| The ability of a plant's propagule to reach microhabitats with the adequate conditions for seed germination and sapling establishment will have a direct effect on the plant's fitness. In the case of fleshy-fruited plants, the seeds are dispersed by frugivorous animals. One part of the seed dispersal process is the removal of the fruits, which contain the seeds, from the parental plant. Another important part of the dispersal process is where the seeds land, especially for species with specific light, temperature or humidity needs for germination, such as disturbance colonizers. Solanum riparium (Solanaceae) is a shade intolerant species found in forest gaps within a subtropical montane forest and along river and road edges in North-western Argentina. In... |

| Abstract The frugivorous phyllostomid bat genera Artibeus , Carollia and Sturnira are important seed dispersers in the Neotropics, and exhibit supposed preferences for fruits of the genus Ficus , Piper and Solanum , respectively. We performed a quantified literature review to test the hypothesis that interactions with plants are consistent throughout the bats´ geographic ranges. Through an extensive literature review we obtained a total of 4,448 records of fruit consumption from 180 publications. To test which fruits were most frequently consumed across the Neotropical region and in each of its component countries these data were organized by bat species and country. In general, considering the 176 botanical genera eaten by these bats, the results showed a... |

| Eleven species of tanagers in Ibitipoca State Park, Minas Gerais, southeastern Brazil, were studied for 12 months and the birds diet was described. Fruits of 52 plant species were the main item consumed for all tanagers, representing 59.70% of all items in 1330 events, although different proportions in the use of this resource have been found among the bird species. The main plant families found were Myrtaceae with eight species accounting for 22.29% (n=177), and Melastomataceae with seven species accounting for 22.29% (n=177) of fruit intake. The most frequent plant species in the diet was Cecropia glaziovi Snethl. (Cecropiaceae), which made up 17.76% (n=141) of fruit intake of all species of tanagers. Arthropod consumption came second with 22.63%... |

| Fourteen bird species were observed visiting one specimen of Alchornea glandulosa Poepp., 1845, at the Horto Florestal Navarro de Andrade, Rio Claro, São Paulo State, Brazil. Among them, three species seem to be the most efficient seed dispersers of A. glandulosa at the study site: Myiodinastes maculatus (Müller, 1776), Empidonomus varius (Vieillot, 1818) e Tyrannus melancholicus Vieillot, 1819. Besides to swallow fruit whole, these birds contributed with 68.5% of the total feeding visits. A. glandulosa fruit are not the mainly part of the diet of any one of the observed bird species, since they do not fit in the frugivorous specialized category. However, as almost all the observed individuals swallow fruit whole, it is suppose that they promote an... |

| Thirty-five fruit species were sampled in seven municipalities located in the cerrado of the state of Mato Grosso do Sul (January 1993 to March 1997) in a study to evaluate the infestation by frugivorous flies. Species of six genera of Tephritoidea were reared from 29 host fruits: Anastrepha Schiner, Ceratitis MacLeay (Tephritidae); Dasiops Rondani, Lonchaea Fallén, Neosilba McAlpine, (Lonchaeidae) and Notogramma Loew (Otitidae). Fruit flies (Tephritidae) were found in 19 host fruits and were represented by 11 species: Anastrepha fraterculus (Wied.), A. grandis (Macquart), A. montei Lima, A. obliqua (Macquart), A. pickeli Lima, A. sororcula Zucchi, A. striata Schiner, A. turpiniae Stone, A. zenildae Zucchi, Anastrepha n. sp. and Ceratitis capitata (Wied.).... |

| Dehiscent fruits of Euphorbiaceae usually have two stages of seed dispersal, autochory followed by myrmecochory. Two stages of Margaritaria nobilis seed dispersal were described, the first stage autochoric followed by ornithocoric. Their dehiscent fruits are green and after they detached from the tree crown and fall on the ground, they open and expose blue metallic cocas. We studied the seed dispersal system of Margaritaria nobilis in a semi-deciduous forest in Brazil. In 80 h of focal observations, we recorded only 12 visits of frugivores, however the thrush Turdus leucomelas was the only frugivore that swallowed the fruits on the tree crown. Pitylus fuliginosus (Fringilidae) and Pionus maximiliani (Psittacidae) were mainly pulp eaters, dropping the seeds... |

| Embora os estudos de frugivoria e dispersão de sementes sejam importantes para a realização de planos de manejo e recuperação de ambientes degradados, pouco tem sido pesquisado sobre o assunto no cerrado brasileiro. Neste trabalho são apresentados aspectos da frugivoria e dispersão das sementes de Ocotea pulchella Mart. (Lauraceae) por aves. Treze espécies de aves foram registradas consumindo os frutos de O. pulchella em 72 horas de observação focal, entre os meses de agosto e outubro de 1999, numa área de cerrado da região central do estado de São Paulo (21º58' S, 47º52' W), Brasil. As principais espécies potencialmente dispersoras foram o sabiá-pardão, Turdus leucomelas (Muscicapidae), o sabiá-docampo, Mimus saturninus (Mimidae), o bem-te-vi, Pitangus... |

| 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 dispersal networks are not all alike and may be more complex than previously thought. Here, we used network theory to evaluate seed dispersal in a strongly impacted Atlantic Forest fragment in northeastern Brazil, where bats and birds are the only extant dispersers. We hypothesized that the seed dispersal network should be more modular then nested, and that the dispersers should segregate their services... |

| Fruit dispersal syndromes (groups of plants with similar fruit morphology, presumably adapted to dispersal by a particular set of vectors) have been described in a variety of tropical localities. In some cases the presence of different syndromes in each locality suggests independent evolution of fruit traits in response to selective pressures imposed by the particular animal community in each place. However, it is still unclear how general are fruit syndromes, and this is important to understand the evolution of mutualistic relationships. We compiled morphological information from about 500 fleshy fruited species at a lowland Neotropical forest in Tinigua National Park, Colombia, in an effort to test for the existence of fruit dispersal syndromes. We found... |

| In this paper, I discuss recent evidence concerning the adaptive significance of secondary metabolites in ripe fleshy fruits, and implications for seed dispersal by birds and other vertebrates. Specifically, I revisit a number of adaptive hypotheses originally presented and discussed by Cipollini & Levey in 1997, including the Attraction/Association, Seed Germination Effects, Attraction/Repulsion, Protein Assimilation, Gut Retention Time, Directed and General Toxicity, and Defense Tradeoffs hypotheses. I also present and discuss a new adaptive hypothesis, the Direct Nutritional Benefits hypothesis, posed to reflect recent discoveries concerning the positive dietary effects of some secondary metabolites. From this review, I conclude that focused... |

| Vertebrate frugivores have been suggested to reduce seed predation, indirectly controlling populations of insect seed predators (ISP) by means of consuming many individuals when feeding on fruits. The possibility has not been explored, however, that this 'frugivore predation' may differentially affect ISP according to species-specific differences in larval development time within the fruit. In the dry tropical forest trees Acacia pennatula and Guazuma ulmifolia we compared seed predation and the absolute and relative abundances of bruchid beetle species (Bruchinae) in two sites, one with large frugivores (cattle) and the other cattle-free for a considerable time. In the site with cattle we found a notable overall reduction in the proportion of seeds... |

| A study about the species of Piperaceae that are consumed by a colony of Carollia perspicillata (Linnaeus, 1758) in Parque Municipal Arthur Thomas (82,72 ha) was carried out. Five available species of Piperaceae were found in the park: Piper aduncum Linnaeus, Piper amalago (Jacq.) Yuncker, Piper crassinervium H.B.K., Piper gaudichaudianum Kunth and Piper sp. C. perspicillata fed on all of these species. During the spring, the most abundant item was P. amalago, but the consumption of P. aduncum was the highest. At the beginning of the summer, P. crassinervium was the most abundant and most consumed item. At the end of the summer and during the fall, P. gaudichaudianum was the most abundant and consumed item, even in May, when P. amalago was the most... |

| We record here the occurrence of seeds of several plant species in feces found inside the day roost of Chrotoperus auritus, at the Estação Experimental de Itirapina, State of São Paulo, Southeastern Brazil, in July 2001. The roost was used by only one adult female, non pregnant, during about a month. In the feces, fur of rodent (Muridae), bone fragments, fragments of Scarabaeidae and other beetles and insects, leaves (not determined) and many seeds of Piperaceae (Piper sp.), Urticaceae (Cecropia sp.) and Solanaceae (Solanum spp. and Cestrum sp.) were found. In the gut content, insect fragments, fur of rodent (Muridae) and plant remains were found. It was discussed why this carnivorous bat would be consuming plant items. |

| Trogons are pan-tropical forest birds that eat a mix of fruits and arthropods. With direct observations of wild feeding birds, I assessed the relative contribution of fruits and arthropods to the diet of three trogon species (Trogonviridis, T.surrucura, and T.rufus) at Parque Estadual Intervales, southeast Brazil. Fruits and arthropods made the bulk of the food items recorded, with a tendency of frugivory increasing with body mass. The Trogon species differed in the proportion of fruits and arthropods taken, with T.viridis being the most frugivorous species (66% of feeding bouts, n = 47). The relative contribution of fruits and arthropods did not differ between the wet and dry seasons for any species. In the omnivorous gradient, T.viridis is close to the... |

| Cerdocyon thous (Linnaeus, 1766) is the most widespread neotropical canid, most commonly inhabiting forested areas. This animal is a generalist omnivore that is able to use environments disturbed by human activities. The aim of this study was to describe its diet through the stomach content analysis of 30 samples obtained from specimens that were run over in a mosaic composed by Araucaria Pine Forest, Semidecidual Seasonal Forest, natural grasslands, and exotic vegetation. The items were quantified by frequency of occurrence (F.O.) and percentage of occurrence (P.O.). A total of 64 food items were found among 171 occurrences. According to F.O. method, plant items corresponded to 93.3% of the occurrences, followed by animal items (86.7%) and human rejects... |

| The diet of some leaf-nosed frugivorous bats - Artibeus Leach, 1821, Carollia perspicillata (Linnaeus, 1758) and Sturnira lilium (e. Geoffroy, 1810) - was studied for nine consecutive months through faecal analysis of individuais captured with mist-nets in a small forest remnant of Paraná state, Brazil. The analysis revealed that Artibeus spp. exhibited preference for fruits of Ficus spp. and Carollia perspicillata for those of Piper spp., which is in accordance with the results of previous studies. But contrary to what was expected, fruit of Solanum spp. were not found for the diet of Sturnira lilium in spite of their high availabilily (16 species) in the study area and their known relationship with this bat genus. The species of consumed fruit belonged... |
