Abstract. Lestari AD, Patria MP. 2025. Estimation of carbon stock and economic valuation of mangrove ecosystem in Ngurah Rai Grand Forest Park, Bali, Indonesia. Biodiversitas 26: 2821-2831. Ngurah Rai Grand Forest Park (GFP), Bali, is considered one of Indonesia’s successful examples of mangrove forest restoration, yet it remains ecologically vulnerable due to persistent anthropogenic pressures. An essential component of mangrove restoration is ecosystem monitoring, which includes both ecological assessments and economic valuation to determine carbon sequestration potential. The mangrove ecosystem in Ngurah Rai GFP provides tangible ecological, physical, and economic benefits to the local community, necessitating comprehensive evaluation to support long-term sustainability. This study aimed to assess the economic value of mangroves and estimate their carbon sequestration potential to better understand their contribution to climate change mitigation. Fieldwork was conducted from March to September 2024. Carbon sequestration was estimated using a non-destructive allometric model to measure mangrove tree biomass and sediment carbon content was analyzed using the Loss on Ignition (LOI) method. The Total Economic Value (TEV) of the mangrove ecosystem was estimated by incorporating direct use values (ecotourism, fisheries, and processed mangrove products); indirect use values (carbon sequestration, coastal protection, and ecological functions such as spawning, feeding, and nursery grounds); option values (biodiversity benefits); existence values (willingness to pay); and bequest values. The results revealed that the average carbon sequestration potential in Ngurah Rai GFP is 1,742.08 tons CO?/ha/year. The Direct Use Value (DUV) was IDR 675,615,035,500/year; the Indirect Use Value (IUV) was IDR 862,383,525,618/year; and the Existence Value (EV) was IDR 185,158,788,000/year. The Option Value (OV), derived from biodiversity benefits, was IDR 722,958,245/year, while the Bequest Value was estimated at IDR 67,561,503,550/year. The total TEV of the mangrove ecosystem in Ngurah Rai GFP was IDR 1,791,441,810,913/year, equivalent to approximately USD 107,918,182/year.

Abstract. Pradana DH, Winarni NL, Patria MP, Yasman. 2025. Influence of forest configuration and bird exclusion on insect herbivory in Indonesian oil palm smallholdings. Biodiversitas 26: 4640-4646. The insect pest control services provided by birds may help address one biological challenge in oil palm plantations. Previous studies suggest that understory birds contribute to this ecosystem service and that forest configuration may influence their effectiveness. We investigated whether understory birds reduce insect pests and whether forest configuration affects their pest control services in six oil palm smallholdings in Indonesia. Understory birds were surveyed using the point count method at 0-200 m from adjacent forests. Herbivory rates, used as a proxy for insect pest activity, were assessed through a bird enclosure experiment. The indirect bird effect on herbivory rate was also evaluated using this experiment. We used binomial Generalized Linear Mixed Model (GLMM) to analyze the effects of understory bird abundance and forest configuration on herbivory rates. Results showed the herbivory rate ranged from 0.01 to 0.84 mm². A weak negative relationship between understory bird abundance and herbivory in control treatments (z: -1.65, n: 12, p-value<0.1) was found, suggesting a limited pest control effect. However, no significant influence of forest distance or remnant size on herbivory rates was observed. Functional trait analysis revealed that the bird community was dominated by gleaners, omnivores, and large-bodied species, which are typically associated with insectivores. The absence of strong effects may be linked to small forest remnant sizes, low pest abundance, and the structural limitations of smallholder oil palm understory that limit the use of this habitat by forest understory birds. While understory birds show some potential for insect pest control, their effectiveness appears constrained under current conditions. It is clear that urgent action is needed. Habitat enhancement through reforestation and vegetation management to increase habitat connectivity, and may be necessary to support more robust pest control by bird communities in oil palm landscapes.

Abstract. Ainy NS, Sjahfirdi L, Petala MP, Harinaldi. 2026. Diversity of freshwater fish in Jabodetabek (rivers and lakes), Indonesia. Biodiversitas 27 (5): d270518. https://doi.org/10.13057/biodiv/d270518. In the Jabodetabek (Jakarta, Bogor, Depok, Tangerang and Bekasi) metropolitan area of Indonesia, this study assessed the structure of freshwater fish communities in interconnected river and lake ecosystems. The focus was on diversity, native-alien composition, and spatial homogenization along upstream-downstream river gradients and inlet-outlet lake zonation. From August to December 2024, fish were collected from three rivers (Ciliwung, Cisadane, and Cileungsi) and three lakes (Tonjong, Tunggilis, and Suradita) using standardized plots and various types of fishing gear. The data were then analyzed for species richness, abundance, diversity, dominance, PERMANOVA, and beta dispersion. Rivers had more species (38) and individuals (2,471) than lakes (27 species and 1,375 individuals), but they also had a higher proportion of alien fish (64.90%) than lakes (50.20%). Oreochromis niloticus and Pterygoplichthys pardalis were the dominant invasive species in rivers, especially in the middle and downstream sections. Oreochromis niloticus and Amphilophus labiatus were the dominant invasive species in lakes, particularly in inlet zones and disturbed areas. Lakes showed more pronounced cross-zone biotic homogenization, whereas rivers exhibited higher spatial turnover. However, some degraded areas also showed signs of homogenization. The findings suggest that biological invasions are reducing the complexity of Jabodetabek’s freshwater ecosystems and pushing native species into less disturbed habitats. To reduce the risk of reinvasion and protect freshwater biodiversity, management should focus on controlling the most widespread invasive species, preventing new introductions, restoring habitats, and protecting existing native fish refuges.

Abstract

Freshwater ecosystems, particularly small lakes, play a crucial role in maintaining biodiversity and supporting essential ecological functions, yet they are highly vulnerable to environmental disturbances. Small lakes are increasingly exposed to anthropogenic pressures such as land use change, nutrient enrichment, and declining water quality, making biological assessment essential for detecting ecosystem degradation. This study aimed to identify segment level patterns of fish diversity, evenness, and dominance during the seasonal transition period and to determine whether these patterns can distinguish relatively balanced ecological zones from priority stress zones for ecosystem management. An ecologically based quantitative descriptive approach was applied using spatial zoning of inlet, middle, and outlet segments. Fish assemblages were assessed using the Shannon–Wiener diversity index (H′), Evenness (E), and Simpson’s dominance index (D). The results revealed clear spatial variation in community structure among sampling segments. Some systems exhibited strong internal ecological gradients characterized by decreasing diversity and increasing dominance toward downstream segments, whereas others showed more transitional or relatively uniform patterns. Community composition analysis indicated assemblage compression and potential biotic homogenization driven by a limited number of dominant taxa. Exploratory analyses further suggested that higher alkalinity, hardness, and chlorine levels were associated with lower diversity and greater dominance. These findings demonstrate that fish community indices provide effective biological indicators of ecosystem condition and can support spatially targeted monitoring, conservation, and management of small freshwater ecosystems. The study also highlights the importance of incorporating spatially explicit community assessments into ecosystem health evaluation frameworks.

Abstract

In recent years, fossil fuel usage and industrial activities have significantly increased, leading to higher greenhouse gas emissions and impacting global temperature, contributing to global warming and climate change. The carbon footprint measures these emissions through carbon flux rates, influenced by climate conditions, soil and water uptake, organic matter, and microbial activities. The experiment used a gas analyzer and gas chromatograph to measure samples under three conditions. The highest average flux rate was in fully enclosed vegetation (4.04 g CO2/m²/day), followed by not enclosed vegetation (4.01 g CO2/m²/day), and the lowest was 3.91 g CO2/m²/day. Results indicate that vegetation and urban parks reduce CO2 emission fluxes, with each area's vegetation state affecting soil and air temperature, pH content, and soil moisture. However, many aspects such as soil type and climate cognition can influence fluctuation of carbon fluxes in each condition.
