Abstract

Background: Mangrove ecosystems are crucial for maintaining biodiversity, including crab communities, which are vital to the stability of these ecosystems. Crabs contribute to nutrient cycling and the food web, reinforcing the overall ecological health of coastal habitats. This study focuses on the crab communities in the mangrove area of Tabongo Village, Dulupi District, Boalemo Regency, examining how environmental conditions affect their distribution and diversity. Methods: The research involved surveys at three stations representing different mangrove vegetation conditions. Crab species were identified and their diversity and abundance recorded. Environmental parameters, such as temperature, salinity, and pH, were measured, and the diversity index (H') was calculated to assess species diversity and the relationship between crab communities  and environmental factors. Findings: A total of 11 crab species from 4 families were identified, including Uca (Paraleptuca) annulipes and Ocypode ceratophthalmus. The diversity index ranged from 1.3 to 1.6, indicating moderate diversity. Environmental conditions, with temperatures between 32–34 °C, salinity from 13–19 ppt, and pH from 6.5 to 7, were conducive to crab survival. Station III, with healthier mangrove vegetation, supported greater crab diversity and abundance compared to degraded stations. Conclusion: The study highlights the crucial role of healthy mangrove ecosystems in sustaining crab biodiversity and ecosystem stability. It underscores the importance of mangrove conservation for maintaining biodiversity and protecting coastal ecosystems from degradation. Novelty/Originality of this article: By linking the health of mangrove ecosystems to crab diversity and abundance, it emphasizes the direct impact of environmental factors on crab populations. The findings highlight the importance of mangrove conservation not only for species richness but also for maintaining the ecological balance in coastal ecosystems, offering valuable data for future biodiversity management and conservation efforts.

Abstract

Background: This study aims to determine the quality of water channels close to rice fields and houses that produce domestic and agricultural waste based on heavy metal contamination. Method: Water sampling was carried out directly at the research location and tested at the UPTD Regional Health Laboratory of Gorontalo Province. The sampling points amounted to three points, namely station I, station II, and station III. The water quality parameters analyzed included heavy metals (Cd, Hg, Fe), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), and temperature. Results: The results of Cd heavy metal concentrations at each point were station I (0 mg/L), station II (0 mg/L), and station III (0 mg/L). Heavy metal Hg was recorded at station I (0.0038 mg/L), station II (0.00185 mg/L), and station III (0 mg/L). Fe heavy metal concentrations were station I (1.20685 mg/L), station II (1.0082 mg/L), and station III (0.4 mg/L). The pH value in Tamalate canal water remained stable at around 7, with station I (7.3), station II (7.4), and station III (7.3). The DO values were station I (82.7 mg/L), station II (85.1 mg/L), and station III (81.7 mg/L). The BOD values were station I (55.35 mg/L), station II (51.85 mg/L), and station III (57.05 mg/L). The COD values were station I (110.5 mg/L), station II (109.5 mg/L), and station III (119.5 mg/L). The temperature measurements were station I (30.95℃), station II (29.35℃), and station III (30.2℃). Conclusion: The distribution of heavy metals in canal water is quite varied due to the influence of environmental conditions and activities around the Tamalate canal, resulting in uneven distribution. Novelty/Originality of this article: This study provides a detailed assessment of heavy metal contamination using multiple water quality indicators. It highlights the influence of surrounding land use, including domestic and agricultural activities, on metal distribution and overall water quality.

Abstract

Background: The Maleo (Macrocephalon maleo) is a Sulawesi-endemic bird with high conservation concern due to habitat degradation and population decline. The Panua Nature Reserve is a key Maleo habitat in Gorontalo Province, yet lacks updated data on habitat use and distribution patterns. This study aims to analyze Maleo presence in nesting grounds, evaluate habitat utilization, predict its distribution, and provide conservation recommendations. Methods: The research used direct surveys via camera traps and spatial modeling using the Maximum Entropy (MaxEnt) algorithm. Data were collected over five months, and analysis included the Relative Abundance Index (RAI) and occupancy modeling to assess habitat suitability and species detection. Finding: Maleo nesting pairs increased by 68.52% from 2022 to 2023. The species exhibited bimodal daily activity (peaks at 06:00–09:00 and 16:00–18:00), with habitat preference for geothermal zones and coastal forests. The RAI was 9.33%, and occupancy rate was estimated at 55%. MaxEnt modeling revealed 7,544.78 ha of highly suitable habitat, concentrated in grids N10, J13, K14, and M09, with an AUC of 0.826, indicating high predictive accuracy. Conclusion: Maleo birds in Panua Nature Reserve are showing a positive nesting trend. However, habitat fragmentation and human activities continue to threaten their sustainability. Strategic management is needed to maintain habitat integrity and support species conservation. Novelty/Originality of this article: This study integrates field-based camera trap data with predictive spatial modeling to provide a comprehensive habitat suitability analysis for the endangered Maleo in Panua Nature Reserve—an approach not yet applied in this location. The findings offer actionable conservation insights and prioritize critical zones for protection.
