Feeding Hotspots and Distribution of Fin and Humpback Whales in the Norwegian Sea From 2013 to 2018

open access: yesFrontiers in Marine Science, 2021
Fin whales (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) are commonly found in the Norwegian Sea during the summer months. Records from around 1995 to 2004 show that their distribution patterns were mainly associated with those of ...

Influence of age and sex on winter site fidelity of sanderlings Calidris alba [PDF]

open access: yesPeerJ, 2016
Many migratory bird species show high levels of site fidelity to their wintering sites, which confers advantages due to prior knowledge, but may also limit the ability of the individual to move away from degrading sites or to detect alternative foraging ...

Interaction between dietary and habitat niche breadth influences cetacean vulnerability to environmental disturbance

open access: yesEcosphere, 2021
Ecosystems are experiencing elevated levels of disturbance, and species with narrower niches are often more vulnerable to disturbances. Niche breadth is often measured in terms of either diet or habitat use but diet and spatial use are infrequently ...

Large‐scale movement patterns in a social vulture are influenced by seasonality, sex, and breeding region

open access: yesEcology and Evolution, 2023
Quantifying space use and segregation, as well as the extrinsic and intrinsic factors affecting them, is crucial to increase our knowledge of species‐specific movement ecology and to design effective management and conservation measures.

The Influence of Intrinsic Factors and Release Trials on Site Fidelity and Dispersal of Reintroduced Golden Parakeets (Guaruba guarouba, Aves, Psittacidae)

open access: yesDiversity
Reintroducing threatened fauna has been established as a valuable conservation practice despite the obstacles that such projects still face. In avian reintroductions, elevated dispersal of released individuals is one of the main factors preventing the ...

Identifying spawning sites and fidelity of Ogaa (Walleye, Sander Vitreus): implications for fishery stewardship

open access: yesFrontiers in Fish Science
Many giigoonyag (fishes) species worldwide display spawning site fidelity, making them especially susceptible to habitat disturbances in spawning areas.

Interannual breeding site fidelity in eastern wild turkey flocks

open access: yesWildlife Society Bulletin
Understanding space use during key life‐history periods is critical to understanding demographic outcomes of most species. For gregarious species, similar space is often shared by individuals and across generations during these key periods.

Long‐Term Demographic Trends of Near Threatened Coastal Dolphins Living in an Urban Estuary

open access: yesEcology and Evolution
Understanding population demography of threatened species and how they vary in relation to natural and anthropogenic stressors is essential for effective conservation. We used a long‐term photographic capture‐recapture dataset (1993–2020) of Indo‐Pacific
