Abstract

 Setyawan AD, Supriatna J, Nisyawati, Sutarno, Sugiyarto, Nursamsi I. 2018. Predicting impacts of future climate change on the distribution of the widespread selaginellas (Selaginella ciliaris and S. plana) in Southeast Asia. Biodiversitas 19: 1960-1977. The current global climate is moving towards dangerous and unprecedented conditions that have been seen as a potentially devastating threat to the environment and all living things.  Selaginella is a fern-allies that needs water as a medium for fertilization, hence its distribution is presumed to be affected by climate change. In Southeast Asia (SEA), there are two widely distributed selaginellas, namely Selaginella ciliaris and S. plana. S. ciliaris is a small herb (up to 4 cm), annual, abundant during the rainy season, and found in the middle-high plains, whereas S. plana is a stout large herb (up to 80 cm), perennial, and mainly found in the lowlands. The purpose of this study was to determine the potential niche distribution of S. ciliaris and S. plana under current climatic conditions, and to predict its future distribution under the impacts of climate change. We used Maxent software along with bioclimatic, edaphic, and UV radiation variables to model the potential niche distribution of those two selaginellas under current and future predictions climate conditions. We generated future predictions under four detailed bioclimatic scenarios (i.e., RCP 2.6, RCP 4.5, RCP 6.0, and RCP 8.5) over three times intervals (2030, 2050, 2080). The results showed that future climatic conditions in the SEA had been predicted to significantly disrupt the distribution of suitable habitat of S. ciliaris and S. plana, and alter their geographic distribution patterns. Although some areas were predicted to become suitable habitat in the early period of future climate change, the overall projections show adverse effects of future climate conditions on the suitable habitat distribution of S. ciliaris and S. plana, as estimated losses of suitable habitat will be higher than the gains.

Kusumaningrum EN, Supriatna J, Abinawanto, Bowolaksono A. 2018. Short Communication: Ethnozoology – The perception of Tobelo Dalam tribal community in Saolat Village, East Halmahera, Indonesia towards cuscus (Phalangeridae). Biodiversitas 19: 2140-2146. The complexity of the hard lives of Tobelo Dalam tribal community who live in Saolat village, district South Wasile provokes the high activity of animal poaching in Aketajawe-Lolobata National Park (TNAL) including cuscus hunting for both sale and consumption purposes. The study aimed to describe the traditional knowledge of Tobelo Dalam people in Saolat village in applying the systems of utilization and local conservation knowledge towards cuscus. This study was analyzed by the qualitative method with explorative survey technique, interview, and completing questionnaires. This study used 4 key informants (3 males, 1 female) and 50 adult respondents (25 males and 25 females). The results showed that the average percentage of traditional knowledge owned by males and females were 69.1% and 30.9 %, respectively, so the males had an advantage of knowledge around 38.3 % than females in addressing the traditional knowledge of cuscus. The community of Tobelo Dalam tribe hunts cuscus for four different purposes, i.e., for traditional ceremonies, traditional medicine, cuisine, and sell it for more income to support the economy of family.

Abstract. Dharmayanti N, Supriatna J, Abinawanto, Yasman. 2019. Isolation and partial characterization of Alginate from Sargassum polycystum of Banten, Indonesia. Biodiversitas 20: 1776-1785. The utilization of Sargassum polycystum as an alternative alginate source may reduce the dependence on alginate import as currently alginate demands in Indonesia are 100% supplied from overseas. The purpose of this study was to characterize alginate extracted from Sargassum polycystum obtained from three locations with different ecological characteristics. Isolation of alginate was conducted through partial hydrolysis to separate guluronic acid and mannuronic acid followed by freeze-drying and then the parameters were measured qualitatively and quantitatively using FTIR. The results showed that alginate extracted from Sargassum polycystum collected from Lima Island, Ujung Kulon and Binuangeun were 11.48%, 18.62%, and 5.75%, respectively with the viscosity were 35 cP, 62.50 cP, and 81.33 cP, respectively. The test result of partial hydrolysis of alginate showed that guluronic block (GG) in the alginate polymer of Lima Island, Ujung Kulon and Binuangeun were 67.60%, 59.00%, and 41.40%, respectively. These relate to the nature of the gel formed. The alginate from Lima Island tends to be more rigid and less flexible than that from Ujung Kulon and Binuangeun. The findings of this study suggest that there are differences in the concentration of the components of mannuronate and guluronate of Sargassum polycystum across different locations in Banten, Indonesia.

Abstract. Simbiak M, Supriatna J, Walujo EB, Nisyawati. 2019. Review: Current status of ethnobiological studies in Merauke, Papua, Indonesia: A perspective of biological-cultural diversity conservation. Biodiversitas 20: 3455-3466. Ethnobiology is a scientific study that examines the dynamic relationship between humans, biota and the environment. In this dynamic relationship, holistic notions that integrate humans and their cultural and biological diversity give more responsibility to ethnobiological studies. This research approach stimulates insights to integrate scientific research with awareness of political and ecological issues, loss of biological resources, including indigenous peoples' struggles over land and resources, identity degradation due to loss of culture and language. Ethnobiological studies undertaken in Merauke, Papua between 2000 and 2017 were reviewed from the perspective of biological-cultural diversity conservation. The aims and results of such published ethnobiological studies were analyzed and we found the failure of such studies in accounting for linguistic diversity in the region while documenting ethnobiological knowledge. Most of such ethnobiological studies were oriented on the topic of economic botany, focusing on recording the potential uses of plants utilized by each ethnic group in the Marind language-culture area of Merauke District, especially those belonging to the domain of medicinal plants. Some studies also used artificial community terminology to treat several ethnic groups as uniform and did not mention what language used for the local names of plants in their reports. Future ethnobiological research in the area would benefit from: (i) adopting a cognitive ethnobiology orientation; (ii) applying appropriate ethnolinguistics standards of research to document the languages; and (iii) using a quantitative approach to analyze the distribution of ethnobiological knowledge within the communities studied. The latter approach is especially important given the extreme and rapid changes of the environment in this region.

Abstract. Setyawan AD, Supriatna J, Nisyawati, Nursamsi I, Sutarno, Sugiyarto, Sunarto, Pradan P, Budiharta S, Pitoyo A, Suhardono S, Setyono P, Indrawan M. 2020. Predicting potential impacts of climate change on the geographical distribution of mountainous selaginellas in Java, Indonesia. Biodiversitas 21: 4866-4877. Selaginella is a genus of non-flowering plant that requires water as a medium for fertilization, as such, it prefers mountainous areas with high level of humidity. Such unique ecosystem of Selaginella is available in some parts of Java Island, Indonesia, especially in highland areas with altitude of more than 1,000 meters above sea level. However, most mountainous areas in Java are likely to be affected by climate change due to global warming, threatening the habitat and sustainability of Selaginella. This study aimed to investigate the impacts of climate change on the geographical distribution of Selaginella opaca Warb. and Selaginella remotifolia Spring. In doing so, we predicted the suitable habitats of both species using Species Distribution Model (SDM) tool of MaxEnt under present climate conditions and future conditions under four climate change scenarios. Species occurrence data were obtained from fieldworks conducted in 2007-2014 across Java Island (283 points: 144 and 139 points for S. opaca and S. remotifolia, respectively) and combined with secondary data from Global Biodiversity Information Facility (GBIF) (52 points: 35 and 17 points for S. opaca and S. remotifolia, respectively), and this dataset was used to model present geographical distribution using environmental and bioclimatic variables. Then, future distribution was predicted under four climate change scenarios: i.e. RCP (Representative Carbon Pathways) 2.6, RCP 4.5, RCP 6.0, and RCP 8.5 in three different time periods (2030, 2050, and 2080). The results of the models showed that the extent of suitable habitats of S. opaca and S. remotifolia will be reduced between 1.8-11.4% due to changes in climatic condition, and in the areas with high level of habitat suitability, including Mount Sumbing, Mount Sindoro and Mount Dieng (Dieng Plateau), the reduction can reach up to 60%. This study adds another context of evidence to understand the potential impacts of climate change on biodiversity, especially on climate-sensitive species, such as Selaginella, in climate-risk regions like mountainous areas of Java Island.

Abstract

Tropical rainforests are among the most important ecosystems on earth. After Brazil, Indonesia has the second largest tropical forest area in the world. Since the 1970s, Indonesia’s forests have decreased from covering 87% to 50% of its land area. With the ever increasing pressures from economic and human development it appears likely that much of the biodiversity and ecosystem services provided by forest in Indonesia will only remain in conservation areas.  National parks currently cover around 60% or 16 Mha of the total area of protected areas in Indonesia. Between 2012 and 2017, 42 terrestrial national parks in Indonesia lost 1.07% of their total forest cover. However, primary forest cover increased by 0.07%. National parks in the Jawa Bali bioregion, through their natural mountainous conditions and ecosystem services to the surrounding areas, as well as better management inputs, have contributed to the increase of primary forest covers and keeping total forest loss relatively low in Indonesia’s national parks.

Projecting expansion range of Selaginella zollingeriana in the Indonesian archipelago under future climate conditions. Biodiversitas 22: 2088-2103. The expansion of plant species to outside areas of its original localities has attracted great interest in theoretical ecology. The scientific curiosity of such phenomenon is even deeper when the geographical expansion is confined by natural boundaries and affected by environmental changes, including climates. This study aimed to predict the current suitable habitat niche of Selaginella zollingeriana Spring, a species with original distribution in Java Island, and to project its potential suitable niche in the Indonesian archipelago accounting for future climate conditions. In doing so, we applied the Ecological Niche Modelings (ENMs) using MaxEnt algorithm by employing 30 presence data of S. zollingeriana and twelve enviro-climatic variables. The model predicted around 17.22% (22,095 km2) of the Java Island area is potentially suitable for current habitat niche of S. zollingeriana, consisting of 10.93% (14,028 km2), 4.75% (6,097 km2), and 1.54% (1,970 km2) of low, medium, and high suitability areas, respectively. Under future scenarios, the model predicted the possibility of species expansion into the other four big islands (i.e., Sumatera, Borneo, Sulawesi, and Papua). Nonetheless, the model also predicted a declining trend of the availability of suitable niches wherein from 2030 to 2080 the modeled niche declined about 58% and 59% under the most optimistic and most pessimistic climate change projections, respectively. While this study provides a primary example in predicting species expansion in tropical archipelago, similar studies in a range of contexts (e.g., species, region) are recommended to add more evidence to strengthen the theoretical ground of expansion ecology under climate changes.

Abstract. Setyawan AD, Supriatna J, Nisyawati, Nursamsi I, Sutarno, Sugiyarto, Sunarto, Pradan P, Budiharta S, Pitoyo A, Suhardono S, Setyono P, Indrawan M. 2020. Anticipated climate changes reveal shifting in habitat suitability of high-altitude selaginellas in Java, Indonesia. Biodiversitas 21: 5482-5497. High-altitude ecosystems with humid and cool climate are the preferred habitat for some Selaginella species (selaginellas). Such habitats are available in Java, Indonesia, which also has fertile soils with rich mineral contents resulted from volcanic activities. However, the high-altitude ecosystems in Java are threatened by various anthropogenic activities as well as changes in climate conditions, potentially affecting some Selaginella species. This study aimed to investigate the shift in suitable habitat of four species of high-altitude Selaginella spp. (Selaginella involvens, S. opaca, S. ornata, and S. remotifolia) in Java Island under current and future climate conditions predicted by several representative greenhouse gas concentration pathways. Presence data of Selaginella localities were collected from field survey between 2007 and 2014 across the island, as well as occurrence points from the Global Biodiversity Information Facility database. A total of 1,721 occurrence points data along with environmental and climate data were used to develop species distribution models using MaxEnt. Future habitat distributions were projected under four climate scenarios to see the shift in suitable habitat and altitudinal ranges. The results showed that the distribution of the four high-altitude Selaginella species are strongly influenced by altitude, annual average temperature, and annual rainfall. In the present time, 37.32% (48,974 km2) of the area of Java has been predicted to be suitable for high-altitude Selaginella. Under the optimistic climate scenario (RCP 2.6), the highly suitable area will likely to decrease by almost 35% in the year 2080, whereas the medium and low suitable areas will reduce by about 37.2% and 18.3%, respectively. Under the pessimistic scenario (RCP 8.5), about 21.2% of low suitable areas will be lost in 2080, whereas the medium and highly suitable areas are predicted to decrease by around 38.1% and 33.4%, respectively. Under the pessimistic scenario, there will be upward shift by 51.1 m in the year 2030 from the current’s mean altitude and will shift by almost 150 m in the year 2080. The maximum altitude of predicted suitable habitat is also predicted to increase to reach almost 3500 m asl in the year 2080. The results of this study imply that habitat shift of four high-altitude Selaginella species varies depending on the scenario, but in all cases, the losses are greater than gains.

Abstract. Pin TG, Supriatna J, Takarina ND, Tambunan RP. 2021. Mangrove diversity and suitability assessments for ecotourism in Cimalaya Wetan Coast, Karawang District, Indonesia. Biodiversitas 22: 803-810. Mangrove forest has been a popular ecotourism destination recently. One of the methods to assess the mangrove potential for ecotourism is by using Tourism Suitability Index (TSI). This study was aimed to assess the ecotourism potentials of mangrove forest sizing of 56.43 hectares in Cilamaya Wetan Sub-district, Karawang District, West Java Province, Indonesia using the TSI method. To assess the mangrove variables, 10 sampling stations have been selected across the coast. In each station, 10 sample plots sizing of 10 m x 10 m have been established. The TSI was measured based on mangrove variables including species diversity, density, and thickness. We recorded six mangrove plant species belonging to three plant families. Avicennia alba, Bruguiera gymnorrhiza and Rhizophora stylosa, were common species found along the coast. Shannon-Wiener index (H’) showed that the west and east parts of Cimalaya Wetan had high mangrove diversity compared to the central part. The TSI analysis showed that the most suitable areas of mangrove forests for ecotourism were 32.18 hectares (57.11% of the total area), mainly located in the east part of the coast. Moreover, the moderate and least suitable areas were 19.12 hectares (33.94%) and 5.03 hectares (8.93%), respectively, and located in the central part of the coast.

Abstract. Firdaus N, Supriatna, Supriatna J. 2022. Ecosystem services research trends in Indonesia: a bibliometric analysis. Biodiversitas 23: 1105-1117. Among the world's mega-biodiversity countries in the tropics, Indonesia has experienced the most severe deforestation in recent decades. It is alarming that the rate is potentially disrupting the future provision of ecosystem services. On the other hand, there is a paucity of research on ecosystem services in Indonesia, and its current state is unknown. This study provided an overview of ecosystem services research trends in Indonesia from 1998 to 2020 using bibliometric and science mapping analysis of 298 published works from the Scopus database. Since 2013, publications on the topic have increased and grown exponentially, with environmental science dominating the subjects, followed by agriculture and biology, and the social sciences. Biodiversitas and Ecosystem Services are the most prolific journals for publishing results, while Science and Ecological Economics have the most citations. Being the most productive in publications, Indonesia and the United States are also engaged the most in research collaborations. Ecosystem services research in Indonesia is closely linked to biodiversity, deforestation, and oil palm. Furthermore, oil palm, sustainability, and land-use change are promising topics to address in the coming years. This study suggests that the dynamics of ecosystem services research in Indonesia call for further developments in improving the quality of impactful research through interdisciplinary approaches, international collaboration, and the engagement of diverse stakeholders and policy-makers related to the field, to increase the benefits of sustainable ecosystem services in the future.
