Apparent Survival of Territorial Golden Eagles Using Non‐Invasive Genetic Profiling
In a novel study for the species, DNA was extracted from moulted feathers over 4 years involving 21% of the Scottish population of territorial golden eagles, and individuals' genetic profiles were analysed for apparent survival rates. Results showed sexual differences but not between two sub‐populations; very few cases of breeding dispersal were ...

Evaluating the demographic impacts of the highly pathogenic avian influenza panzootic
Our findings demonstrate that the HPAIV panzootic can cause rapid and long‐lasting impacts on the dynamics of long‐lived species. This raises major concerns for the conservation and long‐term viability of the many severely affected long‐lived species worldwide.

Our results demonstrate that to be effective in stimulating redistribution, an understanding of the drivers of site use is crucial for shooting‐based disturbance regimes. We emphasise the importance of providing refuges to encourage site use and highlight the importance of considering the spatio‐temporal coordination of shooting disturbance to ...

Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years
Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

Tracking the White-tailed Eagle Movements by Means of GPS/GSM-transmitters
During two and a half years we have tracked the movements of two different females of White-tailed Eagle (Haliaeetus albicilla). These birds demonstrate completely different movement patterns.

Red foxes that expand into tundra ecosystems threaten biodiversity, and knowledge on their space use is needed to inform management efforts. We found that red fox space use varied with seasons and with environmental contexts. Space use is likely affected by food densities linked to seasonality, human land use and the marine coastline.

Loggers affect the foraging behaviour and fitness of European shags
Biologgers enable real‐time collection of detailed behavioural and physiological data from wide‐ranging animals, including seabirds inhabiting remote regions. However, the number of studies using tracking devices has not been matched by research exploring the behavioural and fitness costs of deployment, and the effects on data reliability.
