Mascarene Teal
The Mascarene teal (''Anas theodori''), also known as Sauzier's teal and Mauritian duck, is an extinct dabbling duck that formerly occurred on the islands of Mauritius and Réunion. Taxonomy The reports of Bernardin and (1710) Boucher are puzzling insofar as that they mention both geese, ''sarcelles'' (teals, or ducks, which is this species) as well as ''canards'' (ducks, larger than ''sarcelles'') as occurring or having occurred on Réunion. It is possible that a carpometacarpus bone apparently of an ''Aythya'' diving duck is referrable to these ''canards''. If so, these birds were probably related to the Madagascar pochard, of which only small numbers are known to remain. Earlier, it was proposed that Meller's duck, also from Madagascar, is the closest living relative of ''A. theodori'', but as more remains of the latter were unearthed this appears far less likely. Apart from a few, brief descriptions, not much is known about the bird in life, but its habits probably did no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Superspecies
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant varieties), which may be a complex ranking but it is not a species complex. In most cases, a species complex is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Animals Of Mauritius
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anas
''Anas'' is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name ''Anas'' is the Latin for "duck". Systematics The genus ''Anas'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. ''Anas'' is the Latin word for a duck. The genus formerly included additional species. In 2009 a large molecular phylogenetic study was published that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae. The results confirmed some of the conclusions of earlier smaller studies and indicated that the genus as then defined was non-monophyletic. Based on the results of this study, ''Anas'' was split into four proposed monophyletic genera with five sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transactions Of The Zoological Society
The ''Journal of Zoology'' is a scientific journal concerning zoology, the study of animals. It was founded in 1830 by the Zoological Society of London and is published by Wiley-Blackwell. It carries original research papers, which are targeted towards general readers. Some of the articles are available via open access, depending on the author's wishes. According to the ''Journal Citation Reports'', the journal has a 2020 impact factor of 2.322, ranking it 36th out of 175 journals in the category "Zoology". From around 1833, it was known as the ''Proceedings of the Zoological Society of London'' (). From 1965 to 1984, it was known as the ''Journal of Zoology: Proceedings of the Zoological Society of London'' ().

Père Bernardin
A name suffix in the Western English-language naming tradition, follows a person's surname (last name) and provides additional information about the person. Post-nominal letters indicate that the individual holds a position, educational degree, accreditation, office, or honor (e.g. "PhD", "CCNA", "OBE"). Other examples include generational designations like "Sr." and "Jr." and "I", "II", "III", etc. Post-nominal letters Academic Academic suffixes indicate the degree earned at a college or university. These include bachelor's degrees (AB, BA, BS, BE, BFA, BTech, LLB, BSc, etc.), master's degrees ( MA, MS, MFA, LLM, MLA, MBA, MSc, MEng etc.), professional doctorates ( JD, MD, DO, PharmD, DMin, etc.), and academic doctorates (PhD, EdD, DPhil, DBA, LLD, EngD, etc.) In the case of doctorates, normally either the prefix (e.g. "Dr" or "Atty") or the suffix (see examples above) is used, but not both. In the United States, the suffix is the preferred format (thus allowing diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Feuilley
Jean Feuilley was a pilot engineer and cartographer who was sent to Réunion by the French East India Company to investigate the possibility of agricultural and marine exploitation. He arrived in the island in 1704 and the following year returned to France. His "Mission à l’île Bourbon du sieur Feuilley en 1704" (published 1705) contains among other things descriptions of now-extinct bird species, like the Réunion kestrel and the Réunion ibis The Réunion ibis or Réunion sacred ibis (''Threskiornis solitarius'') is an list of extinct birds, extinct species of ibis that was endemic to the volcanic island of Réunion in the Indian Ocean.

Roelof Deodati
Roelof Diodati (Dordrecht, 28 July 1658 – Batavia, 10 March 1723) was a governor of Dutch Mauritius in the late 17th century. Life Diodati was of Swiss-Italian descent. His grandfather was Jean Diodati, a theologian, who translated the Bible into Italian. His father, born in Geneva, became a pastor of the Walloon church in Leiden in 1651. It is not obvious Rodolfo Diodati was one of a twin. Both brothers took service at the Dutch East India Company. He became an accountant at the Cape in 1686 and then a merchant. He was appointed as governor of Mauritius from 1692 to 1703. In 1693 he had to deal with François Leguat. In 1695, a big hurricane devastated the island, several of the Burghers lost all their crops, and many left the island. Diodati seems to have been appointed in Suratte. Then he shifted to Batavia and he became a merchant and accountant on 4 January 1707. In 1709 he married Catharina Zaaiman, born on Dutch Mauritius. Her grandmother was Eva, a Khoikhoi inter ...

Alopochen Kervazoi And Anas Theodori
''Alopochen'' is a genus of the bird family Anatidae, part of the subfamily Tadorninae along with the shelducks. It contains one extant species, the Egyptian goose (''Alopochen aegyptiaca''), and three which became extinct in the last 1,000 years or so. The Egyptian goose is native to mainland Africa, and the recently extinct species are from Madagascar and the Mascarene Islands. mtDNA cytochrome ''b'' sequence data suggest that the relationships of ''Alopochen'' to ''Tadorna'' need further investigation. Species * Egyptian goose (''Alopochen aegyptiaca'') The extinct species of the genus are: * †Malagasy shelduck or Madagascar shelduck (''Alopochen sirabensis'') (Andrews 1897) (may be a subspecies of ''A. mauritiana'') – Madagascar, Late Pleistocene: see Late Quaternary prehistoric birds * †Mauritius sheldgoose (''Alopochen mauritiana'') (Newton & Gadow 1893) – Mauritius, late 1690s * †Réunion sheldgoose or Kervazo's Egyptian goose (''Alopochen kervazoi'') (Cowles ...
