Despite their small size, wetland pan systems play a crucial role as habitats for diverse aquatic biota. Macroinvertebrate diversity across 12 wetlands in relation to geological type (i.e. sandstone, granite, basalt and rhyolite) hydroperiod high, low) protected subtropical national park South Africa was studied. Water temperature, pH, TDS, conductivity, phosphates salinity showed significant differences among hydroperiods, with types being observed water temperature ammonium. Most of the sediment variables were found be hydroperiods types. 5145 macroinvertebrate individuals belonging 41 genera 9 orders identified. Macroinvertebrates during high abundant low hydroperiod. The canonical correspondence analysis explained 35.8% fitted cumulative variation community structure environmental different This study aimed provide better understanding how they are influenced by hydroperiod, this information is it aids providing management options refuge taxa area protection these wetlands.

The Amazonian region comprises a set of ecosystems that play an essential role in stabilizing global climate and regulating carbon water cycles. However, several environmental issues anthropogenic origin threaten stability this region: agribusiness, illegal mining, timber exports, pesticide use, biopiracy, among others. These actions lead to deforestation, soil erosion, fauna biodiversity loss, resource contamination, land conflicts, violence against indigenous peoples, epidemics. present study aims feature the current degradation process faced by biome identify strategic alternatives based on science inhibit minimize its resources. This applied research, systematic review, highlighted complexity, fragility, importance functioning ecosystem. Although activities such as mining agriculture notoriously cause degradation, research focused scenarios degradation. dynamics Amazon associated with human activity change advancement were also described. Ultimately, emphasizes that, given invaluable Amazon’s natural resources for balance food security, threats endanger sustainability. Beyond well-known human-induced impacts forest life, findings highlight need strategies integrate conservation, sustainable management, public policies region’s development. strategies, supported partnerships, include reducing deforestation burning, promoting education, engaging local communities, enforcing policies, conducting continuous monitoring using satellite remote sensing technology.

This study characterized the physical integrity, hydromorphology, and limnology of ten urban streams in Southwestern Amazon. The objective was to investigate how these characteristics covary identify threats health ecosystems. integrity assessed using a Habitat Integrity Index (HII), hydromorphology based on width, depth, flow, substrate type, limnological characterization through 14 physico-chemical parameters during dry rainy seasons. Three were classified as preserved, two intermediate, five degraded. Anthropogenic alterations observed hydromorphological characteristics, especially type across different categories. Limnological analysis revealed that chemical biochemical oxygen demands, ammoniacal nitrogen, nitrate, dissolved iron, sulfides exceeded limits established by Brazilian water quality regulations (CONAMA 357/2005). alteration reveals primary threat ecosystems is sewage collection treatment issues, reflecting absence basic sanitation. Redundancy Analysis (RDA) indicated influence specific types degraded streams, while preserved showed correlation between with riparian forest conditions anthropogenic influence. Cluster emphasized importance integrating environmental, hydromorphological, metrics for comprehensive assessment ecosystem health.

Abstract Despite their socio-economic and ecological functions, urban rivers are among the most endangered threatened ecosystems, especially in developing countries, where impact of population growth, urbanization, etc., on river ecosystem is more pronounced. Reliable affordable bioassessment tools fundamental for managing restoring ecosystems. This study collected macroinvertebrates from a typical Pearl River Delta region dry season (December 2021 to January 2022) wet (May June 2022). Family sensitivity values (FSVs) were revised based local biotic abiotic data, then used adapt Biological Monitoring Working Party (BMWP) Average Score per Taxon (ASPT) indices. The employed Shapiro-Wilk normality test linear regression model analyze fitting relationship between bio-indices Water Quality Index (WQI), compared differences using origin FSVs FSVs. results indicated that decreased. Furthermore, due macroinvertebrate taxa composition water quality conditions seasons, differed two lower FSV specific family recommended, reflecting limit pollution tolerance. adapted BMWP ASPT indices provide accurate assessment reliable indicators rivers. Thus, indicator suitable tool subtropical this region, allowing identification priority areas management recovery plan.
