THE ECOLOGY AND EVOLUTION OF INTRAGUILD PREDATION: Potential Competitors That Eat Each Other
Interactions between species are usually categorized as either competition (-), predation/parasitism (+ -), mutualism (+ +), commensalism (+ 0), or amensalism (-0). Intraguild predation (IGP) is a… Expand
TOWARD AN INTEGRATION OF LANDSCAPE AND FOOD WEB ECOLOGY : The Dynamics of Spatially Subsidized Food Webs
- G. Polis, J. B. Anderson, R. Holt
- 2005
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… Expand
A Theoretical Framework for Intraguild Predation
Many important issues in community ecology revolve around the interplay of competition and predation. Species that compete may also be locked in predator-prey interactions, a mixture of competition… Expand
The Evolution and Dynamics of Intraspecific Predation
- G. Polis
- Biology
- 1 November 1981
Intraspecific predation, the process of both killing and eating an individual of the same species, is a significant and widespread process that until recently has not received the attention it… Expand
Food Web Complexity and Community Dynamics
Food webs in nature have multiple, reticulate connections between a diversity of consumers and resources. Such complexity affects web dynamics: it first spreads the direct effects of consumption and… Expand
Complex Trophic Interactions in Deserts: An Empirical Critique of Food-Web Theory
- G. Polis
- Biology
- The American Naturalist
- 1 July 1991
Food webs in the real world are much more complex than food-web literature would have us believe. This is illustrated by the web of the sand community in the Coachella Valley desert. The biota… Expand
The Biology of Scorpions
- G. Polis
- Biology
- 1 May 1990
An up-to-date synthesis of all that is known about scorpions. The introduction and 11 papers cover anatomy and morphology; systematics, biogeography, and palaeontology; life history; behavioural… Expand
Linking Marine and Terrestrial Food Webs: Allochthonous Input from the Ocean Supports High Secondary Productivity on Small Islands and Coastal Land Communities
This study quantifies the flow of energy and biomass from a productive marine system to a relatively unproductive terrestrial system. Biomass from marine food webs (here, the Gulf of California)… Expand
Intraguild predation: The dynamics of complex trophic interactions.
There is a long-standing debate in ecology concerning the relative importance of competition and predation in determining community structure. Recently, a novel twist has been added with the growing… Expand
Why Are Parts of the World Green? Multiple Factors Control Productivity and the Distribution of Biomass
- G. Polis
- Biology
- 1 July 1999
This paper evaluates the multiple factors that determine the production of plant biomass and its distribution among producers and various trophic groups of con_ ?^)^ Osumers. In rough order of their… Expand
