Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Sweden, Swedish exploration, explorer, oriental studies, orientalist, natural history, naturalist, and an Apostles of Linnaeus, apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, the priest , was serving as a Lutheran clergyman, but the family moved to Sweden in 1741 when the father was appointed to the parish of :sv:Tegelsmora församling, Tegelsmora in Uppland and the Archbishop of Uppsala, archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a Theology, theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Carl Linnaeus, Linnaeus, but appare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaetodon
''Chaetodon'' is a tropical fish genus in the family (biology), family Chaetodontidae. Like their relatives, they are known as "butterflyfish". This genus is by far the largest among the Chaetodontidae, with about 90 living species included here, though most might warrant recognition as distinct genera. Species Extant species There are currently 87 recognized species in this genus: ''Chaetodon sensu stricto'' * ''Chaetodon capistratus'' Linnaeus, 1758 (Foureye butterflyfish) * ''Chaetodon ocellatus'' Marcus Elieser Bloch, Bloch, 1787 (Spotfin butterflyfish) * ''Chaetodon striatus'' Linnaeus, 1758 (Banded butterflyfish) ''C. robustus'' group * ''Chaetodon hoefleri'' Franz Steindachner, Steindachner, 1881 (Four-banded butterflyfish) * ''Chaetodon robustus'' Albert Günther, Günther, 1860 (Three-banded butterflyfish) ''Lepidochaetodon'' group Image:Bep chaetodon punctatofasciatus.jpg, Spotband butterflyfish''Chaetodon (Exornator) punctatofasciatus'' Image:Chaetodon gu ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Subgenus
In biology, a subgenus ( subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all tho ... (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carsten Niebuhr
Carsten Niebuhr, or Karsten Niebuhr (17 March 1733 Cuxhaven, Lüdingworth – 26 April 1815 Meldorf, Dithmarschen), was a German mathematician, Cartography, cartographer, and Geographical exploration, explorer in the service of Denmark-Norway. He is renowned for his participation in the Danish Arabia expedition (1761–1767), Danish Arabia expedition (1761-1767). He was the father of the Danish-German statesman and historian Barthold Georg Niebuhr, who published an account of his father's life in 1817. Early life and education Niebuhr was born in Lüdingworth (now a part of Cuxhaven, Lower Saxony) in what was then Bremen-Verden. His father Barthold Niebuhr (1704-1749) was a successful farmer and owned his own property. Carsten and his sister were educated at home by a local school teacher, then he attended the Latin School in Otterndorf, near Cuxhaven. Originally Niebuhr had intended to become a Surveying, surveyor, but in 1757 he went to the ''Georgia Augusta'' University of G ...

Natural History
Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is called a naturalist or natural historian. Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world, through to European Renaissance naturalists working in near isolation, today's natural history is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. Definitions Before 1900 The meaning of the English term "natural history" (a calque of the Latin ''historia naturalis'') has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also ...

Oriental Studies
Oriental studies is the academic field that studies Near Eastern and Far Eastern societies and cultures, languages, peoples, history and archaeology. In recent years, the subject has often been turned into the newer terms of Middle Eastern studies and Asian studies. Traditional Oriental studies in Europe is today generally focused on the discipline of Islamic studies; the study of China, especially traditional China, is often called Sinology. The study of East Asia in general, especially in the United States, is often called East Asian studies. The European study of the region formerly known as "the Orient" had primarily religious origins, which have remained an important motivation until recent times. That is partly since the Abrahamic religions in Europe (Christianity, Judaism, and Islam) originated in the Middle East and because of the rise of Islam in the 7th century. Consequently, there was much interest in the origin of those faiths and of Western culture in general. Learnin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploration
Exploration is the process of exploring, an activity which has some Expectation (epistemic), expectation of Discovery (observation), discovery. Organised exploration is largely a human activity, but exploratory activity is common to most organisms capable of directed Animal locomotion, locomotion and the ability to learn, and has been described in, amongst others, social insects foraging behaviour, where feedback from returning individuals affects the activity of other members of the group. Types Geographical Geographical exploration, sometimes considered the default meaning for the more general term exploration, is the practice of discovering lands and regions of the planet Earth remote or relatively inaccessible from the origin of the explorer. The surface of the Earth not covered by water has been relatively comprehensively explored, as access is generally relatively straightforward, but underwater and subterranean areas are far less known, and even at the surface, much is ...

Swedish-speaking Population Of Finland
The Swedish-speaking population of Finland (whose members are called by many names—see below; ; ) is a linguistic minority in Finland. They maintain a strong identity and are seen either as a separate cultural, ethnic or linguistic group or, occasionally, a distinct nationality. They speak Finland Swedish, which encompasses both a standard language and distinct dialects that are mutually intelligible with the dialects spoken in Sweden and, to a lesser extent, other Scandinavian languages. According to Statistics Finland, Swedish is the mother tongue of about 260,000 people in mainland Finland and of about 26,000 people in Åland, a self-governing archipelago off the west coast of Finland, where Swedish is the sole official language. Swedish-speakers comprise 5% of the total Finnish population or about 4.9% without Åland. The proportion has been steadily diminishing since the early 19th century, when Swedish was the mother tongue of approximately 15% of the population a ...

Socotra
Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea, it lies near major shipping routes. Socotra is the largest of the six islands in the Socotra archipelago as it comprises around 95% of the landmass of the archipelago. It lies south of the Arabian Peninsula and east of the Horn of Africa. The inhabitants of the island are called Soqotri people, Socotrans, and they speak Arabic and Soqotri language, Soqotri. Socotra is home to a high number of unique species that are endemism, endemic to it. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures in length and across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site. The island is under the control of the Southern Transitional Council (STC), a United Arab Emirates-backed, pro-Presidential Leadership Co ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfort on the Oder with a treatise on skin disorders. He then became a ...
