Ungulate substrate use in fauna passages

open access: yesWildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Micro‐habitat selection by boreal woodland caribou improves access to food

open access: yesWildlife 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 ...

The intrinsic rate of increase of reindeer and caribou populations in arctic environments

open access: yesRangifer, 1990
The intrinsic rate of increase of an animal population, rm, is specific to the environment in which it is measured. Previous estimates of maximum growth rates for reindeer and caribou Rangifer tarandus populations were based on introductions to islands ...

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

open access: yesWildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Reindeer and caribou (Rangifer tarandus) response towards human activities

open access: yesRangifer, 2009
We address the question of how human activities and infrastructure influence reindeer/caribou’s (Rangifer tarandus) behaviour and habitat use and review studies based on current methodologies.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Modeling Regional Dynamics of Human-Rangifer Systems: a Framework for Comparative Analysis

open access: yesEcology and Society, 2013
Theoretical models of interaction between wild and domestic reindeer (Rangifer tarandus; caribou in North America) can help explain observed social-ecological dynamics of arctic hunting and husbandry systems.

To stay or to roam? Behavioural type influences trade‐offs in male wild turkey survival

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals develop familiarity with specific areas through repeated use, gaining detailed knowledge of local conditions, such as food availability, predator presence, and landscape features, which can directly impact fitness.
