1. Frugivoria por aves em quatro espécies de Cactaceae na Caatinga, uma floresta seca no Brasil
RESUMO As aves são conhecidas por desempenharem um importante papel na reprodução de diversas espécies de plantas através da frugivoria e dispersão de sementes. Apesar da importância das cactáceas em ambientes sazonais, poucos estudos avaliaram interações entre essas plantas e aves frugívoras. O presente trabalho identificou as espécies de aves q

2. The phyllostomid bat (Mammalia, Chiroptera) assemblage in a fragmented landscape in Midwestern Brazil
RESUMO Os morcegos são a segunda maior ordem de mamíferos, com diversos hábitos alimentares e grande importância ecológica. A antropização possui diversos efeitos nas comunidades animais e o Cerrado Brasileiro, uma savana neotropical, tem sido severamente afetada pela atividade humana. O objetivo deste estudo foi avaliar a distribuição da assembleia

3. 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

4. Reproductive phenology, seed removal and early regeneration in relation to distance from parental plants of a native palm in small Atlantic forest fragments
ABSTRACT The Brazilian Atlantic Forest is a global biodiversity hotspot, but most of what remains are small fragments. Small fragments are often harsh environments for forest plant recruitment due to edge effects and the loss of frugivorous animals that provide seed dispersal. We recorded the one-year reproductive phenology of the keystone palm Syagrus roman

5. Dispersión de semillas de Mauritia flexuosa (Arecaceae) por frugívoros terrestres en Laguna Azul, Beni, Bolivia
Scatterhoarding has received special attention for the last couple of decades, and several studies focused on palms whose seeds are dispersed by Dasyprocta. Our objective was to know the species that consume fruits of Mauritia flexuosa, to evaluate the relative importance of consumer species, and also to assess the fate of dispersed seeds. Using field experi

6. 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

7. 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

8. Comunidades de aves frugívoras e nectarívoras e disponibilidade de recursos em dois estádios sucessionais de regeneração de Mata Atlântica.
The availability of food resources in different degrees of regeneration of a forest may contribute to possible variations in species abundance and composition of bird communities. The main objective of this study is to investigate the relationship between the structure of frugivores and nectarivores bird communities and the availability of food resources - f

9. The role of seed mass on the caching decision by agoutis, Dasyprocta leporina (Rodentia: Agoutidae)
It has been shown that the local extinction of large-bodied frugivores may cause cascading consequences for plant recruitment and overall plant diversity. However, to what extent the resilient mammals can compensate the role of seed dispersal in defaunated sites is poorly understood. Caviomorph rodents, especially Dasyprocta spp., are usually resilient frugi

10. Interactions etween ants, fruits and seeds in the cerrado : the role of ants in the biology of seeds and seedlings / Interações entre formigas, frutos e sementes em solo de cerrado : o papel de formigas na biologia de sementes e plantulas
Our knowledge about seed dispersal systems has been improved considerably in the last few years. An increasing number of studies has shown that the process of plant regeneration is often much more complex than we realize, including several different agents across subsequent steps of seed dispersal. For instance, ants may reshape the seed shadow after seeds f

11. Interações entre o morcego Sturnira lilium (Chiroptera: Phyllostomidae) e plantas da família Solanaceae / Interactions between the bat Sturnira lilium (Chiroptera: Phyllostomidae) and plants of the family Solanaceae
Bats have a high ecological importance in the Neotropics for they are highly diverse, very abundant and interact with many plant and animal species. Phyllostomid bats of the subfamily Stenodermatinae are specialized frugivores and important seed dispersers, and Sturnira lilium prefers fruits of the Solanaceae, a family of high ecological and economical value

12. Estrutura etária e distribuição espacial de Myrcianthes pungens (O. Berg) Legrand (Myrtaceae) em um trecho de mata ciliar do rio da Prata, no município de Jardim, Mato Grosso do Sul
The objective of this study was to evaluate the size structure and spatial distribution model of the arboreal species Myrcianthes pungens (O. Berg) Legrand, (Myrtaceae). This is a climax, shade-tolerant semideciduous species, which is distributed from the states of Mato Grosso do Sul and São Paulo to the northern Uruguai. It is actually classified as a thre
