Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Globally, illegal sport hunting can threaten prey populations when unregulated. Due to its covert nature, illegal sport hunting poses challenges for data collection, hindering efforts to understand the full extent of its impacts. We gathered social media data to analyze patterns of illegal sport hunting and wildlife depletion across Brazil. We

Diversity and Distributions, Volume 30, Issue 10, October 2024.Abstract Aim Global species distribution maps tend to be limited to a reduced number of species or are too coarse to inform ecological research and conservation actions at local scales. We developed a workflow to generate species range and area of habitat (AOH) maps tailored to local contexts based on expert information, community science observations ...

A photogrammetric approach for real‐time visual SLAM applied to an omnidirectional system
The Photogrammetric Record, Volume 39, Issue 187, Page 577-599, September 2024.This study presents a real‐time vSLAM for omnidirectional systems, adapting ORB‐SLAM with a rigorous equisolid‐angle projection model. Analysing a 140 m trajectory, it shows fewer discrepancies using hyperhemispherical images, outperforming a generic model like EUCM. Accuracy started at sub‐0.12 m, reaching metre‐level at the end.
