Floating Mat
A floating mat () is a layer of mosses and other, especially stoloniferous, plants that grows out from the shore across the surface of a lake or pond. This type of habitat is protected and is designated in the European Habitats Directive as "LRT No. 7140 Transition and Floating Mat Bogs". Landscapes with floating mats are characterized as quagmires. Floating mats are not always capable of bearing weight. There is a risk of drowning when walking on them. Formation The formation of floating mats is a process of sedimentation in water bodies. In bog ponds, floating mats of peat moss form as water levels fall and nutrient (plant), nutrients accumulate. In eutrophic waters, the formation of floating mats is caused by underwater peat that floats to the surface and is colonised by plants. The vegetative mats are held together by their root systems. Phragmites, Reeds or juncus, rushes growing by the lakeshore can eventually cut these mats off, which results in a floating island. ...

Feathery Bogmoss
Feathers are epidermis (zoology), epidermal growths that form a distinctive outer covering, or plumage, on both Bird, avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and an example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant Aves, birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and crypsis, protection. The study of feathers is called plumology (or plumage science). People use feathers in many ways that are practical, cultural, and religious. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
