Common palm civets (Paradoxurus hermaphroditus) are positively associated with humans and forest degradation with implications for seed dispersal and zoonotic diseases
<p>Habitat loss and degradation can undermine wildlife communities and ecosystem functioning. However, certain generalist wildlife species like mesopredators and omnivores can exploit these disturbed habitats, sometimes leading to population increases (e.g., "mesopredator release" in degraded areas). Although mesopredator release may cause negative effects on food webs and zoonotic disease management, some disturbance-tolerant species may help perpetuate important ecological interactions, such as seed dispersal.</p> <p>We evaluated the habitat associations of common palm civets (Paradoxurus hermaphroditus), which are widespread generalist mesopredators in Southeast Asia. Common palm civets are also high-quality seed dispersers, and potential zoonotic disease hosts.</p> <p>We used published and new camera trapping data to map their probability of presence across Southeast Asia and evaluate regional-scale associations between capture rates and habitat variables such as elevation, ecoregion intactness, and Human Footprint Index, among others. We also assessed the influence of habitat variables on their relative abundance at the local scale.</p> <p>At the regional scale, we found that common palm civets showed significant positive associations with landscapes characterized by lower ecoregion intactness, higher Human Footprint Index, and lower elevations. At the local scale, their relative abundance showed a significant positive association with higher Human Footprint Index, but only to a certain point, after which it started decreasing. They also favored lower elevations at the local scale.</p> <p>These multi-scale results indicate that common palm civets' abundance can increase under certain levels of human disturbances, consistent with the "mesopredator release" hypothesis. This suggests they may be crucial seed dispersers in degraded forest landscapes, especially where more sensitive seed dispersers have disappeared. Our results are also consistent with previous studies reporting that habitat degradation increases populations of potential zoonotic disease hosts, and thus risks of transmission to humans.</p>

Megafruit and megafauna diversity are positively associated, while megafruit traits are related to abiotic factors, in Tropical Asia
<p class="Body"><b>Aim</b></p> <p class="Body">For tens of millions of years, herbivorous megafauna were abundant across the globe, fulfilling important ecological roles including seed dispersal. Megafruits are very large fruits that are dispersed most effectively by megafauna. However, megafruits also occur in ecosystems where megafauna are extinct or were never present, emphasizing our incomplete understanding of megafauna-megafruit relationships. Here we use the complex biogeography of tropical Asia to investigate how megafruit diversity and traits are associated with the diversity of megafauna, smaller animals, and abiotic factors.</p> <p class="Body"><b>Location</b></p> <p class="Body">Tropical Asia, from the Indian subcontinent in the west to tropical China in the north to the Maluku archipelago (Indonesia) in the east.</p> <p class="Body"><b>Time period</b></p> <p class="Body">Late Pleistocene to the present day.</p> <p class="Body"><b>Major taxa studied</b></p> <p class="Body">Megafauna (body weight >500 kg) that consume fruits, including stegodons, elephants, rhinoceroses, giant tapirs, and large bovids. Fleshy-fruited plant species across the region with a fruit width >40 mm (i.e., megafruits).</p> <p class="Body"><b>Methods</b></p> <p class="Body">We compiled a list of all megafruits along with selected plant, fruit, and seed traits in 16 subregions across tropical Asia. We explored biogeographic patterns in megafruit diversity and traits in relation to the diversities of past and present megafauna, large- and medium-sized animals and abiotic factors (mean temperature, mean precipitation, precipitation seasonality, insularity).</p> <p class="Body"><b>Results</b></p> <p class="Body">We identified 496 megafruits in tropical Asia. Megafruit diversity was highest in subregions with high megafaunal diversity, particularly extant species. Megafruit traits were influenced most strongly by abiotic factors (mainly temperature and land area), and weakly by megafauna and smaller dispersers.</p> <p class="Body"><b>Main conclusions</b></p> <p class="Body">Our results are consistent with megafauna maintaining or responding to megafruit diversity, but variation in megafruit traits is primarily associated with abiotic factors. Given the massive megafaunal losses in tropical Asia since the Late Pleistocene, it is important to identify fruit traits that can increase megafauna-dependence and thus vulnerability to these losses.</p>
