"Most of the water used in the Great Plains comes from the High Plains aquifer (sometimes referred to by the name of its largest formation, the Ogallala aquifer), which stretches from South Dakota to Texas." [3] Conserving water in the Great Plains is one of the most important factors in keeping the Great Plains sustainable. It is also very ...
The Blackland Prairie was a disturbance maintained ecosystem prior to the arrival of Europeans. Fires ignited by lightning occasionally swept the area, clearing or reducing the encroachment of trees and shrubs on the prairie, while stimulating the native herbaceous prairie species of forbs and grasses which are pyrophytic , adapted and ...
Wet prairies may form in low-lying areas with poor drainage; dry prairie can be found on uplands or slopes. Dry prairie is the dominant habitat type in the Southern Canadian agricultural and climatic region which is known as Palliser's Triangle. It was once thought to be completely unarable, but is now one of the most important agricultural ...
Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...
The prairie around you. The Rolling Plains of Texas and Oklahoma are located between the tallgrass prairies of the east and the shortgrass prairies farther west and are mixed grass prairie ecosystems.
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).
The level to rolling Blackland Prairie characteristically has dark soils derived from underlying Cretaceous marl, chalk, and limestone. Prairie was common or dominant during and shortly after the Hypsithermal Period in the middle of the Holocene Epoch. By the late 18th century, the Blackland Prairie was a mosaic of woodland, savanna, and prairies.
An ecosystem is composed of biotic communities that are structured by biological interactions and abiotic environmental factors. Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.
