Document Summary
Indirect effects come in a greater variety of designs than direct interactions. Indirect interactions pose a far greater challenge to understanding and predicting effects of a species on other species than direct, 2-species interactions. Indirect interactions increase in number and relative importance to a community as species diversity increases; thus they contribute to turning a species assemblage into a complex, interactive system. The first colonizers may only have to deal with the environment. But as a habitat is filled exploitation, competition, mutualism, predation all become common. Indirect effects describe how consequences of pair wise direct interactions between species are transmitted to other species either through behavioural modifications, altered spatial distributions, or altered abundances in the food web. Change in colour, size, defensive chemistry - trait. Indirect effects are a logical consequence of the fact that species are interacting mediated effects with larger interconnected food webs. There is varying different types and intensities of indirect effects.
