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 Sensitive and cost‐effective indicators of aquatic ecosystem condition in A mazon streams are necessary to assess the effects anthropogenic disturbances on those systems a viable ecologically meaningful manner. We conducted present study municipality P aragominas, state ará, northern B razil, where we sampled adult dragonflies 50 100‐m‐long wadeable stream sites 2011. collected 1769 specimens represented by 11 families, 41 genera 97 species. The suborder Z ygoptera contributed 961...
Oil palm plantations have expanded around the world, increasing concern about its pressure on deforestation rates and homogenization of landscape. In this context, present study aimed to evaluate impact oil physical characteristics streams in Amazonia their effects Heteroptera, Odonata Fish assemblages. A total 23 were sampled, eight within fragments primary forest, while 15 plantations. Data collected channel morphology, substrate, hydraulics, instream cover for aquatic organisms, riparian...
A retirada ou a substituição da vegetação ripária provoca uma alteração no ambiente físico, fluxo sazonal e na qualidade química água. Essas modificações podem causar diminuição riqueza pela extinção local de espécies. O objetivo deste trabalho foi avaliar o efeito do distúrbio integridade ambiental sobre composição espécies Odonata adultos em córregos com diferentes níveis conservação, Bacia Rio Suiá-Missu, Mato Grosso, Brasil. As nos sistemas aquáticos afetaram comunidade Odonata,...
Os planos de transição energética muitos países em desenvolvimento dependem da expansão energia hidrelétrica, como fontes renováveis. Contudo os impactos cumulativos múltiplas barragens ainda precisam ser integrados às avaliações impacto ambiental. Estabelecer melhores conexões entre serviços ecossistêmicos e dentro cada bacia hidrográfica nos permite identificar benefícios ecológicos perdidos ou otimizar compensações inevitáveis. Aqui, destacamos principais desafios para a ecorregião do...
The effects of the implantation oil palm plantations on a series environmental variables and diversity distribution mayfly nymphs was investigated through survey 23 streams located in areas plantation natural forest eastern Amazon basin. Composition richness genera were compared among order to verify which respond habitat disturbance gradient determine thresholds for each variable. number higher streams, although genus composition similar between treatments. Only 9 114 physical measured...
Community diversity is expected to reflect variations in local conditions but, recently, ecologists have started realize that also under pressure from global processes. As a result, the traditional view of community structure based on interspecific interactions was replaced by idea result multiple processes acting different spatial scales. This study aimed at quantifying relative importance spatial, environmental and spatially structured Ephemeroptera Cerrado streams Brazil. Thirty-four...
Preserved riparian vegetation usually has greater environmental complexity than the modified by human actions. These systems may have a availability and diversity of food resources for species. Our objective was to evaluate effect changes on structure forest species richness, beta composition butterfly in Cerrado Mato Grosso. We tested hypotheses that: (i) higher richness (ii) would be recorded more preserved environments; (iii) homogeneous disturbed habitats. For hypothesis testing, eight...
Abstract Environmental changes are increasingly frequent, resulting in adverse impacts on biodiversity. These effects more harmful when superimposed areas of high biodiversity such as the Amazon region, which gaps knowledge number existing species and how they distributed. This article reviews known geographical distributions Ephemeroptera Brazilian based current uneven sampling effort to identify hotspots poorly protected, where work is required address conservation needs this group. A...
We analyzed the effects of environmental factors on abundance, species richness, and functional group richness Leptophlebiidae in 16 sampling points along four Cerrado streams. Across three periods 2005, we collected 5,492 larvae from 14 stream bed substrate. These belong to feeding groups: scrapers, filtering collectors shredders. The abundance were not affected by water quality, but habitat quality related presence riparian vegetation had positive Our results add important information...
ABSTRACT The present study evaluated the potential for reduction of sampling effort in studies ephemeropteran nymphs Brazilian Amazon streams, Pará State, Brazil, without loss ecological information (species composition, abundance, and richness), congruence different levels taxonomic resolution (morphospecies, genus, family functional group). Test groups 15, 10 five subsamples were selected from 20 collected per stream (40 streams sampled), compared terms their species richness abundance...
O objetivo deste trabalho foi responder se existe padrão na distribuição espacial das ninfas de Ephemeroptera em diferentes córregos e rios da bacia do Rio Suiá-Miçú, MT, como os estudados estão classificados acordo com a composição espécies. Na coleta foram amostrados 12 rios, três períodos ano. Foram coletados 1356 indivíduos, distribuídos sete famílias, 31 gêneros 42 espécies e/ou morfoespécies. Os locais mais abundantes ambientes semi-lênticos, pouco sombreamento no leito, sugerindo que...
Analisamos a estrutura dos grupos funcionais alimentares de Ephemeroptera em cinco tipos substratos (folhiço corredeira, folhiço remanso, madeira, pedras e raízes) trechos primeira quinta ordens da bacia do rio Pindaíba, estado Mato Grosso, Brasil. Verificamos, ainda, preferência táxons por específicos através especificidade frequência organismos, se abordagem funcional reflete as variações dentro comunidade. Nossos resultados agregam informações respeito classificação efemerópteros mostram...
Com o objetivo de apresentar um levantamento da fauna Ephemeroptera no Estado do Mato Grosso, investigamos as ninfas Ephemeroptera, principalmente duas bacias hidrográficas leste estado. Sessenta e sete espécies/morfoespécies em 41 gêneros oito famílias foram encontradas. Quatro espécies (Cloeodes redactus Waltz & McCafferty, 1987 Waltzoyphius roberti Thomas Peru, 2002 [Baetidae], Tricorytopsis chiriguano Molineri, 2001 [Leptohyphidae] Microphlebia surinamensis Savage Peters, 1983...
This study reviewed the data on Brazilian Ephemeroptera, based studies published before July, 2013, estimated number of species still to be described, and identified which regions country have been subject least research. More than half are known from description only one developmental stage, with imagoes being described more frequently nymphs. The Northeast is region weakest database. Body size affected rates, a strong tendency for larger first. unknown was accentuated by fact that so few...
We evaluated the concordance between assemblages of Ephemeroptera and Trichoptera to verify if they respond similarly environmental gradients in basin Suiá-Missu river Mato Grosso, central Brazil. tested predictions that: (i) distributional pattern mayfly caddisfly larvae is concordant along spatial (ii) variation basin, (iii) taxa are themselves seasons with disregarding year. found a species composition fall-water rainy period, when analyzed separately by each season. The variables two...
