Habitat selection and potential fitness consequences of two early‐successional species with differing life‐history strategies

open access: yesEcology and Evolution, 2019
Habitat selection and its relationship to fitness is a fundamental concept in ecology, but the mechanisms driving this connection are complex and difficult to detect.

Evaluating the efficacy of carbachol at reducing corvid predation on artificial nests

open access: yesWildlife Society Bulletin, 2018
Nest predation often limits recovery of threatened and endangered birds, especially ground‐nesting species. Accordingly, a variety of techniques are used to reduce the impact of nest predation on listed species.

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
