1. Floristic Differentiation of a Deciduous Seasonal Forest Tree Stratum, Jaguari, RS, Brazil
ABSTRACT This study aims at determining and differentiating the floristic groups of a Deciduous Seasonal Forest’s arboreal component, located on the ridge of the Southern Plateau, in Southern Brazil. Individuals with diameter at breast height ≥ 5.0 cm were sampled in sixty-two plots measuring 10 m × 10 m, which were systematically installed in the fores

2. Composition and Functional Diversity of the Urban Flora of Alfenas-MG, Brazil
ABSTRACT Urban tree cover has important environmental and social functions and can act as ecological refuges. The objective of the present study was to investigate the taxonomic and functional diversities of urban plant communities in Alfenas, Minas Gerais State, Brazil. We sampled all trees DBH ≥ 3 cm in eight different urban green areas, recording 1,138

3. Brachionus rotundiformis Tschugunoff, 1921 from the Brachionus plicatilis species complex (Rotifera: Monogononta): A new record from Galápagos Archipelago, Ecuador
Abstract The presence of the rotifer species Brachionus rotundiformis from the B. plicatilis species complex in Lake Arcturo, a saline lake in the Genovesa Island of the Galápagos Islands, is here reported. This is the first record of the species for the rotifer fauna of Ecuador as well as of the species complex to the Galápagos Islands. This finding is co

4. Species diversity, community structure and ecological traits of trees in an upper montane forest, southern Brazil
ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest re

5. How are pollination and seed dispersal modes in Cerrado related to stratification? Trends in a cerrado sensu stricto woodland in southeastern Brazil, and a comparison with Neotropical forests
ABSTRACT A comprehensive census of a hectare of cerrado s.s. in southeastern Brazil, a small-tree and scrub woodland physiognomy, allowed the evaluation of whether pollination and dispersal modes are correlated with the stratification of the vegetation and if so, in what way. Generalist pollination, and pollination by small bees, as well as ornithophily and

6. Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities. We compiled data on pollination and dispersal syndromes of 406 plant species distributed among different elevations in Área de Proteção Ambiental da Serra de Baturité (

7. Ecological aspects of Langsdorffia hypogaea (Balanophoraceae) parasitism in the Pantanal wetlands
Most studies on holoparasitic plants have focused on taxonomic or systematic issues. The objective of this study was to examine the ecological aspects of parasitism of Langsdorffia hypogaea (Balanophoraceae) in the Pantanal wetlands. Individuals of L. hypogaea were dug out by hand and the host trees were identified. Eighty-eight percent of host trees exhibit

8. Estrutura de habitat, diversidade e comportamento da avifauna em sistemas de silvicultura em floresta ombrófila mista
A silvicultura está em franco progresso na América do Sul e as áreas de plantio têm ocupado cada vez mais territórios. No Brasil o conhecimento dos efeitos desta atividade sobre a fauna e flora nativas ainda está em formação e poucos estudos tem sido realizados na Floresta Ombrófila Mista. Os capítulos 1 e 2 discorrem sobre aspectos teóricos envol

9. Pollination and dispersal systems in a Cerrado remnant (Brazilian Savanna) in Southeastern Brazil
The aim of this work was to identify the pollination and dispersal systems among the species in a disjunct marginal cerrado area and to compare the frequency of these systems to those found in other Neotropical vegetation. The floral and diaspore traits and the pollination and dispersal systems of 176 species were analysed in a cerrado remnant in Southeaster

10. Remnant vegetation diagnose aiming forest restoration and conservation in the municipality of Paulínia, São Paulo State / Caracterização da vegetação remanescente visando à conservação e restauração florestal no município de Paulínia - SP
In biological conservation, forest fragmentation is defined as a separation or nonnatural disconnection of wide areas in spatially segregated fragments, generating a reduction of habitat types and the split of remnant habitat in smaller isolated units. The magnitude and extension of these landscape alterations are influenced by size, connectivity, shape, con

11. Chuva de sementes e estabelecimento de plântulas de espécies lenhosas florestais em mosaicos de floresta com araucária e campos no sul do Brasil / Seed rain and seedlind establishment of wood species in mosaics of araucaria forest and campos grassland in southern Brasil
Mecanismos de dispersão de diásporos e de recrutamento de plântulas evitam a competição intra-específica e possibilitam a colonização de novos ambientes, sendo etapas muito importantes para o estabelecimento de populações em novos sítios. Em áreas de transição entre florestas e vegetação campestre esses processos não são aleatórios, e sim

12. Aspectos ecológicos e econômicos do plantio de Pinus elliottii Engelm var. elliottii como facilitadora da restauração de mata ripária em região de Cerrado (Assis, SP, Brasil) / Exotic species in forest restoration: ecological and economical aspects of using Pinus elliottii Engelm var. elliottii as pioneer in Cerrado region, Assis, SP, Brazil
Among the obstacles to the native forests restoration in Brazil we find the high costs of planting high diversity of native trees. Searching for reduction of costs and vegetation recovery acceleration, the use of a fast growing exotic species (Pinus elliottii var. elliottii) as pioneer was tested in a riparian area in the cerrado domain, at Assis municipalit
