25. Gene pool sharing and genetic bottleneck effects in subpopulations of Eschweilera ovata (Cambess.) Mart. ex Miers (Lecythidaceae) in the Atlantic Forest of southern Bahia, Brazil
Abstract Forest loss and fragmentation are the main threats to the maintenance of the Atlantic Forest, an important global biodiversity hotspot. Because of the current critical level of deforestation, ecological corridors are needed to facilitate species dispersion and gene flow among fragments. This study was conducted to investigate the genetic variability

26. Diametric Growth of Tree Species in the Atlantic Forest, Paraná, Brazil
Abstract: Management of remnants in Atlantic Forest is an alternative for their conservation, however, information on the growth and ecology of those species is lacking. This study aimed to describe diametric growth of Balfourodendron riedelianum, Cordia trichotoma and Ocotea diospyrifolia based on its growth rings and to verify the relationship between this

27. Helechos y Licofitas de la Reserva de Biosfera Yabotí, Misiones, Argentina: Parque Provincial Moconá
Abstract Abstract The Parque Provincial Moconá is in the east of the Misiones province, surrounded by Yabotí and Uruguay rivers. It belongs to Yabotí Biosphere Reserve, and together with other Biosphere’s protected areas, it represents one of the main relicts of the Paranaense forest in the country. In this work, fern and lycophyte species that grow in

28. Anthropic disturbances as the main driver of a semideciduous seasonal forest fragment in Minas Gerais
Resumo As novas condições ambientais impostas por eventos de distúrbios criam um mosaico de manchas em diferentes estágios sucessionais. Nosso objetivo foi descrever a variação temporal de uma floresta estacional semidecidual em função do histórico de perturbação antrópica, verificando possíveis mudanças na dinâmica e estrutura da floresta.

30. Roadkilled mammals in the northern Amazon region and comparisons with roadways in other regions of Brazil
RESUMO As rodovias e o fluxo de veículos contribuem para os processos de fragmentação da paisagem e alteração do habitat natural, representando ameaça para conservação das espécies em diversos biomas. Este estudo avalia os registros de atropelamentos das espécies de mamíferos silvestres e compara este com outros 37 estudos realizados no Brasil, pa

31. Use of microhabitats affects butterfly assemblages in a rural landscape
Abstract Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how

33. Extension of the geographic distribution of Plecturocebus baptista (Pitheciidae, Primates) and a possible hybrid zone with Plecturocebus hoffmannsi: evolutionary and conservation implications
RESUMO Macacos zogue-zogue (família Pitheciidae) são primatas neotropicais altamente diversificados em morfologia, ecologia e genética, com distribuição geográfica abrangente, incluindo a Floresta Amazônica, Mata Atlântica, Cerrado, Pantanal e a Caatinga. Essa diversificação, juntamente com lacunas de conhecimento, gera incertezas na taxonomia e di

34. Homegardens as a System for Restoration of Legal Reserves: Aspects of Forest Legislation
ABSTRACT The homegardens result from collective learning and fulfill environmental services, contributing to the agrobiodiversity conservation and food security. The present study analyzed whether legal mechanisms incorporate concepts on environmental services and if legal frameworks in the state of São Paulo include homegardens as a feasible system for res

35. Biodiversity Conservation in Agricultural Landscapes: the Importance of the Matrix
ABSTRACT Agricultural matrices can lead to landscape homogenization, culminating in losses of biodiversity and ecosystem services. Agricultural management is determinant for developing conservation strategies. In this review, we discuss the influence of the agricultural matrix on biodiversity at different scales. Intensive agriculture under agrochemicals and

36. Grassland vegetation sampling - a practical guide for sampling and data analysis
ABSTRACT Grassland and savanna ecosystems are the original vegetation types of more than 30% of the Brazilian territory, but conservation and training of future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland vegetation for environmental planning or licensing. Neglecting non-forest ecosystems may have
