P ublished online October 2013 .

Article. Subjects: Applied Ecology (Environmental Science); Ecology and Conservation; Plant Ecology; Zoology and Animal Sciences. 8922 words.

Competition is one of the most ubiquitous of species interactions. It occurs any time a resource that is essential to growth and reproduction (e.g., food, shelter, nesting sites) occurs in...

Indirect Effects in Communities and Ecosystems

in Ecology

P ublished online May 2012 .

Article. Subjects: Applied Ecology (Environmental Science); Ecology and Conservation; Plant Ecology; Zoology and Animal Sciences. 6826 words.
