Experimental evidence for homeostatic sex allocation after sex-biased reintroductions

ABSTRACT First principles predict negative frequency-dependent sex allocation, but it is unproven in field studies and seldom considered, despite far-reaching consequences for theory and

practice in population genetics and dynamics as well as animal ecology and behaviour. Twenty-four years of rhinoceros calving after 45 reintroductions across southern Africa provide the

first _in situ_ experimental evidence that unbalanced operational sex ratios predicted offspring sex and offspring sex ratios. Our understanding of population dynamics, especially

reintroduction and invasion biology, will be significantly impacted by these findings. Access through your institution Buy or subscribe This is a preview of subscription content, access via
