| Cabralea canjerana subsp. canjerana is a common species in the Atlantic Forest, occurring in several areas of this biome. Yet, little is known about its reproductive strategies. This study aims to understand the reproductive biology of this subspecies, including floral biology, sexual system, and pollination biology. Male and female plants have morphologically similar flowers, but male plants have larger inflorescences with more flowers than female plants. Female flowers remain open and receptive for two days, whereas male flowers last only one day; thus, compensating for the imbalance of the number of flowers per plant between the two sexes. Morphologically similar male and female flowers, as observed in C. canjerana subsp. canjerana, are rare among... |

| In a survey of Agaricales fungi in Seasonal Semidecidual Forest remnants from Paraná State, southern Brazil, two Clitocella and two Rhodocybe species were identified. Based on morphological data, Clitocella pallescens is described as a new species, and a new combination is proposed to Clitocella himantiigena. Rhodocybe galerinoides and C. himantiigena are new records from Brazil. Rhodocybe caelatoidea, already registered in Paraná State, is also described, illustrated and discussed. |

| For many years, tropical and subtropical forests have been deforested for agriculture, grazing, and timber extraction. Nevertheless in the last decade, several publications have suggested that some regions of Latin America are showing a process of forest transition. Forest transition theory predicts that industrialization and urbanization will lead to the abandonment of marginal agriculture lands and the recovery of natural systems such as forests. However, there are many ecological, economic, and social factors that could act as barriers to ecosystem recovery. To evaluate this hypothesis, we analyzed the socioeconomic and land-use changes during the last 30 years at the provincial and departmental level in the province of Misiones, Argentina. We... |

| Abstract Psidium cattleyanum Sabine is an Atlantic Forest native species that presents some populations with red fruits and others with yellow fruits. This variation in fruit pigmentation in this species is an intriguing character that could be related to species evolution but still needs to be further explored. Our goal was to provide genomic information for these morphotypes to understand the molecular mechanisms of differences in fruit colour in this species. In this study, we performed a comparative transcriptome analysis of red and yellow morphotypes of P. cattleyanum, considering two stages of fruit ripening. The transcriptomic analysis performed encompassing leaves, unripe and ripe fruits, in triplicate for each morphotype. The transcriptome... |

| The purpose of this work was to determine the diversity and population fluctuations of calliphorid flies in the Biological Reserve of Tinguá (ReBio-Tinguá), Nova Iguaçu, state of Rio de Janeiro, Brazil and to correlate their occurrence with the environmental variables of temperature, rainfall and relative air humidity. Specimens of Diptera were collected monthly between June 2002 and January 2005 using four traps placed at four points along a trail and exposed for 48 hours. The traps were baited with sardines and the trapped insects were stored in 70% alcohol. It was collected 8,528 calliphorids, thirteen species were identified among the blowflies including Laneela nigripes Guimarães 1977, Chrysomya megacephala (Fabricius, 1794), C. albiceps (Wiedemann,... |

| Aedes (Stegomyia) albopictus (Skuse, 1894) larvae were recorded for the first time in the internodes of bamboo cuts found in the Atlantic Forest in the State of Paraná, Brazil. The bamboo, Bambusa sp., was introduced in the area of Imbucuí-Mirim town, across the municipal district of Paranaguá and towards the interior of the Atlantic Forest. A total of 251 larvae of Aedes albopictus (37.9%), Culex (Microculex) spp. (13.9%), Limatus durhami Theobald, 1901 (39.8%), Toxorhynchites sp. (0.4%) and Wyeomyia spp. (8.0%) were collected from bamboo internodes filled with rain and from the terrestrial Bromeliaceae and epiphytas found near the bamboo bushes. Aedes albopictus was found in bamboo internodes containing 30 to 254 ml of rain, sometimes coexisting with Li.... |

| ABSTRACT Many studies have demonstrated the ecological relevance and great biodiversity of bats in Brazil. However, mountainous areas have been disproportionately less sampled, mainly in the Southeast. The aim of this study was to identify and compare the richness and diversity of Phyllostomidae, the most diverse bat family, in different forest types in Parque Estadual do Ibitipoca, trying to understand the causes of possible differences. The Parque Estadual do Ibitipoca is inserted in the Serra da Mantiqueira's domain, in an Atlantic Forest region known as "Zona da Mata", state of Minas Gerais, with an altitudinal range between 1200-1784 meters. The study was conducted in two forest types, classified as "Nanofloresta Nebular" and "Floresta Nebular", whose... |

| A survey of carnivore mammals was accomplished in Aparados da Serra National Park from February 1998 to March 2000. The park has 10,250 ha and is considered a biodiversity core area of the Atlantic Forest Biosphere Reserve in the Rio Grande do Sul State, Brazil. The landscape is characterized by relatively well preserved relicts of Araucaria angustifolia (Bertol.) Kuntze forest, grasslands and Atlantic Forest, which have contributed for the survival of endangered carnivore mammals. The National Park was divided in a grid of 16 km² cells using a 1:50,000 scale map. The animals were recorded using indirect methods, by identifying signs (scats, tracks) and direct observation in 2.5 km long and 5 m wide transects, with 10 replicates in each grid cell.... |

| ABSTRACT The Atlantic Forest has been highly fragmented, with the Pernambuco Center of Endemism (PCE) one of the priority areas for conservation. The Mata do Cedro forest, located in Alagoas state, northeastern Brazil, is a forest fragment within the PCE surrounded by a matrix of sugarcane that acts as a refuge for several threatened bird species, some of which are endemic to the region. Here, we characterize the bird community in Mata do Cedro using measures of species abundance, frequency of occurrence, habitat use and sensitivity to human disturbance. The functional role of species was investigated with a functional dendrogram. We registered 111 species, most resident and forest dependent. The most representative trophic categories were insectivores... |

| ABSTRACT Physiological reorganization is described for the first time for the hypotrich ciliate genus Apoamphisiella Foissner, 1997, based on a population of A. vernalis (Stokes, 1887) Berger, 2006 collected from an eutrophic pond in the state of Minas Gerais, Brazil. Stomatogenesis is epiapokinetal, and the cirral pattern reorganizes from six typical fronto-ventral-transverse primordia, plus at least one short primordium located between IV and V. Primordia I and II originate from disaggregating undulating membranes and buccal cirrus, respectively; primordium III originates from left frontoventral cirrus plus a streak of basal bodies extending from the anterior end of oral primordium; primordium IV and the short extra primordia are formed from basal bodies... |

| Bromeliad-associated mosquitoes (Diptera: Culicidae) in Atlantic Forest in Florianópolis, Santa Catarina, southern Brazil, were studied, examining plants of Vriesea philippocoburgi Wawra and Aechmea lindenii (E. Morren) Baker var. lindenii at secondary Atlantic rain forest, and A. lindenii and Vriesea friburgensis Mez var. paludosa (L. B. Smith) at "restinga" per month, during 12 months. No immature forms of mosquitoes were collected from A. lindenii in the secondary forest. Collections obtained 368 immature mosquitoes, none of them from A. lindenii from rain forest. Culex (Microculex) spp. constituted 79.8% of the total, Wyeomyia (Phoniomyia) spp. 17.93%, and Anopheles (Kerteszia) cruzii (Dyar & Knab, 1908) only 1.36%. The study shows the great... |

| ABSTRACT We analyzed the bat assemblages found in protected areas in the state of Rio de Janeiro, Brazil, which is the best-sampled region of the Atlantic Forest. We selected 24 strict nature reserves and nine sustainable-use protected areas. We used data from inventories and complemented with data from the literature. We compared strict and sustainable-use protected areas, and tested whether the bat assemblages varied between habitat types. We tested the effect of geographic distance on the dissimilarity between bat assemblages, as well as the relationship between species composition and the size, mean altitude of the protected area, and capture effort. We compiled a total of 34,443 capture records, involving 67 species. Three species were captured only... |
