Abstract The hypotheses that beta diversity should increase with decreasing latitude and spatial extent of a region have rarely been tested based on comparative analysis multiple datasets, no such study has focused stream insects. We first assessed how well variability in insect metacommunities is predicted by group, latitude, extent, altitudinal range, dataset properties across drainage basins throughout the world. Second, we relative roles environmental factors driving variation assemblage...
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,...
Summary 1. Lotic ecosystems can be studied on several spatial scales, and usually show high heterogeneity at all of them in terms biological environmental characteristics. Understanding predicting the taxonomic composition communities is challenging compounded by problem scale. Additive diversity partitioning a tool that occurs different scales. 2. We evaluated distribution benthic macroinvertebrates tropical headwater catchment (S.E. Brazil) during dry season compared alpha beta diversities...
An understanding of the interactions among local environmental factors (e.g., physical habitat and water quality) aquatic assemblages is essential to conserve biodiversity in tropical subtropical headwater streams. We evaluated relative importance multiple chemical variables that influence richness Ephemeroptera, Plecoptera, Trichoptera (EPT) wadeable Brazilian Cerrado (savanna) sampled macroinvertebrate quantified 79 randomly selected sites 2 basins southeastern Brazil. The by regression...
Abstract We evaluate the composition and structure of invertebrate assemblages during leaf breakdown five native tree species ( Myrcia guyanensis , Ocotea sp., Miconia chartacea Protium brasiliense heptaphyllum ) a mixture them in headwater stream, Southeastern Brazil. Coarse mesh litter bags were used over 120‐day period. P. showed slowest rate, while fastest. Total densities biomass values associated invertebrates different among types incubation periods. The highest total abundance found...
Areas with minimal anthropogenic influences are frequently used as reference sites and represent the best ecological state available in a region. Streams such conditions necessary for evaluating conservation status of aquatic ecosystems region to monitor them, taking natural environmental variability into consideration. Therefore, aim present study was analyse whether hydrological units reliable regional aggregating sites. To this end, were studied three different landscape same unit. The...
The number of disasters involving tailings storage facilities has increased in Brazil. Only the last six years, there have been this type structure. Despite vast socio-environmental impacts, little done to mitigate damage caused. negligence mining companies and lack efficient management approaches at river basin-level greatly hampered efforts for environmental recovery. In addition, although Brazil signed 2030 Agenda Sustainable Development, a slowdown Brazilian legislation, which can...
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...
Considering the increasing importance of analysing spatial structure in ecological studies, aims present study were to test whether fluvial distances and environmental factors are important drivers β-diversity stream fish assemblages, is different distinct hydrological periods. Specimens sampled at 33 sites eastern Amazon. Eight variables measured each site between pairs determined. Environmental main structuring assemblages both However, only during flood period. This can be related...
Phlebotomines (Diptera: Psychodidae) are vectors of several etiological agents human and animal diseases, including protozoans the gender Leishmania. Precarious socioeconomic conditions uncontrolled population growth directly influence transmission risk parasites urbanization vector species, previously restricted to wild environments. The Marajó Archipelago is considered a high incidence area leishmaniasis in Brazilian Amazon. However, it poorly studied. aim this study was assess adaptation...
Riverscape connectivity is a critically important component determining the ecological condition of lotic ecosystems. We evaluated changes in fish assemblages caused by loss mine tailings storage dams (TSDs), hypothesizing that headwater are restructured TSDs located downstream, even though upstream habitats not altered. used standard methods to collect 24 first third order sites, with half draining (dammed) and other free from this impact (undammed). To identify differences between...
Abstract Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment ecosystem health, well test ecological hypotheses. Despite their importance, a comprehensive, global database aquatic insect occurrences for mapping biodiversity in macroecological studies applied research is missing. We aim fill this gap present the Global EPTO Database , which includes worldwide geo‐referenced occurrence records four major...
