Changes in topography, such as terrain elevation and slope, are an important source of landscape complexity influencing the ecology animals, particularly mountainous landscapes. In landscapes animals navigate changes slope their daily movement. Despite importance topographic variation, studies animal tend not to explicitly consider those effects on species detection. We deployed a broad‐extent, coarse resolution camera‐trapping system across with considerable quantified influence variables detection probability conditional occurrence for multiple mammal species. Specifically, we examined fine‐scale steepness position (i.e. ridges, mid‐slopes or valleys) 14 at camera‐traps. found that increased gently sloping six decreased steepest slopes sampled three these additional Among four other species, changed according local though directionality responses varied among Several primarily meso‐carnivores well larger‐bodied like mule deer black bears, were more detectable gentle than flat terrain. This pattern suggests many may use moderately steep resources heterogeneity they provide. Topographic had comparatively less effect probabilities, suggesting this variable does have strong space regions.

Abstract Estimating habitat and spatial associations for wildlife is common across ecological studies it well known that individual traits can drive population dynamics vice versa. Thus, commonly assumed individual‐ population‐level data should represent the same underlying processes, but few have directly compared contemporaneous representing these different perspectives. We evaluated circumstances under which collected from Lagrangian (individual‐level) Eulerian (population‐level) perspectives could yield comparable inference to understand how scalable information population. used Global Positioning System (GPS) collar (Lagrangian) camera trap (Eulerian) seven species simultaneously in eastern Washington (2018–2020) compare inferences made survey fit respective streams resource selection functions (RSFs) occupancy models estimated habitat‐ space‐use patterns each species. Although previous considered whether generated information, ours first make this comparison multiple specifically ask two differed depending on focal found general agreement between predicted distributions most paired analyses, although specific relationships differed. hypothesize discrepancies arose due differences statistical power associated with GPS‐collar sampling, as mismatches data. Our research suggests individual‐based sampling methods capture coarse population‐wide a diversity of species, results differ when interpreting wildlife‐habitat relationships.

Abstract Predators compete for resources aggressively, forming trophic hierarchies that shape the structure of an ecosystem. Competitive interactions between species are modified in human‐altered environment and become particularly important where introduced predator can have negative effects on native prey species. The trans‐Himalayan region northern India has seen significant development tourism associated infrastructure over last two decades, resulting many changes to natural setting landscape. While tourism, combined with unmanaged garbage facilitate red fox ( Vulpes vulpes ), it also allows free‐ranging dogs Canis lupus familiaris mesopredator thrive, possibly more than fox. We look at little‐known competitive dynamics these meso‐carnivores, as well their intra‐guild region's top carnivores, snow leopard Panthera uncia ) Himalayan wolf chanco ). To study four we performed multispecies occupancy modeling analyzed spatiotemporal predators using camera trap data. collected scat samples calculate dietary niche overlaps determine extent competition food carnivores. found that, after controlling habitat covariates, site use was related positively use, but negatively dog use. In addition, predators, is, wolf, while themselves As anthropogenic impacts increase, find coexist this resource‐scarce landscape through or segregation, implying limited resources. Our research adds scant ecological knowledge improves our understanding community ecosystems.

Abstract Primate social organizations, or grouping patterns, vary significantly across species. Behavioral strategies that allow for flexibility in patterns offer a means to reduce the costs of group living. Chimpanzees ( Pan troglodytes ) have fission‐fusion system which temporary subgroups (“parties”) change composition because local socio‐ecological conditions. Notably, western chimpanzees P. t. verus are described as showing higher degree bisexual bonding and association than eastern chimpanzees, female schweinfurthii thought be more solitary chimpanzees. However, reported comparisons sociality currently depend on small number study groups, particularly variation methods. The inclusion additional communities direct comparison using same methods essential assess whether subspecies differences hold this behaviorally heterogeneous We explored differs between two motion‐triggered camera technology definitions measures. compare party size (party type, sex ratio) Gahtoy community Nimba Mountains (Guinea) Waibira Budongo Forest (Uganda). Once potential competition resources such food mating opportunities were controlled for, did not substantially influence individuals party. found sex‐ratio, indicating males party, Waibira; pattern was driven by greater likelihood all‐female parties. This finding is opposite what expected where female‐only parties predicted common. Our results highlight chimpanzee sociality, caution against level generalizations.

Abstract The behavior and abundance of sympatric predators can be affected by a complex dominance hierarchy. strength antagonistic interactions in predator communities is difficult to study remains poorly understood for many assemblages. Predators directly indirectly influence the broader ecosystem, so identifying relative importance competition, prey, habitat shaping has broad conservation management implications. We investigated space use among five species (black bear [ Ursus americanus ], bobcat Lynx rufus coyote Canis latrans mountain lion Puma concolor gray wolf lupus ]) across three temporal scales northern Idaho, USA. used camera trap data test whether potentially subordinate spatially avoided dominant how prey availability influenced those relationships. found few instances avoiding only at finest scale our analyses. Instead, features generally patterns coarser whereas competitor presence finer scales. Co‐occurrence was positively associated between coyotes bobcats timescales mesopredators apex timescales. Bobcats lions temporarily delayed sites recently visited black bears, respectively. And all sooner following detection areas with higher abundances (primarily white‐tailed deer Odocoileus virginianus ]). Our results suggest attraction shared habitats resources community more than avoidance competitors. propose that effects interspecific on distributions were most evident because their trophic position requires balancing risks rewards predators, other mesopredators. In addition, relatively high densities common source likely facilitated spatial coexistence this community. demonstrates value simultaneously assessing multiple different spatiotemporal discern relationships within guild.

Abstract Terrestrial wildlife species are important taxa in the recovery of ecosystems following dam removal. Their presence can shape ecosystem recovery, signal restoration function, and influence food web dynamics nutrient transfer. This study investigated terrestrial mammal communities within rehabilitation area Gunung Leuser National Park, Indonesia, using camera trap data collected between May December 2023. The results revealed a diverse group mammals, including endangered species, with distinct activity patterns. Eight were present, most dominant being Sus scrofa . Only one four keystone TNGL, Elephas maximus sumatranus , was present. Overlapping patterns among predator suggest potential interactions resource partitioning. These findings underscore importance habitat for biodiversity conservation highlight need ongoing monitoring to assess long-term impacts efforts on communities.
