TLDR
The spider in the ecological play is a central character in the story of how spiders avoid competition and the impact of spiders on insect populations and competitionist views of spider communities are examined.Abstract:

Are there general laws in ecology
TL;DR: It is argued that ecology has numerous laws in this sense of the word, in the form of widespread, repeatable patterns in nature, but hardly any laws that are universally true.

The Ecological Consequences of Shared Natural Enemies
and R D Holt,John H. Lawton +1 more
TL;DR: Apparent competition arises between focal and alternative prey populations because, in the long term, enemy abundance depends on total prey availability; by increasing enemy numbers, alternative prey intensify predation on focal prey.
Journal ArticleDOI
Spiders (Araneae) useful for pest limitation and bioindication
TL;DR: It is argued that fluctuations in the spider community structure allows the bioevaluation of human disturbances because of the close correspondence between the vegetation architecture and the composition of the associated spider community.
Journal ArticleDOI
Higher-order predators and the regulation of insect herbivore populations
TL;DR: The hypothesis that higher-order predators may constrain the top-down control of herbivore populations is evaluated and manipulative field experiments will be especially valuable in furthering the understanding of their roles in arthropod communities.
Journal ArticleDOI
Influence of intraguild predation among generalist insect predators on the suppression of an herbivore population.
TL;DR: It is concluded that intraguild predation in this system is wide-spread and has potentially important influences on the population dynamics of a key herbivore.
