Helix Caperata
A helix () is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word ''helix'' comes from the Greek word ''ἕλιξ'', "twisted, curved". A "filled-in" helix – for example, a "spiral" (helical) ramp – is a surface called ''helicoid''. Properties and types The ''pitch'' of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A circular helix (i.e. one with constant radius) has constant band curvature and constant torsion. A ''conic helix'', also known as a ''conic spiral'', may be defined as a spiral on a conic surface, with the distance to the apex an expo ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine.

Fauna Europaea
Fauna Europaea is a database of the scientific names and distribution of all living multicellular European land and fresh-water animals. It serves as a standard taxonomic source for animal taxonomy within the Pan-European Species directories Infrastructure (PESI). , Fauna Europaea reported that their database contained 235,708 taxon names and 173,654 species names. Its construction was initially funded by the European Council (2000–2004). The project was co-ordinated by the University of Amsterdam The University of Amsterdam (abbreviated as UvA, nl, Universiteit van Amsterdam) is a public research university located in Amsterdam, Netherlands.

Göttingen State And University Library
The Göttingen State and University Library (german: Niedersächsische Staats- und Universitätsbibliothek Göttingen or SUB Göttingen) is the library for Göttingen University as well as for the Göttingen Academy of Sciences and is the state library for the German State of Lower Saxony. One of the largest German academic libraries, it has numerous national as well as international projects in librarianship and in the provision of research infrastructure services. In the year 2002, the SUB Göttingen won the German Library of the Year (''Bibliothek des Jahres'') award. Its current director is Wolfram Horstmann. The library works under a dispersed system, with six branch libraries located in various academic departments, supplementing the central collection housed in the Central Library (construction completed in 1992) on the main campus and the Historical Library Building in downtown. The Historical Building holds manuscripts, rare books, maps, and a significant history-of-scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AnimalBase
AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature (especially for the late 18th century) can be difficult for researchers who need the old sources for their taxonomic research. AnimalBase data are public domain. The public use of AnimalBase data is not restricted or conditioned.AnimalBase Project Group, 2005-2010. AnimalBase. Early zoological literature online. World wide web electronic publication http://www.animalbase.uni-goettingen.de accessed 30 July 2010. AnimalBase covers all zoological disciplines. In the field of biodiversity informatics A ...

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] |
