Charles Eric Dawson
Charles Eric "Chuck" Dawson (December 6, 1922 – February 11, 1993) was a Canadian-American ecologist Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ..., ichthyology, ichthyologist, and taxonomy (biology), taxonomist. He held expertise in goby, gobies, flatfishes, and sand stargazers, and was considered "the ultimate authority" on pipefishes in the family Syngnathidae. Life Dawson was born in Vancouver, British Columbia, Canada, but would eventually spend much of his career at the University of Southern Mississippi's Gulf Coast Research Laboratory in Ocean Springs, Mississippi, where he worked early as an administrator, then researcher, and museum curator. Over his long career Dawson wrote 150 publications, on the majority of which he was the sole author. He recognized 52 Syngnat ...

Sand Stargazer
Sand stargazers are blennioids; perciform marine fish of the family Dactyloscopidae. Found in temperate to tropical waters of North and South America; some may also inhabit brackish environments. The giant sand stargazer (''Dactylagnus mundus'') is the largest at 15 cm in length; all other species are under 10 cm. These blennies are named well: sand stargazers have protruding eyes on the top of their heads, fixed in an upward gaze, and may be on stalks. Their large mouths are also upturned. The dorsal fin is long and may or may not be continuous, with seven to 23 spines; the pelvic fins are situated below the throat and possess one spine. The anal fin is equally long and flowing. The mouth is fringed, and like the upper edge of the operculum (the gill cover), this fringe is divided into finger-like structures. The body is greatly elongated, and coloration is generally drab. As their name would suggest, sand stargazers spend most of their time buried in sandy substrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo, Colima, Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a List of national parks of Mexico, national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro (volcano), Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Benedicto Island
San Benedicto, formerly Isla de los Innocentes, is an uninhabited island, and third largest island of the Revillagigedo Islands, located in the Pacific Ocean. It is 4.8 km by 2.4 km in size, with an area 10 km². It is of volcanic origin. It has two prominent peaks. The tallest peak, Bárcena, rises to a height of 332 metres (1,089 feet) near the southern part of the island. It forms a typical volcanic crater. It is located between the remains of two older craters, Herrera in the middle of the island and the Montículo Cinerítico ("Ash Heap") in the southwest. There is no permanent source of freshwater. History The first recorded sighting of San Benedicto was by the Spanish expedition of Hernando de Grijalva on 28 December 1533 that charted it as ''Isla de los Inocentes'' due to this day being the festivity of the Holy Innocents. In November 1542, it was sighted again by the expedition of Ruy López de Villalobos that incorrectly identified it with the ' ...

Socorro Island
Socorro Island ( es, Isla Socorro) is a small volcanic island in the Revillagigedo Islands, a Mexican possession lying off the country's western coast. The size is 16.5 by 11.5 km (10.25 by 7.15 miles), with an area of . It is the largest of the four islands of the Revillagigedo Archipelago. The last eruption was in 1993. Geology The island rises abruptly from the sea to in elevation at its summit. Socorro Island is the emerged summit of a massive, predominately submarine shield volcano. The island is part of the northern Mathematicians Ridge, a mid-ocean ridge that became largely inactive 3.5 million years ago when activity moved to the East Pacific Rise. All four islands along with the many seamounts on the ridge are post-abandonment alkaline volcanoes. Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean. It most recently erupted in late Januaryearly February, 1993, which was a submarine flank eruption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarion Island
Isla Clarión, formerly called Santa Rosa, is the second largest, westernmost and most remote of Mexico's Revillagigedo Islands. The island is located west of Socorro Island and over from the Mexican mainland. It has an area of and three prominent peaks. The westernmost and tallest peak, ''Monte Gallegos'', is high. The central peak is called ''Monte de la Marina'', , and the eastern peak Pico de la Tienda . The coasts are backed by perpendicular cliffs, high, with the exception of the middle part of the southern coast in the vicinity of ''Bahía Azufre'' (Sulphur Bay), which is the location of a small military garrison with a contingent of 9 soldiers. Two small and at least temporarily brackish pools are the only source of fresh water; even these may dry up in summers with little rain. Clarion can only be reached by sea, which from Mexico takes 30 hours. History No signs to indicate prehistoric human activity have ever been found on Clarión Island. It was visited in l ...

Taxa Named By Charles Eric Dawson
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] |
