Sex and the drought [PDF]

open access: yesCurrent Biology, 2008
SummaryAsexual taxa, such as the bdelloid rotifers, are anticipated to help answer the question of what makes sexual reproduction so prevalent and persistent. But perhaps the secret of some asexuals' success lies in their ecological oddity. Florian Maderspacher takes a look.
