Burmeister's Porpoise
Burmeister's porpoise (''Phocoena spinipinnis'') is a species of porpoise endemic to the coast of South America. It was first described by Hermann Burmeister, for whom the species is named, in 1865. Population and distribution While Burmeister's porpoise seems to be relatively common in its range, little work has been done to survey the species. The total population is at least in the tens of thousands. Its range appears to be continuous in coastal waters from northern Peru in the Pacific Ocean round Tierra del Fuego and up to southern Brazil in the Atlantic Ocean. Burmeister's porpoises frequent inshore bays, channels, and fjords, but individuals have been spotted as far as from the shore and in the freshwater Valdivia River in southern Chile. Though normally found in continental shelf waters, they have been found as deep as Description Most photographs of Burmeister's porpoises are taken of dead specimens and show the animal to be coloured black. This phenomenon gave rise t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Burmeister
Karl Hermann Konrad Burmeister (also known as Carlos Germán Conrado Burmeister) (15 January 1807 – 2 May 1892) was a German Argentine zoologist, entomologist, herpetologist, botany, botanist, and coleopterologist. He served as a professor at the Martin Luther University Halle-Wittenberg, University of Halle, headed the museum there and published the ''Handbuch der Entomologie'' (1832–1855) before moving to Argentina where he worked until his death. Career Burmeister was born in Stralsund, where his father was a customs officer. He studied medicine at University of Greifswald, Greifswald (1825–1827) and Halle (Saale), Halle (1827–1829), and in 1830 went to Humboldt University of Berlin, Berlin to qualify himself to be a teacher of natural history. His dissertation was titled ''De insectorum systemate naturali'' and graduated as a doctor of medicine on November 4, 1829 and then received a doctor of philosophy on December 19 in the same year. He then joined for military ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uruguay
Uruguay, officially the Oriental Republic of Uruguay, is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast, while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately . It has a population of almost 3.5 million people, of whom nearly 2 million live in Montevideo metropolitan area, the metropolitan area of its capital and List of cities in Uruguay, largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter gatherer, hunter gatherers 13,000 years ago. The first European explorer to reach the region was Juan Díaz de Solís in 1516, but the area was colonized later than its neighbors. At the time of Spanish colonization of the Americas, European arrival, the Charrúa were the predominant tribe, alongside other groups such as the Guaraní people ...

Mammals Of Brazil
Brazil has the largest mammal diversity in the world, with around 711 described species and more likely to be discovered. According to the International Union for Conservation of Nature, 66 of these species are endangered, and 40% of the threatened taxa belong to the primate group. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of least concern categories: Infraclass: Metatheria Order: Didelphimorphia * Family: Caluromyidae ** Genus: '' Caluromys'' *** Brown-eared woolly opossum, ''C. lanatus'' *** Bare-tailed woolly opossum, ''C. philander'' * Family: Didelphidae ** Genus: ''Caluromysiops'' *** Black-shouldered opossum, ''Caluromysiops irrupta'' ** Genus: ''Glironia'' *** Bushy-tailed opossum, ''Glironia venusta'' ** Genus: '' Chironectes'' *** Wat ...

Mammals Of Argentina
This is a list of the native mammal species recorded in Argentina. As of January 2020, the list contains 402 mammal species from Argentina, of which one is extinct, seven are critically endangered, seventeen are endangered, sixteen are vulnerable, and thirty are near threatened.

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many scientific classification, phyla, family (biology), families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment (biophysical), environment rather than on taxonomy (biology), taxonomy. A large proportion of all life, life on Earth lives in the ocean. The exact size of this "large proportion" is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world, covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean.

List Of Cetaceans
Cetacea is an infraorder that comprises the 94 species of whales, dolphins, and porpoises. It is divided into toothed whales (Odontoceti) and baleen whales (Mysticeti), which diverged from each other in the Eocene some 50 mya (unit), million years ago (mya). Cetaceans are descended from land-dwelling hoofed mammals, and the now extinct archaeocetes represent the several transitional phases from terrestrial to completely aquatic. Historically, cetaceans were thought to have descended from the wolf-like Mesonychia, mesonychians, but cladistic analyses confirm their placement with even-toed ungulates in the order Cetartiodactyla. Whale populations were drastically reduced in the 20th century from intensive whaling, which led to a moratorium on hunting by the International Whaling Commission in 1982. Smaller cetaceans are at risk of accidentally getting caught by fishing vessels using, namely, seine fishing, drift netting, or gill netting operations. Conventions The following is ...

Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within t ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...
