| Abstract: The orchid seed banks of Atlantic Forest may be considered a key strategy for the conservation of species threatened with extinction by indiscriminate collection or habitat destruction. The aim of this study was to evaluate the seed viability, to choose the best culture medium for the asymbiotic germination and evaluate germination, after storage for different periods and temperatures for the Brazilian native orchids: Gomesa praetexta (Rchb.f.) M.W.Chase & N.H.Williams, Gomesa forbesii (Hook.) M.W.Chase & N.H.Williams, Gomesa recurva R.Br. and Grandiphyllum divaricatum (Lindl.) Docha Neto. Knudson C (KC), Murashige & Skoog (MS), half-strength MS (1/2 MS macro- and micro-nutrients) and Woody Plant Medium (WPM) culture media were tested... |

| Abstract: The Tinguá Biological Reserve (TBR) is the largest protected area of this category in Rio de Janeiro state. Here, for the first time, we present the historical composition of terrestrial mammals' assemblage of TBR region. An inventory was conducted using transect surveys, nonstandard transects, survey of museum specimens and informal reports. Considering all the data, eighty-five species were recorded, placing TBR as the second one in the number of mammals recorded in "Serra do Mar" ecoregion of Atlantic Forest and in the Rio de Janeiro state. Among the species with historical records are the jaguar (Panthera onca) and the golden-lion-tamarin (Leontopithecus rosalia) while the current presence of the maned wolf (Chrysocyon brachyurus) was... |

| Little is known about the ichthyofauna from South American coastal plain, specially concerning the Mata Atlântica (Atlantic Forest) rivers and streams, as there are regions little explored which may have non-described or rare species. An example is the Parque das Neblinas, a Natural Patrimony Private Reserve (RPPN) in the Bertioga municipality, São Paulo state, where no ichthyofaunal study had been done before. The park's hydrography is made up by the rio Itatinga with its various tributary streams, which flow into the Itapanhaú river basin. Nine sites were sampled using sieves, seines and gill nets; 1,086 specimens of seven species, three orders and five families were captured. The most representative species were Astyanax paranae, Phalloceros... |

| The IUCN Red List is an important conservation tool. Although its criteria are used worldwide, in most cases the classification process per se is restricted to a group of experts with restricted or no participation of the general public. This may raise concerns from final Red List users, which, without knowing the data or procedures adopted by the experts, may argue on the outcomes, final classification adopted, or the overall use of the lists. IUCN recommends that all assessments must be backed up by data and justifications, making them as accurate and transparent as possible. We describe here the assessment of Eptesicus taddeii, a bat species endemic to the southern Atlantic Forest of Brazil, indicating how and why the species was flagged as Vulnerable -... |

| Medium and large-sized terrestrial mammals develop important functions in ecosystems maintenance. However, this group is the most vulnerable to local extinctions, through habitat loss or hunting. This study inventoried the community of medium and large mammals in the Reserva Ecológica de Guapiaçú (REGUA), Cachoeiras de Macacu, RJ, providing data on species composition, richness and abundance. Species were registered through the use of camera traps, sign survey and visual encounters on pre-existing trails and roads. The study was conducted from January to October 2012, with each month considered as a sample unit. An effort of 1568 cameras-day and 120 km traveled, resulted on 302 records of 22 species of medium and large-sized mammals, belonging to eight... |

| Caesalpinia echinata Lam. (brazilwood) is an endangered tree species occurring along the eastern coast of Brazil from latitudes 5°56´S to 22°56´S. With such a range of distribution it is expected that temperature and daylength may affect plant development, which was examined in this study. One- and five-year-old saplings were grown under controlled photoperiods of 8 h, 12 h and 20 h, and in a greenhouse under natural light during 16 months. In another experiment, one-year-old saplings were cultivated for six months in a growth cabinet, with reduced maximum temperature, and in the greenhouse. Leaf number, stem height and stem diameter at the soil surface were evaluated every two months (experiment 1) or every month (experiment 2). In experiment 1, no... |

| Beilschmiedia berteroana ("belloto del sur") is a screrophyllous tree of the family Lauraceae that is endemic to the Central-South region of Chile. It is an endangered species; considered a second priority in the "Extinction Danger" category. This species is known for its timber, fruits and lots of mucilages, also has great potential for its size and ornamental evergreen foliage. This study had as a main objective to develop an in vitro rooting protocol of microshoots, obtained from the proliferation phase, by adding auxin: indole 3-butyric acid (IBA), naphthaleneacetic acid (NAA) and indole 3-acetic acid (IAA) in order to contribute to the recovery of the species. Results are discussed in the rooting phase, where this species is induced or maintained in... |

| ABSTRACT Campomanesia rufa (O. Berg) Nied. is a native Cerrado species that presents great edible potential. However, it is a species “in danger of extinction” as recommended by the International Union for the Conservation of Nature (IUCN). No technical and scientific information about the species exists, thus demonstrating the importance of its research. The present work aimed at the physical and chemical characterization of immature and mature C. rufa fruits. The fruits showed a change in coloration from green (b * = 25.11, h = 122.43) to yellowish-green (b * = 34.26 , h = 115.73), an increase in mass (6.54 g to 10.88 g), diameter (23.76 mm to 28.03 mm) and soluble solids (8.00 to 10.80%). The fruits presented high levels of total (1246.35 mg 100 g-1)... |
