It remains common practice for zoos to chop animal diets into small pieces, even though there is limited evidence support this practice. important that the purported benefits of chopping food are investigated, determine whether any welfare. This study investigates impact presentation on behaviour binturong (Arctictis binturong), a large Asian viverrid, at Beale Wildlife Park in United Kingdom. For study, was provided three sizes: very finely chopped, and whole preference binturongs investigated alongside time taken keepers prepare diets. There were relatively few behavioural differences when with sizes. Only behaviours, namely feeding, manipulation locomotion significantly more frequent whole, whilst vocalisations less condition. When items large, appeared take item move elsewhere eat, thus moving away from one another, which therefore reduces opportunities aggression or stealing. suggests may have terms reduced monopolisation, especially housed pairs groups. Keepers saved almost five minutes preparing as opposed chopped size. Given potential benefits, plus keeper saved, viable option feeding binturongs.

Abstract Identification of highly biodiverse areas has become a crucial step in protecting species richness, especially considering the rapid collapse biodiversity and limited funds available to avert, far less reverse, these trends. Therefore, we aimed identify most important for conservation specified mammalian groups Southern Asia, region rich hotspots threatened by increasing rates habitat loss other anthropogenic activities. To achieve this, modelled occupancy ungulates small, medium large carnivorans at 20 study sites across identified richness. We analysed variation estimated space use between different ranked according their predicted importance conservation. Our results reveal significant positive correlation spatial utilization patterns competitive carnivores, yet no among carnivores prey species, suggesting that impacts are constraining coexist only few remaining suitable areas, superseding interactions guilds.

Abstract The urgent need to mitigate and adapt climate change necessitates a comprehensive understanding of carbon cycling dynamics. Traditionally, global cycle models have focused on vegetation, but recent research suggests that animals can play significant role in dynamics under some circumstances, potentially enhancing the effectiveness nature‐based solutions change. However, links between animals, plants, remain unclear. We explored complex interactions defaunation ecosystem Earth's most biodiverse carbon‐rich biome, tropical rainforests. Defaunation patterns seed dispersal, granivory, herbivory ways alter tree species composition and, therefore, forest above‐ belowground. Most studies we reviewed show reduces storage 0−26% Neo‐ Afrotropics, primarily via population declines large‐seeded, animal‐dispersed trees. Asian forests are not predicted experience changes because their high‐carbon trees wind dispersed.

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.

The purpose of the study was to observe behaviour daily and investigate its management practices at Semarang Zoo. Scan sampling used monitor behaviours three solitary binturongs in 3.0 × 1.5 m enclosures which reflected their nature. Diurnal observations revealed that spent over 50% time sleeping resting, consistent with nocturnal habits. A diet papaya, banana, cucumber, chicken meat provided support lives. Management strategies such as enclosure cleaning, freshwater supply, health care every months were implemented. It suggested welfare could be enhanced by adding enrichment activities increasing variety diets. Observations during daylight hours highlighted need for further studies on both diurnal activity patterns. Conservation institutions believed research phylogenetics genetic diversity critical effective species conservation. Based detailed observation analysis, it found significantly improved captive binturongs. These findings provide essential insights into binturong care, development best zoo well ongoing conservation initiatives.

Abstract Habitat loss and fragmentation profoundly impact Southeast Asian rainforest biodiversity ecosystem functioning. While many larger herbivores are hunted area‐demanding apex predators lost from degraded forests (logged forests, forest fragments edges), smaller herbivore species may be comparatively resilient or even benefit a release competition predation in forests. Mousedeer (or chevrotains) the Tragulus genus some of world's smallest ungulates (1.5–4.5 kg) widespread Asia. We evaluated mousedeer habitat associations at three spatial scales. At regional scale, presence‐only distribution modelling suggested negatively associated with aridity elevation. landscape variation capture rates among 186 published camera trapping studies degradation local scale (within landscapes), abundance sampled 1218 cameras 10 landscapes analysed hierarchical humans diel activity patterns shifted towards increased nocturnality possibly to avoid interactions diurnal humans.
