Dozmary Pool
Dozmary Pool is a small lake, in the civil parish of Altarnun on Bodmin Moor, Cornwall, UK. It is situated from the sea and lies about north-east of Bodmin and south of Bolventor. It originated in the Holocene, post-glacial period. The outflow from the pool is into Colliford Lake and is therefore one of the sources of the River Fowey. In the past the name has been spelt as Dozmaré and as Dosmery Pool. At the end of the 19th century it was described by Sabine Baring-Gould as abounding in fish and surrounded by numerous remains of the working of flint in the Stone Age. The pool and surrounding area was designated a Site of Special Scientific Interest in 1951 for its Flora and fauna of Cornwall, biological interest and is within the Cornwall Area of Outstanding Natural Beauty, (originally the Bodmin Moor AONB). Wildlife and ecology The oligotrophic pool is important for its Palynology, palynological record (or history) of the Flandrian interglacial, vegetation since the last i ...

Bodmin Moor
Bodmin Moor ( kw, Goon Brenn) is a granite moorland in north-eastern Cornwall, England. It is in size, and dates from the Carboniferous period of geological history. It includes Brown Willy, the highest point in Cornwall, and Rough Tor, a slightly lower peak. Many of Cornwall's rivers have their sources here. It has been inhabited since at least the Neolithic era, when primitive farmers started clearing trees and farming the land. They left their megalithic monuments, hut circles and cairns, and the Bronze Age culture that followed left further cairns, and more stone circles and stone rows. By medieval and modern times, nearly all the forest was gone and livestock rearing predominated. The name Bodmin Moor is relatively recent. An early mention is in the ''Royal Cornwall Gazette'' of 28 November 1812. The upland area was formerly known as Fowey Moor after the River Fowey, which rises within it. Geology Bodmin Moor is one of five granite plutons in Cornwall that make up pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flandrian Interglacial
The Flandrian interglacial or stage is the name given by geologists and archaeologists in the British Isles to the first, and so far only, stage of the Holocene epoch (the present geological period), covering the period from around 12,000 years ago, at the end of the last glacial period to the present day. As such, it is in practice identical in span to the Holocene. The Flandrian began as the relatively short-lived Younger Dryas climate downturn came to an end. This formed the last gasp of the Devensian glaciation, the final stage of the Pleistocene epoch. The Flandrian is traditionally seen as the latest warm interglacial in a series that has been occurring throughout the Quaternary geological period. The first part of the Flandrian, known as the Younger Atlantic, was a period of fairly rapid sea level rise, known as the Flandrian transgression. It is associated with the melting of the Fenno-Scandian, Scottish, Laurentide and Cordilleran glaciers. Fjords were formed durin ...

Eurasian Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small ''Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Coot
The Eurasian coot (''Fulica atra''), also known as the common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand and parts of North Africa. It has a slaty-black body, a glossy black head and a white bill with a white frontal shield. The sexes are similar. Similar looking coot species are found throughout the world, with the largest variety of coot species living in South America. Taxonomy The Eurasian coot was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Fulica atra''. Linnaeus specified the locality as Europe but this is now restricted to Sweden. The binomial name is from Latin: ''Fulica'' means "coot", and ''atra'' means "black". Four subspecies are recognised: * ''F. a. atra'' Linnaeus, 1758 – Europe and north Africa to Japan, India, southeast Asia, Philippines and Borneo * ''F. a. l ...

Anatidae
The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera. (The magpie goose is no longer considered to be part of the Anatidae and is now placed in its own family, Anseranatidae.) They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation. Five species have become extinct since 1600, and many more are threatened with extinction. Description and ecology The ducks, geese, and swans are small- to large-sized birds with a broad and elongated general body plan. Diving species vary from this in being rounder. Extant s ...

Diaptomus
''Diaptomus'' is a genus of copepods with a single eye spot. It is superficially similar in size and appearance to ''Cyclops''. However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in ''Cyclops''. It is a copepod of larger freshwater ponds, lakes and still waters. Species ''Diaptomus'' contains more than 60 species; many species formerly included in ''Diaptomus'' are now in separate genera such as ''Aglaodiaptomus'' and '' Notodiaptomus''. One species, the German endemic ''D. rostripes'', is included on the IUCN Red List as a Data Deficient species. *'' Diaptomus affinis'' Ulyanin, 1875 *'' Diaptomus africanus'' Daday, 1910 *'' Diaptomus alpestris'' (Vogt, 1845) *''Diaptomus angustaensis'' Turner, 1910 *'' Diaptomus armatus'' Herrick, 1882 *'' Diaptomus azureus'' Reid, 1985 *'' Diaptomus barabinensis'' Stepanova, 2008 *''Diaptomus bidens'' Brehm, 1924 *''Dia ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladocera
The Diplostraca or Cladocera, commonly known as water fleas, are a superorder of small crustaceans that feed on microscopic chunks of organic matter (excluding some predatory forms). Over 1000 species have been recognised so far, with many more undescribed. The oldest fossils of diplostracans date to the Jurassic, though their modern morphology suggests that they originated substantially earlier, during the Paleozoic. Some have also adapted to a life in the ocean, the only members of Branchiopoda to do so, even if several anostracans live in hypersaline lakes. Most are long, with a down-turned head with a single median compound eye, and a carapace covering the apparently unsegmented thorax and abdomen. Most species show cyclical parthenogenesis, where asexual reproduction is occasionally supplemented by sexual reproduction, which produces resting eggs that allow the species to survive harsh conditions and disperse to distant habitats. Description They are mostly long, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Eel
The European eel (''Anguilla anguilla'') is a species of eel, a snake-like, catadromous fish. They are normally around and rarely reach more than , but can reach a length of up to in exceptional cases. Eels have been important sources of food both as adults (including jellied eels of East London) and as glass eels. Glass-eel fishing using basket traps has been of significant economic value in many river estuaries on the western seaboard of Europe. While the species' lifespan in the wild has not been determined, captive specimens have lived over 80 years. A specimen known as "the Brantevik Eel" lived for 155 years in the well of a family home in Brantevik, a fishing village in southern Sweden. Conservation status The European eel is a critically endangered species. Since the 1970s, the numbers of eels reaching Europe is thought to have declined by around 90% (possibly even 98%). Contributing factors include overfishing, parasites such as ''Anguillicola crassus'', bar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Carew (antiquary)
Richard Carew (17 July 1555 – 6 November 1620) was a British translator and antiquary. He is best known for his county history, ''Survey of Cornwall'' (1602). Life Carew belonged to a prominent gentry family, and was the eldest son of Thomas Carew: he was born on 17 July 1555 at East Antony, Cornwall. He was educated at Christ Church, Oxford, where he was a contemporary of Sir Philip Sidney and William Camden, and then at the Middle Temple. He made a translation of the first five cantos of Tasso's ''Jerusalem Delivered'' (1594), which was more correct than that of Edward Fairfax. He also translated Juan de la Huarte's ''Examen de Ingenios'', basing his translation on Camillo Camilli's Italian version. (This book is the first systematic attempt to relate physiology with psychology, though based on the medicine of Galen. ) Carew was a member of the Elizabethan Society of Antiquaries, and is particularly known for his ''Survey of Cornwall'' (1602), the second English count ...
