1. NET PRIMARY PRODUCTIVITY OF A MOUNTAIN FOREST ECOSYSTEM AS AFFECTED BY CLIMATE AND TOPOGRAPHY
ABSTRACT Response of terrestrial ecosystems to changing climate has become an issue of central importance for land managers and policymakers. Climate extremes and trends have a strong control on productivity of semi-arid mountain ecosystems. Located in a transition zone from continental type climate to relatively mild Black Sea type climate in Turkey, the Il

2. Emerging hotspots of tree richness in Brazil
ABSTRACT We present a summary of floristic variation and distribution of richness of tree and tree-like taxa (i.e., freestanding plants that reach at least 3m in height) in Brazil. We investigated composition patterns throughout phytogeographic domains and vegetation types based on 698,490 occurrence records obtained from the NeoTropTree (NTT) database, and

3. Hysterosalpingography: Balloon Catheter or Metal Cannula?
ABSTRACT The Brazilian Atlantic Forest (BAF) is one of the biodiversity hotspots, but in the last decades, it has been fragmented due to agricultural and urban-industrial expansion, which has a strong impact on forest fragments. The goal of this study was to analyze the Biotic Integrity Index (BII) in fragments of BAF in two medium-sized cities in Southeaste

4. IS BIOTIC INTEGRITY OF URBAN FORESTS REMANTS RELATED WITH THEIR SIZE AND SHAPE?
ABSTRACT The Brazilian Atlantic Forest (BAF) is one of the biodiversity hotspots, but in the last decades, it has been fragmented due to agricultural and urban-industrial expansion, which has a strong impact on forest fragments. The goal of this study was to analyze the Biotic Integrity Index (BII) in fragments of BAF in two medium-sized cities in Southeaste

5. Drivers of floristic variation in biogeographic transitions: insights from the ecotone between the largest biogeographic domains of South America
ABSTRACT Ecological transitions usually represent vulnerable ecosystems and high biodiversity. Investigating their drivers is important from both biogeographic and conservationist perspectives. One of these transitions is situated between the two largest biogeographic domains of South America - the Amazon and the Cerrado. We evaluated variation in tree flori

6. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

7. Bryophyte flora of the Apodi Plateau, Ceará, Brazil
Resumo No estado do Ceará, as principais áreas amostradas com relação às briófitas são constituídas de encraves úmidos e subúmidos, remanescentes da Mata Atlântica. Estudos em áreas de Caatinga são praticamente inexistentes. O presente trabalho objetivou realizar um inventário florístico das briófitas da Chapada do Apodi, dentro dos limites d

8. Análise das mudanças na vegetação nativa da apa Lago de Palmas
Resumo Neste estudo propõe-se conhecer a dinâmica da vegetação de Cerrado e Floresta Estacional, no período de 2000 a 2017, na Área de Preservação Ambiental (APA) Lago de Palmas, utilizando-se imagens do satélite Landsat e o software livre Spring 5.5.3. Foram construídos dois mapas temáticos da área estudada para estimar, por meio de análise com

9. Mirmecofauna em áreas de preservação permanente e plantios florestais no noroeste do Rio Grande do Sul
Resumo As formigas compreendem um táxon muito diverso de insetos, apresentam elevada riqueza e são ecologicamente importantes nos diferentes ecossistemas terrestres. A riqueza e diversidade de formigas tendem a aumentar de acordo com a complexidade dos ambientes no que se refere à vegetação e ao estágio de conservação da biodiversidade. Este estudo v

10. Multicriterial evaluation in the definition of protected areas at the Piedade municipality, SP.
RESUMO Uma das abordagens utilizadas para mitigar impactos e proteger a diversidade biológica, em longo prazo, é a preservação in situ, por meio do estabelecimento de áreas legalmente protegidas. O município de Piedade apresenta um conjunto de condições favoráveis à consolidação de áreas protegidas (urbanização relativamente baixa, presença d

11. 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

12. 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
