Abstract

Seasonal and oceanographic variability can influence the movement ecology of migratory seabirds by altering environmental conditions along their migration routes. This study aimed to evaluate the effects of seasonal and oceanographic variability on the timing and spatial patterns of Common Tern (Sterna hirundo) migration in Indonesian waters. A quantitative observational approach was applied using satellite tracking to characterize migration timing, duration, movement speed, and spatial routes across different monsoon periods. Migration records were integrated with sea surface temperature, wind speed and direction, and seasonal conditions, followed by temporal, spatial, correlation, and regression analyses. The results showed that migration during the southeast monsoon was characterized by shorter duration, higher movement speed, and more direct routes, whereas the northwest monsoon was associated with longer duration, lower movement speed, and more dispersed trajectories. Sea surface temperature was associated with migration timing, while wind conditions were related to movement performance. The findings indicate that migration patterns reflect interactions between seasonal marine conditions and behavioral flexibility. Long-term integration of satellite tracking and oceanographic monitoring is therefore important for identifying environmentally sensitive migration periods and supporting adaptive conservation of migratory seabirds in Indonesian waters

Abstract

The dhole (Cuon alpinus) plays an important ecological role as a predator capable of influencing prey populations and maintaining trophic balance in protected ecosystems. This study aimed to analyze predator–prey interaction patterns and evaluate their implications for dhole population dynamics in a national park conservation area. Wildlife monitoring was conducted using camera traps operated continuously for 12 months at strategic locations, including wildlife trails, water sources, and habitat corridors. Independent detections were used to identify dominant potential prey and calculate the Relative Abundance Index (RAI), while predator–prey population dynamics were evaluated using a differential-equation model based on the Lotka–Volterra framework. The results indicated that wild boar, muntjac, and sambar were the dominant potential prey, with temporal variations in prey abundance followed by corresponding changes in dhole activity. Population modeling demonstrated cyclical predator–prey dynamics, suggesting that prey availability may influence dhole population responses. These findings highlight the potential role of dholes in regulating herbivore populations and maintaining trophic stability. Conservation management should therefore integrate predator protection, prey availability, habitat connectivity, and long-term population monitoring to maintain ecosystem balance in national park conservation areas.

Abstract

Introduction: Land tenure conflicts and forest degradation in national forest border areas have become a complex challenge that impacts social stability and environmental sustainability. These conflicts often arise due to uncertainty in land ownership rights, leading to tensions between local communities, the government, and private companies, resulting in environmental damage such as deforestation. Community-Based Forest Management (CBFM) has emerged as a mitigation approach to address these issues by involving local communities in the sustainable management of forests. Research objective: To evaluate the impact of CBFM policies on the well-being of farmers and the conservation of endemic species in national forest border areas. Research method: A mixed-methods approach, combining household income surveys, in-depth interviews, Focus Group Discussions (FGD), and land cover analysis based on GIS. Research results: The CBFM policy has successfully increased farmers' income, particularly through forest-based business diversification, reduced illegal logging, and supported the preservation of endangered endemic species. Additionally, active community participation in this policy has increased compliance with environmental conservation efforts. This study recommends enhancing local community capacity, strengthening inter-agency coordination, and implementing stricter supervision to ensure the sustainability of the CBFM policy. The success of CBFM implementation is expected to be applied more broadly to achieve farmers' welfare and sustainable forest conservation in Indonesia.
