List Of Endemic Species Of The British Isles
The British Isles have few endemic species due to past frequent glaciations and because of the proximity to Continental Europe and former land bridges which enabled species to re-colonise the islands from the continent following glaciations. Most endemic species to the British Isles are considered to be subspecies of a larger species, with mutations or adaptations slightly changing the species in the islands or in certain localities. British conservationists often describe this as a "wiped clean effect" with repeated glaciations forcing many species out of the modern area of the islands to more southern latitudes in Europe and perhaps even driving some species extinct. Some species which were present in Britain before past glaciations, often during periods with a warmer climate than now failed to return after the Last Glacial Maximum. Amongst these are ''Rhododendron ponticum'' and rabbits, now considered invasive and non-native. A species is only deemed native if it reached ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Earthstar Fungus
Geastrales is an order of gasterocarpic basidiomycetes (fungi) that are related to Cantharellales. The order contains the single family Geastraceae, commonly known as "earthstars", which older classifications had placed in Lycoperdales, or Phallales. Approximately 64 species are classified in this family, divided among eight genera, including the ''Geastrum'', '' Myriostoma'' and '' Sphaerobolus''. The ''Sphaerobolus'' are known as "shotgun fungus" or "cannonball fungus". They colonize wood-based mulches and may throw black, sticky, spore-containing globs onto nearby surfaces. The fruiting bodies of several earthstars are hygroscopic: in dry weather the "petals" will dry and curl up around the soft spore sac, protecting it. In this state, often the whole fungus becomes detached from the ground and may roll around like a tumbleweed. Once mature, their exoperidium splits into a variable number of rays, which give Geastrum their visible star shape. The exoperidial rays are t ...

Limonium
''Limonium'' is a genus of 120 flowering plant species. Members are also known as sea-lavender, statice, caspia or marsh-rosemary. Despite their common names, species are not related to the lavenders or to rosemary. They are instead in Plumbaginaceae, the plumbago or leadwort family. The generic name is from the Latin ', used by Pliny for a wild plant and is ultimately derived from the Ancient Greek ' (, ‘meadow’). Distribution The genus has a subcosmopolitan distribution in Europe, Asia, Africa, Australia and North America. By far the greatest diversity (over 100 species) is in the area stretching from the Canary Islands east through the Mediterranean region to central Asia; for comparison, North America only has three native ''Limonium'' species. Description Sea-lavenders normally grow as herbaceous perennial plants, growing 10–70 cm tall from a rhizome; a few (mainly from the Canary Islands) are woody shrubs up to 2 metres tall. Many species flourish in saline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphrasia
''Euphrasia'', or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae (formerly included in the Scrophulariaceae), with a cosmopolitan distribution. They are semi-parasitic on grasses and other plants. The common name refers to the plant's use in treating eye infections. Many species are found in alpine or sub-alpine meadows where snow is common. Flowers usually are borne terminally, are zygomorphic, and have a lower petal shaped like a lip. The most common flower colours are purple, blue-white, and violet. Some species have yellow markings on the lower petal to act as a guide to pollinating insects. Alternative names, mainly in herbalism, are ''Augentrostkraut, Euphrasiae herba, Herba Euphrasiae'' and ''Herbe d'Euphraise''. Use in herbalism and medicine The plant was known to classical herbalists, but then was not referred to until mentioned again in 1305. Nicholas Culpeper assigned it to the Zodiac sign Leo, claiming that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microspecies
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most case ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scottish Primrose (Primula Scotica) - Geograph
''Primula scotica'', commonly known as Scottish primrose, is a species of flowering plant in the family, Primulaceae, the primroses and their relatives. It was discovered by James Smith, and is endemic to the north coast of Scotland. Description ''Primula scotica'' is a low biennial plant with mealy stems and leaves.

Peak District
The Peak District is an upland area in England at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It includes the Dark Peak, where moorland is found and the geology is dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west sides; the White Peak covers central and southern tracts. The historic Peak District extends beyond the National Park, which excludes major towns, quarries and industrial areas. It became the first of the national parks of England and Wales in 1951. Nearby Manchester, Stoke-on-Trent, Derby and Sheffield send millions of visitors – some 20 million live within an hour's ride. Inhabited from the Mesolithic era, it shows evidence of the Neolithic, Bronze and Iron Ages. Settled by the Romans and Anglo-Saxons, it remained largely agricultural; mining arose in the Middle Ages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thamnobryum Angustifolium
''Thamnobryum angustifolium'', the Derbyshire feathermoss, is a species of moss in the Neckeraceae family. It is endemic to Derbyshire, England, being restricted to a single SSSI, where the main colony covers about of a single rock face, with small subsidiary colonies nearby. Threats include disturbance from cavers and climbers, collection by bryologists, pollution of the spring in which it grows, and desiccation during periods of drought. Its natural habitat is river A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of ...s.
