Pesticide residues in river sediments from the Pantanal Wetland, Brazil.
Sediment samples from 25 sites in 17 rivers of the Pantanal (Brazil) were analyzed with the objective of evaluating pesticide contamination in sediments. Samples were extracted with an acetone, ethylacetate, and water mixture 2:2:1 (v/v/v). The extract was purified by flash chromatography with aluminum oxide and florisil. A multiresidue gas chromatography-mass spectrometry method was applied to...
متن کاملBirds' nesting parameters in four forest types in the Pantanal wetland.
We tested the heterogeneity/productivity hypothesis with respect to the abundance and richness of birds and the vegetation density hypothesis with respect to birds' nest predation rates, and determined the relative importance of forested vegetation formations for the conservation of birds in the Pantanal. We estimated the apparent nesting success, and the abundance and richness of nesting birds...
متن کاملPlant diversity of the Pantanal wetland.
This is a review of current studies in diversity of the flora and main vegetation types in the Brazilian Pantanal. The flora of this wetland, nearly 2,000 species, constitutes a pool of elements of wide distribution and from more or less adjacent phytogeographic provinces, such as Cerrado, dry seasonal forests, Chaco, Amazonia and Atlantic Forest. The most numerous group includes wide-distribut...
متن کاملEffects of Severe Floods and Droughts on Wildlife of the Pantanal Wetland (Brazil)—A Review
Flooding throughout the Pantanal is seasonal. The complex vegetative cover and high seasonal productivity support a diverse and abundant fauna. A gradient in flood level supports a range of major habitats in a complex mosaic with annual seasonality. The rivers and streams are lined with gallery forests, and other arboreal habitats exist in the more elevated areas. The remainder is either grassl...
متن کاملDistribution patterns of Convolvulaceae in Iran: priorities for conservation
Assessing priorities is the most important action in conservation programs. Rudimentary, mapping of diversity, and distribution patterns have been used to set priorities on diverse scales. The distribution patterns of plant taxa, largely reflect an actual ecological niche. Convolvulaceae s.str exhibits cosmopolitan dispersal of diverse life forms and includes 50–60 genera comprising 1600–1700 s...
