Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some ...
an ecocline is a variation of the physicochemical environment dependent of one or two physico-chemical factors of life, and thus presence/absence of certain species. [9] An ecocline can be a thermocline , chemocline (chemical gradient), halocline (salinity gradient) or pycnocline (variations in density of water induced by temperature or salinity).
The shortgrass prairie is an ecosystem located in the Great Plains of North America.The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula).
A "keystone species" is a species that "has disproportionate importance in their community." [8] Keystone species on the great plains include the bison and the prairie dog. Many other species live on the grasslands, including deer, rabbits, mice, and many types of birds.
Grasslands — also known as savannas, prairies, steppes and pampas — are ecosystems found in parts of the world that do not get sufficient consistent rainfall to support forest growth, but get ...
A keystone species is a species that is connected to a disproportionately large number of other species in the food-web. Keystone species have lower levels of biomass in the trophic pyramid relative to the importance of their role. The many connections that a keystone species holds means that it maintains the organization and structure of ...
keystone species - a species that has a disproportionate effect on its environment relative to its abundance, affecting many other organisms in an ecosystem and help in determine the types and numbers of various others species in a community. Kyoto Protocol - an international agreement adopted in December 1997 in Kyoto, Japan. The Protocol sets ...
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 ...
