Abstract Co-occurrence and spatial temporal overlap of sympatric jungle leopard cats are influenced by habitat preferences, interspecific competition. Understanding these factors influence is crucial for developing effective conservation strategies. We conducted a camera survey in Parsa‒Koshi Complex (PKC), Nepal during December 2022–March 2023 to investigate influencing occupancy between ( Felis chaus ) Prionailurus bengalensis ).

Biodiversity is a vital aspect of an ecosystem and investigating its formation maintenance vital. Maintaining biodiversity notably requires clear understanding the mechanisms underlying species coexistence. However, in Anthropocene, absence large carnivores most areas has reduced number relatively intact ecosystems suitable for coexistence research. The mountains Southwest China, hotspot with low anthropogenic disturbance, offer potentially area studying carnivore coexistence, especially Xinlong region Sichuan. To understand small carnivores, we used infrared cameras to investigate their spatiotemporal activity. We explored interspecific niche differentiation carnivore' responses top predators human disturbances using occupancy modeling avoidance-attraction ratios (AARs). results were as follows: 1) different exhibited unique spatial temporal predators, leopard cats (Prionailurus bengalensis) preferring occupy occupied by leopards (Panthera pardus), whereas yellow-throated martens (Martes flavigula) red foxes (Vulpes vulpes) remained spatially independent leopards; 2) activities did not significantly affect but time-resistant behavior toward humans domestic cattle; 3) observed avoidance between other (yellow-throated foxes). Overall, our study highlights complex unexpected behavioral survival strategies animals within integrated community. In future, aim further wildlife communities this elucidate potential roles ecological

Abstract The Amazon rainforest faces escalating human disturbances such as logging, mining, agriculture, and urbanization, leading to the conversion of primary forest into matrix habitat. This transformation's impact on mesocarnivores, specifically ocelots ( Leopardus pardalis ), is still largely unknown. In 2021, we deployed camera traps across a 174 km 2 study area in Las Piedras, Madre de Dios, Peru, containing mixed land use protected forests. Utilizing kernel density functions, compared temporal activity patterns employed spatially explicit capture‐recapture (SECR) models assess density, encounter probability, movement by habitat trail type, well sex. Of 293 captures, identified 39 (21 females, 18 males), estimating an average 31.46 (SE 5.15) individuals per 100 with no significant difference between mixed‐use areas. Baseline detection varied sex, male female home ranges estimated at 17.14 4.10 , respectively. Ocelot differed area, increased nocturnality areas higher impact. Our SECR results highlight that habitats can support ocelot populations, emphasizing need for further research demographics human‐modified facing varying degrees anthropogenic disturbance.

Abstract Fragments and edges account for most remaining forest habitats globally. Apex predators megaherbivores often decline in these degraded while smaller generalist omnivores can persist or thrive edges, especially if they utilize nonnative resources (“cross‐boundary food subsidies”). Outcomes small‐medium carnivores (mesopredators) remain unclear idiosyncratic. We tested responses of a widespread common mesopredator to the composition adjacent nonforested areas using 91 camera trapping surveys Southeast Asia. Leopard cats ( Prionailurus bengalensis javanensis ) showed hump‐shaped relationship with cover positive association oil palm plantations, but did not increase near other types land cover. cats' success appears due their hunting abundant rodent prey inside providing natural pest management farmers. Abundant leopard also hunt suppress native small vertebrates, which may trigger negative ecological cascades biodiversity edges.

Understanding the population status of a species is vital for their conservation. Over last two decades, multiple methods surveying lion (Panthera leo) populations have been designed and tested. Each strengths weaknesses, with different applications, varying levels reliability, accuracy precision. We conducted PRISMA systematic review to identify assess survey estimating abundance. searched Web Science Google Scholar peer reviewed papers between January 1991 December 2022. Sixty-five were included, some using or study sites; when these separated, 93 studies identified. Seven broad lions identified: call ups (34.8% studies), spoor counts (32.5%), direct observations (15.7%), capture recapture elements (12.4%), camera trap-based capture-recapture analysis (4.5%), genetic surveys (3%) distance-based (1.1%). Our literature suggests that most reliable determining density abundance are surveys. Genetic combined spatially-explicit also hold significant potential. Due lack reliability tendency over-estimate populations, not recommended further recommend harmonized be developed can produce comparable estimates, which used inform conservation decisions across range.

Background: Human activities have resulted in a rapid increase of modified habitats proximity to wildlife the Himalaya. However, it is crucial understand extent which human habitat modification affects wildlife. Mesocarnivores generally possess broader niches than large carnivores and adapt quickly activities. Here, we use case study western Himalaya test hypothesis that disturbance influenced mesocarnivore use. Methods: We used camera trapping mitochondrial DNA-based species identification from faecal samples obtain detections. then compared responses mesocarnivores between an anthropogenic site less disturbed park along contiguous gradient quality. The non-linear pattern species-specific selection factors responsible for space usage around villages was captured using hierarchical generalized additive modelling (HGAM) non-metric multidimensional scaling (NMDS) ordination. Results: Wildlife occurrences varied by species. Leopard cat red fox were only terrestrial occurred both park. found shift detected types. For instance, showed towards high terrain ruggedness (0.5 0.7 TRI) low NDVI (−0.05 0.2) but no such specific site. Further, leopard moderate slope (20°) medium (0.5) prominent selections results revealed their constrained behaviour further supported intensive close houses, agricultural fields trails villages. Conclusions: Our indicate shifts human-modified habitat. In future, this suggests possibility conflict disease spread affecting people Therefore, highlights requisite rapidly growing expansions impact. management strategies need integrated focus garbage disposal strategies, especially human-wildlife interface area.
