Richard Greeff
Richard Greeff (14 March 1829, Elberfeld – 30 August 1892, Marburg) was a German zoologist. He studied medicine in Würzburg, Heidelberg and Berlin, receiving his medical doctorate in 1857. Following graduation, he worked as a hospital assistant in Danzig, returning to Elberfeld in 1859 as a physician. Soon afterwards he quit his medical practice in favor of zoological research, subsequently obtaining his habilitation for zoology at the University of Bonn in 1863. In 1871 he succeeded Carl Friedrich Wilhelm Claus as professor of zoology and comparative anatomy at the University of Marburg.ADB:Greeff, Richard @ Allgemeine Deutsche Biographie [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elberfeld
Elberfeld is a municipal subdivision of the German city of Wuppertal; it was an independent town until 1929. History The first official mentioning of the geographic area on the banks of today's Wupper River as "''elverfelde''" was in a document of 1161. Etymologically, ''elver'' is derived from the old Low German word for "river." (See etymology of the name of the German Elbe River; cf. North Germanic ''älv''.) Therefore, the original meaning of "elverfelde" can be understood as "field on the river." Elverfelde received its town charter in 1610. In 1726, Elias Eller and a pastor, Daniel Schleyermacher, founded a Philadelphian society. They later moved to Ronsdorf in the Duchy of Berg, becoming the Zionites, a fringe sect. In 1826 Friedrich Harkort, a famous German industrialist and politician, had a type of suspension railway built as a trial and ran it on the grounds of what is today the tax office at Elberfeld. In fact the railway, the Schwebebahn Wuppertal, was eventu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizopoda
An amoeba (; less commonly spelled ameba or amœba; plural ''am(o)ebas'' or ''am(o)ebae'' ), often called an amoeboid, is a type of Cell (biology), cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopodia, pseudopods. Amoebae do not form a single Taxonomy (biology), taxonomic group; instead, they are found in every major Lineage (evolution), lineage of eukaryote, eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals. Microbiologists often use the terms "amoeboid" and "amoeba" interchangeably for any organism that exhibits amoeboid movement. In older classification systems, most amoebae were placed in the Class (biology), class or subphylum Sarcodina, a grouping of Unicellular organism, single-celled organisms that possess pseudopods or move by protoplasmic flow. However, molecular phylogenetic studies have shown that Sarcodina is not a monophyletic group whose memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

José Vicente Barbosa Du Bocage
José Vicente Barbosa du Bocage (2 May 1823 – 3 November 1907) was a Portuguese zoologist and politician. He was the curator of Zoology at the Museu Nacional de Lisboa in Lisbon. He published numerous works on mammals, birds, and fishes. In the 1880s he became the Minister of the Navy and later the Minister for Foreign Affairs for Portugal. The zoology collection at the Lisbon Museum is called the Bocage Museum in his honor. Du Bocage was born in Funchal, Madeira. He studied at the University of Coimbra from 1839 to 1846. He became lecturer of the chair of Zoology at the Polytechnic School, Lisbon (later the Science Faculty of the University of Lisbon) in 1851, where he taught for more than 30 years. In 1858, he became also the scientific director and curator of Zoology of the Natural History Museum of the Polytechnic School. which was established as a support for the chair. His work at the Museum consisted in acquiring, describing and coordinating collections, many of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese People
The Portuguese people () are a Romance nation and ethnic group indigenous to Portugal who share a common culture, ancestry and language. The Portuguese people's heritage largely derives from the pre-Celts, Proto-Celts (Lusitanians, Conii) and Celts (Gallaecians, Turduli and Celtici), who were Romanized after the conquest of the region by the ancient Romans. A small number of male lineages descend from Germanic tribes who arrived after the Roman period as ruling elites, including the Suebi, Buri, Hasdingi Vandals, Visigoths with the highest incidence occurring in northern and central Portugal. The pastoral Caucasus' Alans left small traces in a few central-southern areas. Finally, the Umayyad conquest of Iberia also left Jewish, Moorish and Saqaliba genetic contributions, particularly in the south of the country. The Roman Republic conquered the Iberian Peninsula during the 2nd and 1st centuries B.C. from the extensive maritime empire of Carthage during the series o ...

Hemidactylus Greeffii
Greeff's giant gecko (''Hemidactylus greeffii'') is a species of gecko, a lizard in the family Gekkonidae. The species is found on islands in the Gulf of Guinea off the east coast of Africa. Etymology The specific name, ''greeffii'', is in honor of German zoologist Richard Greeff, who collected the holotype. Geographic range ''H. greeffii'' is endemic to the island of São Tomé and the associated islet of Ilhéu das Rolas, both in the nation of São Tomé and Príncipe. It does not occur on the island of Príncipe. Reproduction ''H. greeffii'' is oviparous. Taxonomy The species ''H. greeffii'' was described and named by José Vicente Barbosa du Bocage José Vicente Barbosa du Bocage (2 May 1823 – 3 November 1907) was a Portuguese zoologist and politician.

Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick t ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
