The Ogallala aquifer, or the High Plains aquifer, is an integral fresh water source for the entirety of the Great Plains region, providing drinking water to 80% of the population and irrigating 13 million acres of land. Precipitation, seasonal lakes, and prehistoric water reserves serve as sources of water for the aquifer, which lies beneath ...
Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [ 1 ]
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
In ecology, allogenic succession is succession driven by the abiotic components of an ecosystem. [1] In contrast, autogenic succession is driven by the biotic components of the ecosystem. [1] An allogenic succession can be initiated in a number of ways which can include: Volcanic eruptions; Meteor or comet strike; Flooding; Drought; Earthquakes
Early ecological succession theory maintained that the directional shifts from one stage of succession to the next were induced by the plants themselves. [1] In this sense, succession theory implicitly recognized priority effects; the prior arrival of certain species had important impacts on future community composition.
Water levels in wells across Texas are running low because of the extreme drought, groundwater experts say. ... 97% of Texas was in a drought, affecting 24.1 million Texans, per the U.S. Drought ...
These water bodies include some of the largest and most ecologically productive coastal estuaries in the United States and contribute significantly to the ecological and economic resources of Texas. They are included in a number of national protected areas such as National Wildlife Refuges , a National Seashore , and a National Estuarine ...
Some regions of Texas have already run out of water — and the rest face a looming crisis, the state’s agriculture commissioner said on Sunday. “We lose about a farm a week in Texas, but it ...
