Dynamic Soil Pressures Caused by Travelling Forest Machines
Croatian Journal of Forest Engineering, 2018 Machines travelling in forest stands cause dynamic loading of soil, the size of which depends on a multitude of factors such as terrain ruggedness, machine speed, axle load and tyre inflation pressure.

How to stay wild in a highly domesticated landscape? Spatiotemporal behaviour of wolves in Germany
Wildlife Biology, EarlyView.Wild animals can adapt to the increasing presence of humans by either becoming accustomed to it or by avoiding humans by spatiotemporal separation. The return of the wolf to the German lowlands raised the opportunity to study wolf behaviour in one of the most densely populated and fragmented countries in Europe, in an area where topography offers no ...

Causes of sprawl: A portrait from space [PDF]
We study the extent to which US urban development is sprawling and consider what determines differences in sprawl across space. Using remote-sensing data to track the evolution of land use on a grid of 8.7 billion 30x30 metre cells, we measure sprawl as ...

Wildlife Biology, EarlyView.Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Effects of Petroleum Development on Terrain Preferences of Calving Caribou
, 1996 We investigated terrain preferences of caribou (Rangifer tarandus granti) in an oilfield region near Prudhoe Bay, Alaska. Under disturbance-free conditions, the distribution of calving caribou determined by aerial transect surveys was correlated with ...

Wildlife Biology, EarlyView.Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

Spatiotemporal mapping the usable space of free‐roaming equids across the western United States
Wildlife Society Bulletin, EarlyView.Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Winter severity for white‐tailed deer in Alberta, Canada
Wildlife Society Bulletin, EarlyView.Abstract Winter Severity Indices (WSIs) are especially important for white‐tailed deer (Odocoileus virginianus), a species for which population dynamics often are tied to winter conditions throughout much of their range. However, existing WSIs often oversimplify environmental variability, limiting their ability to support effective management decisions.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system
CAAI Transactions on Intelligence Technology, EarlyView.Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.
