Understanding how assemblages are structured in space and the factors promoting their distributions is one of main goals Ecology, however, studies regarding distribution organisms at larger scales remain biased towards terrestrial groups. We attempt to understand if structure stream fish metacommunities across a Neotropical ecoregion (Upper Paraná—drainage area 820,000 km2) affected by environmental variables, describing natural gradient, anthropogenic impacts spatial predictors. For this,...
Abstract Understanding variability in the composition of aquatic assemblages requires a multiscale perspective, since processes operating at different spatial scales (from regional to local) drive community assembly. Here, relative importance environmental variables on fish species streams Brazilian savanna ( Cerrado ) is assessed and quantified local landscape scales. The both structuring was supported. Local explained substantially higher amount variance than variables. However, shared...
ABSTRACT The economic and scientific interest in Hancornia speciosa (mangabeira) has been growing recent years, mainly due to the marketing of fruit extraction natural compounds with high pharmacological potential. In this study, a scientometric survey about mangabeira was carried out order promote direct future studies on species. As result, low productivity associated species found, only 131 articles published last 69 years. addition, study identified some trends bibliographic production...
O Cerrado (Savana brasileira) e o segundo maior bioma brasileiro, sendo considerado um hotspot de biodiversidade, pois apresenta elevado endemismo esta sob intensa ameaca. objetivo deste trabalho foi destacar as tendencias das publicacoes sobre Cerrado, detectar possiveis lacunas indicar direcoes futuras para trabalhos cientificos nesse bioma. Foi realizada uma busca artigos utilizando-se a base periodicos do Institute for Scientific Information (ISI), entre os anos 1991 2012. observado...
Abstract Aim: Chlorophyll-a may be directly influenced by local variables and/or indirectly land use and cover, once landscape modifications change limnological variables, which in turn affect the primary productivity of aquatic environments, e.g., streams. Therefore, objective this study was to determine relative importance environmental components assess direct indirect effects these on sestonic chlorophyll-a concentration 30 Cerrado streams (Santa Teresa River basin). Results All...
Chlorophyll is a green pigment common to all photosynthetic cells of autotrophic organisms in aquatic or terrestrial environments.Techniques used quantify this include fluorescence, UV spectrophotometer, chromatography, HPLC, and remote sensing.Determination the chlorophyll -a (Chl-a), has been widely many areas science.The present study investigated state global scientific literature on Chl-a, determining countries, approaches, environments where Chl-a studied geographic scale used.To...
O uso e ocupação do solo de forma desordenada leva a degradação ambiental perda recursos. Este cenário tem sido observado para o Cerrado. A vegetação bioma intensamente convertida ao longo tempo diversos fins. presente trabalho teve como objetivo avaliar cobertura através uma série histórica 28 anos na bacia rio Santa Teresa, estado Goiás. Foram obtidas imagens dos satélites Landsat 5 8 os 1985, 1997 2013. As foram processadas usando programa ENVI 4.7 ArcGIS 10.0. De 1985 até 2013 houve...

Abstract Aim The riparian zones of the Cerrado biome have decreased significantly due to human expansion, altering ecological dynamics ecosystems, and zooplankton can respond these changes. Therefore, we seek evaluate impact environmental changes on communities in streams, considering trophic state integrity zones. research seeks determine which predictors play most significant role structuring communities. main hypothesis is that local factors a direct influence nearby limnological...
Abstract: Aim We described the diet of generalist stream fish Knodus chapadae and we tested if environmental conditions are associated with population’s individual specialization. Methods analyzed stomach contents 287 individuals from 29 streams Brazilian savanna (Cerrado). Results The instream physical habitat structure, physiochemical conditions, adjacent land use explained partially variation in populations, but not Thus, changes observed at populational level were driven by average...
The organization of species metacommunities can be controlled by local factors, such as habitat quality, landscape land use, and spatial stream network distances. Species within a metacommunity have different traits that may used to understand the determinants community structure. This study aimed how changes in environmental factors affected fish assemblages delineated based on their dispersal-related traits, preferential use (i.e., benthic, nektobenthic, nektonic, marginal, surface),...
O uso de plantas medicinais para fins terapêuticos é uma prática utilizada desde os primórdios da humanidade até dias atuais. Cerrado considerado um hotspot biodiversidade. De toda a diversidade florística existente no bioma há aproximadamente 220 espécies que são utilizadas diretamente pelo homem. objetivo do trabalho foi avaliar percepção moradores Cidade Goiás sobre o e impactos ambientais vegetação Cerrado. Foram feitas 40 entrevistas com Município através abordagem direta utilização...
Brazilian watersheds have a high species and natural resources biodiversity. To know the features of scientific production on these regions is important to adjust study focus determine publication biases. This aims at characterizing literature about scientometric grounds. For this purpose, we performed search articles in ISI Web Science database Institute for Scientific Information (ISI). The returned 2,945 articles: 1,613 Amazon basin, 584 La Plata 262 São Francisco 190 Tocantins 117...
Fruto da cooperação entre o Brasil e a China, CBERS (Satélite Sino-Brasileiro de Recursos Terrestres) é um programa ao desenvolvimento satélites sensoriamento remoto qual tem contribuído entendimento diversos fenômenos gerenciamento territorial. Embora haja produção conhecimento partir dados do CBERS, esta ainda não foi caracterizada na literatura científica global. Desse modo, objetivo trabalho avaliar, por meio uma análise cienciométrica, as tendências lacunas dos estudos relacionados uso...
The development of multimetric indices to measure the biotic integrity aquatic habitats is based on metrics derived from biological assemblages. Considering fish assemblages, lack consistency in metrics’ responses outside places where they were developed limits indices’ transferability and applicability other locations, requiring local standardization. factors behind low these bioindicators are still poorly understood. We investigated how environmental dissimilarity spatial distance...
