Pohlia Filiformis
''Anomobryum julaceum'', the slender silver-moss, is a species of bryophyte native to all continents except South America and Antarctica. ''A. julaceum'' is found widespread in the temperate regions of the Northern and Southern Hemispheres. Its capsules mature beginning in late fall and through the spring. It is most commonly found in wet crevices and on sandstone cliffs. Additional micro-habitats include tussock tundra with seeps and late snow melt areas and on granitic outcrops. In eastern North America it appears to be restricted to acid habitats, in the wet crevices of sandstone cliffs or other seepy niches. Overall, ''A. julaceum'' resembles species of the genus ''Pohlia'', and its leaves are similar to those of ''Bryum argenteum''; it can only be separated from ''Pohlia'' and ''Bryum'' using a microscope. ''Anomobryum julaceum'' can be distinguished from ''Bryum argenteum'' by its strongly julaceous, shiny leaves. Taxonomic history A number of names have been used for thi ...

James Dickson (biologist)
James (Jacobus) J. Dickson (1738–1822) was a Scottish nurseryman, plant collector, botanist and mycologist. Between 1785 and 1801 he published his ''Fasciculus plantarum cryptogamicarum Britanniae'', a four-volume work in which he published over 400 species of algae and fungi that occur in the British Isles''Jacobi Dickson Fasciculus (-fasciculus quartus) plantarum Cryptogamicarum Britanniæ''. MS. notes. 4 fasc. pl. XII. Prostant venales apud auctorem; G. Nicol: Londini, 1785-1801. 4º. (2 copies in the British Library) He is also the author of ''Collection of Dried Plants, Named on the Authority of the Linnaean Herbarium and Other Original Collections''. The plant genus ''Dicksonia'' is named after him. Life He was born at Kirke House, Traquair, Peeblesshire, of poor parents, and began life in the gardens of the Earl of Traquair. While still young he went to Jeffery's nursery-garden at Brompton, and in 1772 started in business for himself in Covent Garden. Dickson made seve ...

Ohio Department Of Natural Resources
The Ohio Department of Natural Resources (ODNR) is the Ohio state government agency charged with ensuring "a balance between wise use and protection of our natural resources for the benefit of all." ODNR regulates the oil and gas industry, the mining industry, hunting and fishing, and dams, while maintaining natural resources such as state parks, state nature preserves, state wildlife areas, state forests, and state waterways. It was created in 1949 by the Ohio Legislature. ODNR owns and manages more than 640,000 acres of land including 75 state parks, 23 state forests, 136 state nature preserves and 150 wildlife areas. The department has jurisdiction over more than 61,500 miles of inland rivers and streams, 451 miles of the Ohio River and 2.29 million acres of Lake Erie. ODNR is responsible for overseeing and permitting all mineral extraction, monitoring dam safety, managing water resources and mapping the state's major geologic structures and mineral resources.

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryum Argenteum
''Bryum argenteum'', the silvergreen bryum moss or silvery thread moss, is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope. Description The species is silvery-green or whitish-green colored when dry. This is because the broadly ovate shaped single leaflets in the tip do not form chlorophyll. The costa extends beyond the middle of the leaf. In damp, undisturbed locations, the branches may also form a more horizontal growth habit. The upper cells of the leaf surface are elongated rhomboid shaped. The capsule of the sporophyte is short cylindrical, appears broader at the base and is dark red to black colored. It has a high ability to tolerate drought and pollution of urban environments. ''B. argenteum'' is considered a desiccation tolerant species that can withstand total drying. While it is a common characteristic in mosses, ''B. argenteum'' was one of the first bryophytes experimentall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pohlia
''Pohlia'' is a genus of mosses in the family Mniaceae, found on all continents including Antarctica. Some of its species are native to multiple continents.

Hermann Solms-Laubach
Hermann zu Solms-Laubach, more precisely Hermann Maximilian Carl Ludwig Friedrich Graf zu Solms-Laubach (23 December 1842 in Laubach, Grand Duchy of Hesse – 24 November 1915 in Strasbourg) was a German botanist. Life Count Solms-Laubach studied in Giessen, Berlin, Fribourg and Geneva. In 1868 he obtained habilitation at the University of Halle-Wittenberg. In 1872 he became an associate professor at the University of Strasbourg; in 1879 he was appointed professor and director of the botanical garden in Göttingen, and in 1888 in Strasbourg. From October 1883 to March 1884 he traveled in Java and stayed for 3 months at Buitenzorg (now Bogor, especially in the botanical garden), West Java and made several collections in the vicinity of Cibodas. He wrote a paper about the Bogor Botanical Gardens that he loved so much.

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sporangium
A sporangium (; from Late Latin, ) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other lineages form sporangia at some point in their life cycle. Sporangia can produce spores by mitosis, but in nearly all land plants and many fungi, sporangia are the site of meiosis and produce genetically distinct haploid spores. Fungi In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction. The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae. Although sexual reproduction in fungi varies between phyla, for some fungi the sporangium plays an indirect role in sexual reprod ...
