Distribuição, tamanho populacional, hábitat e conservação do bicudinho-do-brejo Stymphalornis acutirostris Bornschein, Reinert e Teixeira, 1995 (Thamnophilidae)

The Marsh Antwren (Stymphalornis acutirostris) is restricted to the lowlands between Antonina Bay, in the coastal plain of the state of Paraná, and Itapocu river, in the northern coastal plain of the state of Santa Catarina (from 0 to c. 5 m a.s.l.). It doesn't occur continuously in this region, being found in eight populations that span over an total area of about 6,060 ha (= area of occupancy; 4,856.67 in Paraná and c. 1,200 in Santa Catarina). Nine habitat types used by the Marsh Antwren were defined, based on vegetation physiognomy, localization, dominancy of botanical species, dominant life-form and history of the region. Five of these are herbaceous (marshes), while four have an upper arboreal stratum and an herbaceous lower stratum with marsh plants. According to the classification criteria of the Brazilian vegetation proposed by the Radambrasil Project, they were classified as Pioneering Formation of Fluvial Influence, Pioneering Formation of Fluvial-marine Influence, and/or Pioneering Formation of Lacustrine Influence. They occur as patches or narrow strips ranging from 0.001 to 203.0 ha in the state of Paraná. They are found mainly in the interior of bays, in the lower courses of rivers that drain into bays, in alluvial plains, and between sand dunes in the coastal plain. Characteristic herbaceous species are cattail (Typha domingensis), bulrush (Scirpus californicus), Crinum salsum, Panicum sp. cf. P. mertensii, saw grass (Cladium mariscus) and Fuirena spp. Hibiscus pernambucensis is the characteristic bush species, and Calophyllum brasiliense, Tabebuia cassinoides, Annona glabra and Laguncularia racemosa are the characteristic arboreal species. The Marsh Antwren lives in herbaceous vegetation, but also uses bushes and branches of small tress. It has low flight capacity and a single flight of more than 25 m was never recorded. Territories of 0.25 ha were estimated in one kind of habitat (tidal marsh) (= 8 individuals per hectare) and of 3.2 ha in another one (saw grass marsh) (= 0.62 individual per hectare). The global population estimate is of about 17,700 mature individuals (13,700 in Paraná and 4,000 in Santa Catarina). The species is really under threat of extinction, mainly because of it's restricted geographical distribution and habitat loss by human activities and biological contamination caused by invasion of exotic grasses (Urochloa arrecta and Brachiaria mutica).

Restauração florestal visando à conservação de recursos hídricos por meio da combinação linear ponderada

This study evaluated using of Multicriteria Evaluation in a GIS, specifically by Weighted Linear Combination Method for generation of map of priority areas for forest restoration in the initial part of River Pardo Basin, SP, in order to water resources conservation. Aiming to define criteria and restrictions it was used Participatory Techniques, and the following factors had been selected: proximity of the hydrographic network, proximity of forest cover, slope and erodibility of soil. To calculate the weight to each factor it was used the decision-making process, known as Analytic Hierarchy Analysis, this method consists of a paired comparison of factors to determine the relative importance of each. According to Weighted Linear Combination, the very high priority areas have a more limited spatial distribution, with an apparent concentration around the water bodies, outlining a buffer to the river system. The proximity factor of the hydrographic network, and enables the connection forestry, contributed, along with the factor of proximity to forest cover, so there would be the definition of most of the areas with the highest priority in the basin, which concentrate the largest areas of forest and native riparian areas along the hydrographic.
