Plastics in aquatic ecosystems rapidly undergo biofouling, giving rise to a new ecosystem on their surface, the 'plastisphere.' Few studies quantify impact of plastics and associated community traits from biodiversity functional metabolic function. It has been suspected that impacts may depend its state but comparative responses are rare published literature. We quantified algal biomass, bacterial (16S 18S rRNA), growing surface different plastic polymers incubated within rivers Lower Mekong...
Establishing reference conditions in rivers is important to understand environmental change and protect ecosystem integrity. Ranked third globally for fish biodiversity, the Mekong River has world’s largest inland fishery providing livelihoods, food security, protein local population. It therefore of paramount importance maintain water quality biotic integrity this ecosystem. We analyzed land use impacts on constituents (TSS, TN, TP, DO, NO3−, NH4+, PO43−) Lower Basin. then used a best-model...
The Mekong River is one of the world’s largest rivers, unparalleled in terms its biodiversity and ecosystem services. As other regions, sufficient water quality required to support diverse organisms, habitats, ecosystems, but region, has not been well studied. Based on biological physical-chemical data collected over last two decades, we evaluated spatial-temporal Lower Basin (LMB) using biotic abiotic assessment metrics. We found that during 2000s, LMB was unpolluted, with “very good”...
Tonle Sap lake-river floodplain ecosystem (TSE) is one of the world’s most productive freshwater systems. Changes in hydrology, climate, population density, and land use influence water quality this system. We investigated long term dynamics (22 years) space time identified potential changes nutrient limitation based on ratios inorganic nitrogen phosphorus. Water was assessed at five sites highlighting wet dry seasons. Predictors included watershed use, population, level. Most parameters...
