Summary: This study predicts the distribution of aquatic insects in a heterogeneous agricultural landscape for the first time using different landscape variables and random forest models. The predictions suggest that the occurrence of aquatic insects across terrestrial ecosystems is higher than previously thought.

Summary: This study used a risk model to identify species most likely to be affected by insecticides during the adult life stage, with mayflies being the least vulnerable and stoneflies and caddisflies being more susceptible. The findings suggest that species with specific life cycle characteristics should be targeted for future ecotoxicological tests.

Summary: Despite advances in recent years, there is still a lack of information on the habitat specificity of many aquatic insects, especially in diverse regions like the Amazon. This study evaluates the relationship between niche breadth and habitat specificity of aquatic insects in 219 streams. The results show that environmental changes can favor specialist insects and that some taxa occupy less frequently occupied habitats.

Summary: Mayflies, stoneflies, and caddisflies are aquatic insects commonly used as environmental quality indicators. This study focused on how these insects reacted to human-induced environmental gradients, particularly in a stream ecosystem impacted by mining, smelting activities, and high levels of pollutants. The results showed significant declines in stoneflies but higher abundances of caddisflies at affected sites, highlighting the complex responses of these insects to environmental stressors.

Summary: The study found significant differences in benthic macroinvertebrate fauna between caves of different lithologies, indicating potential regional influences. Cave lithology affects water chemical and physical characteristics, thus supporting different EPT assemblages.

Summary: This study evaluated the abundance and richness of generalist and specialist genera of EPT in response to mining activities in the Carajas National Forest, Brazil. It found that mining had a negative effect on the richness of specialists but a positive effect on their abundance. On the other hand, generalists negatively responded to mining in terms of richness and abundance.

Summary: This study examined the distribution patterns of Ephemeroptera, Plecoptera, and Trichoptera functional feeding groups (EPT FFGs) in streams in the Tsitsa River catchment in South Africa. The results showed that physicochemical variables, such as phosphate-phosphorus and total inorganic nitrogen, significantly influenced the distribution patterns of EPT FFGs. Collectors were the most abundant FFGs in the study area and their response was associated with phosphate-phosphorus.

Summary: We conducted a systematic review to analyze the characteristics of studies on the impacts of land use change on adult EPT communities. The results showed that most studies were conducted in Europe and North America, focusing on the group Trichoptera. Light traps were the most commonly used sampling method. The study also found significant differences in adult EPT communities between open areas and forests, suggesting negative impacts of forest conversion on these communities. This systematic review can provide important guidance for researchers in selecting appropriate collection methods and taxonomic groups for their studies.

Summary: The study investigated the impact of stream permanence on stonefly assemblage composition and spatial distribution in Mammoth Cave National Park. Different types of streams, including perennial spring runs, spring seeps, upland perennial streams, perennial riverine, and summer dry runs, were studied to understand the diversity of stonefly species and their adaptability to intermittent habitats. The results showed a significant difference in stonefly community structure between different types of streams, with species able to survive in intermittent habitats exhibiting life history adaptations such as desiccation tolerance as larvae or eggs.

Summary: This study identified rural indicator and sensitive traits of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa by examining their trait distribution pattern in relation to rural pollution. Traits such as large body size, swimming, and shredding were considered tolerant signature traits of semi-urban pollution, while small body size, operculate gills, spherical body shape, and preference for sediments were correlated with sensitive traits of semi-urban disturbance. Overall, the study provided critical insights into how semi-urban activities influence EPT traits in the Tsitsa River.

Summary: This study examined the responses of EPT taxa to major physicochemical and hydro-morphological factors, finding that their abundance and distribution were positively correlated with factors such as dissolved oxygen and pH. Significant biotypological differences were observed among different stream types, indicating a diverse range of EPT species in the Martil basin.
