Researchers at the University of Exeter have found that sexual conflict over mating impacts the parental care behaviour and reproductive productivity of burying beetles.
These beetles have surprisingly complex parental care, similar in form to that provided by birds such as robins or blackbirds, with offspring begging to be fed by touching parents, who respond by regurgitating partially digested food.
Both males and females provide parental care, but females are the primary care givers, as in humans. So anything that affects the ability of females to provide parental care, such as costly mating, is likely to reduce overall reproductive productivity. (more…)
