The distribution of priority units on (A) HDI, (B) elevation, and (C) TRI zones.

, 2014
The numbers 1 to 7 on the horizontal axes represent (A) low to high HDI value classifications, (B) elevation zones of 4,000 m, and (C) terrain categories of level, near-level, slightly-rugged, intermediately-rugged, moderately-rugged, highly-rugged, and ...

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.

Exploring the Effects of Topography on Leaf Area Index Retrieved from Remote Sensing Data at Various Spatial Scales over Rugged Terrains

Remote Sensing
Topography significantly affects remotely sensed reflectance data and subsequently impacts the retrieval of the leaf area index (LAI) from surface reflectance data over rugged terrains.

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

Journal of Animal Ecology, EarlyView.
Using a spatially explicit model parameterized with GPS telemetry, we show that migratory and resident red deer play distinct roles in nitrogen redistribution across alpine landscapes. Migrants uniquely transport nitrogen upslope and up elevation, linking ecosystem element pools and revealing how the loss of migration alters large‐scale ecosystem ...

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

The estimation of errors in calculated terrain corrections in the Tatra Mountains

Contributions to Geophysics and Geodesy, 2010
In general, calculation of terrain corrections can be a substantial source of errors in evaluating Bouguer anomalies, especially in rugged mountainous areas like the Tatra Mountains where we also get the largest values of the terrain corrections as such.

Burned habitats facilitate predation and lead to long‐term reductions in prey success

Journal of Animal Ecology, EarlyView.
By evaluating the effects of burned habitats on the habitat selection and movement responses of cougars and mule deer, cougar kill sites, and mule deer reproduction, the authors find that increasingly large, severe burns are diminishing herbivore reproductive success, potentially due to advantages for predators created by burned landscapes.
