Age-Dependent Dispersal and Relatedness in Tiger Sharks (Galeocerdo cuvier)

open access: yesFrontiers in Marine Science, 2022
Understanding dispersal in large marine fauna is necessary for conservation, but movement patterns often vary widely by sex and life stage. In sharks, genetic studies have shown evidence of widespread male-biased dispersal, though tagging and tracking ...

Whale sharks of the western Caribbean: an overview of current research and cnservation efforts and future needs for effective management of the species [PDF]

open access: yes, 2007
Whale sharks (Rhincodon typus) are seasonal visitors to four sites in the Western Caribbean, 3 of which are encompassed by the Mesoamerican Barrier Reef.

Strategic nest site selection in one of the world's largest loggerhead turtle nesting colonies, on Maio Island, Cabo Verde

open access: yesOryx, 2023
For species without parental care, such as sea turtles, nest site selection is particularly important for embryo development, hatchling survival and, ultimately, reproductive success. We conducted an 8-year (2012–2019) capture–mark–recapture study of the

Winter Philopatry in Migratory Waterfowl [PDF]

open access: yesThe 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 ...

Telemetry and genetics reveal asymmetric dispersal of a lake‐feeding salmonid between inflow and outflow spawning streams at a microgeographic scale

open access: yesEcology and Evolution, 2020
The degree of natal philopatry relative to natal dispersal in animal populations has important demographic and genetic consequences and often varies substantially within species.

No leading‐edge effect in North Atlantic harbor porpoises: Evolutionary and conservation implications

open access: yesEvolutionary Applications, 2021
Understanding species responses to past environmental changes can help forecast how they will cope with ongoing climate changes. Harbor porpoises are widely distributed in the North Atlantic and were deeply impacted by the Pleistocene changes with the ...

Host-pathogen evolutionary signatures reveal dynamics and future invasions of vampire bat rabies [PDF]

open access: yes, 2016
Anticipating how epidemics will spread across landscapes requires understanding host dispersal events that are notoriously difficult to measure. Here, we contrast host and virus genetic signatures to resolve the spatiotemporal dynamics underlying ...

The Cognitive Ecology of Animal Movement: Evidence From Birds and Mammals

open access: yesFrontiers 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 ...

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]

open access: yes, 2012
Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

Female philopatry and dominance patterns in wild geladas [PDF]

open access: yesAmerican Journal of Primatology, 2010
AbstractCercopithecines have a highly conserved social structure with strong female bonds and stable, maternally inherited linear dominance hierarchies. This system has been ascribed to the pervasiveness of female philopatry within the typical multi‐male, multi‐female social groups.
