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

open access: yesWildlife 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 ...

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

open access: yesWildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

New to town: home range size, habitat selection and behavioral adaptations by urban hares

open access: yesWildlife Biology, EarlyView.
European hares Lepus europaeus have recently been shown to colonize urban areas in different parts of Europe. This appears to be a novel phenomenon, and little is known about the space use and behavioral adaptations of hares living in urban areas. Here, we describe the first findings concerning home range sizes from GPS‐collared hares (n = 3) in Aarhus

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 ...

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

open access: yesWildlife 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

open access: yesWildlife 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

Overdispersion in service systems

open access: yes, 2020
In this thesis service systems with nonstandard arrival processes are studied. In order to mimic real arrival data, we choose to incorporate overdispersion in the models. This feature is abundantly present in (arrival) data of e.g., emergency departments and call centers and corresponds to the phenomenon that the variance of the number of arrivals is ...

Regional coyote densities estimated from camera trapping covary with deer productivity, anthropogenic land use, and human–coyote conflicts

open access: yesWildlife Biology, EarlyView.
Density estimates assist conservation and management decisions. Unfortunately, management of elusive mesocarnivores occurring at low densities has often relied on qualitative metrics or population indices. The proliferation of camera trap sampling of wildlife provides an opportunity to apply recently developed methods for estimating density of unmarked
