Plant cells use a variety of signals such the oxygen concentration, [9] plant hormones like ethylene, [10] [11] energy and sugar status [12] [13] to acclimate to waterlogging-induced oxygen deprivation. Roots can survive waterlogging by forming aerenchyma, inducing anaerobic metabolism, and changing root system architecture. [14]
Water management is the process of planning, developing, and managing water resources across all water applications, in terms of both quantity and quality." Water management is supported and guided by institutions, infrastructure, incentives, and information systems [39] The issue of the depletion of fresh water has stimulated increased efforts ...
The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife.
Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, [2] introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples.
Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of microorganisms that may deplete the oxygen of water. [ 1 ] [ 2 ] Eutrophication may occur naturally or as a result of human actions.
