Swan Mussel
The swan mussel, ''Anodonta cygnea'', is a large species of freshwater mussel, an aquatic bivalve mollusc in the family Unionidae, the river mussels. Because of its morphological variability and its wide range of distribution, there are over 500 synonyms for this species. Shell description The shell is thin but large (approximately 10 to 20 cm) and rather flat, even at the umbo. The shell color is often pale greenish or brownish. It differs from ''Anodonta anatina'' in being larger shell with straighter, more parallel dorsal and ventral margins; the growth lines of the inner, oldest part of the shell are finer and shallower, and reach the margin. Distribution Its native distribution is European-Siberian. The geographical distribution of this species is from the British Isles east to Siberia, and south into northern Africa. * Croatia * Czech Republic – in Bohemia, in Moravia, vulnerable (VU); Czech code, Decree for implementation, No. 395/1992 Sb.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANEMOON
The ANEMOON Foundation, in Dutch Stichting ANEMOON, is a foundation dedicated to the study of marine life in the Netherlands. "Anemoon" is a Dutch word that means anemone, as in sea anemone, a marine organism portrayed in the logo of the foundation, although here the word is used as an acronym An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as ..., based on the Dutch words "ANalyse Educatie Marien Oecologisch ONderzoek", meaning "analysis, education and marine ecological research". ANEMOON was founded in 1993 to focus on encouraging and supporting research on marine fauna and flora that is carried out by volunteers, i.e. citizen scientists. ANEMOON is one of ten non-governmental data-managing organizations (PGOs, Particuliere Gegevensbeherende Organisaties) which compile data on the fau ...

Bundesartenschutzverordnung
The Federal Species Protection Regulations, first adopted on 19 December 1986, is a set of federal regulations in Germany. These regulations protect wild plants and animals. They are the implementing rules promulgated by the government to give force to the Federal Nature Conservation Act which passed on 1 January 1977. With the passage of new legislation, it became necessary to update the regulations. The current version of these laws dates from 16 February 2005. Annex 1 of these regulations lists the protected plants and animals. The protected species should not be confused with the Red Lists of animal and plant species in danger of extinction Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and ....

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
