The characteristics of macrobenthic community structure can accurately indicate the ecological health aquatic environments. To elucidate spatiotemporal responses communities and environmental factors in reservoirs, this study investigated macrobenthos parameters Yinghu Lake during spring (May), summer (August), autumn (November). results showed that trophic level index (TLI), total nitrogen (TN) phosphorus (TP) were significantly higher pH was lower (P < 0.05) at developed sites (DS) than undeveloped (UDS). survey identified 32 species representing 3 phylums 5 orders. PERMANOVA analyses differed between regions, Limnodrilus hoffmeisteri from gathering collectors (20.47%) Corbicula fluminea filtering (7.82%) primary driving differences. two-way ANOVA indicated richness, Margalef (D), functional feeding group (FFG-D) 0.05).

In summary, variations quality reservoir influenced natural conditions anthropogenic disturbances. This provides valuable insights into dynamics contributes a more comprehensive understanding role biodiversity maintaining stability large ecosystems.

As an emerging global issue in coastal marine ecosystems, eutrophication may lead to profound ecological consequences or disasters. Six locations Xiangshan Bay were sampled during 2012-2022 along the gradient from innermost bay with most outer least eutrophication. A trait-based method was adopted explore effects of on macrobenthic communities. The results showed that community composition is mostly characterized by deposit feeders and predators small (1-3 cm) large (> 10 body sizes, classified as indifferent tolerant species (AMBI groups), (feeding mode), a preference for free living lifestyle. RLQ fourth-corner analyses further confirmed there negative correlation between abundance organisms (< 1 nitrate concentration.

The taxonomic and functional diversities of macroinvertebrates are a critical indicator ecosystem health. This study focuses on the assemblage structure in Ibrahimia Canal, Egypt. They were compared across two different substrate habitats: sediment-associated macrophytes-associated habitats. Significant variations biological trait community composition habitats recorded, with high taxa abundance sediment increased diversity macrophyte substrate. In substrates, burrow dweller collector-filterer main characteristics, while tube collector-gatherer traits macrophytes indices tended to increase from substrate; however, there was an Rao's quadratic entropy index (RaoQ) for habitat. Redundancy analyses explained association between environmental factors macroinvertebrate traits. Total suspended solids, dissolved oxygen, chemical demand phosphate key drivers macroinvertebrates. Integration approaches is recommended give insight into explaining managing freshwater ecosystem.

Abstract Tidal flats are valuable ecosystems that depend on complex biogeomorphic processes between organisms and sediment transport. Climate change has led to a rise in extreme weather events, such as storms. This, turn, increased dynamics created risks for the benthic communities inhabiting tidal flats. However, replicating disturbances caused by is difficult. To overcome this, we used plow rake enhance natural currents wave conditions simulate intensified dynamics. The raking disturbance was repeated two intertidal zones with different inundation frequencies wind fetch levels increasing frequency of storm impact sediments due climate change. We compared measurements macrofauna plots were raked control only influenced hydrodynamics. Results showed flat experienced erosion 10–20 mm after six times biweekly treatments, depending site‐specific hydrodynamic conditions. Sediment served helpful tool monitoring species distribution regarding mobility traits: high dynamic exposed sites inhabited mobile species, while low sheltered characterized less‐mobile species. Moreover, treatment decreased abundance immobile traits, yet composition did not experience significant Overall, present findings indicate at higher risk declining under than areas macrofauna.

Numerous community indices have been developed to quantify the various aspects of communities. However, including functional less focused on. Here, we examined how composition varies in response environment and discovered relationship between taxonomic diversity while considering environment. Macroinvertebrate communities were collected from 20 reservoirs South Korea. To characterize diversity, traits four categories considered: generation per year, adult lifespan, size, feeding groups. Based on their composition, classified using hierarchical cluster analysis. Physicochemical land use variables varied considerably clusters. Non-metric multidimensional scaling indicated differences clusters terms structure, environmental variables. A self-organizing map was used categorize traits, network association analysis unravel relationships traits. Our results support characteristics species’ survival strategies such as r- K-selection. Functional richness exhibited a with diversity. findings suggest that different types could play complementary roles identifying biodiversity. should prove useful developing new criteria for assessing freshwater ecosystem health, well evaluating predicting future alteration benthic macroinvertebrate facing anthropogenic disturbances.
