The crab-eating fox (Cerdocyon thous) exhibits a very generalist habit and fruits compose a large proportion of its diet. However, few studies evaluated the importance of this animal as seed disperser. In the Restinga forest, in the Atlantic forest of Brazil, C. thous consumes fruits of Eugenia umbelliflora, a Myrtaceae species, which is dispersed chiefly by birds. This study evaluated the effects of gut transit on seed germination, and size selection of E. umbelliflora fruits by the crab-eating fox. We did not find differences on germination rates between seeds dispersed by foxes and control ones, but seeds dispersed by foxes germinated faster, which may be important for plant recruitment. Seeds consumed by C. thous were smaller than those available on... |

Bats of the genus Artibeus are among the most important seed dispersers in early successional forests. We report observations on the foraging behavior of Artibeus lituratus in Pedra da Cebola Municipal Park, an urban park in the city of Vitória, Espírito Santo, southeastern Brazil. Observations were made during six consecutive days (April 1st to April 6th, 2006). Three mist-nets were opened each night close to a Maclura tinctoria tree (Moraceae), remaining open from 18:00 to 22:00, totaling four hours per night, and 24 hours of sampling effort. We observed two peaks of feeding activity at the tree, one between 18:20 and 19:30, and a second one at 21:00. This is the first observation of Artibeus lituratus feeding on M. tinctoria fruits, therefore adding a... |

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... |

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%... |

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... |

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... |
