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 ...
Compared to other Sphagnum species, Sphagnum squarrosum retains fewer spores within its capsules after dispersal, resulting in greater spore release and wider distribution. [ 9 ] Research on island colonization reveals that S. squarrosum is an effective long-distance disperser, successfully establishing populations as far as 40 km (25 mi) from ...
Sphagnum fimbriatum faces the same threats as other European wetland species: habitat drainage for agriculture, nutrient pollution from farming, dam construction, and peat extraction. The species shows more resilience than other bog-mosses through effective spore dispersal and colonisation.
Molecular phylogenetics, and other techniques such as ultrastructure analysis, has greatly increased the understanding of chytrid phylogeny, and led to the formation of several new zoosporic fungal phyla: The order Blastocladiales, originally within the Chytridiomycota, are now classified as a separate phylum, the Blastocladiomycota.

Hygromorphy is a common mechanism of seed dispersal as the movement of dead tissues respond to hygrometric variation, [11] e.g. spore release from the fertile margins of Onoclea sensibilis. Movement occurs when plant tissue matures, dies and desiccates, cell walls drying, shrinking; [ 12 ] and also when humidity re-hydrates plant tissue, cell ...
Blue: A spore bearing a trilete mark – the Y-shaped scar. The spores are about 30–35 μm across. The spores are about 30–35 μm across. Palynology is the study of microorganisms and microscopic fragments of mega-organisms that are composed of acid-resistant organic material and occur in sediments , sedimentary rocks , and even some ...
Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. [1] The act of dispersal involves three phases: departure, transfer, and settlement. There are different fitness costs and benefits associated with each of these ...
Sphagnum angustifolium, the fine bogmoss, [2] is a species of peat moss with a Holarctic distribution. A member of the S. recurvum species complex within Sphagnum section Cuspidata, it is a relatively small, green to yellowish moss that grows in wet, moderately nutrient-rich mires, typically forming carpets or growing intermixed with other peat moss species.
