Greater sage-grouse at lek, with multiple males displaying for the less conspicuous females.

This paradox arises from the expectation that ...

In sociobiology and behavioural ecology, the term "mating system" is used to describe the ways in which animal societies are structured in relation to sexual behaviour. The mating system specifies which males mate with which females, and under what ...
