    Abstract Lake Keliling and Lake Baru are oxbow lakes located along the Kapuas River, the largest river in West Kalimantan. This study aimed to analyze the variations in water temperature and dissolved oxygen (DO), and their relationship with fluctuations in the main river during the dry and wet seasons. We measured water temperature and DO parameters at Lake Keliling and Lake Baru in February and September 2023 for wet and dry seasons, respectively. Moreover, we installed a camera for monitoring the river water level fluctuations at both locations. In addition, we obtained the secondary data for water level and water quality data (2021 – 2022 and 2018 – 2022, respectively) close to both sites. The result showed during the wet season, the vertical distribution pattern of DO in Lake Keliling and Lake Baru showed a similar pattern to temperature. Anoxic conditions in Lake Keliling during the rainy season were observed at a depth of 2 meters, whereas in Lake Baru, these conditions were found at depths of 6 to 8 meters. During the dry season, the depth of the anoxic water column in Lake Keliling remained at 2 meters, while in Lake Baru, the anoxic layer shifted to a shallower depth of approximately 1.8 meters, except at Station Baru 3. This indicates the potential for sediments to store heat at shallow depths. It could be explained that the variability of water temperature and DO parameters, was likely various changes related to the water level conditions (dry and wet seasons).

    Abstract Kapuas River in West Kalimantan with over 1,143 km is the largest river in Indonesia. It serves as a main refuge for high potential biodiversity. Oxbow lakes along the Kapuas River are of high ecological essential due to the number and the diversity of habitats they provide. In addition, oxbow lakes are critical components of the floodplain systems of lowland rivers. The objective of this study was to explore the diversity of oxbow lakes and their connectivity to the main river. We conducted fieldwork to measure water quality and ecological components at 12 oxbow lakes along the Kapuas River and two lakes in the Sentarum complex in January - February 2020. We measured the environmental parameters including water depth, water temperature, Secchi/transparency, pH, dissolved oxygen concentration, chlorophyll-a concentration, total nitrogen, and total phosphorus concentrations. Aquatic biota, including phytoplankton and zooplankton community structures, were also observed at 12 oxbow lakes along the Kapuas River and two lakes in the Sentraum complex. The sampling points represented both permanent and non-permanent connectivity of the oxbow lakes to the main river. The result indicates the variability of environmental characteristics between the lakes, based on water quality and biota analysis; for example, water acidity, as indicated by pH, was likely to seem like the main variable determining the oxbow lake biota. Also, the habitat connectivity of oxbow lakes to the main river has significantly influenced the biotic composition.

    We investigated a method to estimate the migration history of terrestrial plants (seeds) to freshwater fish, marine fish, and birds, by using multi-elemental (carbon, nitrogen, sulfur, hydrogen, and oxygen) isotope ratio analysis and the carbon and nitrogen isotope ratio analysis of individual amino acids as research methods, and by utilizing eye lens and other parts as sites for storing migration history. The results showed the effectiveness of this method in areas where isotopic maps (Isoscapes) can be obtained. The multi-elemental isoscapes are expected for the enhancement of the further development of this research.

    Diverse types of tropical rainforests occur in Borneo, which has weathered soils derived from old geological substates. We investigated if the occurrence of such diverse forests could be explained by the asymmetrical relationship of N versus P cycles. We studied canopy tree communities, dithionite-extractable Fe, and soil N and P concentrations in study plots placed in Borneo. There was a wide gradient of Fe oxide concentration among the study plots, and soil nutrient availability shifted from relative P deficiency to relative N deficiency with increasing magnitude of Fe leaching. Tree community composition shifted continuously along this soil gradient. This result suggested that dominant trees were successively displaced with each other from P-deficiency adapted to N-deficiency adapted species. Diverse forests are formed along a soil nutrient gradient with N versus P deficiencies as two endmembers through plant-soil feedbacks.

    In order to elucidate the ecological function of saturated interstitial zone underneath the riverbed (hyporheic zone) in transferring resource to river-riparian food web, the following four major findings were obtained. First, the food web in the hyporheic zone was visualized with the identification of aquatic insect species adapted to hyporheic habitat (hyporheic species). Second, the amount of resource provided from the hyporheic zone to the riparian zone was estimated by focusing on hyporheic species. Third, the responses of macroinvertebrate community including hyporheic species to floods and nutrient pollution in surface water were measured. Overall, this research project comprehensively provided techniques and a conceptual scheme useful in the assessment of river-riparian environmental heath based on hyporheic species in particular by focusing on their adults that are easier to catch in comparison with their aquatic larvae in physically concealed hyporheic zone.
