The functional response of a hoarding seed predator to mast seeding.
Mast seeding involves the episodic and synchronous production of large seed crops by perennial plants. The predator satiation hypothesis proposes that mast seeding maximizes seed escape because seed predators consume a decreasing proportion of available seeds with increasing seed production. However, the seed escape benefits of masting depend not only on whether predators are satiated at high l...
متن کاملINSECT FAUNA OF CONIFEROUS SEED CONES: Diversity, Host Plant Interactions, and Management
Tree reproductive structures-pollen and seed cones, or microand mega sporangia-represent an extremely rich source of food for many animals (166). Although some species exploit pollen cones (189), in this review we deal exclusively with those exploiting seed cones prior to seed dispersal. Insects are considered the most important seed predators during the predispersal phase of seed development ...

متن کاملOn the origins of extreme mycorrhizal specificity in the Monotropoideae (Ericaceae): performance trade-offs during seed germination and seedling development.
Fungal-induced seed germination is a phenomenon characteristic of mycorrhizal plants that produce dust-like seeds with only minimal nutritional reserves. In such systems, fungi trigger germination and/or subsidize development. We studied mycorrhizal germination in relation to mycorrhizal specificity in the Monotropoideae, a lineage of dust-seeded non-photosynthetic plants that are dependent upo...
متن کاملPredispersal reproductive ecology of an arid land crucifer, Moricandia moricandioides: effect of mammal herbivory on seed production
In this paper the effect of herbivory on the seed production of Moricandia moricandioides (Cruciferae), an annual species living in arid habitats of southeastern Spain, is analysed. Firstly, the flowering and fruiting phenology and the composition and structure of the pollinator guild is described, in order to compare the overall effect of mutualistic species vs. that of antagonistic species on...
