Quantifying hunting-induced defaunation As the human population grows and increasingly encroaches on remaining wildlife habitat, hunting threatens many species. Benítez-López et al. conducted a large-scale meta-analysis of trends impacts across tropics (see Perspective by Brashares Gaynor). Bird mammal populations were considerably lower in areas where occurred. Although commercial proximity to roads urban centers most damaging factors, all had worrying impacts, even protected areas....
COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance 2300 terrestrial mammals (43 species) during the same period 2019. Individual responses were variable with no change average or behavior, likely due lockdown conditions. However, under strict 10-day 95th percentile displacements increased by 73%, suggesting permeability. Animals'...
Abstract Animal population sizes are often estimated using aerial sample counts by human observers, both for wildlife and livestock. The associated methods of counting remained more or less the same since 1970s, but suffer from low precision accuracy estimates. Aerial cost‐efficient Unmanned Vehicles microlight aircrafts with cameras an automated animal detection algorithm can potentially improve this accuracy. Therefore, we evaluated performance multi‐class convolutional neural network...
Wildlife crime is one of the most profitable illegal industries worldwide. Current actions to reduce it are far from effective and fail prevent population declines many endangered species, pressing need for innovative anti-poaching solutions. Here, we propose test a poacher early warning system that based on movement responses non-targeted sentinel animals, which naturally respond threats by fleeing changing herd topology. We analyzed human-evasive patterns 135 mammalian savanna herbivores...
Animals respond to environmental variation by changing their movement in a multifaceted way. Recent advancements biologging increasingly allow for detailed measurements of the nature movement, from descriptors animal trajectories (e.g., using GPS) body part movements tri-axial accelerometers). Because this multivariate richness data complicates inference on influence studies generally use simplified statistical analyses. However, doing so limits as requires that can be fully considered an analysis.

Abstract Grouping behaviour of prey animals is thought to be mainly driven by fear predation and resource scarcity. Fear often leads small inter-individual distances, while scarcity the opposite. Consequently, it believed that number individuals in a group (group size) an emergent property trade-off between acquiring scarce resources preventing predation. We analysed whether size can reliably used as proxy for this trade-off, using deterministic attraction-repulsion agent-based model...
The decrease in African rhino poaching incidents since 2015 has prompted many to praise the effectiveness of anti-poaching efforts. To test validity this statement, we calculated how far poachers moved on average from 2007 2022 find a context dwindling densities. These calculations demonstrate that total pressure remained persistently high 2013. Given concurrently declining arrest rates, our results show protection practices past decade have been insufficient. Instead, propose rhinos can...
Animal movement arises from complex interactions between animals and their heterogeneous environment. To better understand the process, it can be divided into behavioural, temporal spatial components. Although methods exist to address those various components, remains challenging integrate them in a single analysis. We present an analytic workflow that integrates components of process interactions, which also allows for assessment relative importance construct daily cyclic covariate...
ABSTRACT Ungulates serve as the primary carrion source for facultative scavengers in European ecosystems. In absence of large carnivores, such wolves ( Canis lupus ), human hunting leftovers are main these scavengers. Additionally, wild boars Sus scrofa ) heavily culled many ecosystems and both a significant prey species well key scavenger. Nowadays, re‐establishing their historical home ranges. However, it remains unclear how presence influences population dynamics under different scenarios...
Advances in GPS telemetry technology have enabled analysis of animal movement open areas. Ecologists today are utilizing modern analytic tools to study behaviors from large quantity coordinates. Analytic with automatic event extraction functionality can be used investigate potential interactions between animals by locating relevant segments trajectories. However, such automation easily overlook the spatial, temporal, social context as well data problems. To this end, paper explores visual...

Abstract Animal movement arises from complex interactions between animals and their heterogeneous environment, making it challenging to capture the process in a single analysis. This has lead bias towards lower-dimensional representations of such analyses. In order better understand animal movement, its multiple components should be included addressed simultaneously. We present an analytic framework that integrates behavioural , spatial temporal interactions, allows for assessing relative...
