Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...

Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size ( N e ) is a useful measure for quantifying genetic drift. Evaluating relative contributions of different demographic factors to N e is therefore important to identify what makes a population vulnerable to loss of genetic variation. Until recently, models for estimating N e hav...
