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 aExpand

TOWARD AN INTEGRATION OF LANDSCAPE AND FOOD WEB ECOLOGY : The Dynamics of Spatially Subsidized Food Webs
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 inExpand

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 competitionExpand

The Evolution and Dynamics of Intraspecific Predation
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 itExpand

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 andExpand

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 biotaExpand

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 growingExpand

Why Are Parts of the World Green? Multiple Factors Control Productivity and the Distribution of Biomass
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 theirExpand
