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.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The coefficient of relationship is a measure of the degree of consanguinity (or biological relationship) between two individuals. The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy.
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]
In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s [ 1 ] that is frequently used in sociobiology and evolutionary biology circles.
Interpersonal neurobiology (IPNB) or relational neurobiology is an interdisciplinary framework that was developed in the 1990s by Daniel J. Siegel, who sought to bring together scientific disciplines to demonstrate how the mind, brain, and relationships integrate.
The bees get their nutrients from the plants, and allow for successful fertilization of plants, demonstrating a mutualistic relationship between two seemingly-unlike species. Mutualism has also been linked to major evolutionary events, such as the evolution of the eukaryotic cell ( symbiogenesis ) and the colonization of land by plants in ...
In ecology, the occupancy–abundance (O–A) relationship is the relationship between the abundance of species and the size of their ranges within a region. This relationship is perhaps one of the most well-documented relationships in macroecology , and applies both intra- and interspecifically (within and among species).
