We provide a list of amphibian and squamate species collected in the Raso da Catarina Ecological Station, Bahia state, Brazil, during two distinct periods. An initial visual inventory of amphibians was conducted monthly from March 2010 to February 2011, using transects in a forest and temporary ponds. The second inventory was conducted over a 30-day period between March and April, 2012, when 37 pitfall trap arrays, each consisting of four buckets and supplementary glue traps, were set in low scrub and forest, complemented by opportunistic searches. A total of 19 lizard species, two amphisbaenians, 21 frogs, and 11 snakes were recorded during the study. New records for the protected area include 10 lizards, one amphisbaenian, 15 amphibians, and 11 snakes (36 species in total). Several species typical of the Atlantic Forest were collected, reflecting the potential influence of this biome, especially in the sampled forest habitats (Mata da Pororoca).

<p>The Atlantic Forest, which has a vast epiphytic richness, is a priority area for preservation, listed as one of the five most important world hotspots. Vascular epiphyte richness, composition and community structure were studied in two fragments, one of the ombrophilous (29º43'42"S and 50º22'00"W) and the other of the seasonal (29º40'54"S and 51º06'56"W) forest, both belonging to the Atlantic Forest biome in the Sinos River basin, Rio Grande do Sul, Brazil. In each fragment, 40 trees, divided into four ecological zones, were analyzed. In each zone, the occurrence of the species was recorded, and the importance value of each species was calculated according to the frequency of phorophytes and intervals, and cover scores. The Shannon index was calculated for the two communities. In the fragment of the ombrophilous forest (F1), 30 epiphytic species were recorded, and in the seasonal forest (F2), 25. The highest importance value was found for <italic>Microgramma squamulosa</italic> (Kaulf.) de la Sota in both fragments. The diversity indexes for F1 (H'=2.72) and F2 (H'=2.55) were similar and reflected the subtropical location of the areas. The decrease in mean richness in both fragments in zone 3 (internal crown) to zone 4 (external crown) may be associated with time and space availability for epiphyte occupation and microclimate variations. Exclusive species were found in the areas, which suggest that a greater number of preserved fragments may result in a greater number of preserved epiphytic species in the Sinos River basin.</p>

ABSTRACT This paper synthesises a decade of research on a swamp forest within the Atlantic forest complex in the state of Rio de Janeiro, Brazil. I propose that this swamp is a fragile ecosystem, since its diversity and functioning are highly dependent on a specific interaction between two functional groups: shade-providers (locally rare trees) and providers of safe germination sites (terrestrial bromeliads). This conclusion is based on a broad set of data regarding plant ecophysiology, population and community ecology and phytogeography, which I review here. I discuss the implications of these findings for conservation and restoration of swamps at the Atlantic forest complex.

Here, we propose Uanauna gen. nov. (Lampyridae: Photinini), a new monotypic genus of fireflies endemic to the Brazilian Atlantic Forest. Uanauna angaporan sp. nov. occurs in Submontane and Montane forest habitats at the Serra do Mar mountain range, in the Southern Fluminense region (Rio de Janeiro State, Southeastern Brazil). The new species was recorded both on the mainland, at the municipality of Itaguaí and Rio de Janeiro, and at the continental island of Ilha Grande, in Angra dos Reis, at the Rio de Janeiro State. An occurrence map and illustrations of diagnostic features are given for the new taxa, as well as a key to Lucidotina genera in Brazil.

AbstractThis paper evaluates the ecological consequences of hunting by comparing mammalian densities, biomass, relative energy consumption and community structure between sites with different levels of hunting pressure. Hunting is carried out mainly by colonists who farm on the edge of Atlantic forest fragments in the State of São Paulo, Brazil. Mammals were studied over a period of 18 months, along 2287 km of line transects. Transects were distributed among two protected sites, one slightly hunted site and two heavily hunted sites. Tapirs, the two peccary species, brocket deer, armadillos and agoutis are preferred by hunters in the region. Primates are not hunted in the region. Hunting has affected community structure, with ungulates dominating mammalian biomass at protected sites and primates dominating at hunted sites. This has caused an ecological inversion in the hunted areas of the Atlantic forests. In Amazonian regions of the Neotropics hunting is more evenly distributed among primates, large rodents, and ungulates and has resulted in an opposite inversion, with hunted sites having lower primate biomass. Atlantic forests are very susceptible to the possible ecological imbalances induced by hunting by humans, and this must be considered for management and conservation programmes.
