Sphagnum is a genus of approximately 380 accepted species [2] [3] of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 ...
Sphagnum palustre (Syn. Sphagnum cymbifolium), the prairie sphagnum [1] or blunt-leaved bogmoss, [2] is a species of peat moss from the genus Sphagnum, in the family Sphagnaceae. Like other mosses of this type it can soak up water up to the 30-fold amount of its own dry weight thanks to its elastic spiral fibers.
In the 2010s Sphagnum peat in Chile has begun to be harvested at large scales for export to countries like Japan, South Korea, Taiwan and the United States. Given Sphagnums property to absorb excess water and release it during dry months harvesting of Sphagnum, means that overexploitation may threaten the water supply in the fjords and channels of Chile.

Most are focused on Sphagnum and reed farming. Rather than excavating decomposed Sphagnum as peat, non-decomposed reed fibres are harvested in cycles, as a renewable source of biomass. Sphagnum fibres can be used as a growing substrate, packaging to protect plants in transport, or to reintroduce moss when restoring other peatlands.
However, subtropical wetlands have shown high CO 2 binding per mol of released methane, which is a function that counteracts global warming. [39] Tropical peatlands are suggested to contain about 100 Gt carbon, [ 40 ] [ 30 ] corresponding to more than 50% of the carbon present as CO 2 in the atmosphere. [ 2 ]
[2] [3] They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. [4] [5] Bogs occur where the water at the ground surface is acidic and low in nutrients. A bog usually is found at a freshwater soft spongy ground that is made up ...
A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage of development of the gametophyte (the haploid phase) in the life cycle of mosses. When a moss first grows from a spore , it starts as a germ tube , which lengthens and branches into a filamentous complex known as a protonema , which develops into a ...
Proposition 2: The form, power, content, and direction of the proximal processes effecting development vary systematically as a joint function of the characteristics of the developing person; of the environment—both immediate and more remote—in which the processes are taking place; the nature of the developmental outcomes under ...
