Charismatic species are often used as flagship species in conservation programs, as they are supposed to affect people's feelings more. [2] However, being charismatic does not protect species against extinction; all of the 10 most charismatic species are currently endangered, and only the giant panda shows a demographic growth from an extremely small population.
In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort.
An association can be viewed as a real, integrated entity shaped either by species interactions or by similar habitat requirements, or it can be viewed as merely a common point along a continuum. The former view was championed by American ecologist Frederic Clements , who viewed the association as a whole that was more than the sum of its parts ...
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.
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
In biology, gonochorism is a sexual system where there are two sexes and each individual organism is either male or female. [1] The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric. [2]: 212–222
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]
The scientific work of deciding how to define species has been called microtaxonomy. [ 26 ] [ 27 ] [ 20 ] By extension, macrotaxonomy is the study of groups at the higher taxonomic ranks subgenus and above, [ 20 ] or simply in clades that include more than one taxon considered a species, expressed in terms of phylogenetic nomenclature .
