Three new species of Melanophryniscus are described from the Serra do Mar mountain range of the state of Santa Catarina, southern Brazil. All species are found at intermediate to high altitudes and share phytotelm-breeding as their reproductive strategy. The new species are distinguished from other phytotelm-breeding Melanophryniscus based on different combinations of the following traits: snout-vent length, presence of white and/or yellow spots on forearms, mouth, belly and cloaca, pattern and arrangement of warts, and presence and number of corneous spines. The discovery of these species in a rather restricted geographical area suggests that the diversity of phytotelm-breeding species of Melanophryniscus might be severely underestimated. The conservation status of these species is of particular concern, given that one of them is at risk of extinction not only due to its restricted habitat, but also because of anthropogenic disturbances. © 2015 Bornschein et al.

The colubrid snake Chironius fuscus (Colubridae) is a widely distributed species in South America, exhibiting a disjunct distribution associated to rainforests of Amazonia and Eastern Brazil (from Pernambuco to Paraná States). In this study, we present new distributional data from Paraná state and extend the known range to the state of Santa Catarina. We also present meristic and morphometric data of the southernmost populations of the species. © 2012 Check List and Authors.

The effect of land cost in the forest profitability: a case study for Santa Catarina. This research aimed to ascertain the impact of land cost land on profitability of Pinus spp. timber production. The forestry sector has as key feature to generate financial returns in the long term, often making the investment activity in a large barrier to new business. The price of land is a variable that depends on the return of forest activity, making it necessary to know the effect that the cost of this resource will have on profitability. In order to estimate return on forest activity, it uses economic criteria, like Net Present Value (NPV) and Internal Rate of Return (IRR). The results proved to be more attractive the nonacquisition of land, with NPV of US$ 5.5804,00 and IRR of 18% per year. Considering the investment in land (purchase or lease), the economic results have suffered reduction with NPV of US$ 3.711,00 and IRR of 11% per year. The lease of land presented a NPV of US$ 3.531,00 and IRR of 13% per year. But, before using such criteria as the only decision making, other factors must be evaluated as to obtain the income of the legal reserve, the better level of use of land and a proper forest management, aiming to increase revenue with the acquisition of new products and increased production of forests.

Soil erosion data in El Salvador Republic are scarce and there is no rainfall erosivity map for this region. Considering that rainfall erosivity is an important guide for planning soil erosion control practices, a spatial assessment of indices for characterizing the erosive force of rainfall in El Salvador Republic was carried out. Using pluviometric records from 25 weather stations, we applied two methods: erosivity index equation and the Fournier index. In all study area, the rainiest period is from May to November. Annual values of erosivity index ranged from 7,196 to 17,856 MJ mm ha-1 h-1 year-1 and the Fournier index ranged from 52.9 to 110.0/mm. The erosivity map showed that the study area can be broadly divided into three major erosion risk zones, and the Fournier index map was divided into four zones. Both methods revealed that the erosive force is severe in all study area and presented significant spatial correlation with each other. The erosive force in the country is concentrated mainly from May to November. © 2011, Mary Ann Liebert, Inc. 2011.

The Brazilian Atlantic Rainforest has high diversity levels of amphibians and reptiles, but there is a lack of richness survey at several areas, while a high level of deforestation is already known. The biome is highly endangered in northeastern Brazil, and few protected areas have been the main mechanism for providing the habitat conservation. We studied the Refúgio da Vida Silvestre Mata do Junco, a recently established conservation unit in this biome, at the Capela municipality, in the state of Sergipe. Field surveys and literature review were conducted between 2007-2009, revealing 33 species of anuran amphibians and 26 of reptiles (one turtle, ten lizards and 15 snakes). The presence of rare and endemic species suggests an important role of this area as a source remnant of the northeastern Atlantic Forest herpetological community. © 2011 Check List and Authors.
