Transpiration - Why Do Organisms Transpire Water?, Transpiration As An Ecological Process, Effects Of Human Activities On Transpiration
foliage surface evaporation refers
Transpiration refers to the evaporation of water from a biological surface, such as leaves, skin, or lungs. In its most common usage, however, transpiration refers to the loss of water from plant foliage, occurring through microscopic pores known as stomata. Transpiration is a component of a larger process known as evapotranspiration, which is the evaporation of water from a landscape, including both inorganic surfaces such as soil and bodies of water, and biological surface such as foliage.

Most transpiration by plants involves water that evaporates from the moist membranes of a tissue known as spongy mesophyll, which occur in the minute cavities beneath the tiny leaf pores called stomata. Stomata can be closed tightly using bordering cells known as guard cells. However, in most plants stomata are kept open much of the time. This is done so that carbon dioxide, which is needed for ph…
Transpiration is an ecologically important process. In areas where forests are common, evapotranspiration almost entirely occurs as transpiration, and this process can account for a substantial part of the manner by which the landscape deals with water inputs through rain and snow. For example, in typical forested landscapes of northeastern North America, evapotranspiration accounts for about 15-4…
The influence of an intact forest on evapotranspiration is affected by ecological disturbances, such as clear-cutting and wildfire. In general, these sorts of stand-level disturbances greatly reduce the transpiration component of evapotranspiration for several years, a change that influences other hydrological processes, such as the timing and amounts of stream flow, which may then have effects on…
