Mammal Study

The pollination modes of plants vary among regions owing to faunal variations; however, knowledge of pollinators in tropical montane Asia is insufficient. Here, we elucidate the pollination system of Mucuna thailandica (Fabaceae), a plant endemic to the montane forest of Thailand. The genus Mucuna exhibits a distinctive pollination mechanism called "explosive opening″. The stamens and pistils of Mucuna flowers are covered by a pair of keel petals, and pollination is only possible when a flower is opened by a pollinator, which exposes stamens and pistil. In bagging experiments, unopened M. thailandica flowers did not bear fruit, indicating that an explosive opening was necessary for successful pollination. Automatic camera surveys showed that squirrels (Callosciurus finlaysonii/erythraeus complex and Dremomys rufigenis), masked palm civets (Paguma larvata), and northern treeshrews (Tupaia belangeri) opened the flowers explosively. Among them, the C. finlaysonii/erythraeus squirrels opened flowers most frequently, and three flowers bore fruits. Thus, C. finlaysonii/erythraeus squirrels may be effective pollinators of M. thailandica. Opening the flowers grants pollinators access to a large volume of nectar with a high sugar concentration as a reward. Our findings suggest that the role of nonflying mammals as pollinators in tropical Asian montane forests may be greater than previously thought.

To investigate diets of two sympatric carnivoran species, a leopard cat (Prionailurus bengalensis) and a yellow-throated marten (Martes flavigula), in Mt. Jeombongsan, Korea, we elucidated their diet compositions using fecal DNA. Their feces were collected from October 2015 to October 2018. After extracting DNA from fecal samples, the mitochondrial 12S rRNA gene of vertebrates and the rbcL regions from plants were amplified. Prey DNA was detected by cloning-based sequencing using blocking primers. A variety of rodents such as Muridae and Cricetidae and birds such as Passeriformes and Galliformes were frequently detected in feces of leopard cats and yellow-throated martens, suggesting that these taxa were important prey of the two carnivoran species. Regarding plant food sources, genus Prunus was frequently detected in feces of the leopard cat and genus Actinidia in feces of the yellow-throated marten, indicating that these two Carnivora species were not exclusively carnivorous. The maximum numbers of vertebrate prey taxa were estimated using rarefaction curves. Our results suggest that both species have roles as top predators in Mt. Jeombongsan, demonstrating significant differences in the diets of the two sympatric Carnivora species.

In Jangsudae of Seoraksan National Park, South Korea, 14 mammal species have been listed, including ten medium- and large-sized species; additionally, this region is an important habitat for the endangered long-tailed goral (Naemorhedus caudatus). In this study, a camera trap survey was conducted over 103 monitoring days at 18 sites in Jangsudae to evaluate the minimum trapping effort (MTE) needed to detect the ten listed mammal species. The most photographed species were the long-tailed goral, wild boar (Sus scrofa), and Asian badger (Meles leucurus), accounting for 77.1% (n = 366) of the total independent photographs. Long-tailed goral, the most frequently captured mammal species (44.8%), was captured at 17 camera sites (relative abundance index = 206.8). According to the rarefaction analysis, 1840 camera days (102.2 monitoring days at 18 camera sites) were required to photograph all ten resident species. Moreover, at least 1010 and 664 camera days were required to detect 95% and 90% of the ten residential species, respectively. MTE was evaluated in summer when wild species were highly detectable owing to their high activity. Future studies should evaluate MTE through one-year long-term monitoring that includes all four seasons, and compare the results with those of this study.
