David Heinrich Hoppe
David Heinrich Hoppe (15 December 1760 – 1 August 1846) was a German pharmacist, botanist, entomologist and physician. He is remembered for contributions made to the study of alpine flora. Life Hoppe, a merchant's son from Vilsen, Hanover, began his career as a pharmacy apprentice in Celle, and subsequently was an assistant pharmacist in Hamburg, Halle, Wolfenbüttel and Regensburg. From 1792 onwards, he studied medicine and natural sciences at the University of Erlangen, and following graduation returned to Regensburg as a physician. Here he taught classes at the Regensburg lyceum. He studied the flora of the Danube region surrounding Regensburg. In June 1798 he first explored the Untersberg massif near Salzburg, and almost each summer until 1843 continued his botanical excursions from Salzburg into the Eastern Alps. With bryologist Christian Friedrich Hornschuch (1793–1850), he published a treatise involving an extended scientific journey to the Adriatic coast and the mou ...

Eriophorum
''Eriophorum'' (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found in the cool temperate, alpine, and Arctic regions of the Northern Hemisphere, primarily in the middle latitudes of North America, Europe, and Asia. Description ''Eriophorium'' species are perennial herbaceous plants that persist by means of underground rhizomes. Stems (called culms) grow singly or in clumps (i.e., cespitose). Both basal leaves and stem leaves are present, although the latter are bladeless in some species. The terminal inflorescence is either a single erect spikelet or multiple spikelets on peduncles of various lengths. In the case of multiple spikelets, the inflorescence is subtended by one or more leaf-like bracts. Individual flowers have 10 or more smooth perianth bristles that greatly elongate and remain attached to the achene during fruiting. The bristles facilitate seed dispersal by wind. In cold Arctic region ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muskox
The muskox (''Ovibos moschatus'') is a hoofed mammal of the family Bovidae. Native to the Arctic, it is noted for its thick coat and for the strong odor emitted by males during the seasonal rut, from which its name derives. This musky odor has the effect of attracting females during mating season. Its Inuktitut name "umingmak" translates to "the bearded one". Its Woods Cree names "mâthi-môs" and "mâthi-mostos" translate to "ugly moose" and "ugly bison", respectively. In historic times, muskoxen primarily lived in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut. They were formerly present in Eurasia, with their youngest natural records in the region dating to around 2,700 years ago, with reintroduced populations in the American state of Alaska, the Canadian territory of Yukon, and Siberia, and an introduced population in Norway, part of which emigrated to Sweden, where a small population now lives.

North Baffin
The North Baffin dialect (''Qikiqtaaluk uannangani'' or ''Iglulingmiut'') of Inuktitut is spoken on the northern part of Baffin Island, at Igloolik and the adjacent part of the Melville Peninsula, and in other Inuit communities in the far north of Nunavut, like Resolute, Grise Fiord, Pond Inlet, Clyde River, and Arctic Bay. The governments of Nunavut and the Northwest Territories generally consider it to be a dialect of Inuktitut, due to its location in Nunavut, as do some linguists, but it is instead sometimes classified as a dialect of Inuvialuktun. However, Inuktitut and Inuvialuktun form a dialect continuum A dialect continuum or dialect chain is a series of Variety (linguistics), language varieties spoken across some geographical area such that neighboring varieties are Mutual intelligibility, mutually intelligible, but the differences accumulat ... with few sharp boundaries.

Inuit
Inuit (singular: Inuk) are a group of culturally and historically similar Indigenous peoples traditionally inhabiting the Arctic and Subarctic regions of North America and Russia, including Greenland, Labrador, Quebec, Nunavut, the Northwest Territories, Yukon (traditionally), Alaska, and the Chukotsky District of Chukotka Autonomous Okrug. The Inuit languages are part of the Eskaleut languages, also known as Inuit-Yupik-Unangan, and also as Eskimo–Aleut. Canadian Inuit live throughout most of Northern Canada in the territory of Nunavut, Nunavik in the northern third of Quebec, the Nunatsiavut in Labrador, and in various parts of the Northwest Territories and Yukon (traditionally), particularly around the Arctic Ocean, in the Inuvialuit Settlement Region. These areas are known, by Inuit Tapiriit Kanatami and the Government of Canada, as Inuit Nunangat. In Canada, sections 25 and 35 of the Constitution Act of 1982 classify Inuit as a distinctive group of Abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carex Aquatilis
''Carex aquatilis'' is a species of Carex, sedge known as water sedge and leafy tussock sedge. It has a Circumboreal Region, circumboreal distribution, occurring throughout the northern reaches of the Northern Hemisphere. It grows in many types of mountainous and arctic habitat, including temperate coniferous forest, alpine tundra, alpine meadows, tundra, and wetlands. There are several varieties of this species, and it is somewhat variable in appearance. It produces triangular stems reaching heights between and , and generally does not form clumps as some other sedges do. It grows from a dense rhizome network which produces a mat of fine roots thick enough to form sod, and includes aerenchyma to allow the plant to survive in low-oxygen substrates like heavy mud. The inflorescence bears a number of spikes with one leaflike bract at the base which is longer than the inflorescence itself. The fruits are glossy achenes, and although the plant occasionally reproduces by seed, most of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moss
Mosses are small, non-vascular plant, non-vascular flowerless plants in the taxonomic phylum, division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Wilhelm Philippe Schimper, Schimp. 1879) may also refer to the parent group bryophytes, which comprise Marchantiophyta, liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaf, leaves that are generally only one cell thick, attached to a plant stem, stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing sporangium, spores. They are typically tall, though some species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Meadow
A wet meadow is a type of wetland with soils that are Solubility, saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Hydrology and ecology Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of Flood, inundation and longer periods of Hydric soil, saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do ...

Helophyte
Aquatic plants, also referred to as hydrophytes, are vascular plants and non-vascular plants that have adapted to live in aquatic environments ( saltwater or freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.Sculthorpe, C. D. 1967. The Biology of Aquatic Vascular Plants. Reprinted 1985 Edward Arnold, by London.Hutchi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern.
