Antechinus
Breeding occurs in winter (usually August–September) at a time when
there is little food available in the environment, and in order to
ensure breeding success, male antechinuses strip their body of vital
proteins and also suppress the immune system so as to free up additional
metabolic energy. In this way an individual male trades away long-term
survival in return for short-term breeding success, and following the
breeding season there is a complete die-off of physiologically exhausted
males. Breeding is intensely competitive. Males produce large amounts of
testosterone and mate-guarding occurs in the form of protracted
copulation (up to twelve hours in some species).
