resource defense polygyny

a form of polygyny in nonhuman animals that can occur when some males defend areas containing sufficient resources to allow a number of females to breed successfully. A male defending sufficient resources is able to benefit from polygyny not by being more attractive or having better genes but because the resources he controls can feed multiple females and their offspring.
