The purpose is to document the ubiquity and importance of intraguild predation and to establish a theoretical framework for its analysis, which is the first synthesis of IGP into a general work.
We focus on the implications of movement, landscape variables, and spatial heterogeneity for food web dynamics. Movements of nutrients, detritus, prey, and consumers among habitats are ubiquitous in…
One of the purposes is to establish a theoretical framework for the organization and interpretation of the numerous observations of intraspecific predation.
The consequences of incorporating IGP into standard models of exploitative competition and food chains (a general resource-consumer model, a Lotka-Volterra food chain model, and Schoener's exploitative Competition model) are explored and a general criterion for coexistence in IGP systems is suggested.
It is argued that most cataloged webs are oversimplified caricatures of actual communities, and patterns from food webs of real communities generally do not support predictions arising from dynamic and graphic models of food-web structure.
An up-to-date synthesis of all that is known about scorpions is presented, covering anatomy and morphology, systematics, biogeography, and palaeontology.
It is proposed that such flow is often a key feature of the energetics, structure, and dynamics of populations, food webs, and communities whenever any two habitats, differing in productivity, are juxtaposed.
It is suggested that nutrient enrichment via guano ramifies to affect the entire food web on hyperarid, naturally nutrient poor islands in the Gulf of California, where nutrient input via seabird guano directly increases N and P concentrations up to 6-fold in soils; these nutrients enrich plants.
