Alpine Lady Fern
''Athyrium distentifolium'' commonly known as alpine lady-fern is a perennial fern found in widely in the Northern Hemisphere. Description This plant is light green with a somewhat upright rootstock. The leaves, 30-70 cm, form as fascicle at the tip of the rootstock. The petiole is at most a fourth of the length of the leaf blade and scaled. The leaf blade is narrowing towards both the base and tip, repeatedly double pinnate. The leaflets are acuminate and pinnules are serrate or pinnately lobed. The sporangium are on the underside of the leaves in indusium-less sori. Habitat The plant is native to Finland and its fjelds. There it grows best in bare fjeld regions, in the slopes long moistened by the meltwaters from the spots of snow. In the lower alpine regions within easy reach of the birch groves and sometimes in the birch zones, this plant grows at the edges of tall-grass meadows. When it comes to soil, this plant is not too demanding; it is said to even somewhat pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...

Scottish Highlands
The Highlands (; , ) is a historical region of Scotland. Culturally, the Highlands and the Scottish Lowlands, Lowlands diverged from the Late Middle Ages into the modern period, when Scots language, Lowland Scots language replaced Scottish Gaelic throughout most of the Lowlands. The term is also used for the area north and west of the Highland Boundary Fault, although the exact boundaries are not clearly defined, particularly to the east. The Great Glen divides the Grampian Mountains to the southeast from the Northwest Highlands. The Scottish Gaelic name of ' literally means "the place of the Gaels" and traditionally, from a Gaelic-speaking point of view, includes both the Western Isles and the Highlands. The area is very sparsely populated, with many mountain ranges dominating the region, and includes the highest mountain in the British Isles, Ben Nevis. During the 18th and early 19th centuries the population of the Highlands rose to around 300,000, but from c. 1841 and for th ...

Athyrium Filix-femina
''Athyrium filix-femina'', the lady fern or common lady-fern, is a large, feathery species of fern native to temperate Asia, Europe, North Africa, Canada and the US. It is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration. Its common names "lady fern" and "female fern" refer to how its reproductive structures ( sori) are concealed in an inconspicuous – deemed "female" – manner on the frond. Alternatively, it is said to be feminine because of its elegant and graceful appearance. Description ''Athyrium filix-femina'' is now commonly split into three species, typical ''A. filix-femina'', '' A. angustum'' (narrow lady fern) and '' A. asplenioides'' (southern lady fern). ''Athyrium filix-femina'' is cespitose (the fronds arising from a central point as a clump rather than along a rhizome). The deciduous fronds are light yellow-green, long and broad. Overall frond shape tends to be elliptical, with the bottom p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Athyrium Flexile
''Athyrium flexile'', commonly known as Newman's lady-fern or the flexile lady fern, is a taxon of fern which is endemic to Scotland. It has been regarded as a species, but it is considered to be an ecotype of the Alpine lady fern. This fern is pale to yellow green in colour and has elliptic, double pinnate leaves which are deciduous. This ecotype grows more quickly and matures faster than the Alpine lady fern in substrates which have low levels of nutrients and is outcompeted by the Alpine lady fern in other situations. It is an upland variety typically found above on screes made up of siliceous rocks such as quartzite and granite in the Highlands where it is found at only four sites. It is a snow-tolerant species, the snow lie protecting it from frosts. This small, deciduous fern is normally recorded from cool, shaded, north easterly to north westerly facing scree-slopes or where there is scree of large blocks of acidic rocks, particularly in areas where the snow lies late ...

Beinn A' Bhùird
Beinn a' Bhùird is a Munro in the Cairngorms, Cairngorm mountain range of Scotland. In ''Watson'' (1975) the author suggests the mountain should be named ''Beinn Bòrd - table hill'', saying that local Scottish Gaelic speakers pronounced the mountain ''Paing Bòrd'', with some of the older local folk still using ''Painna Bòrd''. The closest 'village' to Beinn a' Bhùird is Braemar, Aberdeenshire and the most common approach by car is through this village. To reach Beinn a' Bhùird by car, the most common approach is by the Linn of Dee road along the south side of the River Dee to the Linn of Dee, looping back along the north bank to the car park at Allanaquoich where camping is permitted. By this route, the distance between Braemar and Allanaquoich is about . In 2006, a glider pilot from Deeside Gliding Club crashed on the hillside, spending 24 hours trapped in his plane until he was located by the RAF.

Ben MacDui
Ben Macdui (, meaning "MacDuff's mountain") is the second-highest Mountains and hills of Scotland, mountain in Scotland and all of the British Isles, after Ben Nevis, and the highest of the Cairngorm Mountains. The summit is above sea level and it is classed as a Munro. Ben Macdui is situated on the southwestern edge of the Cairngorm plateau, overlooking the Lairig Ghru pass to the west, and Loch Etchachan to the east. It lies on the boundary between the Shires of Scotland, historic counties of Aberdeenshire (historic), Aberdeenshire and Banffshire. Before the production of accurate maps of Scotland in the 19th century, it was not known for certain that Ben Nevis was the highest point in Britain, and it was often thought that Ben Macdui might be higher. Following surveys of both peaks in 1846–47, Ben Nevis was confirmed as the higher. The summit of the mountain has a topograph, direction indicator erected in 1925 by the Cairngorm Club of Aberdeen in memory of former presiden ...

Ben Avon
Ben Avon (, 'mountain of the River Avon, Strathspey, Avon') is a mountain in the Cairngorms of Scotland. It is a sprawling mountain with a broad summit plateau dotted with granite Tor (rock formation), tors. One of these marks the summit, called ''Leabaidh an Daimh Bhuidhe'' ("bed of the yellow stag") or ''Stob Easaidh Mòr'', which stands at a height of . It is classified as both a Munro and a Marilyn (hill), Marilyn. From the broad summit plateau ridges lead in almost every direction, allowing access from Glen Avon to the north, from Beinn a' Bhùird to the west and from Gleann an t-Slugain in the south. To the west of the summit lies the massive Cirque, corrie, Slochd Mòr, with its rocky cliffs, and the approaches from the south and west take you close to the corrie rim. The most common ascent route is via the path in the deep glen that separates Ben Avon and Beinn a' Bhùird, or from Beinn a' Bhùird itself. The summit tor itself must be climbed in order to "peak bagging, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
