Citizen science as a monitoring tool in aquatic ecology: trends, gaps, and futu...

Aquatic ecosystems are essential for biodiversity and ecosystem services, but anthropogenic pressures threaten them. In this context, citizen science has emerged as an innovative strategy for biodiversity conservation and environmental monitoring. We conducted a scientometric analysis to identify patterns and gaps in the scientific literature on citizen science in aquatic ecology. We analyzed 185 articles publi...

Thresholds of freshwater biodiversity in response to riparian vegetation loss i...

No. of bitstreams: 0 Previous issue date: 2020-07-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and in maintaining aquati...

Effect of the abiotic factors on brachymetra albinervis albinervis (Heteroptera...

We analyzed the influence of abiotic factors, longitudinal and temporal distribution on the abundance of Brachymetra albinervis albinervis Amyot & Serville, 1843. Three sites of Cerrado stream were assessed: headwater, intermediary and river mouth, monthly for a year (June 2011 to May 2012). At each site, the following abiotic variables were monthly measured in a linear 100 meters transect: dissolved oxygen, wa...

A social and ecological assessment of tropical land uses at multiple scales: Th...

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers...

Macro-scale (biomes) differences in neotropical stream processes and community ...

The definition of conservation strategies and ecological assessment schemes requires understanding ecosystem patterns over multiple spatial scales. This study aimed to determine if macro-scale structural and functional (processes) patterns associated with stream ecosystems differed among three neotropical biomes (Cerrado, Amazon, Atlantic Forest). We compared the aquatic communities (benthic invertebrates and h...

Effect of adult abundance on nymphs of Gerromorpha (Heteroptera) in Cerrado str...

How species interact with each other and how the environment affects species are subjects that ecologists still need to better understand. Our objectives were to evaluate the effect of (i) the abundance of Gerromorpha adults, (ii) habitat integrity, and (iii) morphological conditions (width, depth and slope) of streams on the abundance of nymphs of semiaquatic Heteroptera (Gerromorpha). Sampling was carried in ...

The response of neotropical dragonflies (Insecta: Odonata) to local and regiona...

Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the Amazonian region. Adult Odonata were sampled in 98 streams in the Eastern Amazon, Pará, Brazil. Six variables were used to measure local environmental factors: habita...

Do landfills affect the environmental quality of nearby streams?

When inappropriately disposed, solid waste may contaminate the soil, water and air, leading to severe negative impacts on biodiversity. The Brazilian National Policy for Solid Waste (PNRS) requires municipalities to ensure the environmental quality of landfills. Accordingly, our objective was to evaluate the community of aquatic insects in a stream with stretches downstream and upstream of a sanitary landfill. ...
