Miguel Vences
Professor Miguel Vences (born 24 April 1969 in Cologne) is a German herpetologist and evolutionary biologist. Much of his research is focused on the reptiles and amphibians of Madagascar. Life The son of Galician philosopher Sergio Vences Fernández (1936–2012), Vences attended the Schiller-Gymnasium Köln from 1979 to 1988, and graduated with the German Abitur. The following year he began to study Biology at the University of Cologne. There he met Frank Glaw, and as undergraduate students they undertook their first excursions to Madagascar. 496 pp. After completing the Vordiplom in 1993, Vences transferred to the University of Bonn and the Museum König, where he completed his Diplom studies. Vences continued his studies there as a PhD student under the supervision of Wolfgang Böhme until 2000. His thesis was on the evolutionary history of true frogs (Ranoidea) and related families in Madagascar. Thereafter, he worked for one year at the National Museum of Natural Histo ...

Cologne
Cologne ( ; german: Köln ; ksh, Kölle ) is the largest city of the German western States of Germany, state of North Rhine-Westphalia (NRW) and the List of cities in Germany by population, fourth-most populous city of Germany with 1.1 million inhabitants in the city proper and 3.6 million people in the Cologne Bonn Region, urban region. Centered on the left bank of the Rhine, left (west) bank of the Rhine, Cologne is about southeast of NRW's state capital Düsseldorf and northwest of Bonn, the former capital of West Germany. The city's medieval Catholic Cologne Cathedral (), the third-tallest church and tallest cathedral in the world, constructed to house the Shrine of the Three Kings, is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne, and Cologne is famous for Eau de Cologne, that has been produced in the city since 1709, and "col ...

Ranoidea
The Ranoidea are a superfamily of frogs in the order Anura. Members of this superfamily are characterised by having the pectoral girdle fused into a single complex unit, having no ribs, and using an axillary grip during amplexus. The larvae have a single spiracle on the left side and complex mouthparts, or in some species, undergo direct development. The taxonomy of these families has been under heavy debate for many years. In recent studies, molecular data has been used to better identify the phylogentic relationships of these frogs, rearranging and introducing new subfamilies to better distinguish between large groups of frogs (Glaw, Vences, 2001). This superfamily contains seventeen different families, each containing at least 2 species (some contain over 300 different species). (See figure 1). Families The families described in this section are based on and Ranixalidae The family of Ranixalidae (leaping frogs) has one genus containing 10 different species. ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Brookesia Micra On A Match Head
''Brookesia'' is a genus of chameleons, endemic to Madagascar, that range from small to very small in size, and are known collectively as leaf chameleons (though this name also commonly is used for species in the genera ''Rieppeleon'' and ''Rhampholeon''). ''Brookesia'' includes species considered to be the world's smallest chameleons, and are also among the smallest reptiles. Members of the genus ''Brookesia'' are largely brown and most are essentially terrestrial. A significant percentage of the species in the genus were only identified to science within the last three decades, and a number of species that still have not received a scientific name are known to exist. Most inhabit very small ranges in areas that are difficult to access, and due to their small size and secretive nature, they have been relatively poorly studied compared to their larger relatives. ''Brookesia'' are abundant in low-disturbance riparian zones and low-disturbance rainforests. ''Brookesia'' are scar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academy Of Sciences Leopoldina
The German National Academy of Sciences Leopoldina (german: Deutsche Akademie der Naturforscher Leopoldina – Nationale Akademie der Wissenschaften), short Leopoldina, is the national academy of Germany, and is located in Halle (Saale). Founded on January 1, 1652, based on academic models in Italy, it was originally named the ''Academia Naturae Curiosorum'' until 1687 when Emperor Leopold I raised it to an academy and named it after himself. It was since known under the German name ''Deutsche Akademie der Naturforscher Leopoldina'' until 2007, when it was declared to be Germany's National Academy of Sciences. History ' The Leopoldina was founded in the imperial city of Schweinfurt on 1 January 1652 under the Latin name sometimes translated into English as "Academy of the Curious as to Nature." It was founded by four local physicians- Johann Laurentius Bausch, the first president of the society, Johann Michael Fehr, Georg Balthasar Metzger, and Georg Balthasar Wohlfarth; and ...

Evolutionary Biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution is based on the theory that all species are related and they gradually change over time. In a population, the genetic variations affect the physical characteristics i.e. phenotypes of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed onto their offspring. Some examples of evolution in species over many generations are the Peppered Moth and Flightless birds. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The importance of studying Evolutionary biology is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
