abstract = {Voluntary Sustainability Standards (VSS) and certification are promoted to enhance sustainable agricultural practices, but environmental outcomes of cocoa certification remain understudied. We selected 31 Rainforest Alliance (RA) certified and 31 non-certified cocoa plantations in Luwu Timur, Sulawesi, Indonesia, from a previous socioeconomic survey and assessed vegetation structure, soil fertility, as well as bird species richness. Using Wilcoxon Rank Sum tests, GLMMs and NMDS, we did not find certified plantations to have a higher shade tree diversity, shade tree basal area, and soil fertility. Bird species richness was significantly higher in certified plantations (p = 0.03), but the observed effect on bird species richness became statistically insignificant after controlling for elevation and plantation age in the GLMM. Current RA shade criteria are low, and potentially not sufficiently enforced, limiting RA potential to enhance biodiversity habitat. Certified farmers more frequently used improved farming techniques and received training; hence, certification might provide socioeconomic benefits to farmers while we found environmental outcomes of certification to be limited. Further research is needed to draw robust conclusions on VSS potential to enhance sustainable agriculture.

abstract = {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effort and species richness for the herpetofauna of Java and Bali from specimen collections as well as published and unpublished literature sources, and to develop a map of spatial distributions as of 31 December 2017 – the first herpetofaunal atlas for any part of Indonesia.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 = {Indonesia has a large number of primate diversity where a majority of the species are threatened. In addition, climate change is conservation issues that biodiversity may likely face in the future, particularly among primates. Thus, species-distribution modeling was useful for conservation planning. Herein, we present protected areas (PA) recommendations with high nature-conservation importance based on species-richness changes. We performed maximum entropy (Maxent) to retrieve species distribution of 51 primate species across Indonesia. We calculated species-richness change and range shifts to determine the priority of PA for primates under mitigation and worst-case scenarios by 2050. The results suggest that the models have an excellent performance based on seven different metrics. Current primate distributions occupied 65% of terrestrial landscape. However, our results indicate that 30 species of primates in Indonesia are likely to be extinct by 2050. Future primate species richness would be also expected to decline with the alpha diversity ranging from one to four species per 1 km2. Based on our results, we recommend 54 and 27 PA in Indonesia to be considered as the habitat-restoration priority and refugia, respectively. We conclude that species-distribution modeling approach along with the categorical species richness is effectively applicable for assessing primate biodiversity patterns.},
