Rivers suffer from multiple stressors acting simultaneously on their biota, but the consequences are poorly quantified at global scale. We evaluated biological condition of rivers globally, including largest proportion countries Global South published to date. gathered macroinvertebrate- and fish-based assessments 72,275 37,676 sites, respectively, 64 study regions across six continents 45 nations. Because were based differing methods, different systems consolidated into a 3-class system:...
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 Most metacommunity studies indicate that dispersal processes play a minor role compared with species sorting in explaining organisation, particular, stream systems. However, the of could vary environmental harshness, as result frequent resetting community succession by disturbances and selection generalist from regional pools. The importance may also be mitigated ability. In this study, we explored how shaped invertebrate fish metacommunities across streams three tropical headwater...
Abstract Several recent studies have demonstrated that a functional approach (i.e. analysis of traits indicating species ecological functions) can be successfully used for river biomonitoring. To date this has only been applied in temperate rivers, even though it could notably contribute toward the development an environmental assessment system developing countries other climatic zones. Using multivariate (Fuzzy Correspondence Analysis—FCA), we analysed invertebrate community characteristics...
The River Continuum Concept (RCC) explains the structural and functional characteristics of stream communities focusing on gradually changing physical components from headwaters to downstream habitats streams rivers. global value RCC is still uncertain, possibly because factors (e.g., altitude then temperature, order, channel width) can vary differently in longitudinal river axes across world. Moreover, predictions relation different have not been tested adequately biomes, especially biomes...
Summary The effect of drying events on aquatic biodiversity is still overlooked in wet Neotropical systems. Yet, the responses local communities and metacommunities these hotspots may differ from what reported other areas. We addressed regional fish macroinvertebrate headwaters Chipiriri River basin, piedmont Bolivia. According to current knowledge intermittent rivers ephemeral streams (IRES) ecology, we predicted that (INT) sites would harbour lower α‐diversity, but higher β‐diversity, than...
More than half of the world's rivers dry up periodically, but our understanding biological communities in riverbeds remains limited. Specifically, roles dispersal, environmental filtering and biotic interactions driving biodiversity are poorly understood. Here, we conduct a large-scale coordinated survey patterns drivers riverbeds. We focus on eight major taxa, including microorganisms, invertebrates plants: Algae, Archaea, Bacteria, Fungi, Protozoa, Arthropods, Nematodes Streptophyta. use...
Introduction: Spatial and temporal variation in the environment promotes biological diversity. However, combined effects of elevation, seasonality, habitat on butterfly diversity abundance are still underexplored rural tropical ecosystems. Butterflies, as bioindicators, offer an excellent opportunity to assess environmental impacts due their sensitivity changes habitat. Objective: This study aimed evaluate species richness across different habitats, elevations, seasons a mountain landscape...
Abstract More freshwater ecosystems are drying in response to global change thereby posing serious threat biota and functions. The production of desiccation‐resistant forms is an important adaptation that helps maintain biodiversity temporary freshwaters by buffering communities from drying, but its potential mitigate the negative effects could vary greatly across regions ecosystem types. We explored this context dependency quantifying contribution desiccation‐resistance invertebrate...
River networks are among Earth’s most threatened hot-spots of biodiversity and provide key ecosystem services (e.g., supply drinking water food, climate regulation) essential to sustaining human well-being. Climate change increased use causing more rivers streams dry, with devastating impacts on services. Currently, than a half the global river consist drying channels, these expanding dramatically. However, (DRNs) have received little attention from scientists policy makers, public is...
Productivity (trophic energy) is one of the most important factors promoting variation in species richness. A variety species-energy relationships have been reported, including monotonically positive, negative, or unimodal (i.e. hump-shaped). The exact form relationship seems to depend, among other things, on spatial scale involved. However, mechanisms behind these patterns are still largely unresolved, although many hypotheses suggested. Here we report a case local-scale positive...
El impacto de la estacionalidad los ríos sobre las comunidades macroinvertebrados fue estudiado en zona Altoandina Bolivia, durante época transición y seca del año 2008. En nueve arroyos intermitentes permanentes se colectaron muestras parámetros ambientales. A traves análisis multivariados, determinaron relaciones entre variables biológicas (según riqueza, abundancia, composición trófica rasgos biológicos) con La no tuvo efecto significativo riqueza ni densidad macroinvertebrados, tampoco...

Los ríos son grandes centros de biodiversidad, pero también los más amenazados por distintas actividades antropogénicas. El caso particular del río Quirpinchaca que atraviesa el centro la ciudad Sucre ha sufrido visiblemente serios daños y hasta ahora no existen estudios con base ecológica técnica permita evaluar restaurarlo. Por ello este trabajo pretende calidad (siete sitios) Cachimayu (tres usando a macroinvertebrados acuáticos como potenciales bioindicadores contaminación apoyados datos...

The compared with other in genus. Distributional records, diagnoses a key to distinguish genus are included. Se describe una nueva especie de élmido nov. e ilustra los adultos ambos sexos y la Esta es primera del género descripta para América Sur.
