The seabird wreck in the Bay of Biscay and South-Western Approaches in 2014: A review of reported mortality [PDF]

open access: yes, 2016
Between December 2013 and February 2014, a series of storm events occurred in areas of the North Atlantic frequented by migratory seabirds. Prolonged exposure to sustained storm conditions was followed by an unprecedented level of seabird mortality ...

Seabirds as a subsistence and cultural resource in two remote Alaskan communities

open access: yesEcology and Society, 2014
Small rural Alaskan communities face many challenges surrounding rapid social and ecological change. The role of local subsistence resources may change over time because of changes in social perception, economic need, and cultural patterns of use.

Accounting for animal movement during aerial imaging surveys

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

Changes in the distribution of nesting Arctic seaducks are not strongly related to variation in polar bear presence

open access: yesArctic Science, 2020
Contemporary climate change is predicted to expose some species to altered predation regimes. Losses of Arctic sea ice are causing polar bears to increasingly forage on colonial seaduck eggs in lieu of ice-based hunting of marine mammals.

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

From Map Follower to Navigator: Archetypes of Environmental Impact Assessment

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Environmental impact assessment (EIA) scholarship is commonly framed as a tension between efficiency and comprehensiveness paradigms. These paradigms describe a persistent tension but cannot explain how EIA operates through it. Drawing on social systems theory, this analysis traces that operation.

Study of the Nasal Cavity of the Cadaveric Yellow-Legged Gull (Larus michahellis atlantis) Through Anatomical Cross-Sections and Computed Tomography

open access: yesAnimals
Understanding the anatomy of the avian nasal cavity and paranasal sinuses is essential for diagnosing respiratory diseases and interpreting imaging findings. However, detailed tomographic descriptions of these structures are scarce in seabirds.

Den attendance by Arctic foxes experiencing 10 years of increasing tourism

open access: yesWildlife Biology, EarlyView.
Wildlife tourism is a growing industry, and an increasing number of people seek to observe and interact with wild animals in their natural surroundings. In Iceland, the native Arctic fox Vulpes lagopus is widespread and has been under heavy hunting pressure for centuries.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems

open access: yesWildlife Biology, EarlyView.
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,
