Gaps critical for the survival of exposed seeds during Cerrado fires
(2018-01-01)
The fine-scale effects of fire and the consequences for seed survival are poorly understood, especially in the Cerrado (Brazilian savannas). Thus, we investigated whether vegetation gaps (bare soil patches) influence the ...
Seed germination traits can contribute better to plant community ecology
(2016-05-01)
Analyses of functional traits have become fundamental tools for understanding patterns and processes in plant community ecology. In this context, regenerative seed traits play an important, yet overlooked, role because ...
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 ...
THE EXTENT of SEED PREDATION BY BRUCHINE BEETLES (COLEOPTERA: CHRYSOMELIDAE: BRUCHINAE) IN A HETEROGENEOUS LANDSCAPE IN SOUTHEASTERN BRAZIL
(Coleopterists Soc, 2012-09-01)
In this study, seed predation rates imposed by bruchines and the composition of bruchine species and their host plants were assessed in a heterogeneous landscape in southeastern Brazil. Fruits were collected from 49 plants ...

Storage in cerrado soil and germination of Psychotria vellosiana (Rubiaceae) seeds
(2006-08-15)
The regeneration of plant communities from seed depends, to a large extent, on the capacity of the seed remaining viable in the soil. The viability and germination of artificially buried Psychotria vellosiana seeds in ...

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 ...
