Partitioning the relative contribution of one-phase and two-phase seed dispersal when evaluating seed dispersal effectiveness
(Wiley-Blackwell, 2015-02-01)
Seed dispersal effectiveness (SDE) is a conceptual framework that aims at quantifying the contribution of seed dispersal vectors to plant fitness. While it is well recognized that diplochorous dispersal systems, characterized ...
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 ...
Persistence of the effect of frugivore identity on post-dispersal seed fate: consequences for the assessment of functional redundancy
(2017-05-01)
Large frugivores play an important role as seed dispersers and their extinction may affect plant regeneration. The consequences of such extinctions depend on the likelihood of other species being functionally redundant and ...
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: ...
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 ...
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 ...
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 ...
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 ...
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 ...
Dormancy as exaptation to protect mimetic seeds against deterioration before dispersal
(OXFORD UNIV PRESS, 2010)
Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant ...
