A team of researchers from the National University of Singapore has found that the effective population size and genetic diversity of Singapore’s Cynopterus brachyotis, believed to remain widely unaffected by urbanisation, has shrunk significantly over the last 90 years – revealing that the current biodiversity crisis may be much broader than widely assumed, affecting even species thought to be common and tolerant of fragmentation and habitat loss.

Genetic mechanisms that create and maintain variations in female preference has been one of the central questions in evolutionary ecology.
