A Picky Predator and Its Prey: How Snow Conditions and Ptarmigan Abundance Impact Gyrfalcon Feeding Behaviour and Breeding Success [PDF]
Ecology and EvolutionSpecies interactions can be altered by climate change but can also mediate its effects. The gyrfalcon (Falco rusticolus) and the ptarmigan (Lagopus spp.) form a predator–prey couple that reflects the dynamics of boreal, tundra, and alpine ecosystems.

Genetic Passport System for Captive Falcons – Saker, Gyrfalcon and Peregrine Falcon Conservation Prospects in Russia. [PDF]
Пернатые хищники и их охрана, 2023 DNA analysis is a “gold standard” for individual identification and parentage studies as for humans, so for animals (Saks et al., 1991). First forensic testing of the rare animal species DNA occurred in 1991 in Great Britain, when the case of illegal ...

Serum protein electrophoresis reference values in the gyrfalcon (Falco rusticolus) [PDF]
Comparative Clinical Pathology, 2017 Blood samples were collected as part of routine clinical examination procedures from 120 clinically normal gyrfalcons (Falco rusticolus) during a 4-year period between the months of September and February. Serum protein electrophoresis (SPE) was carried out to establish reference values for the species and to characterize species-specific ...

Resident and Migratory Falcons' Breeding Phenology and Productivity Respond Differently to Weather and Climate Change Across the Arctic. [PDF]
Glob Chang BiolClimate change is altering breeding phenology and productivity of peregrine falcons and gyrfalcons across the circumpolar Arctic. Long‐term monitoring shows that responses vary among study areas and Arctic regions, with some populations advancing hatch dates while others show weaker or contrasting trends, highlighting spatially variable effects of ...
