July, pp. 1009–1025, 2021, ISSN: 20715773. Abstract | BibTeX | Tags: biodiversity, distribution map, herpetofauna, museum specimens, Southeast Asia, species richness @article{Kusrini2021, Java and Bali are important as the most populated islands and as economic centres in Indonesia, and Java is the seat of the national government. Although a series of reports exists to document the species richness of amphibians and reptiles on those islands, there has so far been no unified compilation of their spatial distributions. The aim of this study was to quantify sampling effort and species richness for the herpetofauna of Java and Bali from specimen collections as well as published and unpublished literature sources, and to develop a map of spatial distributions as of 31 December 2017 – the first herpetofaunal atlas for any part of Indonesia. We found that the western part of Java has been better sampled than all other areas. Amphibian and reptile species richness on both islands is correlated with sampling effort, and sampling has occurred primarily in conservation areas. New species are still being described, not only from conservation areas but also from human-dominated landscapes. There is a need to increase the sampling effort on both islands, including outside of conservation areas. Development of a citizen science program focused on amphibians and reptiles would aid in increasing our understanding of species distributions in these islands and throughout Indonesia. |

Abstract | Links | BibTeX | Tags: biodiversity, climate change, conservation, mammal, tropical landscape @article{Condro2021a, The Leuser Ecosystem is one of the essential landscapes in the world for biodiversity conservation and ecosystem services. However, the Leuser Ecosystem has suffered many threats from anthropogenic activities and changing climate. Climate change is the greatest challenge to global biodiversity conservation. Efforts should be made to elaborate climatic change metrics toward biological conservation practices. Herein, we present several climate change metrics to support conservation management toward mammal species in the Leuser Ecosystem. We used a 30-year climate of mean annual temperature, annual precipitation, and the BIOCLIM data to capture the current climatic conditions. For the future climate (2050), we retrieved three downscaled general circulation models for the business-as-usual scenario of shared socioeconomic pathways (SSP585). We calculated the dissimilarities of the current and 2050 climatic conditions using the standardized Euclidean distance (SED). To capture the probability of climate extremes in each period (i.e., current and future conditions), we calculated the 5th and 95th percentiles of the distributions of monthly temperature and precipitation, respectively, in the current and future conditions. Furthermore, we calculated forward and backward climate velocities based on the mean annual temperature. These metrics can be useful inferences about species conservation. Our results indicate that almost all of the endangered mammals in the Leuser Ecosystem will occur in the area with threats to local populations and sites. Different conservation strategies should be performed in the areas likely to present different threats toward mammal species. Habitat restoration and long-term population monitoring are needed to support conservation in this mega biodiversity region. |

Abstract | Links | BibTeX | Tags: anthropogenic disturbances, biodiversity, herpetofauna, Nantu Wildlife Sanctuary, Sulawesi @article{Kusrini2020, The Nantu Forest in Gorontalo Province, Sulawesi, Indonesia holds one of the few remaining pristine habitats in the island. The reserve is surrounded by human habituation which provide opportunity to study the impact of forest lost on biodversity. In addition, data on Nantu mostly focused on big mammals, as there is no previous herpetofauna survey at the area. Sampling of amphibian and reptile was conducted in June 2013 and in May–June 2014 using Visual Encounter Survey method, glue traps and transect sampling in seven different sites at the eastern part of Nantu. We categorized four habitat types based on human disturbances: high disturbed habitat (HDH), moderate disturbed habitat (MDH), low disturbed habitat (LDH) and pristine habitat (PH). A total of 680 individual amphibians (4 families; 17 species) and 119 individual reptiles (9 families; 29 species) were recorded. Species richness and species composition for amphibians and reptiles differs according to the level of human disturbances. Low level disturbances habitat demonstrated the highest diversity of amphibians and reptiles, whereas as expected, high distubed habitat showed the lowest diversity. Anthropogenic pressures in forest will decrease species richness of amphibian and reptiles. Although most amphibian and reptiles will be able to persist in low disturbances habitat, forest-dependent species will be lost when pristine forests are disturbed. |
