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

The gyrfalcon (Falco rusticolus) genome [PDF]

G3: Genes, Genomes, Genetics, 2023
High-quality genome assemblies are characterized by high-sequence contiguity, completeness, and a low error rate, thus providing the basis for a wide array of studies focusing on natural species ecology, conservation, evolution, and population genomics ...

Resident and Migratory Falcons' Breeding Phenology and Productivity Respond Differently to Weather and Climate Change Across the Arctic. [PDF]

Glob Chang Biol
Climate 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 ...

Phylogenomic insights into the polyphyletic nature of Altai falcons within eastern sakers (Falco cherrug) and the origins of gyrfalcons (Falco rusticolus) [PDF]

Scientific Reports, 2023
The Altai falcon from Central Asia always attracted the attention of humans. Long considered a totemic bird in its native area, modern falconers still much appreciated this large-bodied and mighty bird of prey due to its rarity and unique look.

A Picky Predator and Its Prey: How Snow Conditions and Ptarmigan Abundance Impact Gyrfalcon Feeding Behaviour and Breeding Success [PDF]

Ecology and Evolution
Species 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.

Survival rates of adult and juvenile gyrfalcons in Iceland: estimates and drivers [PDF]

PeerJ, 2021
Knowledge of survival rates and their potential covariation with environmental drivers, for both adults and juveniles, is paramount to forecast the population dynamics of long-lived animals.

A Monoclonal Antibody ELISA-Based Assay for Measuring the Potency of Candidate H5 Clade 2.3.4.4b Pandemic Influenza Vaccines. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background The single radial immunodiffusion (SRID) assay is used to determine the potency of inactivated influenza vaccines. Nevertheless, development of alternative influenza vaccine potency assays with greater sensitivity and less reliance on large quantities of reference reagents is needed.

Gyrfalcon Prey Abundance and Their Habitat Associations in a Changing Arctic [PDF]

Ecology and Evolution
Arctic habitats are changing rapidly and altering trophic webs and ecosystem functioning. Understanding how species' abundances and distributions differ among Arctic habitats is important in predicting future species shifts and trophic‐web consequences ...

Chromosome-level reference genome assembly of the gyrfalcon (Falco rusticolus) and population genomics offer insights into the falcon population in Mongolia [PDF]

Scientific Reports
The taxonomic classification of a falcon population found in the Mongolian Altai region in Asia has been heavily debated for two centuries and previous studies have been inconclusive, hindering a more informed conservation approach.

Home Range and Habitat Selection of the Endangered Red Goshawk (<i>Erythrotriorchis radiatus</i>) Across Australia's Tropical Savannas. [PDF]

Ecol Evol
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.
