In other words, a cultural keystone species is not just important culturally; the species, and the cultural practices that surround it, are also essential to the health and structure of the broader ecosystem. They are, in Loring's words, "a point of convergence... where our intersections are intrinsically powerful, meaningful and symbolic." [10]
[5] [6] Richard D. Ryder, who coined the term, defined it as "a prejudice or attitude of bias in favour of the interests of members of one's own species and against those of members of other species". [7] Speciesism results in the belief that humans have the right to use non-human animals in exploitative ways which is pervasive in the modern ...
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
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 coevolution, where the existence of one species is tightly bound up with the life of another species, new or 'improved' adaptations which occur in one species are often followed by the appearance and spread of corresponding features in the other species. In other words, each species triggers reciprocal natural selection in the other.
In other words, these mechanisms "encourage" an individual to compete more with other individuals of its own species, rather than with individuals of other species. Resource partitioning (a type of niche differentiation ) is a stabilizing mechanism because interspecific competition is reduced when different species primarily compete for ...
A species that is brought to a new area, country, or bioregion for a specific purpose, such as for a garden or lawn; a crop species; a landscaping species; a species that provides food; a groundcover species; for soil stabilization or hydrological control; for aesthetics or familiarity of the species; or other purposeful reasons (Booth et al ...
Inter-sexual mimicry (a type of automimicry, as it is within a single species) occurs when individuals of one sex in a species mimic members of the opposite sex to facilitate sneak mating. An example is the three male forms of the marine isopod Paracerceis sculpta. Alpha males are the largest and guard a harem of females. Beta males mimic ...
