Tursiops Erebennus
Tamanend's bottlenose dolphin (''Tursiops erebennus'') is a species of bottlenose dolphin that inhabits coastal waters in the eastern United States. This species was previously considered a nearshore variant of the common bottlenose dolphin ''Tursiops truncatus''. Taxonomy ''Tursiops erebennus'' was first described by Edward Drinker Cope as ''Delphinus erebennus'' in 1865. The type specimen was collected from a fisherman's seine net at the Red Bank community in West Deptford Township, New Jersey. Cope identified various physical differences between ''T. erebennus'' and ''T. truncatus'' (then known as ''Delphinus tursio''), including a smaller size, fewer vertebrae, and fewer ribs in ''T. erebennus''. However, ''T. erebennus'' was subsequently synonymized with ''T. truncatus''. Future studies and stock assessments instead recognized dolphins in the region as belonging to two ''T. truncatus'' ecotypes: a nearshore coastal type and an offshore type. Genetic analyses suggested that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamanend
Tamanend ("the Affable"; ), historically also known as Taminent, Tammany, Saint Tammany or King Tammany, was the Chief of Chiefs and Chief of the Turtle Clan of the Lenni-Lenape nation in the Delaware Valley signing the founding peace treaty with William Penn. Also called a "Patron Saint of America", Tamanend represented peace and amity, and became a popular figure in 18th-century America, especially in Philadelphia. A Tammany society founded in Philadelphia holds an annual Tammany festival. Tammany societies (Tammany Hall being the most well-known and influential) were established across the United States after the American Revolutionary War, and Tammany assumed mythic status as an icon for the peaceful politics of negotiation. Life and legend Tamanend reputedly took part in a meeting between the leaders of the Lenni-Lenape nation, and the leaders of the Pennsylvania colony held under a large elm tree at Shakamaxon in the early 1680s. William Penn and Tamanend continued to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Mexico
The Gulf of Mexico () is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the southeast by Cuba. The coastal areas along the Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are occasionally referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific coasts), but more often as "the Gulf Coast". The Gulf of Mexico took shape about 300 million years ago (mya) as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is about wide. Its floor consists of sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Straits of Florida between the ...

Estuaries
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphology, geomorphological features or to water-circulation patterns. They can have many different names, s ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Nanticoke Lenni-Lenape
The Nanticoke Lenni-Lenape Tribal Nation (also known as the Nanticoke Lenni Lenape Inc. or the Nanticoke Lenape) is a state-recognized tribe and 501(c)(3) nonprofit organization. They represent Nanticoke Indian Tribe, Nanticoke of the Delmarva Peninsula and the Lenape of southern New Jersey and northern Delaware. The state of New Jersey recognizes them, and they have maintained elected governments since the 1970s. They are not a federally recognized tribe. The tribe is made up of descendants of Algonquian-speaking Nanticoke and Lenape peoples who remained in or returned to their ancient homeland at Delaware Bay. Many of their relatives suffered removals and forced migrations to the central United States and Canada. The Nanticoke and Lenni-Lenape peoples were among the first in what is now the United States to resist European encroachment upon their lands, among the first to sign treaties in an attempt to create a peaceful coexistence, and were among the first to be forced onto re ...

Lenni-Lenape
The Lenape (, , ; ), also called the Lenni Lenape and Delaware people, are an Indigenous people of the Northeastern Woodlands, who live in the United States and Canada. The Lenape's historical territory included present-day northeastern Delaware, all of New Jersey, the eastern Pennsylvania regions of the Lehigh Valley and Northeastern Pennsylvania, and New York Bay, western Long Island, and the lower Hudson Valley in New York state. Today communities are based in Oklahoma, Wisconsin, and Ontario. During the last decades of the 18th century, European settlers and the effects of the American Revolutionary War displaced most Lenape from their homelands and pushed them north and west. In the 1860s, under the Indian removal policy, the U.S. federal government relocated most Lenape remaining in the Eastern United States to the Indian Territory and surrounding regions. The largest Lenape communities are currently the Delaware Nation and Delaware Tribe of Indians in Oklahoma, the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erebus
In Greek mythology, Erebus (; ), or Erebos, is the personification of darkness. In Hesiod's ''Theogony'', he is the offspring of Chaos, and the father of Aether and Hemera (Day) by Nyx (Night); in other Greek cosmogonies, he is the father of Aether, Eros, and Metis, or the first ruler of the gods. In genealogies given by Roman authors, he begets a large progeny of personifications upon Nox (the Roman equivalent of Nyx), while in an Orphic theogony, he is the offspring of Chronos (Time). The name "Erebus" is also used to refer either to the darkness of the Underworld, the Underworld itself, or the region through which souls pass to reach Hades, and can sometimes be used as a synonym for Tartarus or Hades. Etymology The meaning of the word ''Érebos'' ( Ἔρεβος) is "darkness" or "gloom", referring to that of the Underworld. It derives from the Proto-Indo-European ' ("darkness"), and is cognate with the Sanskrit '' rájas'' ("dark (lower) air, dust"), the Armenian '' er ...

Édouard Louis Trouessart
Édouard Louis Trouessart (25 August 1842 – 30 June 1927) was a French zoologist born in Angers. He studied military medicine in Strasbourg, but was forced to leave school due to serious health problems. In 1864 he started work as ''préparateur de physique'' at the Faculty of Poitiers, and in the process, dedicated his time and energies to natural history. He also resumed his studies in medicine, earning a medical doctorate in 1870. During the Franco-Prussian War, he served in the French army. Later, he was employed at the hospital in Villevêque. From 1882 to 1884, he was director at the Museum of Angers, and in the meantime taught classes in natural history at the high school in Angers. In 1885 he relocated to Paris, where he worked with Alphonse Milne-Edwards (1835-1900). After the death of Emile Oustalet (1844-1905), he attained the chair of zoology (mammals and birds), a position he maintained until 1926.

Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
