Small-mammal seed predation limits the recruitment and abundance of two perennial grassland forbs.
Although post-dispersal seed predators are common and often reduce seed density, their influence on plant population abundance remains unclear. On the one hand, increasing evidence suggests that many plant populations are seed limited, implying that seed predators could reduce plant abundance. On the other hand,.it is generally uncertain whether the magnitude of seed limitation imposed by grani...
متن کاملUncoupling the Effects of Seed Predation and Seed Dispersal by Granivorous Ants on Plant Population Dynamics
Secondary seed dispersal is an important plant-animal interaction, which is central to understanding plant population and community dynamics. Very little information is still available on the effects of dispersal on plant demography and, particularly, for ant-seed dispersal interactions. As many other interactions, seed dispersal by animals involves costs (seed predation) and benefits (seed dis...
متن کاملSeed size and provenance mediate the joint effects of disturbance and seed predation on community assembly
1. Local plant community assembly is influenced by a series of filters that affect the recruitment and establishment of species. These filters include regional factors that limit seeds of any given species from reaching a local site as well as local interactions such as post-dispersal seed predation and disturbance, which dictate what species actually establish. How these filters interact to in...
متن کاملGlobal patterns in seed size
Aim To provide the first global quantification of the slope and shape of the latitudinal gradient in seed mass, and to determine whether global patterns in seed mass are best explained by growth form, vegetation type, seed dispersal syndrome, or net primary productivity (NPP).
متن کاملPost-dispersal seed predation in relation to selection on seed size in Dithyrea californica
Question: We asked whether a desert ant population and a community of heteromyid rodents select Dithyrea californica seeds in relation to their size, frequency of seed sizes, and absolute density and thus have the capacity to influence natural selection on seed size. Hypothesis: Following the predictions of optimal diet theory, we hypothesized that seed predators will prefer to prey upon larger...
