Citizen science project on urban canids provides different results from camera traps but generates interest and revenue

open access: yesWildlife Biology, EarlyView.
As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...

GPolylla: Fully GPU-accelerated polygonal mesh generator [PDF]

open access: yesarXiv
This work presents a fully GPU-accelerated algorithm for the polygonal mesh generator known as Polylla. Polylla is a tri-to-polygon mesh generator, which benefits from the half-edge data structure to manage any polygonal shape. The proposed parallel algorithm introduces a novel approach to modify triangulations to get polygonal meshes using the half ...

Documenting den characteristics of bears and wolves in the Greater Yellowstone Ecosystem using LIDAR technology

open access: yesWildlife Society Bulletin, EarlyView.
Previous studies have documented den site characteristics through physical measurements recorded by researchers in the field. Using the light detection and ranging (LiDAR) sensor onboard an Apple iPad Pro, we scanned the interior of black and grizzly bear dens (n = 9) located in the Greater Yellowstone Ecosystem (GYE) to generate point clouds of den ...

Leibniz rule for wedge product in discrete exterior calculus on general polygonal meshes [PDF]

open access: yesarXiv
Discrete exterior calculus offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. In this work, we present a wedge product on 2-dimensional pseudomanifolds, whose faces are any polygons. We prove that this polygonal wedge product is compatible with the discrete exterior derivative in the sense ...

Cs4Ca[Si8O19]: a new mixed tetrahedral–octahedral oxosilicate, its topological features and comparison with other interrupted framework silicates

open access: yesActa Crystallographica Section B, EarlyView.
The crystal structure of the mixed tetrahedral–octahedral framework silicate Cs4Ca[Si8O19] has been solved. A topological analysis of the present compound and other interrupted framework silicates is presented.Single crystals of a previously unknown caesium calcium silicate with the composition Ca4Ca[Si8O19] have been obtained during a systematic study
