With the exception of rice (Oryza sativa), [4] [5] most crops like maize and potato, [6] [7] [8] are therefore highly intolerant to waterlogging. 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 ...
moss bog) is a peat-forming ecosystem found in several northern climates, most commonly in Arctic and boreal areas. Muskeg is approximately synonymous with bog or peatland, and is a standard term in Canada and Alaska. The term became common in these areas because it is of Cree origin; maskek (ᒪᐢᑫᐠ) meaning "low-lying marsh". [1]
The major archaeological problem with waterlogged finds, particularly wood, is that they deteriorate rapidly when they are uncovered, beginning to dry and crack almost at once. They therefore need to be kept wet until treated in a laboratory. Conservation measures explain why wet archaeology costs around four times as much as dry archaeology.
In 1629 mere and marsh were becoming interchangeable but in 1876 mere was 'heard, at times, applied to ground permanently under water': in other words, a very shallow lake. Where land similar to that of Martin Mere, gently undulating glacial till , becomes flooded and develops fen and bog , the remnants of the original mere remain until the ...
Eventually, peat builds up to a level where the land surface is too flat for ground or surface water to reach the center of the wetland. This part, therefore, becomes wholly rain-fed (ombrotrophic), and the resulting acidic conditions allow the development of bog (even if the substrate is non-acidic).
New Guinea is home to extensive swamp forests. These forests are permanently waterlogged or seasonally inundated during the rainy season. The Southern New Guinea freshwater swamp forests extend from the western Bird's Head Peninsula to the Papuan Peninsula in the southeast. The forests lie in the lower reaches of the rivers that drain New ...
The soil of the site, deriving from slate-based mudstones and siltstones, is permanently waterlogged in large places. It is the foundation for the largest area in Cornwall of Southern Atlantic wet heath, containing cross-leaved heath (Erica tetralix) and Dorset heath (Erica ciliaris). [1]
Surface and ground water stagnation; Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well as in natural containers, such as hollow tree trunks, leaf sheaths, etc. To avoid ground and surface water stagnation, the drainage of surface and subsoil is advised.
