In ecology, a population consists ofall the organisms of a given species that live in a particular area. The statistical study of populations and how they change over time is called demography. ... A population can also be described in terms of the distribution, or dispersion, of the indivi...

While this factor may also contribute, observations suggest that [#highlight4]phytoplankton populations rise and fall much more quickly than nutrient concentrations change[/highlight4]. [#paragraph4]Yet another explanation is that species succession is a consequence of changes in seawater brought about...
when a community is disturbed so much that the species composition and relative abundance of populations in the community change, and the new community structure is resistant to further change (requires large disturbance like keystone species being removed) communtiy assemblage of species living together...
Parasite An organism that feeds on a living host Population individuals that belong to the same species and live in the same area Community different populations that live together in an area Symbiosis A close relationship between two species that benefits at least one of the species Carrying Capac...
(Kemaet al.1996c), consistent with the overwhelming evidence for recombination among molecular markers in natural populations (Chen and McDonald 1996; McDonaldet al.1999).Mendelian inheritanceof both biological and molecular markers occurred despite the large karyotypic differentiation observed among ...
