Abstract Understanding the effects of mining activities on Amazonian streams and their impact aquatic communities is paramount importance in current context resource overexploitation society. In this study, we assessed significance environment interspecific interactions organization patterns semiaquatic insect species a mineral extraction region eastern Amazon. We utilized morpho functional characteristics 22 from suborder Gerromorpha (Heteropteran), considering both abundance sexual dimorphism these species. Additionally, quantified density riparian vegetation surrounding each stream to categorize sampling points evaluate whether there are differences distribution among categories. sampled 16 sites, categorized into two treatments based percentage forested deforested areas located Capim River Basin. did not find action environmental filters total assembly; however, found significant morphological divergence for all traits analyzed. On other hand, separation with different portions showed that between them regarding patterns. Forested within 500m radius have distributed over larger area, indicating greater availability or can use resources more efficiently. Our results demonstrate studied communities, as well mitigating impacts caused by activities.

Deforestation is a major threat globally, but especially in tropical regions because they are biodiversity strongholds and carbon storehouses. Some studies have reported changes species richness composition lotic ecosystems with increased forest-loss their catchment, presumably resulting from the replacement of sensitive taxa by more resistant or tolerant taxa. Also, respond to deforestation non-linear manner fish macroinvertebrates different sensitivities landscape pressures. Therefore, it useful determine effects on widespread threshold aquatic ecosystems. We used Threshold Indicator Taxa Analysis (TITAN) assess land use history impacts 92 eastern Amazonian stream sites. determined TITAN peak-change thresholds for at 1% 6% total-catchment local-riparian spatial extents, respectively, 2% 40% land-use intensity change respectively. For macroinvertebrates, were 11% forest loss 3% both extents. Because these thresholds, inherent ecoregional variability key literature, we three recommendations. 1) Logging should be prohibited riparian reserves that least 100-m wide each side headwater streams network catchments across all biomes as many types possible. 2) An ecologically statistically rigorous monitoring program standard methods implemented regulate uses better. 3) Conservation planning areas consider biota well terrestrial biota.

Wing polymorphism is common in insects and generally associated with environmental variation, thus, this characteristic can express different phenotypes under cues. Thereby, organisms a greater dispersal capacity are more related to heterogeneous environments, while wingless have investment reproduction even habitats suboptimal conditions. This study evaluated the efficacy of wing dimorphism semiaquatic bugs as tool assess altered streams oil palm plantations. We sampled 27 Eastern Amazon, classified preserved areas plantation areas. The total matrix sites x species was broken down two derived matrices, deconstructed winged individuals. concordance between matrices by Procrustes analysis. For each dataset, we used t-test evaluate richness loss model selection effect variables on richness. There number phenotype Only had structure congruent overall community matrix.

Abstract Metacommunity theory seeks to explain how local and regional processes contribute the organisation of biological communities. Recent conceptual frameworks this indicate that dynamics populations communities are jointly established by dispersal, species responses environmental conditions biotic interactions dependent on density. Here, we use hierarchical joint distribution modelling verify effects factors (at multiple spatial scales), drainage network configuration, autocorrelation interspecific structure fish assemblages in terra‐firme streams Eastern Brazilian Amazon. Thirty were sampled two field surveys, 89 collected total. Our results confirm limited scales) configuration these assemblages. Furthermore, our suggest less relevant for structuring metacommunities small Amazonian headwater streams. Abiotic like networks heterogeneity better predictors distributions than co‐occurrence patterns with potential competitors or predators.
