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

Wildlife 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 ...

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Born to die: pack and population level estimates of wolf pup survival and recruitment in the Greater Voyageurs Ecosystem

Wildlife Biology, EarlyView.
Wolf pup Canis lupus survival is a key driver of wolf population dynamics that remains poorly understood, especially in forested systems, because wolf pups are difficult to monitor. We used a combination of pup counts at dens and remote camera observations to estimate annual survival and recruitment of wolf pups in the Greater Voyageurs Ecosystem, MN ...

A dog makes a difference: exploration of potential biases in moose‐hunting associated citizen science

Wildlife Biology, EarlyView.
The collection of citizen data is often employed to generate insights regarding species distribution, population sizes, and population structure; however, biases inherent in citizen science are seldom addressed. In this study, we examined the factors influencing hunters' observations of moose, Alces alces, during the moose hunting season in Finland. By

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

Wildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...
