Behavioral analysis of animals in the wild plays an important role for ecological research and conservation has been mostly performed by researchers. We introduce action detection approach that automates this process detecting performing recognition on detected camera trap videos. Our is based SWIFT (segmentation with filtering tracklets), which we have already shown to successfully detect track wildlife videos, MAROON (mask-guided recognition), network are introducing here. The basic ideas...
Large carnivores can be a key factor in shaping their ungulate prey's behavior, which may affect lower trophic levels. While most studies on trade‐offs between food acquisition and risk avoidance by prey species have been conducted areas with limited human impact, are now increasingly returning to highly anthropogenic landscapes. Many of these landscapes dominated forestry, ungulate‐forestry conflicts an increasing issue. The aim this study was test if the indirect effects re‐colonizing...
Because animal carcasses often serve as reservoirs for pathogens, their location and removal are crucial in controlling the spread of diseases. During carcass decomposition, heat is emitted due to microbial activity development maggots. Recent studies have shown that infrared sensors can be used locate carcasses, but little known about factors influencing detection success. In this study, we investigated potential technology wild boar they play an important role African swine fever....
This study examined the effect of perceived predation risk imposed by lynx (Lynx lynx) and wolf (Canis lupus) on red deer (Cervus elaphus) foraging behavior under experimental conditions. We hypothesized that in response to large carnivore scent would increase their vigilance, although reducing frequency duration visits sites. Consequently, browsing intensity tree saplings was expected decrease, whereas a higher proportion more preferred species be browsed compensate for costs. stronger...
Abstract Terrestrial ecosystems are shaped by interacting top‐down and bottom‐up processes, with the magnitude of control large carnivores largely depending on environmental productivity. While carnivore‐induced numerical effects ungulate prey populations have been demonstrated in large, relatively undisturbed ecosystems, whether can play a similar role more human‐dominated systems is clear knowledge gap. As humans influence both predator variety ways, ecological impacts be modified. We...
Pellet counts are widely used to monitor ungulates but rely on the assumption that pellets of different species correctly identified in field. Recent studies question this using DNA barcoding techniques check field identification rates. For Europe, which is undergoing a rapid shift towards more diverse ungulate assemblages, such an assessment still missing. Using 3889 fecal samples from nine four European countries, we found average misidentification rates varied 0.6% for horse (Equus ferus)...
Abstract The recolonization of human‐dominated landscapes by large carnivores has been followed with considerable scientific interest; however, little is known about their interactive effect on ungulate foraging behavior. This study compared the risks imposed humans and lynx behavior examining effects browsing intensity (at two spatial scales), diet quality, tree species selection. We hypothesized that: (1) in areas high risk would be reduced; (2) interact habitat visibility at a fine scale,...
Abstract Hunting triggers behavioral responses in wildlife that may have important consequences for conservation and management. We studied movement habitat selection 51 global positioning system‐collared red deer ( Cervus elaphus ) response to 63 large‐scale x̄ = 18.8 km 2 drive hunts conducted 2015‐2022 on a military training area southern Germany. The were characterized by low density of beaters dogs avoid rapid long‐distance displacement deer. determined if spatial differed various...
Abstract Antipredator behaviors allow prey to mitigate the impacts of their predators. We investigated antipredator responses two herbivore species, roe deer and European hare, one mesopredator, red fox, toward predation risk imposed by lynx wolf. collected data (using camera traps) on visitation frequency vigilance behavior olfactory predator stimuli during 158 standardized scent trials in five areas across Europe, where wolves either occurred or had been absent for centuries. After a...
Hunting and its impacts on wildlife are typically studied regionally, with a particular focus the Global South. can, however, also undermine rewilding efforts or threaten in North. Little is known about how hunting manifests under varying socioeconomic ecological contexts across South Herein, we examined differences commonalities characteristics an exemplary South-North gradient approximated by Human Development Index (HDI) using face-to-face interviews 114 protected area (PA) managers 25...
Behavioural changes of prey towards large carnivores can have profound impacts on populations and the ecosystems they inhabit. However, European studies thus far only found limited support for behavioural to returning carnivores. We examined trade-off between forage quality perceived predation risk an ambush (Eurasian lynx; Lynx lynx) cursorial predator (wolf; Canis lupus) response red deer (Cervus elaphus) in experimental set-up within semi-natural grasslands forest patches. hypothesized...
Ungulate browsing often impairs tree regeneration, thus preventing the achievement of economic or conservation goals. Forest ungulate management would benefit from a practical decision tool that facilitates method selection wide range monitoring methods and indicators currently available. In this study, we first provide an overview different browsing-impact applied. We then present newly developed matrix for evaluation can assist forest stakeholders in choosing best suited to their needs,...
