Edmund Russow
Edmund August Friedrich Russow (russian: Эдму́нд Фридрихович Ру́ссов, translit=Èdmúnd Fridrichovič Rússov; – ) was a Baltic German biologist. Academic career Son of a military engineer, Edmund Russow studied at the Universities of Dorpat (now Tartu, Tartu County, Estonia) and Berlin. In 1867 he became an associate professor at Dorpat, where from 1874 to 1897, he served as a full professor. In 1895-97 he was president of the Estonian Naturalists' Society. Russow was at the forefront of nature conservation in Estonia, and associated with the work of Hugo Conwentz (1865-1922), a founder of nature conservation efforts throughout Europe. Botanical work Russow was an authority on Sphagnaceae (sphagnum mosses) and remembered for his research in plant anatomy and histology, in particular studies of the plant family Marsileaceae (aquatic and semi-aquatic ferns). The plant genus '' Russowia'' is named in his honor, as is ''Sphagnum russowii'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peat Moss
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat 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 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225-229. The empty cells help retain water in drier conditions. As sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, sphagnum can influence the composition of such habitats, with some describing sphagnum as 'habitat manipulators'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and ericaceous shrubs, as well as orchids and carnivorous plants.Keddy, P ...

Boreal Kingdom
The Boreal Kingdom or Holarctic Kingdom (Holarctis) is a floristic kingdom identified by botanist Ronald Good (and later by Armen Takhtajan), which includes the temperate to Arctic portions of North America and Eurasia. Its flora is inherited from the ancient supercontinent of Laurasia. However, parts of the floristic kingdom (and most of its Circumboreal Region) were glaciated during the Pleistocene and as a consequence have a very young flora. Cenozoic relicts found refuge in the southern and mountainous parts of the kingdom, especially in the Eastern Asiatic Region and southern North American Atlantic Region. Good noted that many plant species of temperate North America and Eurasia were very closely related, despite their separation by the Atlantic Ocean and the Bering Strait. Millions of years ago, before the opening of the Atlantic Ocean, North America and Eurasia were joined as a single continent, Laurasia. After the opening of the Atlantic, the continents were con ...
