Charles Conrad Abbott
Charles Conrad Abbott (June 4, 1843 – July 27, 1919) was an American archaeologist and naturalist. Biography Abbott was born at Trenton, New Jersey, son of Timothy and Susan (Conrad) Abbott; grandson of Joseph and Anne (Rickey) Abbott, and a descendant of John and Anne (Mauleverer) Abbott, settlers, from England, in New Jersey in 1684. He studied medicine at the University of Pennsylvania School of Medicine. During the American Civil War, he served as a surgeon in the Union Army. He received his M.D. degree from University of Pennsylvania in 1865, but never entered into the practice of the profession. In 1876, he announced the discovery, later confirmed by other archaeologists, of traces of human presence in the Delaware River Valley dating from the first or "Kansan" ice age, and inferentially from the pre-glacial period when humans are believed to have entered upon the North American continent. However, today the consensus of archaeologists is that most of Abbott's "Trenton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corixidae
Corixidae is a family of aquatic insects in the order Hemiptera. They are found worldwide in virtually any freshwater habitat and a few species live in saline water. There are about 500 known species worldwide, in 55 genera, including the genus '' Sigara''. Members of the Corixidae are commonly known as water boatmen, a term that is sometimes used in the United Kingdom for ''Notonecta glauca'', an insect of a different family, Notonectidae. ''Corixa punctata'' is the "lesser water boatman". Morphology and ecology Corixidae generally have a long flattened body ranging from long. Many have extremely fine dark brown or black striations marking the wings. They tend to have four long rear legs and two short front ones. The forelegs are covered with hairs and shaped like oars, hence the name "water boatman". Their four hindmost legs have scoop- or oar-shaped tarsi to aid swimming. They also have a triangular head with short, triangular mouthparts. Corixidae dwell in slow rivers and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Insects Described In 1916
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Sigara'' is a genus of water boatmen in the family Corixidae. Some species within this genus are halophiles; for example, occurrences of the genus have been noted in the hypersaline Makgadikgadi Pans in Botswana.C.

Taxa Named By Charles Conrad Abbott
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
