Leopard (Panthera pardus) occupancy in the Chure range of Nepal

Ecology and Evolution, 2021
Conservation of large carnivores such as leopards requires large and interconnected habitats. Despite the wide geographic range of the leopard globally, only 17% of their habitat is within protected areas.

Improving Accuracy in Earthwork Volume Estimation for Proposed Forest Roads Using a High-Resolution Digital Elevation Model

Croatian Journal of Forest Engineering, 2012
Earthwork usually represents the largest cost component in the construction of low-volume forest roads. Accurate estimates of earthwork volume are essential to forecast construction costs and improve the financial control of road construction operations.

Spatiotemporal patterns of elephant and chimpanzee occurrence amid hunting in an unprotected African rainforest

Conservation Science and Practice
Anthropogenic pressures are driving major declines in mammals, especially in unprotected areas. However, our understanding of how mammals coexist with humans and adapt to hunting in human‐dominated landscapes remains limited. Here, we used long‐term data

Geometric approaches to computing 3D-landscape metrics

Landscape Online, 2010
The relationships between patterns and processes lie at the core of modern landscape ecology. These dependences can be quantified by using indices related to the patch-corridor-matrix model.

Analysis of the Ducted Gravity Waves Generated by Elevated Convection over Complex Terrain in China

Atmosphere
Gravity waves play a crucial role in the evolution of convective systems. The unique thermal structure of elevated convection occurring above a stable boundary layer facilitates the generation and propagation of gravity waves.

DIGITAL ELEVATION MODEL CORRECTION IN URBAN AREAS USING EXTREME GRADIENT BOOSTING, LAND COVER AND TERRAIN PARAMETERS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The accuracy of digital elevation models (DEMs) in urban areas is influenced by numerous factors including land cover and terrain irregularities. Moreover, building artefacts in global DEMs cause artificial blocking of surface flow pathways.

Terrain ruggedness and human activities influence the distribution of Grauer’s gorillas ( Gorilla beringei graueri ) and eastern chimpanzees ( Pan troglodytes schweinfurthii ) in the Tayna Nature Reserve, Democratic Republic of Congo

Abstract The Albertine Rift Hotspot in east-central Africa is one of the most biodiverse regions in the world. It hosts a number of conservation-priority species, including Critically Endangered Grauer’s gorillas and Endangered eastern chimpanzees.
