“…These riparian strips may have contributed to making the impacts of intense land uses on communities more subtle, and this could only be detected with a dissimilarity coefficient based on changes in species abundance. Previous studies have shown that subtle environmental changes do not alter species occurrences strongly but affect more sensitive and rare specialists (Callisto et al, 2021; Dias et al, 2010; Siqueira et al, 2015). The lack of relationship between variation in species composition estimated with Jaccard and Bray‐Curtis and environmental predictors indicate that the environmental change in our study area has not led to complete abiotic and biotic homogenization (Leão et al, 2020).…”

Environmental and spatial heterogeneity affects the distribution of aquatic insects, determining or influencing the variation in local species composition. Dragonflies and damselflies (Odonata) have different strategies for oviposition site selection that depend on environmental conditions. However, Land Use and Land Cover (LULC) can reduce the availability of suitable sites for Odonata oviposition through environmental homogenization. We investigated the relationship between environmental and spatial heterogeneity and variation in species composition of Odonata with different oviposition strategies (endophytic, epiphytic and exophytic) in Amazonian streams in a gradient of LULC. We used the Jaccard and Bray‐Curtis coefficients and the Manhattan distance to estimate a continuum of variation in species composition. Variation in the composition of endophytic and epiphytic species was explained by spatial heterogeneity. Using abundance data and the Manhattan distance, we found a relationship between variation in species composition and environmental heterogeneity. Endophytic species composition was related to perch heterogeneity, while exophytic species composition was related to perch and canopy cover heterogeneity. Exophytic and endophytic species could be used in biomonitoring as they respond to specific environmental predictors and because exophytic species do not have spatial patterns across the landscape. Different dissimilarity coefficients provide complementary information about the responses of multispecies communities to land use, as some will represent strong effects (presence‐absence indexes) while others will represent more subtle effects (abundance‐based indexes). Land use can increase the environmental heterogeneity of some predictors (perches and canopy cover). Physical changes in streams such as hydromorphological alterations can modify specific habitats, affecting oviposition strategies and supporting tolerant species.

“…The presence of algae and macrophytes may be related to high habitat complexity and shelter and food resources increasing the density and diversity of benthic macroinvertebrates (Rezende et al, 2019b), thus also explaining the high macroinvertebrate density and α diversity in silviculture areas. In this sense, two families of the order Ephemeroptera (Baetidae and Leptohyphidae) that occur with high densities in silviculture streams are mostly of the collector feeding group, which benefit from litter decomposition (Callisto et al, 2021;Firmiano et al, 2021). On the other hand, the family Chironomidade was the most abundant in streams without arboreal riparian vegetation.…”

“…It is noteworthy that most of these studies focused on forest streams and only a few studied the macroinvertebrate fauna of subtropical grasslands (Baptista et al, 2014;Hepp & Melo, 2013;Hepp et al, 2021;Loureiro et al, 2018Loureiro et al, , 2021Tonello et al, 2021), few of which were in highland grasslands (Galeti et al, 2020;, Montilla et al, 2022Principe et al, 2015). Similarly, subtropical highland grasslands have been understudied compared to tropical highland grasslands (Callisto et al, 2016(Callisto et al, , 2021Castro et al, 2019). In general, areas with highly connected environments tend to have similar physical-chemical habitat characteristics, resulting in the same specific macroinvertebrate composition (Rezende et al, 2014b;Hepp et al, 2021).…”

Knowledge of the frequency and occurrence of macroinvertebrates throughout landscapes may clarify the effects of anthropic impacts on aquatic systems and help guide conservation actions for watersheds. We evaluated macroinvertebrate α and β diversity in streams in four different subtropical phytophysiognomies: highland grasslands with arboreal riparian vegetation, highland grasslands without arboreal riparian vegetation, mixed ombrophilous forest and silviculture. We also evaluated how environmental factors influence α diversity. We sampled macroinvertebrate communities (by Surber sampler), litter input (by nets) and physicochemical variables of the water (by multiparameter and chemical analysis) at 10 sites in riparian zones of a highland system. A total of 2124 individuals were sampled representing 41 taxa, with high α and β diversity in mixed ombrophilous forest. The results indicate that environmental heterogeneity increases food resource availability, as well as macroinvertebrate diversity. Furthermore, the β diversity was found to increase with distance among the unconnected streams. Areas of silviculture had the highest density values among the sampled areas due high organic material stock in the soil. Therefore, higher leaf litter input may decrease the toxicity effect of secondary compounds released by leaf plant decomposition compared to environments with low systemic leaf litter input, such as highland grasslands. The presence of arboreal riparian vegetation drives canopy openness, water temperature, dissolved oxygen, and orthophosphate in streams, which control the frequency and occurrence of benthic macroinvertebrates. Homogeneous systems, as naturally observed in highland grasslands, plus high canopy openness decrease macroinvertebrate richness and density. The naturally low richness of highland grasslands, although with endemic species, may be an important guideline for legislation on anthropic impacts, management, and conservation of streams in this specific subtropical zone.

“…Headwater streams are ubiquitous in river landscapes and are important sources of biota for downstream reaches, and critical sites for maintaining the ecological integrity and health of whole river networks ( Clarke et al, 2008 ; Finn et al, 2011 ; Callisto et al, 2021 ). Understanding their biological diversity and community assembly is fundamental to monitoring and management ( Clarke et al, 2008 ; Finn et al, 2011 ).…”

Headwater streams are highly heterogenous and characterized by a sequence of riffles and pools, which are identified as distinct habitats. That higher species richness and density in riffles than in pools is considered a general pattern for macroinvertebrates. As temperate winters can last long up to half a year, however, macroinvertebrate communities of riffles and pools may assemble differently under ices or snows. Particularly, defoliation concentrating in autumn can largely change habitats in both riffles and pools by litter patching. According to the absence or presence of litter patches, there exist four types of subhabitats, i.e., riffle stones, riffle litters, and pool sediments, pool litters, which are selectively colonized by macroinvertebrates. To study the spatial pattern and temporal dynamics of colonization, macroinvertebrates were surveyed in a warmer temperate forest headwater stream in Northeast China during four periods: autumn, pre-freezing, freezing, and thawing periods. Our study focused on functional trait composition, functional diversity and functional redundancy of macroinvertebrate communities. The colonization of macroinvertebrates was found to be significantly different in these subhabitats. Riffle stones supported higher taxonomic and functional diversities than pool sediments; litter patches supported higher total macroinvertebrate abundance and higher functional redundancy than riffle stones or pool sediments. The functional trait composition changed significantly with seasonal freeze-thaw in both riffle stones and pool sediments, but not in litter patches. Macroinvertebrate community in litter patches showed seasonal stability in taxonomic and functional diversities and functional redundancy. Thus, this study strongly highlights that litter patches play an important role structuring macroinvertebrate community over winter, supporting high abundance and maintaining functional stability.
