1. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

2. Floristic-functional variation of tree component along an altitudinal gradient in araucaria forest areas, in Southern Brazil
ABSTRACT We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and de

3. Pathways affect vegetation structure and composition in the Atlantic Forest in southeastern Brazil
ABSTRACT Although impacts generated by gaps can affect vegetation, few studies have addressed these impacts in the Atlantic Forest. Our aim was to investigate the effects of pathways of varying widths on vegetation structure and composition, considering dispersal syndromes, diversity, life forms, successional categories and threatened and exotic species occu

4. 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

5. Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing t

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. Litter production and seed rain in semideciduous forest fragments at different successional stages in the western part of the state of Paraná, Brazil
We documented litter production and seed rain in fragments of semideciduous forest (SDF) in the western part of the state of Paraná, Brazil: a late successional fragment (LF); an early successional fragment (EF); and a reforested late successional fragment (RLF). In each fragment, we established three permanent plots with four litter traps each, correspondi

8. Partitioning of seed dispersal services between birds and bats in a fragment of the Brazilian Atlantic Forest
Community-level network studies suggest that seed dispersal networks may share some universal properties with other complex systems. However, most of the datasets used so far in those studies have been strongly biased towards temperate birds, including not only dispersers, but also seed predators. Recent evidence from multi-taxon networks suggests that seed

9. CHUVA DE SEMENTES EM REMANESCENTE DE CAATINGA NO MUNICÍPIO DE PORTO DA FOLHA, SERGIPE BRASIL. / SEED RAIN IN REMAINING IN THE CITY OF PORT CAATINGA LEAF, SERGIPE - BRAZIL.
As florestas tropicais secas apresentam uma grande diversidade biológica e estudos sobre os mecanismos de dispersão e chuva de sementes proporcionam informações valiosas sobre padrões de dispersão, entradas e saídas de diásporos que atuam no processo de regeneração natural em ambientes preservados e/ou degradados, assim como na abundância, distrib

10. Dispersal Syndromes of fossil Seeds from the Lower Permian of Paraná Basin, Rio Grande do Sul, Brazil
A Análise morfológica das sementes tem sido um importante objeto em estudos ecológicos modernos, uma vez que fornece evidências sobre a biologia e as adaptações das plantas-mãe de sementes. Entretanto, este tipo de estudo tem sido restrito a ecologia de plantas modernas e é raramente utilizado em interpretações de dados paleozóicos. A partir do en

11. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

12. Dispersal syndromes related to edge distance in cerrado sensu stricto fragments of central-western Brazil
As principais forças seletivas que afetam as estratégias de frutificação estão relacionadas ao ambiente em que as plantas ocorrem. Como fragmentos de cerrado sensu stricto são savânicos, as condições microclimáticas não devem variar em relação à distância da borda. Assim, postulamos que a importância das diferentes síndromes de dispersão n�
