Climatic variation affects seasonal survival of an alpine bird species
Wildlife Biology, Volume 2025, Issue 4, July 2025.Mountains are particularly exposed to climate change, and empirical studies have shown that montane bird species are highly sensitive to the ongoing changes. Modelling mortality risks under climatic variation will give insight into species‐specific sensitivity. Willow ptarmigan Lagopus l.

DiversityStudying intraspecific differentiation in closely related species is essential to clarify the phylogenetic relationships and mechanisms of early stage speciation, particularly in evolutionarily young lineages affected by human-driven population declines.

No support for solar radiation as a major evolutionary driver of malar stripes in falcons
Journal of Avian Biology, Volume 2025, Issue 3, May 2025.The malar stripes of falcons (Falco spp.) are often hypothesised to function by reducing the amount of solar glare reflected into the falcon's eyes while hunting, thereby aiding foraging efficiency in bright conditions. This ‘solar glare hypothesis' is supported by intraspecific trends in peregrine falcons Falco peregrinus, in which populations ...

Conservation Science and Practice, Volume 7, Issue 4, April 2025.This article reviews the literature on how prairie dogs as keystone species affect grassland birds, an imperiled avian community. We tested hypotheses and synthesized conclusions from the literature, and then we identified key knowledge gaps to be filled with future work.

Regional demography of Icelandic rock ptarmigan and its implications for harvest management
Ecological Solutions and Evidence, Volume 5, Issue 4, October–December 2024.Integrated population models revealed regional differences in rock ptarmigan demography in Iceland. These differences warrant different harvest strategies, as demonstrated by both equilibrium and non‐equilibrium harvest strategies. Abstract The rock ptarmigan (Lagopus muta) is a popular game bird in Iceland, but management of hunting has tended to be ...
