The ecological consequences of shared natural enemies
When multiple victim species (eg prey, host) are attacked by one or more shared enemy
species (eg predator, pathogen), the potential exists for apparent competition between victim …

Omnivory in terrestrial arthropods: mixing plant and prey diets
M Coll, M Guershon - Annual review of entomology, 2002 - annualreviews.org
▪ Abstract Many terrestrial communities include omnivorous arthropods that feed on both
prey and plant resources. In this review we first discuss some unique morphological …

Food web complexity and community dynamics
GA Polis, DR Strong - The American Naturalist, 1996 - journals.uchicago.edu
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 …

Weak trophic interactions and the balance of nature
K McCann, A Hastings, GR Huxel - Nature, 1998 - nature.com
Ecological models show that complexity usually destabilizes food webs,, predicting that food
webs should not amass the large numbers of interacting species that are in fact found in …

A theoretical framework for intraguild predation
RD Holt, GA Polis - The American Naturalist, 1997 - journals.uchicago.edu
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 …

Linking marine and terrestrial food webs: allochthonous input from the ocean supports high secondary productivity on small islands and coastal land communities
GA Polis, SD Hurd - The American Naturalist, 1996 - journals.uchicago.edu
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 …

A cross‐ecosystem comparison of the strength of trophic cascades
Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a
wide variety of food webs, the magnitudes of their effects are often quite variable. We …

Modelling food chain structure and contaminant bioaccumulation using stable nitrogen isotopes
G Cabana, JB Rasmussen - Nature, 1994 - nature.com
THE nitrogen pools of animals are enriched in 15N relative to their food1, with the top
predators having the highest concentrations of this stable isotope2. The use of δ15N to …
