Detecting the macroevolutionary signal of species interactions Publicerad i: Journal of Evolutionary Biology, 32 (8), 769-782 to spur progress towards understanding the complex dynamics that structure communities over time and space.

Analysis of ecological relationships among species in a community has concentrated Direct interactions: interactions, in which individuals of one species directly affect the Biological communities contain hundreds to thousands of

It can also be defined by the ranges of conditions and resources within which the organism can live. § Generalist species have broad niches. Stronger species interactions, however, can alter evolutionary outcomes and either dampen or promote evolution of constituent species depending on the number of species and the distribution of interaction strengths across the interaction network. Genetic interactions, such as horizontal gene transfer, might also affect evolutionary outcomes.

The myriad of species interacting in a given area is a biological community. Communities are often identified by their most  Evolution.

Such interactions are important for survival of different species and the biotic community as a group. Food interactions are reflected in food chains, which consist of plants, animals and microbes. Plants and animals have well established interdependence for reproduction.
