Naturalisation (or naturalization) is the ecological phenomenon through which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. [1]
Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity. [15]
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
A reduction in the fitness (biology) of a population is a direct consequence of its low diversity which is dependent on the expression of deleterious recessive alleles. In large populations, natural selection keeps such alleles at a low frequency. Since they usually occur in heterozygotes, they are masked by a copy of “normal alleles”.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
A Look At Japan's Reverse Housing Crisis Where Millions Of Homes Sit Vacant. Japan's housing industry is facing the reality that it is possible to have "too much of a good thing."
Traditional conservation is based on "reservation and restoration"; reservation meaning setting pristine lands aside for the sole purpose of maintaining biodiversity, and restoration meaning returning human impacted ecosystems to their natural state.
Allogenic engineers modify the biophysical environment by mechanically changing living or nonliving materials from one form to another. Beavers are the original model for ecosystem engineers; in the process of clearcutting and damming, beavers alter their ecosystem extensively.
