Reproductive biology: Out with a bang
Stuart Humphries1 & David J. Stevens1,2
Abstract
Not many mammalian males die soon after mating — the phenomenon was thought to be limited to certain small marsupials. Its occurrence in a larger marsupial overturns previous ideas about why the strategy exists.
Semelparity is the so-called big-bang reproductive strategy, in which an animal invests all in a single mating season, dying soon afterwards. This is not a strategy one immediately associates with mammals.
