Why wolves walk – drivers of daily movement in a social large carnivore

Wildlife Biology, EarlyView.
Animal movement patterns are influenced by a range of extrinsic and intrinsic factors, including the distribution of resources, human disturbance, landscape connectivity, species interactions, and individual traits. We examined factors associated with daily movement distance (DMD) and linearity in 20 territorial Scandinavian wolves Canis lupus during ...

Motion planning of a robotic arm on a wheeled vehicle on a rugged terrain [PDF]

, 1996
This paper presents a set of motion planners for an exploration vehicle on a simulated rugged terrain. The vehicle has four wheels for its movement and a robotic arm mounted on the vehicle for object manipulation.

Detecting changes in distribution and abundance using harvest data in two sympatric bear species in Southeast Alaska

Wildlife Biology, EarlyView.
Monitoring wildlife populations in remote landscapes is challenging due to the difficulties of conducting field surveys. However, harvest data, which are routinely collected by management agencies, offer valuable insights into population trends. Brown bear Ursus arctosand American black bear U.

Prioritizing areas for wolf management in Austria by modelling potential habitat and depredation risk

Wildlife Biology, EarlyView.
The recovery of wolf populations across Europe has reignited human–wildlife conflicts, particularly in countries such as Austria, where wolves have been absent for more than a century. Livestock depredation remains one of the primary sources of tension, and effective management requires a solid spatial basis for planning.

SGOT: A Simplified Geometric-Optical Model for Crown Scene Components Modeling over Rugged Terrain

, 2022
Topography affects the fraction of scene components of the canopy and background, resulting in the observed reflectance distortion. Modeling the canopy reflectance over rugged terrain needs to account for topographic effects.

Fine‐scale spatio‐temporal niche partitioning enables coexistence of wild ungulates and livestock in a resource‐limited Himalayan landscape, India

Wildlife Biology, EarlyView.
Understanding how wild ungulates share space with domestic livestock is central to conservation planning in Himalayan multi‐use landscapes. This study focuses on multi‐axis niche relationships among six wild ungulates: hangul Cervus hanglu hanglu, Kashmir musk deer Moschus cupreus, Himalayan goral Naemorhedus goral, kashmir markhor Capra falconeri ...

A Stepwise BRDF-Based Land Surface Reflectance Model Over Rugged Terrain

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The land surface reflectance is an essential variable of remote sensing, which is significantly affected by topography and atmosphere. Rugged terrain significantly alters the radiative transfer among the solar-terrain-sensor, resulting in large errors in

Forest and fire drive moose (deníe) detections near their northern range limit

Wildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...
