Winter philopatry in migratory waterfowl,1999.

, 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 ...

Pliocene Origin, Ice Ages and Postglacial Population Expansion Have Influenced a Panmictic Phylogeography of the European Bee-Eater Merops apiaster

Diversity, 2019
Oscillations of periods with low and high temperatures during the Quaternary in the northern hemisphere have influenced the genetic composition of birds of the Palearctic.

Application of close‐kin mark–recapture to an American black bear population using harvest samples

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract Close‐kin mark–recapture (CKMR) offers a promising alternative to traditional mark–recapture methods for estimating wildlife population parameters. CKMR estimates demographic parameters by identifying genetic relationships between individuals, effectively “recapturing” parental genotypes through their offspring's genetic profiles.

Sea Turtle Nesting Beach Fidelity Revealed by Satellite Tracking

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our study demonstrates mixed fidelity strategies within an island hawksbill population, suggesting that fidelity reflects natal philopatry and the proximity of alternative sites. Limited monitoring coverage at remote sites likely contributes to under‐detection of nestings by study‐beach unfaithful individuals. Individuals using alternative sites signal

Agricultural Landscapes and Forest Fragments Shape Population Dynamics, Cuticular Lipids and the Conservation of the Masked Bees, Hylaeus communis

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Small size solitary bees are often neglected. We successfully sample tiny masked bees with trap nests. We found population living in conventional farm lands are under risk compared to organic farm lands.ABSTRACTOrganic farming has been shown to offer advantages over conventional farming in protecting insect biodiversity, but our overall understanding ...

Habitat selection and site fidelity on winter home ranges of Eastern Whip-poor-wills (Antrostomus vociferus)

Avian Conservation and Ecology, 2022
The Eastern Whip-poor-will (Antrostomus vociferus), an aerial insectivore experiencing population declines, was recently upgraded from Least Concern to Near Threatened status by the International Union for Conservation of Nature (IUCN), highlighting ...

Use of genetic mark-recapture to estimate breeding site fidelity and philopatry in a threatened sea duck population, Alaska-breeding Steller’s eiders

Endangered Species Research, 2020
The Steller’s eider Polysticta stelleri is a sea duck that breeds in Arctic tundra regions of Russia and Alaska (USA). The Alaska-breeding population is listed as ‘threatened’ under the US Endangered Species Act because of a perceived contraction of the ...

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Molecular relatedness-based analyses reveal breeding site philopatry in female bluntnose sixgill sharks (Hexanchus griseus)

Frontiers in Marine Science
The bluntnose sixgill shark (Hexanchus griseus) is a deep-water, globally distributed, but data-limited species due to its habitat use and cryptic nature.
