Abstract Cercopithecus monkeys are a species‐rich genus generally considered arboreal frugivores with widespread distribution in sub‐Saharan African forests. We studied largely undocumented species threatened by habitat fragmentation, denti , during 3 months 2017 small forest fragment of Nyungwe National Park, Rwanda. C. denti's diet was composed about 58% leaves and 18% fruits. They spent most their time 10–20 m above ground secondary open areas. This first systematic study shows capacity for highly folivorous diet, supporting arguments that have flexible diets, likely enabling persistence fragments.

The increasing demand for forest land, habitat disturbance, and fodder shortages have intensified Man-Animal Conflicts (MAC) worldwide. This study analyzes both qualitative quantitative data to assess the status of MAC in Karnataka, leveraging 2,03,297 geo-tagged conflict cases are reported by Karnataka Forest Department's (KFD) since 2014 2024. Earlier all records were manually generated stored as hardcopies, a traditional method documentation. To implement advance technologies, which makes tracking easier, KFD decided design digital platform, under e-Governance timely response on issue its validation. As result 2019, online database was generated, tested functioning, launched e-Parihara website, mobile app management MAC, helps provide ex-gratia relief various types damages caused wildlife. paper comprehend real-time available also digitised from 2014. allows officials document with photos geo-stamped damage details. limitation this web portal is access restricted proper platform ensures transparency efficiency integrating SMS notification alerts applicants about claim progress. employs flowchart automated workflows process compensation claims, based government directives, generate official memorandums (OMs).

ABSTRACT Wild primates face a wide range of anthropogenic influences globally that impact their health, fitness, and survival. One area potential has been particularly understudied is the supplementation wild primate diets with human foods. Although consumption foods represents substantial dietary change for primates, knowledge how it impacts physiology behavior limited. Here we explore food by comparing gut microbiomes free‐ranging brown howler monkeys ( Alouatta guariba ) in periurban Brazil do or not have access to We found consuming had reduced microbial diversity relative abundances fiber degrading taxa, which associated negative health consequences other animals, including humans. However, effect size these differences was relatively small varied over time. Additionally, composition microbiome significantly across months, regardless suggest biology this monkey population minimally impacted Further empirical research will help clarify relationship between populations, facilitating conservation applications.

Habitat degradation poses a critical threat to the Malabar slender loris (Loris lydekkerianus malabaricus), yet little is known about its microhabitat requirements in intact forest. In Aralam Wildlife Sanctuary, we combined nocturnal trail surveys (337 sightings) with plotless sampling of 2830 trees (86 species from 35 families) characterize both vegetation structure and presence. Our results show that lorises occur almost exclusively mildly degraded wet evergreen secondary moist deciduous subcanopies, where understory climber networks provide continuous pathways. Individuals are most often encountered at heights 5–15 m—ascending into higher strata as night progresses—reflecting balance between foraging access predator avoidance. Substrate analysis revealed strong preferences for twigs ≤ 1 cm (36.98%) small branches 2–5 diameter, oriented obliquely minimize energetic costs maintain stability during slow, deliberate arboreal locomotion. Day-sleeping sites were overwhelmingly located within dense tangles lianas on large-girth trees, intertwined stems thorny undergrowth offer concealment mammalian avian predators. Vegetation documented near-equal mix (50.6%) (49.4%) species—including 26 endemics (18 restricted Western Ghats)—with Aporosa cardiosperma emerging abundant riparian pioneer, suggesting ecological resilience potential simplification fragmented patches. Complementing field observations, our recent habitat-suitability modeling indicates broad-scale climatic anthropogenic factors—precipitation patterns, elevation, proximity roads—are strongest predictors occupancy, underscoring interplay landscape-level processes structure. Together, these findings highlight imperative multi-strata forest restoration—planting insect-hosting native maintaining canopy networks, integrating “mini-forest” modules—to recreate structural complexity vital conservation broader Ghats biodiversity.

We report a novel observation of ground nesting behavior in couple Aotus griseimembra within successional inter-Andean Forest patch Colombia. This behavior, previously unrecorded for strictly arboreal primates the Genus Aotus, challenges conventional understanding. The monkeys exhibited typical species actions but sought refuge on ground, possibly influenced by habitat alterations. Their visits to sleeping site were monitored and confirmed vulnerability predators, competitors forest patch. These findings call attention further research into response strategies neotropical environmental stressors disturbance.

Accurately assessing primate diets is important in studies of behavioral ecology and evolution. While previous research has compared sampling methods (scan, focal), we examined how schedule influences accuracy dietary measures. We define as the combined distribution (random vs. consecutive) frequency days within a given month. Under field conditions, time may be required to locate study group, therefore also subtracted 1, 2, or 3 h from beginning all non-consecutive each mimic observation lost search. From dense (near daily) 5-year record feeding behavior derived focal animal follows adult females five wild blue monkey (Cercopithecus mitis) groups, created data subsets matching various schedules, monthly measures calculated subset those based on full set. These included (1) proportion fruit, (2) diet composition (three top-ranked food items), (3) species richness plant diet, (4) Shannon-Wiener diversity index species, (5) Holmes-Pitelka expressing overlap with used generalized linear mixed models assess type (a combination hours lost) relate subset's deviation set, where smaller (or higher chance matching, for composition) implies greater accuracy. For measures, increasing increased The response varied among but types generally differed more at lower frequencies. Deviation widely between some schedules resulted values large percentage differences "full" data. Accordingly, when designing comparing studies, researchers should consider influence interest.

Sapajus nigritus popularly known as southern black-horned capuchin monkey is a medium-sized arboreal primate endemic to the Atlantic Forest. They have high trophic and behavioral plasticity, which allows them adapt different environments, including highly fragmented landscapes urban areas. This study aimed understand patterns variations in diet feeding activity of monkeys living an area by comparing areas with habitat composition.
