Foxtrot migration and dynamic over-wintering range of an Arctic raptor [PDF]

eLife, 2023
Advances in tracking technologies have revealed the diverse migration patterns of birds, which are critical for range mapping and population estimation.

Arctic Migratory Raptor Selects Nesting Area During the Previous Breeding Season

Frontiers in Ecology and Evolution, 2022
Migratory species have a limited time for habitat selection upon arrival at the breeding grounds. This is especially evident in arctic migrants, which are restricted by a narrow window of opportunity when environmental conditions are favorable for ...

Multi-scale selection models predict breeding habitat for two Arctic-breeding raptor species

Arctic Science, 2020
Raptors are important environmental indicators because they are apex predators and can be sensitive to disturbance. Few studies have addressed habitat preferences of tundra-nesting raptors, and those that exist have focused on fine-scale characteristics.

Evolution and Climate Adaptation in Eurasian Gyrfalcon Populations [PDF]

Ecology and Evolution
Climate change is considered a key driver for shaping ecological and evolutionary processes of Arctic animals. Historical glaciation has profoundly influenced the distribution and genetic differentiation of Arctic vertebrates, and recently Arctic species

Vulnerability to geomorphological hazards of an Arctic cliff-nesting raptor, the rough-legged hawk

Arctic Science, 2017
Increase in temperature and precipitation associated with climate change may enhance the risk of destruction by geomorphological processes of nests or dens used by Arctic wildlife.

Arctic introgression and chromatin regulation facilitated rapid Qinghai-Tibet Plateau colonization by an avian predator [PDF]

Nature Communications, 2022
The Qinghai-Tibet Plateau is as cold as the Arctic, but presents unique hypoxia and high ultraviolet conditions. Here the authors find that gene flow from Arctic gyrfalcons aids plateau saker falcons’ cold adaptation, and independent non-coding genomic ...

Isotopic niche partitioning and individual specialization in an Arctic raptor guild [PDF]

Oecologia, 2021
Abstract Intra- and inter-specific resource partitioning within predator communities is a fundamental component of trophic ecology, and one proposed mechanism for how populations partition resources is through individual niche variation. The Niche Variation Hypothesis (NVH) predicts that interindividual trait variation leads to functional trade-

Assessing the causes of breeding failure among the rough-legged buzzard (Buteo lagopus) during the nestling period [PDF]

Polar Research, 2012
When food becomes scarce, the youngest nestlings in facultatively siblicidal raptor species typically die and such events are usually attributed to siblicide.

Network topology of stable isotope interactions in a sub-arctic raptor guild [PDF]

Oecologia, 2016
Predation is an ecologically important process, and intra-guild interactions may substantially influence the ecological effects of predator species. Despite a rapid expansion in the use of mathematical graph theory to describe trophic relations, network approaches have rarely been used to study interactions within predator assemblages.
