Abstract Whether seed consumers affect plant establishment is an important unresolved question in plant population biology. Seed consumption is ubiquitous; at issue is whether seedling recruitment is limited by safe-sites or seeds. If most seeds inhabit sites unsuitable for germination, post-dispersal seed consumption primarily removes seeds that would otherwise never contribute to the population and granivory has minimal impacts on plant abundance. Alternatively, if most seeds ultimately… Expand
Seed dynamics of resprouting shrubs in grassy woodlands: Seed rain, predators and seed loss constrain recruitment potential
TLDR
This study suggests that seed predation is a key factor contributing to seed-limited recruitment in grassy woodland shrubs by reducing the number of seeds stored in the soil. Expand
Rodent‐limited establishment of bush lupine: field experiments on the cumulative effect of granivory
TLDR
Rodent exclusion substantially reduced seedling emergence and subsequent adult plant abundance of bush lupine, a large N-fixing shrub common to coastal dunes in California, and indicates that rodents play a critical role by limiting the abundance and biomass of a largeN-fixed shrub in dunes. Expand
Small-mammal seed predation limits the recruitment and abundance of two perennial grassland forbs.
TLDR
Evidence of seed limitation is found, with increasing density of seeds added leading to increased numbers of seedlings, and results suggest that granivores can have potentially important impacts in limiting forb abundance in grasslands communities. Expand
Rodent seed predation promotes differential recruitment among bird-dispersed trees in temperate secondary forests
TLDR
The selective early recruitment limitation exerted by predation may have a demographic effect in the long term, as judged by the positive relationship between early seedling emergence and the density of established recruits. Expand
Seed predators limit plant recruitment in Neotropical savannas
TLDR
The results lend support to the recent hypothesis that herbivores have major and underappreciated impacts in Neotropical savannas, and that top–down factors can influence the demography of plants in this extensive and biodiversity-rich biome in previously unexplored ways. Expand
The demographic role of soil seed banks. II. Investigations of the fate of experimental seeds of the desert mustard Lesquerella fendleri
TLDR
It is suggested that the demography of desert surface plant populations may depend more on the time between seed inputs and the longevity of these seeds in the soil than on the amount of seeds produced at any one point in time and space. Expand
Habitat-specific impacts of multiple consumers on plant population dynamics.
TLDR
The results illustrate how density dependence, habitat-specific seed dynamics, and particular demographic impacts of consumers interact to shape plant population responses to consumers. Expand
Past and present disturbances generate spatial variation in seed predation
Seed survival is a key process for plant populations; variation in the activity and abundance of animals that consume seeds can lead to dramatic shifts in seed fate. Because granivores may respond toExpand
Pre-dispersal seed predation and seed limitation in an annual legume
TLDR
V. angustifolia is assumed to be a weak competitor and, in spite of the low percentage of seed loss to pre-DSPs, it is most likely limited by seed number, the deficit in using available microsites might be caused by post-dispersal mortality factors. Expand
Consumers Limit the Abundance and Dynamics of a Perennial Shrub with a Seed Bank
TLDR
This study suggests that plant population dynamics and distribution may be more strongly influenced by consumers of seeds and seedlings than is currently recognized. Expand

Post-dispersal seed predation in grassland: its magnitude and sources of variation.
TLDR
Post-dispersal seed predation by rodents and invertebrates, was studied in two grassland sites in Berkshire, UK and found density-dependence varied with seed size, with predation of large seeds less influenced by a reduction in seed density. Expand
Effects of Dispersers, Gaps, and Predators on Dormancy and Seedling Emergence in a Tropical Herb
TLDR
Seedling emergence in this ant—dispersed herb with a relatively long—lived seed bank depends upon a complex of factors, suggesting an interaction of the effects of biotic dispersal to local safe microsites with larger scale effects of spatial and temporal variation in the abiotic environment.

Seed and early seedling predation in the forest understory and in treefall gaps
TLDR
Although the high light environment of a gap enhances seedling growth, the extreme predation on seeds and young seedlings may make successful establishment in a treefall gap an extremely unlikely event. Expand
Control of seedling emergence by ground cover and seed predation in relation to seed size for some old-field species
TLDR
A field experiment was conducted to test whether control of seedling emergence by ground cover and seed predation depended on seed size, and the relationship between seed mass and effects ofGround cover and (or) seedpredation on seedling emerged was determined. Expand

INSECT HERBIVORES AND PLANT POPULATION DYNAMICS
TLDR
This review concentrates on material published from 1 984 to 1987 and examines two of the best sources of evidence on the impact of insect feeding on plant population dynamics: the release of specialist insect herbivores against target weed species in classical. Expand
Effects of litter, distance, density and vegetation patch type on postdispersal tree seed predation in old fields
TLDR
Very few Juniperus virginiana seeds were lost to predation but predation for all other test species was reduced by additions of Quercus litter and solidago litter, and seed predation was also reduced by increasing distance from the forest edge. Expand
Experimental evidence for insect impact on populations of short-lived, perennial plants, and its application in restoration ecology
TLDR
The results under these experimental conditions show that overall germination rates were low, and that postdispersal seed predation had a small, but signifi- cant, effect on seedling recruitment in the open habitat associated with blowouts. Expand

Effect of Inflorescence‐Feeding Insects on the Demography and Lifetime of a Native Plant
TLDR
It is concluded that the inflorescence-feeding insect herbivores limited seed production, seedling recruitment, plant density, and maternal fitness of this plant under natural conditions, which challenges current theoretical models of the effect of insects on plant population dynamics. Expand
