Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Betula Pubescens
''Betula pubescens'' (syn. ''Betula alba''), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch (''B. pendula''), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (''B. nana''). Six varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed but many are no longer in cultivation. The larva of the autumnal moth (''Epirrita autumnata'') feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. The tree is a pioneer species ...

Salix Lanata
''Salix lanata'', the woolly willow, is a subarctic species of willow native to Iceland, the Faeroe Islands and Finland, through to eastern Siberia. In Scotland it can be found in only a few localities of Perthshire, Angus and Aberdeenshire, generally on rocky mountain sides at altitudes of .Willows and Poplars of Great Britain and Ireland, BSBI Handbook No. 4; Meikle; 1984. Description ''Salix lanata'' is a low, many-branched, deciduous shrub, generally less than high by broad. The new twigs are hairy at first, soon becoming hairless and brown. The grey-green leaves are rather variable, but generally ovate up to long by up to wide, covered in silvery-grey "wool" to begin with but less so with age. The leaf margins are usually entire. The catkins appear in summer (May to July), with male and female catkins on separate plants (like all willows this species is dioecious). The female catkins are densely hairy. The petioles are usually less than 1 cm long, and the stipules ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mycosphaerella
''Mycosphaerella'' is a genus of ascomycota. With more than 10,000 species, it is the largest genus of plant pathogen fungi. The following introduction about the fungal genus ''Mycosphaerella'' is copied (with permission) from the dissertation of W. Quaedvlieg (named: Re-evaluating ''Mycosphaerella'' and allied genera). Species belonging to the fungal genus ''Mycosphaerella'' (1884) (''Capnodiales'', ''Dothideomycetes'') have evolved as endophytes, saprotrophs and symbionts, but mostly ''Mycosphaerella'' species are foliicolous plant pathogens which are the cause of significant economical losses in both temperate and tropical crops worldwide. The generic concept of Mycosphaerella is based on the type species of the genus, ''M. punctiformis'', which was introduced \130 years ago in order to describe small loculoascomycetes with few distinct morphological traits. Species belonging to ''Mycosphaerella'' were characterised as having pseudothecial ascomata that can be immersed or sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
