Ecological bases of philopatry and cooperation in Ethiopian wolves
, 2012 Ecological reasons for philopatry and cooperation are frequently invoked when kin selection is an insufficient explanation. The Ethiopian wolf (Canis simensis) is a specialised rodent hunter that forms family groups with cooperative breeding but also ...

Philopatry in prairie voles: an evaluation of the habitat saturation hypothesis
, 2009 Natal philopatry, or delayed dispersal of sexually mature offspring, may be due to ecological constraints on dispersal. In this study, we manipulated the population density of prairie voles (Microtus ochrogaster) living in experimental outdoor enclosures

Spacing Patterns, Mating systems, and winter Philopatry in Harlequin ducks. [PDF]
, 2000 Many species of waterfowl form pair bonds during the nonbreeding season, yet current descriptions of mating systems and patterns of philopatry in waterfowl focus on the breeding grounds. We studied wintering Harlequin Ducks (Histrionicus histrionicus) in

First Record of Female Philopatry in the Tribe Centridini (Hymenoptera: Apidae)
SociobiologyThis study addresses the behavior and ecology of the solitary bee Centris aenea. The objective was to verify the philopatry of this bee’s females. The study was carried out in a nest aggregation in the Restinga area in Coroa Vermelha, Santa Cruz de ...

Breeding dispersal by Ross’s geese in the Queen Maud Gulf metapopulation [PDF]
Animal Biodiversity and Conservation, 2004 We estimated rates of breeding philopatry and complementary dispersal within the Queen Maud Gulf metapopulation of Ross’s Geese (Chen rossii) using multistate modeling of neckband observations at five breeding colonies, 1999–2003.

Demographic components of philopatry and nest-site fidelity of Pacific black brant [PDF]
, 1996 Dissertation (Ph.D.) University of Alaska Fairbanks, 1996I investigated demographic components of nest-site fidelity and philopatry of Pacific black brant (Branta bernicla nigricans).

Selection and sex-biased dispersal: the influence of philopatry on adaptive variation
, 2015 Sex-biased dispersal is expected to homogenize nuclear genetic variation relative to variation in genetic material inherited through the philopatric sex. When site fidelity occurs across a heterogeneous environment, local selective regimes may alter this

Molecular genetic diversity in populations of the stingless bee Plebeia remota: A case study
Genetics and Molecular Biology, 2013 Genetic diversity is a major component of the biological diversity of an ecosystem. The survival of a population may be seriously threatened if its genetic diversity values are low.
