Seed Dispersal by Primates and Implications for the Conservation of a Biodiversity Hotspot, the Atlantic Forest of South America
(2016-06-01)
Primates play a fundamental role as seed dispersers, particularly in tropical rainforests. Because defaunation and fragmentation are leading several primate species to local extinction, it is fundamental to understand the ...
A new rain-operated seed dispersal mechanism in Bertolonia mosenii (Melastomataceae), a Neotropical rainforest herb
(2002-03-19)
Although widespread among fungi, lichens, liverworts, and mosses, seed dispersal mechanisms operated by rain are unusual among flowering plants. Generally speaking, two mechanisms are involved in seed dispersal by rains: ...

Are tortoises important seed dispersers in Amazonian forests?
(SPRINGER, 2009)
According to most studies on seed dispersal in tropical forests, mammals and birds are considered the main dispersal agents and the role played by other animal groups remains poorly explored. We investigate qualitative and ...
Seed deposition patterns and the survival of seeds and seedlings of the palm Euterpe edulis
(Elsevier B.V., 2001-07-01)
The seed deposition pattern created by a seed disperser is one of the components of the efficiency of a species as seed disperser, and ultimately may influence the recruitment of a plant species. In this study, we used the ...
Seed dispersal and predation in the endemic Atlantic rainforest palm Astrocaryum aculeatissimum across a gradient of seed disperser abundance
(Springer Tokyo, 2009-11-01)
Tropical forests have been subject to intense hunting of medium and large frugivores that are important in dispersing large-seeded species. It has been hypothesized that in areas with extinction or low abundance of medium ...

The fate of Attalea phalerata (Palmae) seeds dispersed to a tapir latrine
(2001)
At the Beni Biological Station, Bolivia, we compared the fate of seeds of the palm Attalea phalerata dispersed by tapirs to a lattine with that of non-dispetsed seeds. Survival of seeds that had passed through tapir guts ...
Frugivory and seed dispersal by tapirs: an insight on their ecological role
(Wiley-Blackwell, 2013-03-01)
Tapirs are one of the last extant megafauna species that survived the Pleistocene extinctions. Given their size and digestive system characteristics, tapirs might be the last potential seed disperser of plant species that ...
Quinolizidine alkaloids in Ormosia arborea seeds inhibit predation but not hoarding by agoutis (Dasyprocta leporina)
(Kluwer Academic/plenum Publ, 2003-05-01)
Quinolizidine alkaloids (QAs) are secondary compounds found in seeds of many species of plants, possibly protecting them against pathogens and seed predators. QAs were isolated from Ormosia arborea seeds and bioassayed ...
