Synoicum Pulmonaria
''Synoicum pulmonaria'', the tennis ball ascidian or sea-fig, is a species of colonial sea squirt, a tunicate in the family Polyclinidae. It occurs in shallow water in the northeastern Atlantic Ocean, the North Sea and the English Channel, and also, to a lesser extent, in the northwestern Atlantic Ocean. Description ''Synoicum pulmonaria'' is the largest colonial tunicate in the northeastern Atlantic. Young colonies are pear-shaped or club-shaped and are attached by a short stalk. Older colonies are more globular, up to in diameter, and formed by the agglomeration of a number of smaller colonies. The individual zooids are not easy to distinguish, but form groups of seven or eight around a common atrial syphon. The common tunic is tough and cartilaginous, yellowish-brown and transparent. It is usually encrusted with sand and shell fragments. Distribution ''Synoicum pulmonaria'' is a coldwater species of sea squirt and is found in the northeastern Atlantic Ocean as far north as Sv ...

John Ellis (naturalist)
John Ellis ( – 15 October 1776) aka Jean Ellis was a British linen merchant and naturalist. Ellis was the first to have a published written description of the Venus flytrap and its botanical name. Ellis specialised in the study of corals. He was elected a member of the Royal Society in 1754 and in the following year published ''An essay towards the Natural History of the Corallines''. He was awarded the Copley Medal in 1767. He was elected to the American Philosophical Society in 1774. His ''A Natural History of Many Uncommon and Curious Zoophytes'', written with Daniel Solander, was published posthumously in 1776. Ellis was appointed Royal Agent for British West Florida in 1764, and for British Dominica in 1770. He exported many seeds and native plants from North America to England. He corresponded with many botanists, including Carl Linnaeus. Taxonomist Venus's Fly-trap A royal botanist, William Young imported living plants of the Venus flytrap to England. They were the ...

Daniel Solander
Daniel Carlsson Solander or Daniel Charles Solander (19 February 1733 – 13 May 1782) was a Swedish naturalist and an apostle of Carl Linnaeus. Solander was the first university-educated scientist to set foot on Australian soil. Biography Solander was born in Piteå, Norrbotten, Sweden, to Rev. Carl Solander a Lutheran principal, and Magdalena (née Bostadia). Solander enrolled at Uppsala University in July 1750 and initially studied languages, the humanities and law. The professor of botany was the celebrated Carl Linnaeus, who was soon impressed by young Solander's ability and accordingly persuaded his father to let him study natural history. Solander travelled to England in June 1760 to promote the new Linnean system of classification. In February 1763, he began cataloguing the natural history collections of the British Museum, and was elected a Fellow of the Royal Society in June the following year. In 1768, Solander gained leave of absence from the British Museum and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffic ...

Tunicate
A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata (). It is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. They are the only chordates that have lost their myomeric segmentation, with the possible exception of the 'seriation of the gill slits'. Some tunicates live as solitary individuals, but others replicate by budding and become colonies, each unit being known as a zooid. They are marine filter feeders with a water-filled, sac-like body structure and two tubular openings, known as siphons, through which they draw in and expel water. During their respiration and feeding, they take in water through the incurrent (or inhalant) siphon and expel the filtered water through the excurrent (or exhalant) siphon. Most adult tunicates are sessile, immobile and perman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norwegian archipelago in the Arctic Ocean. North of mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a demilitarized zone. The Norwegian Store Norske and the Russian remain the only mining companies in place. Res ...

Normandy
Normandy (; french: link=no, Normandie ; nrf, Normaundie, Nouormandie ; from Old French , plural of ''Normant'', originally from the word for "northman" in several Scandinavian languages) is a geographical and cultural region in Northwestern Europe, roughly coextensive with the historical Duchy of Normandy. Normandy comprises mainland Normandy (a part of France) and the Channel Islands (mostly the British Crown Dependencies). It covers . Its population is 3,499,280. The inhabitants of Normandy are known as Normans, and the region is the historic homeland of the Norman language. Large settlements include Rouen, Caen, Le Havre and Cherbourg. The cultural region of Normandy is roughly similar to the historical Duchy of Normandy, which includes small areas now part of the departments of Mayenne and Sarthe. The Channel Islands (French: ''Îles Anglo-Normandes'') are also historically part of Normandy; they cover and comprise two bailiwicks: Guernsey and Jersey, which are B ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogger Bank
Dogger Bank (Dutch: ''Doggersbank'', German: ''Doggerbank'', Danish: ''Doggerbanke'') is a large sandbank in a shallow area of the North Sea about off the east coast of England. During the last ice age the bank was part of a large landmass connecting mainland Europe and the British Isles, now known as Doggerland. It has long been known by fishermen to be a productive fishing bank; it was named after the ''Dogger (boat), doggers'', medieval Netherlands, Dutch fishing boats especially used for catching cod. At the beginning of the 21st century the area was identified as a potential site for a UK round 3 wind farm, being developed as Dogger Bank Wind Farm. Name The name Dogger Bank was first recorded in the mid-17th century. It is probably derived from the word "dogger (boat), dogger" used for a two-masted boat of the type that trawled for fish in the area in medieval times. The area has similar names in Dutch, German, and Danish. It gives its name to the Dogger sea area use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
