Sphagnum is a genus of approximately 380 accepted species [2] [3] ... Sporophytes are raised on stalks to facilitate spore dispersal, but unlike other mosses, ...
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.
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 ...
Most mosses rely on the wind to disperse the spores. In the genus Sphagnum the spores are projected about 10–20 cm (4–8 in) off the ground by compressed air contained in the capsules; the spores are accelerated to about 36,000 times the earth's gravitational acceleration g. [23] [24]
Extremely fast movements such as the explosive spore dispersal techniques of Sphagnum mosses may involve increasing internal pressure via dehydration, causing a sudden propulsion of spores up or through the rapid opening of the "flower" opening triggered by insect pollination.
Explosive dehiscence is a ballistic form of dispersal that flings seeds or spores far from the ... Explosive dehiscence of sporangia is a characteristic of Sphagnum. [1]
At that time, the elaters uncoil to extend out from the spore and will catch air currents. The fact that they are extended only when conditions are dry means that successful spore dispersal is more likely. The mature strobili of a horsetail (Equisetum arvense). A cross section through a horsetail strobilus, showing spores with elaters.
Sphagnum wulfianum, commonly known as Wulf's peatmoss, is a species of moss belonging to the family Sphagnaceae.It has a circumboreal distribution, occurring primarily in moist boreal forest environments across Eurasia and North America, with rare occurrences in Arctic tundra regions.
