Female site fidelity of the Mealy Mountain caribou herd (Rangifer tarandus caribou) in Labrador
Rangifer, 2011 The Mealy Mountain caribou population of southeastern Labrador is listed as threatened. Site fidelity - the philopatric tendency of an animal to remain in or return to the same site - has often been suspected in sedentary caribou like the Mealy Mountain,

Polar Research, 2021 Philopatry influences animal distribution and can lead to a kinship-based spatial structure, where proximity and relatedness are tightly linked. In the Barents Sea region, polar bears (Ursus maritimus) of the coastal ecotype remain year-round within the ...

Philopatry and migration of Pacific white sharks [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2009 Advances in electronic tagging and genetic research are making it possible to discern population structure for pelagic marine predators once thought to be panmictic. However, reconciling migration patterns and gene flow to define the resolution of discrete population management units remains a major challenge, and a vital conservation priority for ...

Diverse demographic factors influence apparent juvenile survival in a migratory songbird
Ecosphere, 2021 To better understand the dynamics of avian populations and their role in population trends, we require an in‐depth understanding of the factors influencing the survival of adults and juveniles.

Ecology and Evolution, 2021 Seabirds, particularly Procellariiformes, are highly mobile organisms with a great capacity for long dispersal, though simultaneously showing high philopatry, two conflicting life‐history traits that may lead to contrasted patterns of genetic population ...

Unsustainable anthropogenic mortality disrupts natal dispersal and promotes inbreeding in leopards
Ecology and Evolution, 2020 Anthropogenic mortality of wildlife is typically inferred from measures of the absolute decline in population numbers. However, increasing evidence suggests that indirect demographic effects including changes to the age, sex, and social structure of ...

Winter Philopatry in Migratory Waterfowl [PDF]
The Auk, 1999 Philopatry in migratory species can apply to any location used during the annual cycle. The degree of philopatry influences the genetic structure of populations, but only at the stage of the annual cycle when pair formation and gene exchange occur. Because pair formation in birds typically occurs during the breeding season, most studies have fo- cused ...

The Cognitive Ecology of Animal Movement: Evidence From Birds and Mammals
Frontiers in Ecology and Evolution, 2021 Cognition, defined as the processes concerned with the acquisition, retention and use of information, underlies animals’ abilities to navigate their local surroundings, embark on long-distance seasonal migrations, and socially learn information relevant ...
