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

Biological 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

The dual influence of top‐down and bottom‐up processes on a mesopredator and the consequences for prey

Ecography, EarlyView.
Ecosystem dynamics are shaped by interacting top‐down and bottom‐up processes, yet their relative importance may vary through time following disturbances such as disease outbreaks and changes in apex predator communities. Using a 52‐year time series in south‐central Sweden, we examined how disease, apex predators, and prey availability jointly impact a
