Abstract:
Most seed-predation studies have evaluated pre- or post-dispersal predation separately, in one or a few species. Assessments of the overall importance of pre- v. post-dispersal seed predation at the community level are generally lacking. Here, we quantify levels of pre and post-dispersal seed predation in >25 plant species in a mediterranean-type climate montane forest in central Chile in two periods of study (1995–1996 and 1997–1998). Almost all species analysed suffered at least some seed losses to pre-dispersal and/or post-dispersal seed predation. However, among species, magnitudes of b

Abstract:
Abstract:Parrots represent a large biomass of canopy granivores in tropical forests, and may be effective pre-dispersal seed predators. We evaluated the importance of the lilac-crowned parrot (Amazona finschi) as a pre-dispersal seed predator of Astronium graveolens (Anacardiaceae) in tropical dry forest. Seeds were collected in fruit-traps beneath 22 trees to compare pre-dispersal seed predation by parrots and insects, and determine whether intensity of seed predation was related to fruit-crop size or the aggregation of fruiting conspecifics around focal trees. Ground-level exclosures were es

Abstract:
AbstractThis study examines whether post-dispersal seed predators could be an important selective force in determining the seed bank strategies of grassland plants. It tests the hypothesis that species with persistent seed banks should sustain proportionally less predation of buried seeds than species which have transient seed banks and that this should be true irrespective of seed size. Results are drawn from a field experiment examining the relative susceptibility of surface versus buried seeds for 19 herbaceous taxa exhibiting different degrees of seed bank persistence. The data were consis

Abstract:
This study examined post-dispersal seed predation and soil seed reserves in four remnant populations of E. salmonophloia in the central wheatbelt of Western Australia to determine the effect of these factors on recruitment. Diurnal observations of post-dispersal seed predation at regular intervals of 2 months were undertaken over a 12 month period using artificial baits. Four species of ants were seen removing seeds from artificial baits regularly. Surveys of soil seed reserves revealed that E. salmonophloia does not form a soil seed bank despite a continual seed rain from canopy seed reserves

Abstract:
We investigated the seed dispersal of Aglaia spectabilis, a large-seeded tree species in a moist evergreen forest of Khao Yai National Park in Thailand. Although one-to-one relationships between frugivores and plants are very unlikely, large-seeded plants having to rely on few large frugivores and therefore on limited disperser assemblages, might be vulnerable to extinction. We assessed both the frugivore assemblages foraging on arillate seeds of Aglaia spectabilis and dispersing them and the seed predator assemblages, thereby covering dispersal as well as the post-dispersal aspects such as se

Abstract:
This paper evaluates the post-dispersal artificial seed predation rates in two areas of the southeastern Amazon forest-savanna boundary, central Brazil. We conducted the survey in a disturbance regime controlled research site to verify if exists an edge effect in these rates and if the disturbance (in this case annual fire and no fire) affects seed predation. We placed 800 peanuts seeds in each area at regular distance intervals from the fragment`s edge. Data were analyzed by a likelihood ratio model selection in generalized linear models (GLM).

Abstract:
Aspects of the seed ecology of Hypericum gramineum Forster, a perennial forb that is native to Australia, were examined in several germination and seed predation experiments. Fresh seeds were innately dormant. Highest germination of non-dormant seeds occurred in the light at a temperature regime of approximately 35/25˚C. The results of field experiments indicated that there was no strongly seasonal effect on germination. Predators, such as ants, removed < 20% seeds, thereby suggesting that post-dispersal seed predation is relatively unimportant in the dynamics of H. gramineum populations. S

Abstract:
Invasions by exotic plants may be more likely if exotics have low rates of attack by natural enemies, including post-dispersal seed predators (granivores). We investigated this idea with a field experiment conducted near Newmarket, Ontario, in which we experimentally excluded vertebrate and terrestrial insect seed predators from seeds of 43 native and exotic old-field plants. Protection from vertebrates significantly increased recovery of seeds; vertebrate exclusion produced higher recovery than controls for 30 of the experimental species, increasing overall seed recovery from 38.2 to 45.6%.

Abstract:
Despite extensive international acceptance of the critical role of mammalian post-dispersal seed predation in many plant communities, in New Zealand we have limited knowledge of these predators’ influence on plant recruitment in our forests. The principle objective of my thesis was to determine the importance of exotic mammals as post-dispersal seed predators in a New Zealand conifer-broadleaf forest remnant. To address this goal, I used a series of field-based experiments where the actions of different post-dispersal seed predators were separated by wire-mesh exclosures. My study was conduct
