As part of the requirement for the Protected Area Credit of the RFS, species or a group of species that can act as indicators of ecosystem health in Bali Barat National Park (BBNP) have to be identified. Butterflies was one of the taxa assessed for this purpose. A biological survey was conducted in Bali Barat National Park during August-September 2015. Butterfly species were surveyed using a modification of Pollard walk methods by recording species while walking along transects. A total of 82 butterfly species were recoded representing the families Papilionidae, Nymphalidae, Pieridae, Lycaenidae and Riodinidae. Forty-one species, 50 %, were from the family Nymphalidae and 21, 25 % from Pieridae. Nymphalidae and Pieridae was found to be correlated to vegetation structures. The selection process for indicator species was based on Indicator Value (IV) developed by Dufrene and Legendre (1...

We have built a flexible, collaborative modeling framework to foster the development of national pathways by local research teams and their integration up to global scale. Local researchers independently customize national models to explore mid-century pathways of the food and land use system transformation in collaboration with stakeholders. An online platform connects the national models, iteratively balances global exports and imports, and aggregates results to the global level. Our results show that actions toward greater sustainability in countries could sum up to 1 Mha net forest gain per year, 950 Mha net gain in the land where natural processes predominate, and an increased CO2 sink of 3.7 GtCO2e yr−1 over the period 2020–2050 compared to current trends, while average food consumption per capita remains...

Twenty-three million years of complex geological history have given rise to a living laboratory for the study of evolution and biodiversity, highly vulnerable to anthropogenic pressures. In the present article, we review the historic and contemporary processes shaping Wallacea's biodiversity and explore ways to conserve its unique ecosystems. Although remoteness has spared many Wallacean islands from the severe overexploitation that characterizes many tropical regions, industrial-scale expansion of agriculture, mining, aquaculture and fisheries is damaging terrestrial and aquatic ecosystems, denuding endemics from communities, and threatening a long-term legacy of impoverished human populations. An impending biodiversity catastrophe demands collaborative actions to improve community-based management, minimize environmental impacts, monitor threatened species, and reduce wildlife trade. Securing a positive future for Wallacea's imperiled ecosystems requires a fundamental shift away from managing marine and terrestrial realms independently.

How can countries satisfy their demands while jointly delivering the required transformative change to achieve global sustainability targets? Here, we present a collaborative approach developed with the FABLE—Food, Agriculture, Biodiversity, Land, and Energy—Consortium to reconcile both global and national elements for developing national food and land-use system pathways. This approach includes three key features: (1) global targets, (2) country-driven multi-objective pathways, and (3) multiple iterations of pathway refinement informed by both national and international impacts. This approach strengthens policy coherence and highlights where greater national and international ambition is needed to achieve global goals (e.g., the SDGs). We discuss how this could be used to support future climate and biodive...

Biological communities may become increasingly similar to or dissimilar from one another via the processes of biotic homogenisation or heterogenisation. A key question is how the conversion of native forests to agriculture may influence these processes by driving changes in the occurrence patterns of restricted-range endemic species versus wide-ranging generalists. We examined biotic homogenisation and heterogenisation in bird communities on the Southeast Asian islands of Borneo, Sulawesi, Seram, Buru, Talaud and Sangihe. Each island is characterised by high levels of avian endemism and unique spatial configuration of forest conversion to agriculture. Forest conversion to agriculture influenced the patterns of biotic homogenisation on five islands. Bird communities became increasingly dissimilar to forest reference communities relative to localised patterns of deforestation. Turnover led to species with larger global range-sizes dominating communities at the expense of island endemics and ecological specialists. Within islands, forest conversion did not result in clear changes to β-diversity, whereas between-island communities became increasingly similar with greater deforestation, implying that patterns of forest conversion profoundly affect biotic homogenisation. Our findings elucidate how continued conversion of forests is causing the replacement of endemic species by a small cohort of shared ubiquitous species with potentially strong negative consequences for ecosystem functioning and resilience. Halting reorganisation of the biosphere via the loss of range-restricted species and spread of wideranged generalists will require improved efforts to reduce the impacts of deforestation, particularly in regions with high endemism.

Illegal trapping to supply the cage-bird trade has led to its near-total extinction, with the global population estimated to number fewer than 100 individuals. We estimated the current range and population size of the species at Baluran National Park, which supports Java’s last known population, and used species distribution modelling to evaluate potential suitability of currently unoccupied areas across the park to identify priorities for management intervention. We estimate that the Black-winged Myna population numbers 179 individuals (95% CI: 111–288; density: 14.3 ± 3.5 individuals km–2) and that its current range is 12.3 km2. Our model indicated that some 72 km2 of the park (30% of total area) has potentially suitable habitat for the species, and we infer that the principal cause for the disparity between its current and potential range is t...

The purpose of this study was to asses the community of Psittacidae which includes the relative abundance, dominance and species composition in three locations with their different representations of habitats and altitudes. Data were collected in May and July 2013 from three locations, namely Lengkong Ra’beng, Dencang Mese and Wae Ndae. The data collection method used is Point Count. As many as 330 individual Psittacidae were found which are included in 4 different species; Tanygnathus megalorynchos, Geoffroyus geoffroyi, Trichoglossus haematodus weberi and Loriculus flosculus. Amongst the four species found, Loriculus flosculus is listed as Flores’s endemic species and Trichoglossus haematodus weberi is listed as Flores’s endemic sub-species. The relative abundance of each species are expressed in encounter rates. The dominance index value of Mbeliling region is at 0....
