Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, natural history, naturalist and fauna taxonomist. Works Walbaum was from Greifswald. As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Barracuda, Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. Walbaum was one of the first to observe gloves as a preventative against infection in medical surgery. As early as 1767, he used gloves made from sheep intestines for vaginal exams. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection. The museum's collection was, however, destroyed during the Bombing of Lübeck in World War II, Bombing of Lübeck. See also * References 18th-century German ...

Bathurst Inlet
Bathurst Inlet, officially Kiluhiqtuq, is a deep inlet located along the northern coast of the Canadian mainland, at the east end of Coronation Gulf, into which the Burnside and Western rivers empty. The name, or its native equivalent ''Kingoak'' (''Qingaut'', ''nose mountain''), is also used to identify the community of Bathurst Inlet located on the shore. Melville Sound opens into the eastern side of the inlet at Cape Croker, west of the Hurd Islands. Plans for a deep-water port A consortium of seven mining companies sponsored environmental impact studies to construct a deep-water port in Bathurst Inlet. Their plans included building a road connecting the port to their mines. The port would serve vessels of up to 25,000 tonnes. A plan referred to the Nunavut Impact Review Board in May 2004 projected a capacity to moor vessels of up to 50,000 tonnes. In this earlier plan the Bathurst Inlet Road would be an ice road, like that from Yellowknife Yellowknife is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gill Rakers
Gill rakers in fish are bony or cartilaginous processes that project from the branchial arch (gill arch) and are involved with suspension feeding tiny prey. They are not to be confused with the gill filaments that compose the fleshy part of the gill used for gas exchange. Rakers are usually present in two rows, projecting from both the anterior and posterior side of each gill arch. Rakers are widely varied in number, spacing, and form. By preventing food particles from exiting the spaces between the gill arches, they enable the retention of food particles in filter feeders. The structure and spacing of gill rakers in fish determines the size of food particles trapped, and correlates with feeding behavior. Fish with densely spaced, elongated, comb-like gill rakers are efficient at filtering tiny prey, whereas carnivores and omnivores often have more widely spaced gill rakers with secondary projections. Because gill raker characters often vary between closely related taxa, they ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Salish Languages
The Coast Salish languages, also known as the Central Salish languages, are a branch of the Salishan language family.

Geography The Coast Salish languages are spoken around most of the Georgia and Puget Sound Basins, an area that encompasses the sites of the modern-day cities of Vancouver, British Columbia, Seattle, Washington, and others. Archeological evidence indicates that Coast Salish peoples may have inhabited the area as far back as 9000 BCE. What is now Seattle, for example, has been inhabited since the end of the last glacial period (c. 8,000 BCE—10,000 years ago). In the past, the ...
