Helminth gut parasites of black grouse Lyrurus tetrix in northern England, their impact on productivity and possible sources of infection

Wildlife Biology, EarlyView.
Black grouse Lyrurus tetrix declines continue throughout much of temperate Europe, following habitat loss and population isolation, associated with reduced productivity. In northern England, only 1437 lekking males remained in 2014, genetically isolated from other UK populations, and typified by low productivity but high adult survival.

Fecal corticosterone metabolite levels in two closely related rodent species in a sub‐Mediterranean environment

Wildlife Biology, EarlyView.
Glucocorticoids regulate many physiological functions and play an important role in coping with challenging stimuli. The non‐invasive assessment of glucocorticoids is increasingly used as a tool to evaluate individual and population health status in wild animals.

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

Wildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Movements of Juvenile Hen Harriers (Circus cyaneus) Tracked by Satellite Telemetry in Spain

Birds
The Hen Harrier (Circus cyaneus) is a medium-sized raptor with a broad distribution across the Palearctic. In Spain, Hen Harrier behaviour is diverse due to being at the southern limit of its distribution, and the margins of distributions tend to show ...

MNK Controls mTORC1:Substrate Association through Regulation of TELO2 Binding with mTORC1

Cell Reports, 2017
The mechanistic target of rapamycin (mTOR) integrates numerous stimuli and coordinates the adaptive response of many cellular processes. To accomplish this, mTOR associates with distinct co-factors that determine its signaling output. While many of these

Comparing manual and automated methods for identifying individual great gray owls via territorial calls

Wildlife Society Bulletin, EarlyView.
We compared 2 audio analysis methods: 1) manual spectral analysis, and 2) automated mel‐frequency cepstral coefficients (MFCCs), to identify great gray owls (Strix nebulosa) to individual using territorial calls. The MFCC method was 97.6% accurate at classifying individuals whereas spectral analysis had only a 77.2% accuracy rate.

Resource suitability drives low use of avian‐excavated tree cavities: A multi‐state occupancy dynamics approach

Journal of Animal Ecology, EarlyView.
Birds that nest in tree cavities are sometimes dependent on a few cavity‐excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because excavated cavities may be unsuitable for continued use, even when available for several years after excavation.
