A commonly used example of mutualism in mosaic coevolution is that of the plant and pollinator.Anderson and Johnson studied the relationship between the length of the proboscis of the long-tongued fly (P. ganglbaueri) and the corolla tube length of Zaluzianskya microsiphon, a flowering plant endemic to South Africa.

The species–area relationship or species–area curve describes the relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area. Larger areas tend to contain larger numbers of species, and empirically, the relative numbers seem to follow systematic mathematical relationships. [1]
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
A program that focuses on the relationships and interactions that range across levels of biological organization based on a scientific study is Ecology and Evolutionary Biology. The origins and history of ecosystems, species, genes and genomes, and organisms, and how these have changed over time is all part of the studies of how biodiversity ...
A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
The Princeton University Press reprinted the book in 2001 as a part of the "Princeton Landmarks in Biology" series. [1] The book popularized the theory that insular biota maintain a dynamic equilibrium between immigration and extinction rates. The book also popularized the concepts and terminology of r/K selection theory. [2]
The relationship between ecosystem complexity and stability is a major topic of interest in ecology.Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem.
The species-area relationship equation is: =. [10] An example of what a species-area relationship may look like when graphed. In this equation, represents the measure of diversity of a species (for example, the number of species) and is a constant representing the y-intercept.
