Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Blue Mesa Reservoir
Blue Mesa Reservoir is an artificial reservoir located on the upper reaches of the Gunnison River in Gunnison County, Colorado. The largest lake located entirely within the state, Blue Mesa Reservoir was created by the construction of Blue Mesa Dam, a 390-foot tall earthen fill dam constructed on the Gunnison by the U.S. Bureau of Reclamation in 1966 for the generation of hydroelectric power. Managed as part of the Curecanti National Recreation Area, a unit of the National Park Service, Blue Mesa Reservoir is the largest lake trout and Kokanee salmon fishery in Colorado. History In 1956, the U.S. Bureau of Reclamation was given the responsibility, under the Colorado River Storage Project Act, to begin planning and construction of the Colorado River Storage Project (CRSP), a series of projects in Colorado, New Mexico, Utah, and Wyoming that would make possible comprehensive development of the waters of the Colorado River and its major tributaries. One of the initial projects of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...

Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise 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 leaves that are generally only one cell thick, attached to a 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 spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.

Selaginella Densa
''Selaginella densa'' is a species of spikemoss known by the common names lesser spikemoss, prairie spikemoss, and Rocky Mountains spikemoss. It is native to western North America, where it can be found from Alaska to Ontario, the Dakotas, Texas and far northern California. It grows in many types of habitat, from grassland to the alpine climates of high mountains, in rocky and sandy areas. It is a dominant plant in many types of prairie on the Great Plains, especially shortgrass prairie, where it grows alongside dominant grasses. It grows in windy, exposed, snow-free rock outcrops on mountain peaks in several ranges, including the Cascade Range and the Front Range of the Rocky Mountains. It is most common on dry soils in open areas, tolerating desiccation relatively easily. This lycophyte forms mats or cushions of creeping stems which fork into small, upright branches. The green, linear or lance-shaped leaves are up to 5 millimeters long including the short, soft bristles on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribes Cereum
''Ribes cereum'' is a species of currant known by the common names wax currant and squaw currant; the ''pedicellare'' variety is known as whisky currant. The species is native to western North America. Description ''Ribes cereum'' is a spreading or erect shrub growing between and in height. The stems are fuzzy, often very glandular, and lack spines and prickles. The gray-green leaves are somewhat rounded and divided into shallow lobes which are toothed along the edges. The leaves are hairless to quite hairy and usually studded with visible resin glands, particularly around the edges. The inflorescence is a clustered raceme of 2 to 9 flowers. The small flower is tubular with the white to pink sepals curling open at the tips to form a corolla-like structure. Inside there are minute white or pinkish petals, five stamens, and two protruding green styles. The fruit is a rather tasteless orange-red berry up to wide, with a characteristically long, dried flower remnant at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
