A rapid koala rebound in southeastern Australia is also boosting their genetic variation, showing one way out of an extinction death spiral. After nearly disappearing from the region over a century ...

Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that ...

A long-term fish experiment reveals how a mechanism called density dependence, in which the population growth rate slows as the number of individuals rises, affects population dynamics on time scales ...
