| 1.Community assembly theory assumes that ecological communities are spatially delimited into patches. Within these patches, coexistence results from environmental filtering, competition, and immigration. Truly delineated communities exist in laboratory studies of microbial cultures in Petri dishes, yet empirical tests conducted in continuous environments often use patches defined by convention as opposed to realised boundaries. 2.Here we perform a test of ecological community assembly rules using foliar endophyte communities from a tropical rainforest, where leaves are considered as patches for both fungal and bacterial communities. We determined the diversity of fungal and bacterial endophytes using environmental DNA sequencing of 365 top‐canopy leaves,... |

| Abstract: We provide information on the diversity and natural history of anurans from preserved and disturbed habitats in the region of Etá Farm, municipality of Sete Barras, state of São Paulo, Brazil. The region is covered by rainforest and plantations of banana and peach palm. From April, 2013 to March, 2014 we sampled amphibians mainly with pitfall traps with drift fences and visual and auditory surveys. A total of 9813 individuals of 36 species of anurans from nine families were recorded in this study. A larger number of species was found in forests (29 species), followed by peach palm plantations (21 species), and banana plantations (17 species). The areas of peach palm plantation and forests showed the greatest similarity in species composition. The... |

| Lamington National Park in Queensland, Australia is noted for its rainforest and is part of Australia’s fourteen World Heritage listed properties but no systematic study has been done of the importance of birds to its visitors. This study rectifies this situation. It is based on data from survey forms handed to visitors at an important site in this park and completed by visitors following their visit. This yielded 622 useable replies. These enabled us to establish the comparative importance of birds as an attraction to this site. Furthermore, logit regression is used to analyze and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction. In addition, the relative importance to visitors of various... |

| Measuring leaf gas exchange from canopy leaves is fundamental for our understanding of photosynthesis and for a realistic representation of carbon uptake in vegetation models. Since canopy leaves are often difficult to reach, especially in tropical forests with emergent trees up to 60 m at remote places, canopy access techniques such as canopy cranes or towers have facilitated photosynthetic measurements. These structures are expensive and therefore not very common. As an alternative, branches are often cut to enable leaf gas exchange measurements. The effect of branch excision on leaf gas exchange rates should be minimized and quantified to evaluate possible bias. We compared light‐saturated leaf net photosynthetic rates measured on excised and intact... |

| In this study we analyzed the diet of the gymnophthalmid lizard Ecpleopus gaudichaudii Duméril & Bibron, 1839, a typical inhabitant of the forest-floor leaf litter, in an Atlantic Forest area in the state of Rio de Janeiro, southeastern Brazil. The 26 individuals sampled during the study had a mean snout-vent length (SVL) of 36.2 ± 4.2 mm and a mean jaw width (JW) of 4.1 ± 0.5 mm. We did not find differences in SVL between males and females, though the sexes differed in JW when the effect of body size was factored out, with females presenting higher values. The diet of the lizards was composed exclusively of arthropods, especially isopods and orthopterans. The similarity in trophic niches among seasons (volumetric and numerical proportions of prey... |

| ABSTRACT Bats of the subfamily Desmodontinae are the only hematophagous mammals, represented by three species. Among them, Diaemus youngii has the fewest records in Brazil, being poorly known demographically and ecologically. We report the first record of D. youngii for Mato Grosso state, in central-western Brazil, and provide additional records for the states of Rondônia and Tocantins, in northern Brazil, extending the known distribution of D. youngii in the southern Amazon region. |

| The known distribution of Perichaena calongei, P. chrysosperma, P. corticalis, P. depressa, P. microspora, P. pedata and P. vermicularis in the nine states that comprise Brazil's Northeast Region (1,548,672 km2) is presented herein, enhancing our understanding of the distribution of the genusPerichaena (Trichiaceae, Myxomycetes) in the Neotropics. This inventory encompasses a 100-year period (1914-2014), and analyzes material deposited in herbaria and collected by the authors. The collected material came from areas of thorny deciduous vegetation typical of the Caatinga biome and portions of savannah in the continent's interior, rainforests,restingas (tropical moist broadleaf forests found along Brazil's coastal spits) and mangroves of the Atlantic Forest... |

| Gracilinanus emiliae is a species of gracile mouse opossum that is currently known from fewer than a dozen specimens. The material we examined exhibits a distinctive suite of external and craniodental characters that are unlike those of any other congeneric species. We review all published records for G. emiliae, several of which are based on misidentifications or lost material, and we report a new specimen from northeastern Peru, the first to be recorded from that country, and the first to be unequivocally associated with primary lowland rain forest. The available distributional data suggest that G. emiliae (or a complex of cryptic taxa with the same morphological characters) is very widely distributed in Amazonia and perhaps also in Venezuelan coastal... |

| Reintroduction has been recognized as a powerful conservation tool, but in order to ensure its success, animal monitoring is highly recommended. One way to monitor released animals is to put radiotelemetry collars on them. These devices, however, can harm the subjects, causing serious wounds. Our objectives in this work were to describe the injuries caused by a radiotelemetry collar model on reintroduced agoutis and to propose modifications to it. We equipped agoutis with TXE-311C radio collars (Telenax Wildlife Telemetry) before releasing them in the wild. They acquired serious wounds and one animal died. We then modified the collar structure to reduce its width and retention of water. After these modifications, the injuries did not occur again. As... |

| ABSTRACT Lophostoma carrikeri has been mostly recorded within the Amazon biome. There are scarce records in the northern Brazilian Amazon, but also records outside this biome, which were neglected in literature. The aim of this study was to update and extend the distribution of L. carrikeri. Seven new localities in Brazil were provided, including the first records for the states of Rondônia and Mato Grosso, filling a large gap in the species distribution, and three additional records for the state of Pará. Our results reinforce the notion that L. carrikeri is widely distributed in the Amazon, but is also present in other biomes in Brazil, such as Caatinga, Cerrado, and transitional areas. |

| Abstract Malaria elimination is now set to occur in Brazil until 2030. While this achievement is feasible, as it is for other endemic regions worldwide, it is important to recognize resistance of parasites and vectors against anti-malarial interventions. Resistance against drugs and insecticides can lead to discontinuities of malaria transmission, known as residual malaria transmission. Herein, we described a novel phenomenon that is occurring in a residual malaria transmission scenario in the southeastern Atlantic forest. This novel phenomenon does not belong to what is known and therefore we decided to explain it based on an evolutionary perspective. Although it shall not be viewed as a threat to public health, the phenomenon has important aspects that... |
