1. ASSESSMENT OF GIS-ASSISTED MOVEMENT PATCHES USING LCP FOR LOCAL SPECIES: NORTH CENTRAL ANATOLIA REGION, TURKEY
ABSTRACT As a result of the fragmentation and degradation of forests, the connectivity of natural habitats has been decreasing. Thus, problems in gene flow in wildlife have begun to arise. The connection of landscape patches with corridors is now an important subject of landscape planning. Central Anatolia has been affected by forest fragmentation due to its

2. Potential and Future Geographical Distribution of Eremanthus erythropappus (DC.) MacLeish: a Tree Threatened by Climate Change
ABSTRACT Eremanthus erythropappus is a commercially-important tree which has a long history of exploitation in the Brazilian State of Minas Gerais. The knowledge on the potential geographical distribution of E. erythropappus is therefore critical for the species sustainability. Thus, the aim of this study was to estimate and map current and future ecological

3. Microfósseis não polínicos como indicadores de mudanças ambientais no Holoceno médio da Lagoa Comprida, Parque Nacional da Restinga de Jurubatiba, Estado do Rio de Janeiro, Brasil
RESUMO O trabalho teve como objetivo identificar e descrever a morfologia de microfósseis não polínicos ocorrentes nos sedimentos de um testemunho retirado próximo à barra da Lagoa Comprida, Estado do Rio de Janeiro, Brasil. Foram identificadas oito formas de fungos, dois tipos de algas Chlorococcales em estágio colonial, um tipo de zygósporo de alga

4. The last dinosaurs of Brazil: The Bauru Group and its implications for the end-Cretaceous mass extinction
ABSTRACT The non-avian dinosaurs died out at the end of the Cretaceous, ~66 million years ago, after an asteroid impact. The prevailing hypothesis is that the effects of the impact suddenly killed the dinosaurs, but the poor fossil record of latest Cretaceous (Campanian-Maastrichtian) dinosaurs from outside Laurasia (and even more particularly, North America

5. Fruits and frugivores of the Brazilian Cerrado: ecological and phylogenetic considerations
ABSTRACT Knowing the morphological and phylogenetic patterns of fruits of a plant community may elucidate plant-frugivore interactions, and analysis of dispersal syndromes is a practical approach to understanding these mutualisms. We investigated different zoochorous fruits and frugivorous animals among Cerrado formations (forest, savanna and grassland), map

6. Bryophyte and pteridophyte spores and other palynomorphs in quaternary marine sediments from Campos Basin, southeastern Brazil: Core BU-91-GL-05
This paper presents morphological descriptions and ecological data of cryptogam spores and other non-pollen palynomorphs from Quaternary sediments of Campos Basin, Rio de Janeiro, SE Brazil. The ages were derived from biostratigraphy of planktonic foraminifers and two radiocarbon dates, and suggest that sediment deposition started in the last 140,000 years B

7. Habitat use and movements of Glossophaga soricina and Lonchophylla dekeyseri (Chiroptera: Phyllostomidae) in a Neotropical savannah
The greatest current threat to terrestrial fauna is continuous and severe landscape modification that destroys and degrades animal habitats. This rapid and severe modification has threatened species, local biological communities, and the ecological services that they provide, such as seed dispersal, insect predation, and pollination. Bats are important polli

8. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca

9. Multimetric index for assessing ecological condition of running waters in the upper reaches of the Piabanha-Paquequer-Preto Basin, Rio de Janeiro, Brazil
The objective of this study was to develop a rapid multimetric index using benthic macrofauna as bioindicators of ecological conditions for the upper reaches of the Piabanha-Paquequer-Preto Basin located in the state of Rio de Janeiro, Brazil. A total of 33698 macroinvertebrates were collected in 27 sites. Benthic macroinvertebrates were sampled using the mu

10. Assembléias de diatomáceas em sedimentos holocênicos no estremo sul do Brasil : reconstruções paleoambientais
This paper describes the diatom assemblages present in a sediment profile in the Lagoa do Peixe, Middle Littoral of Rio Grande do Sul, in order to make the palaeoenvironmental reconstruction and identify periods of increased marine influence and hydrodynamics, as a consequence of changes sea level occurred during the Holocene. The drill core T09 was selected

11. A fragmentação da flora nativa como instrumento de análise da sustentabilidade ecológica de áreas protegidas Espinhaço Sul (MG)
Increasing landscape fragmentation has contributed to biodiversity loss in various Brazilian regions and might be associated with unplanned human land occupation. Conservation and survival of most biological communities are dependent upon the spatial restructuring of landscape often limited to government protected areas. This constitutes the main mechanism u

12. ASPECTOS ECOLÓGICOS DO CERVO DO-PANTANAL Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMAIS REINTRODUZIDOS E OU NASCIDOS NA ESTAÇÃO ECOLÓGICA DE JATAÍ, NORDESTE DO ESTADO DE SÃO PAULO, MUNICÍPIO DE LUÍS ANTÔNIO / ECOLOGICAL ASPECTS OF MARSH DEER Blastocerus dichotomus (ILLIGER, 1815) (MAMMALIA: CERVIDAE): ANIMALS REINTRODUCED AND OR BORN IN THE ECOLOGICAL STATION OF JATAÍ, NORTHEAST OF THE STATE OF SÃO PAULO, CITY OF LUIS ANTONIO
Marsh deer (Blastocerus dichotomus) is a large mammal and is considered the largest deer native to South America, this species is extinct in 60% of its historic range that included the natural flood plain of the great rivers between the southern Amazon and northern Argentina. Despite being threatened with extinction, little is known about the ecological aspe
