The influence of seed structure and strength on their destruction by granivores is central to understanding the dynamics of granivore-plant interactions. For up to nine seed species, the effects of seed size (cm3), mass (mg), density (mg/cm3) and coat strength (MPa) on the damage inflicted by three post-dispersal granivores (Harpalus pensylvanicus, Anisodactylus sanctaecrucis, and Gryllus pennsylvanicus) were evaluated. Seed destruction rates by G. pennsylvanicus were statistically unrelated to… 

Do properties and species of weed seeds affect their consumption by carabid beetles?

That carabids preferred water-imbibed and damaged seeds may suggest an involvement of olfactory clues in the seed selection process, and/or shorter seed-handling times.

Which Seed Properties Determine the Preferences of Carabid Beetle Seed Predators?

The result suggests that the seed traits that carabids respond to may be specific to taxonomic and likely relate to the degree of specialisation for seeds.

Burial-induced changes in the seed preferences of carabid beetles (Coleoptera: Carabidae)

This study provides the first conclusive evidence that invertebrate seed predators will feed on seeds from seed banks, although they prefer fresh seeds.

Persistence and Changes in Morphological Traits of Herbaceous Seeds Due to Burial in Soil

It is found that in most species, seed mass, volume and proportion of persistent seeds declined with YAB, while other morphological traits were less variable, and the decline in these traits with Y AB was best fitted with logistic regression.

Arthropod Granivory of Lime-Coated Cover Crop Seeds

Protection of cover crop seeds from granivory through a calcium carbonate coating may allow producers to adjust seeding rates and save on costs, increasing the rate of adoption for this conservation practice.

The role of invertebrates in seedling establishment in a heterocarpic plant, Atriplex sagittata

Invertebrate predation is important factor of seed and seedling mortality of A. sagittata and seed heteromorphism modifies its intensity and timing, and their consumption by invertebrates (carabids, isopods and slugs) was studied.

Ground beetles (Coleoptera: Carabidae) as predators of conifer seeds

The consumption of seeds of six coniferous species by four common carabid species is determined and postdispersal predation of seeds by carabids may be an important mortality factor in some conifer species.

Weed seed choice by carabid beetles (Coleoptera: Carabidae): Linking field measurements with laboratory diet assessments

Carabid beetles could potentially provide a number of ecosystem services in arable fields, including the regulation of weeds by eating seeds. Spatio-temporal variability in the incidence of predation

Molecular approach to describing a seed-based food web: the post-dispersal granivore community of an invasive plant

A more diverse granivore community had trophic linkages to seeds than has been previously realized under field conditions and is clearly important as a form of biotic resistance to invasive and weedy plants.

Depth of Seed Burial and Gender Influence Weed Seed Predation by Three Species of Ground Beetle (Coleoptera: Carabidae)

Investigation of how seed burial affects consumption of weed seeds (volunteer canola) by adult ground beetles found higher seed consumption by females of all species, and greater consumption of seeds scattered on the soil surface compared with seeds buried at any depth.



Seed Selection by the Red Imported Fire Ant (Hymenoptera: Formicidae) in the Laboratory

Repellent and attractant surface chemical swas demonstrated for some seeds, and chemicals could be extracted from seeds that could be considered attractive, some seeds appeared to be protected from S. invicta predation by repellents.

Ground beetles (Carabidae) as seed predators

Seed predation thus may be an effective component of weed control on arable land, particularly at low weed densities, and may selectively influence the quantity of seed of particular herb species that enters the soil seed bank.

Seed selection in the Java Sparrow (Padda oryzivora): preference and mechanical constraint

In two series of experiments, Java Sparrows (Padda oryzivora) were offered safflower seeds and showed selection as a result of mechanical constraints and selection asA result of preference, aiming to discriminate between these two effects.

Harvester Ant Foraging and Shrub‐Steppe Seeds: Interactions of Seed Resources and Seed Use

Seeds preferences by the western harvester ant, Pogonomyrmex occidentalis, related to seed availability and, in turn, affected the soil seed pool, and preference by ants was correlated with the seasonal availability of preferred species, but not with unpreferred seeds.


It is concluded that the majority of species adapted for ant dispersal produce relatively strong seeds, and this may explain the low level of predation recorded for these species.

Harvester Ants (Pogonomyrmex spp.): Their Community and Ecosystem Influences

Because of nest densities, the longevity of nests, and the amount of seed harvested and soil handled, harvester ants have significant direct and indirect effects on community structure and ecosystem functioning.

Multalism between Harvester Ants and a Desert Ephemeral: Seed Escape from Rodents

Manipulation of thedensity of D. discolor seed in these tests suggests that seed utilization by rodents is distance-responsive to the parent canopy rather than dependent on the density of seeds.

Post‐dispersal seed predation of non‐target weeds in arable crops

The potential relevance of post-dispersal seed predation to the development of weed management systems that maximize biological control through conservation and optimize herbicide use, is discussed.

Size and lipid content of nonmyrmecochorous diaspores: effects on the interaction with litter-foraging ants in the Atlantic rain forest of Brazil

The size and the lipid-content of the diaspores were shown to be major determinants of the outcome of ant-diaspore interactions in the post-dispersal fates of nonmyrmecochorous seeds in tropical forests.
