Biological exponential growth is the unrestricted growth of a population of organisms, occurring when resources in its habitat are unlimited. [1] Most commonly apparent in species that reproduce quickly and asexually , like bacteria , exponential growth is intuitive from the fact that each organism can divide and produce two copies of itself.
The term population biology has been used with different meanings. In 1971, Edward O. Wilson et al. used the term in the sense of applying mathematical models to population genetics, community ecology, and population dynamics. [1] Alan Hastings used the term in 1997 as the title of his book on the mathematics used in population dynamics. [2]
DNA Data Bank of Japan (National Institute of Genetics) EMBL (European Bioinformatics Institute) GenBank (National Center for Biotechnology Information) DDBJ (Japan), GenBank (USA) and European Nucleotide Archive (Europe) are repositories for nucleotide sequence data from all organisms. All three accept nucleotide sequence submissions, and then ...
Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover ; [ 3 ] [ 4 ] using the transect method , as done for the mountain plover ; [ 5 ] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in ...
Evolutionary biology is the subfield of biology that studies the evolutionary processes such as natural selection, common descent, and speciation that produced the diversity of life on Earth.
Biochemistry is the study of chemical processes within and relating to living organisms. Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including molecular synthesis, modification, mechanisms, and interactions.
Population: Groups of organisms of the same species: Guild: Interspecific groups of organisms carrying the same ecological function (i.e. herbivores). Community (or biocoenosis) Guilds from all biological domains, and their interactions in a specific location. Ecosystem: Groups of organisms in conjunction with the physical environment. Biome
Two useful introductions to the fundamental theory underlying the unit of selection issue and debate, which also present examples of multi-level selection from the entire range of the biological hierarchy (typically with entities at level N-1 competing for increased representation, i.e., higher frequency, at the immediately higher level N, e.g., organisms in populations or cell lineages in ...
