“…These traits, together with a wide home-range of hundreds or several thousand hectares and the capability of straight-line displacements 4 20 km (Fragoso et al 2003, Noss et al 2003, promote long-distance dispersal of viable seeds. In addition, tapirs often use latrines generating seed clumps (Fragoso 1997, Olmos et al 1999, Quiroga-Castro & Roldán 2001. This defecation pattern has been well described for the Brazilian Amazon Forest, where most latrines contained large amounts of seeds and juveniles of Attalea maripa (Fragoso 1997, Fragoso & Huffman 2000, Fragoso et al 2003.…”

Seed Dispersal of the Palm Syagrus romanzoffiana by Tapirs in the Semi‐deciduous Atlantic Forest of Argentina

Vertebrates play a fundamental role in the dispersal of Neotropical trees, generating different seed shadows according to their physical and behavioral features. Tapirs are capable of consuming great quantities of large fruits, and they defecate seeds far from parent trees. For instance, intact seeds of the palm Syagrus romanzoffiana have been found in tapir dung piles in the Atlantic Forest of southeastern Brazil, suggesting that tapirs effectively disperse this species. However, recruitment was not examined therein. We studied tapir endozoochory of large and medium seeds in the semi-deciduous Atlantic Forest of Argentina by examining dung piles found within Iguazu National Park. We recorded dung-pile positions to evaluate the spatial distribution. We also counted the number of juveniles in 2 Â 2 m quadrats placed on old dung piles in latrines, beneath adults and in random sites to estimate recruitment levels. Syagrus romanzoffiana seeds were present in 98 percent of dung piles, averaging 4 200 seeds/dung pile, indicating that this species constitutes the main fruit component in the tapir's diet. Dung piles showed a clumped deposition pattern reflecting the use of latrines. Juvenile recruitment in latrines was 21 times higher than that of under-adult sites and 500 times greater than in random sites, and correlated with the frequency of use of the areas. We concluded that the lowland tapir is a major disperser of S. romanzoffiana. Given that this palm can be considered a keystone species, a disruption of this interaction might affect the entire community of frugivores in the long term.Abstract in Spanish is available at http://www.blackwell-synergy.com/loi/btp.

-Ants can nest in a wide variety of substracts. This paper shows Syagrus romanzoffi ana seed utilization by ants in an Atlantic secondary forest. We report 29 seeds occupied by small-bodied ants, with 27 of them showing at least two ant development stages. Although a large number of seeds were sampled, a low level of ant occupation was observed.KEY WORDS: Palm, nest place, Hymenoptera RESUMO -As formigas podem nidifi car em uma ampla variedade de substratos. Este estudo relata o uso das sementes de Syagrus romanzoffi ana em fl oresta atlântica secundária, como local para nidifi cação de formigas. Foram encontradas 29 sementes ocupadas por formigas de pequeno porte, sendo que 27 delas apresentaram pelo menos dois estágios de desenvolvimento de formigas. A taxa de ocupação foi baixa apesar de as sementes serem abundantes.
