Terrestrial Trophic Cascades: How Much Do They Trickle?
Although more consensus is now emerging on the magnitude and frequency of cascading trophic effects in aquatic communities, the debate over their terrestrial counterparts continues. We used… Expand

Cannibalism among generalist predators has implications for the dynamics of terrestrial food webs. Spiders are common, ubiquitous arthropod generalist predators in most natural and managed… Expand

IMPACT OF A DETRITAL SUBSIDY ON TROPHIC CASCADES IN A TERRESTRIAL GRAZING FOOD WEB
Theory predicts that allochthonous energy subsidies can modify the strength of trophic cascades in food webs. We tested the hypothesis that a detrital subsidy would enhance trophic cascades in the… Expand
Growth, development, and survival of a generalist predator fed single- and mixed-species diets of different quality
Abstract It is often assumed that prey species consumed by generalist predators are largely, though not entirely, equivalent in terms of their value to the predators. In contrast to this expectation,… Expand
Cannibalism Regulates Densities of Young Wolf Spiders: Evidence From Field and Laboratory Experiments
We conducted field and laboratory experiments to examine the relative con- tributions of mortality from natural enemies and cannibalism to population regulation of the wolf spider Schizocosa ocreata.… Expand
Behavioral and ecophysiological responses of a generalist predator to single- and mixed-species diets of different quality
Abstract Prey of different quality can be distinguished by their effects on fitness parameters (e.g., survival, growth, development) of the predator. This paper describes a series of experiments with… Expand
Wandering spiders limit densities of a major microbi-detritivore in the forest-floor food web

- 31 March 2004
Abstract In a long-term field experiment, densities of wandering spiders (i.e. species that do not build webs to capture prey) were reduced in order to determine whether or not a major group of… Expand
BOTTOM-UP LIMITATION OF PREDACEOUS ARTHROPODS IN A DETRITUS-BASED TERRESTRIAL FOOD WEB
Knowing how an increase in the resource base of a food web produces effects that propagate through the web is central to developing a clearer understanding of food- web structure and dynamics. In a… Expand
