Sweet Grass Hills
The Sweet Grass Hills (Blackfoot: ''kátoyissiksi'', Cheyenne: ''vé'ho'ôhtsévóse'', Salish: ''ččaɫalqn '', "three peaks") are a small group of low mountains rising more than 3,000 feet above the surrounding plains southwest of Whitlash, Montana in Liberty and Toole County, Montana. The tallest point in the hills is West Butte at . Quite prominent in the local area, they are clearly visible from US Highway 2 to the south, I-15, and can sometimes be seen as far North as the Crowsnest Highway ( Highway 3) near Medicine Hat in Alberta as well as from the West, near Glacier National Park and Browning, Montana. Other named peaks in the small group are Gold Butte (6,512 feet), East Butte (with two peaks, the taller of which at 6,958 ft), and Mount Lebanon (5807 ft). The Sweet Grass Hills are an example of the island ranges that dot the central third portion of the state of Montana. These island ranges, completely surrounded by the 'sea' of plains and not geographical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montana
Montana () is a state in the Mountain West division of the Western United States. It is bordered by Idaho to the west, North Dakota and South Dakota to the east, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, the eighth-least populous state, and the third-least densely populated state. Its state capital is Helena. The western half of Montana contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state. Montana has no official nickname but several unofficial ones, most notably "Big Sky Country", "The Treasure State", "Land of the Shining Mountains", and " The Last Best Place". The economy is primarily based on agriculture, including ranching and cereal grain farming. Other significant economic resources include oil, gas, coal, mining, and lumber. The health ca ...

Pendant
A pendant is a loose-hanging piece of jewellery, generally attached by a small loop to a necklace, which may be known as a "pendant necklace". A pendant earring is an earring with a piece hanging down. Its name stems from the Latin word ''pendere'' and Old French word ''pendr'', both of which translate to "to hang down". In modern French, ''pendant'' is the gerund form of ''pendre'' ("to hang") and also means "during". The extent to which the design of a pendant can be incorporated into an overall necklace makes it not always accurate to treat them as separate items. In some cases, though, the separation between necklace and pendant is far clearer. Overview Pendants are among the oldest recorded types of bodily adornment. Stone, shell, pottery, and more perishable materials were used. Ancient Egyptians commonly wore pendants, some shaped like hieroglyphs. Pendants can have several functions, which may be combined: * Award (i.e., Scouting Ireland Chief Scout's Award, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holdfast (biology)
A holdfast is a root-like structure that anchors aquatic sessile organisms, such as seaweed, other sessile algae, stalked crinoids, benthic cnidarians, and sponges, to the substrate. Holdfasts vary in shape and form depending on both the species and the substrate type. The holdfasts of organisms that live in muddy substrates often have complex tangles of root-like growths. These projections are called haptera and similar structures of the same name are found on lichens. The holdfasts of organisms that live in sandy substrates are bulb-like and very flexible, such as those of sea pens, thus permitting the organism to pull the entire body into the substrate when the holdfast is contracted. The holdfasts of organisms that live on smooth surfaces (such as the surface of a boulder) have flattened bases which adhere to the surface. The organism derives no nutrition from this intimate contact with the substrate, as the process of liberating nutrients from the substrate requires ...

Isidia
An isidium is a vegetative reproductive structure present in some lichens. Isidia are outgrowths of the thallus surface, and are corticated (i.e., containing the outermost layer of the thallus), usually with a columnar structure, and consisting of both fungal hyphae (the mycobiont) and algal cells (the photobiont). They are fragile structures and may break off and be distributed by wind, animals, and splashing raindrops. In terms of structure, isidia may be described as warty, cylindrical, clavate (club-shaped), scale-like, coralloid (coral-shaped), simple, or branched. Examples of isidiate lichens include members of the genera ''Parmotrema'' and ''Peltigera''. See also Soredium Soredia are common reproductive structures of lichens. Lichens reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungal hyphae wrapped around cyanobacteria o ...

Usnea Filipendula
''Usnea filipendula'', the fishbone beard lichen, is a pale gray-green fruticose lichen with a pendant growth form, growing in up to 20 cm many-branching tassels hanging from the bark of trees. In California, it mostly grows on mostly conifer in the Coast Range, but also in the western slopes of the Sierra Nevada range.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, It lacks apothecia. It is similar to '' Usnea scabrata'', but is darker, has a thicker cortex, and different chemistry. Lichen spot tests are K+ red, KC−, C−, and P+ yellow. References filipendula ''Filipendula'' is a genus of 12 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere.

Usnea
''Usnea'' is a genus of mostly pale grayish-green fruticose lichens that grow like leafless mini-shrubs or tassels anchored on bark or twigs.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The genus is in the family Parmeliaceae. It grows all over the world. Members of the genus are commonly called old man's beard, beard lichen, or beard moss. Like other lichens it is a symbiosis of two or three fungi and an alga. In ''Usnea'', the fungus belongs to the division Ascomycota, while the alga is a member of the division Chlorophyta. Members of the genus are similar to those of the genus '' Alectoria''. A distinguishing test is that the branches of ''Usnea'' are somewhat elastic, but the branches of ''Alectoria'' snap cleanly off. Systematics The genus ''Usnea'' was circumscribed by Michel Adanson in 1763. He used the name designated by Johann Jacob Dillenius, whose earlier published description did not met the rules of valid publication as estab ...

Lichens Of North America
Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University. Brodo's list of publications includes 75 research papers, 8 popular articles, 22 reviews and 6 editorials and obituaries. In 1993, Brodie was awarded the Mary E. Elliot Service Award for his meritorious service to the Canadian Botanical Association. One of Irwin Brodo's great achievements was the public ...
