What is female Philopatry?
Introduction. In most mammals, females show philopatry, i.e. settle for life in or near the area in which they are born, whereas males disperse (Greenwood 1980; Waser and Jones 1983; Pusey and Packer 1987; Lawson Handley and Perrin 2007).

What are three factors that impact primate feeding success?
- quality of food – Quality of food is determined by the amount of nutrients it provides. …
- distribution of food – Where the food is located across the landscape can impact female primates’ feeding success. …
- availability of food – Where and when food is available can be highly variable, depending on location.
What causes philopatry?
The causes of philopatry are numerous, but natal philopatry, where animals return to their birthplace to breed, may be the most common. … In an animal behavior study conducted by Paul Greenwood, overall female mammals are more likely to be philopatric, while male mammals are more likely to disperse.
What animals are polygyny?
