Data from: Natal and breeding philopatry of female Steller sea lions in southeastern Alaska

, 2017
Information on drivers of dispersal is critical for wildlife conservation but is rare for long-lived marine mammal species with large geographic ranges.

Assessing the role of ontogenetic movement in maintaining population structure in fish using otolith microchemistry

Ecology and Evolution, 2018
Identifying the mechanisms maintaining population structure in marine fish species with more than a single dispersing life stage is challenging because of the difficulty in tracking all life stages.

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit (Parus major) territories across Europe

Journal of Animal Ecology, EarlyView.
Across six European cities, great tits in more impervious territories had paler carotenoid‐based plumage, but not lower brightness or UV chroma. This suggests that urban habitat imperviousness is associated specifically with lower carotenoid pigment deposition, rather than broad changes in feather reflectance or structural quality.

Fine-scale site fidelity in California sea lions, Zalophus californianus, in the colony at Los Islotes, La Paz Bay, Mexico

Ciencias Marinas, 2019
Fine-scale site fidelity in polygynous pinnipeds influences individual interactions, social stability, and gene flow; over time, demographic processes may be altered, and local extinction of some colonies may occur.

Stabilization and optimization of host-microbe-environment interactions as a potential reason for the behavior of natal philopatry

Animal Microbiome, 2021
Many animals engage in a behavior known as natal philopatry, where after sexual maturity they return to their own birthplaces for subsequent reproduction.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

Integrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Philopatry and Dispersal Patterns in Tiger (Panthera tigris)

PLoS ONE, 2013
Tiger populations are dwindling rapidly making it increasingly difficult to study their dispersal and mating behaviour in the wild, more so tiger being a secretive and solitary carnivore.We used non-invasively obtained genetic data to establish the presence of 28 tigers, 22 females and 6 males, within the core area of Pench tiger reserve, Madhya ...

Reproductive Biology, Mating System, and Extended Natal Association in the Echolocating Dalou Mountains Tree Mouse (Typhlomys daloushanensis): Insights Into Sensory Adaptation and Life‐History Strategy

Integrative Zoology, EarlyView.
Typhlomys daloushanensis, a poorly known and unique echolocating rodent. Using a captive breeding colony, we quantify key reproductive parameters, including gestation length, litter size, interbirth interval, and development to maturity, and evaluate these in relation to mating system structure.

Data from: Two decades of genetic profiling yields first evidence of natal philopatry and long-term fidelity to parturition sites in sharks

, 2013
Sharks are a globally threatened group of marine fishes that often breed in their natal region of origin. There has even been speculation that female sharks return to their exact birthplace to breed (“natal philopatry”), which would have important ...

Urban Environments Impact Parasite Diversity and an Antipredator Response in an Amphibian Model

Integrative Zoology, EarlyView.
Urbanization reshapes parasite–host interactions in the amphibian Pelophylax perezi, increasing blood parasite diversity and Lankesterella loads under higher anthropogenic pressure. Urban frogs also show longer flight initiation distances and tibiofibulae, indicating altered antipredator strategies.
