Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Isolating Mechanisms in Seabirds [PDF]
In most species of birds, differences in plumage coloration or song structure act as isolating mechanisms. In seabirds, plumages are generally drab, and vocal repertoires are limited so that other phenotypic attributes must act as isolating mechanisms.

Accounting for animal movement during aerial imaging surveys
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 ...

The eradication of rats (Rattus norvegicus, R. exulans and R. rattus) on islands is essential for the preservation of island ecosystems, including seabird populations, which are particularly vulnerable to rat predation.

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.

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 ...

Den attendance by Arctic foxes experiencing 10 years of increasing tourism
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
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

Bio‐logging has revealed much about high‐latitude seabird migratory strategies, but migratory behaviour in tropical species may differ, with implications for understanding nutrient deposition.

Using programmable infusion pump in avian species – a validation methodology in geese
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.
