Abstract Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and maintaining aquatic biodiversity. Thus, identifying ecological thresholds useful for defining regulatory limits guiding management zones towards conservation biota. Using nationwide data fish invertebrates occurring small Brazilian streams, we estimated native loss which there are abrupt changes occurrence abundance bioindicators tested...
Abstract Context Global change, including land-use change and habitat degradation, has led to a decline in biodiversity, more so freshwater than terrestrial ecosystems. However, the research on freshwaters lags behind marine studies, highlighting need for innovative approaches comprehend biodiversity. Objectives We investigated patterns relationships between biotic uniqueness abiotic environmental drainage basins worldwide. Methods compiled high-quality data aquatic insects (mayflies,...
It is well recognized that assemblage structure of stream macroinvertebrates changes with alterations in catchment or local land use. Our objective was to understand how the trophic ecology benthic macroinvertebrate assemblages responds use tropical streams. We used isotope methodology assess energy flow and relations among were affected environments by different uses (natural cover, pasture, sugar cane plantation). Macroinvertebrates sampled categorized into functional feeding groups,...
Headwater streams are facing increasing disturbances from human pressures worldwide, thus better knowledge about bioindicators, particularly aquatic insect responses to various and stressors, urgently needed. Multiple trait-based approaches consider species attributes filtered by the environment, allowing them persist in ecosystems under environmental pressures. Because this approach has been minimally explored Odonata larvae, we aimed understand how anthropogenic stressors structure larval...
Summary Stream invertebrate assemblages are structured by environmental factors acting at multiple spatial scales. Identifying the scale that most influences species–environment relationships is a major goal of community ecology. We evaluated importance catchment and site scales associated variables in shaping Ephemeroptera, Plecoptera Trichoptera (EPT) Neotropical savanna headwater streams. Sampling sites were with 20 catchment‐scale depicted land cover use as well natural geophysical such...
Abstract Mountains harbor rich biodiversity and high levels of endemism, particularly due to changes in environmental conditions over short spatial distances, which affects species distribution composition. Studies on mountain ecosystems are increasingly needed, as mountains highly threatened despite providing ecosystem services, such water supply for half the human population. We aimed understand patterns drivers alpha beta diversities aquatic invertebrates headwater streams along an...
The effects of anthropogenic disturbance on multiple facets biodiversity are poorly understood. In this study, we worked with the hypothesis that disturbances affect relationship between environmental heterogeneity (EH) and biodiversity. We used a model selection approach to test three predictions. P1: greater level disturbance, weaker will be EH both taxonomic functional alpha diversities. P2: sign strength correlations metrics diversities depend disturbance. P3: Taxonomic beta not respond...
The aim of this study was to test if changes in land use alter the isotopic signature fish species, promoting trophic position and food resource partitioning between these consumers. Three different systems were investigated: pasture streams ( n = 3), sugar cane plantations 3) reference 3). Fish species Aspidoras fuscoguttatus , Astyanax altiparanae Characidium zebra Hisonotus piracanjuba Knodus moenkhausii selected, their nitrogen carbon compositions estimated assess level items consumed....
The drivers of dissimilarity in biological communities among habitats and the mechanisms that modulate distribution functional diversity streams are still important gaps ecological knowledge. This study was designed to assess how taxonomic composition Cerrado stream insect assemblages distributed multiple spatial scales (i.e., habitat, sites hydrological units). To do so we used a hierarchical series four components: transect (α), transects (β1), (β2), units (β3). Our aim identify at which...
Invertebrate drift results from several factors, including accidental dislodgement the substratum, interaction with other invertebrates and predators, changes in water quality, discharge current velocity. We evaluated degree to which flow fluctuations dam releases altered daily seasonal invertebrate patterns a tropical river. collected macroinvertebrates during fixed rates (323 m3.s−1 wet season 111 dry season) when peak flows fluctuated (378–481 109–173 2010.
