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.

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.

Human-induced habitat change is the main cause of species loss and can have severe effects on plant communities and the associated herbivore fauna. In this study, we investigated the effects of habitat conversion due to mining on communities of galling insects in areas of tropical rainforest in the Brazilian Amazon. We sampled galling insects in the Floresta Nacional de Saracá Taquera, Pará, Brazil, where forest plateaus are used by the Mineração Rio do Norte Group to extract bauxite. Our results show that human-induced habitat change via mining activities increased the local species richness of galling insects. We also found that after impact there was greater species richness of galling insects closer to the forest edge than in the forest interior. Changes in plant physiology and in the diversity of natural enemies in human-modified habitats, along with the endophagous life-form, might account for the high incidence of galling in human-disturbed habitats. This result highlights the importance of understanding how different insect groups respond to human activities, since such idiosyncrasies might have profound effects on the species’ patterns of ecological interactions and in the outcomes of those interactions. © 2014, Springer International Publishing Switzerland.

The objective of the present study was to characterise the floristic and phytosociological composition on a stretch of dense “Terra Firme” rainforest located in the Belo Monte hydroelectric plant area of influence, located in the state of Pará, Brazil. All trees with DAP > 10 cm situated in 75 permanent plots of 1 ha were inventoried. 27,126 individuals trees (361 ind.ha-1), distributed in 59 botanical families, comprising 481 species were observed. The families with the largest number of species were Fabaceae (94), Araceae (65) and Arecaceae (43), comprising 43.7% of total species. The species Alexa grandiflora (4.41), Cenostigma tocantinum (2.50) and Bertholletia excelsa (2.28) showed the highest importance values (IV). The ten species with greater IV are concentrated (22%). The forest community has high species richness and can be classified as diverse age trees, heterogeneous and of medium conservation condition. © 2015, Instituto Internacional de Ecologia.

Brachycephalus (Anura: Brachycephalidae) is a remarkable genus of miniaturized frogs of the Brazilian Atlantic Rainforest. Many of its species are highly endemic to cloud forests, being found only on one or a few mountaintops. Such level of microendemism might be caused by their climatic tolerance to a narrow set of environmental conditions found only in montane regions. This restriction severely limits the chance of discovery of new species, given the difficulty of exploring these inaccessible habitats. Following extensive fieldwork in montane areas of the southern portion of the Atlantic Rainforest, in this study we describe seven new species of Brachycephalus fromthe states of Paraná and Santa Catarina, southern Brazil. These species can be distinguished from one another based on coloration and the level of rugosity of the skin in different parts of their body. These discoveries increase considerably the number of described species of Brachycephalus in southern Brazil. © 2015 Ribeiro et al.

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.

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.

Pleurodema bibroni is a leiuperid frog known from open habitats in Uruguay and Southern Brazil. This paper provides the first record from state of Paraná, Brazil, and extends the distribution of the species approximately 250 km northwest from the nearest record. The specimen was found in Refúgio de Vida Silvestre dos Campos de Palmas, a federal reserve in southwestern Paraná state created to protect the grasslands, and represents an important record, since the species is considered to be Near Threatened according to IUCN criteria. © 2014 Check List and Authors.
