latitude, and differs between rural and urban areas, we should expect escape distance when a predator approached the individual to decrease with latitude and depend...
