The Influence of Aspen Chemistry and the Nutritional Context on Aspen Herbivory
, 2017 Herbivory is one major force accelerating aspen decline in North America, but it is unclear why herbivores prefer certain aspen stands over others, or over other plant species in the understory. In this dissertation, I determined the influence of nutrients and plant secondary compounds (PSC), physiological state, chemical composition, and prior ...

Veterinary Record, EarlyView.Abstract Background Research into disorders in captive reptiles is notably sparse in the UK, despite the popularity of various species as pets. This study aimed to survey and investigate risk factors for disorders of leopard geckos in the UK. Methods Medical records for leopard geckos presenting at three veterinary practices between 2019 and 2023 were ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects
Wildlife Biology, EarlyView.Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Dendroecological Research into Aspen Growth in the Conditions of the Moscow Region
Лесной журналAccording to V.A. Dragavtsev's concept, the reaction of the annual ring to the provocative environmental background of different years creates a “portrait” of adaptive polygenic genotype systems.

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Micro‐habitat selection by boreal woodland caribou improves access to food
Wildlife Biology, EarlyView.Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR
Wildlife Biology, EarlyView.Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.
