Aggregation and co-occurrence patterns of microbial communities are the key scientific issues in lake ecology. To explore mechanisms ecological assembly community succession this unique habitat, 16 samples were collected from eight sites Wuliangsuhai Lake. Second-generation DNA sequencing was applied to reveal spatial dynamics bacterial structure distribution across two environmental media nutrient-rich shallow grassland elucidate characteristics network. This study also examined effects filtering biological interactions on formation maintenance composition diversity. The results highlight habitat heterogeneity composition, with no discernible latitudinal diversity patterns. causal analysis identified electrical conductivity, pH, total nitrogen, phosphorus as primary factors driving changes water sediment grass-type lakes, TN being driver.

Identifying Critical Land Use Thresholds for Biodiversity Conservation in China’s Lake Ecosystems

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Aquatic biodiversity loss, particularly in rapidly developing nations, continues to raise concerns, prompting urgent debates on reconciling economic growth with environmental preservation through land use planning. While spatial variations aquatic communities along gradients are well-documented, precise ecological thresholds for impacts freshwater lakes remain elusive, hindering sustainable development efforts. This study investigated six representative China between 2019 and 2020, all significantly impacted by anthropogenic activities. We utilized macroinvertebrate as bioindicators employed four categories of metrics─taxonomic diversity, functional pollution tolerance, water quality─to assess their responses local patterns. Macroinvertebrate community composition varied among the studied lakes, pollution-tolerant taxa predominating highly urbanized eutrophic systems. Notably, benthic exhibited greater sensitivity urban (ecological thresholds: 2-10%) compared agricultural (thresholds: 15-40%). The most pronounced were observed within 1-5 km lakeshore, circular buffers yielding more significant effects than fan-shaped buffers, excluding areas. A novel intensity indicator─the ratio nonecological (NEL/EL = area land/area land)─proved effective predicting shifts. Smaller or heavily showed marked changes at NEL/EL ratios 0 0.6, while larger river-connected shifts exceeding 1.5. These findings underscore profound footprint human activities lake ecosystems cover emerging deleterious factor.

The Effects and Mechanisms of pH and Dissolved Oxygen Conditions on the Release of Arsenic at the Sediment–Water Interface in Taihu Lake

Toxics, Год журнала: 2023, Номер 11(11), С. 890 - 890

The pH and dissolved oxygen (DO) conditions are important environmental factors that control the migration of arsenic (As) at sediment-water interface. This study investigates distribution differences reactive iron, manganese, interface under anaerobic aerobic different levels. strong buffering capacity sediment to water results in a shift towards neutral values overlying initial conditions. level DO becomes key factor release As from sediment, with lower environments exhibiting higher quantities rates compared high environments. Under low conditions, combined effects ion exchange reduction lead most significant As, particularly 9.5 formation amorphous ferrous sulfide compounds is contributing increased concentration interstitial water. Therefore, re-migration endogenous shallow lake sediments should consider multiple driving forces.
