Abundance and occupancy trends of sooty grouse in western Oregon: determining best modeling practices by comparing observed and simulated data

Wildlife Biology, EarlyView.
Sooty grouse Dendragapus fuliginosus are large game birds that occupy montane forests in the Pacific Northwest, USA. These forests have been altered by human activities, which have been shown to have both positive and negative impacts on local populations.

Passive acoustic monitoring with AI‐based detection and identification reveal sooty grouse hooting patterns in western Oregon

Wildlife Biology, EarlyView.
Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Drought and growing season phenology over 35 years modulates species interactions among domestic and wild herbivores

Journal of Animal Ecology, EarlyView.
Using a unique 35‐year dataset, this study shows that domestic livestock do not facilitate wild large herbivores as predicted by the grazing optimization hypothesis. Instead, competition caused avoidance of cattle by elk which intensified under drought, and highlights how climate change influences interactions among domestic and wild large herbivores ...

Effect of site and provenance on the length of transfusion parenchyma of Douglas-fir needles [PDF]

Glasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2019
Douglas-fir has been the most common introduced conifer species in European plantations since 1825. The analysis of the characteristics of the introduced tree species by conducting genetic tests may predict the success of transfer of Douglas-fir
