Black Duck Joint Venture
The Black Duck Joint Venture is a conservation partnership established in 1989 to stabilize and restore the population of the American black duck (''Anas rubripes''). It consists of government and non-governmental agencies and organizations in Canada and the United States. Its geographical scope is the Canadian provinces of Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador, and the 23 U.S. states in the Atlantic and Mississippi Flyways. It was the first of the three species joint ventures operating within the North American Waterfowl Management Plan to be established. Structure and funding The joint venture has a management board consisting of eleven members "with representation from Canadian and U.S. wildlife agencies". It is advised by a technical board composed of waterfowl biologists, which is responsible for project implementation and progress evaluation. Members are also organized into working groups representing each program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation (ethic)
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of t ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

CRC Press
The CRC Press, LLC is an American publishing group that specializes in producing technical books. Many of their books relate to engineering, science and mathematics. Their scope also includes books on business, forensics and information technology. CRC Press is now a division of Taylor & Francis, itself a subsidiary of Informa. History The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. The company gradually expanded to include sales of laboratory equipment to chemists. In 1913 the CRC offered a short (116-page) manual called the ''Rubber Handbook'' as an incentive for any purchase of a dozen aprons. Since then the ''Rubber Handbook'' has evolved into the CRC's flagship book, the '' CRC Handbook of Chemistry and Physics''. In 1964, Chemical Rubber decided to focus on its publishing ventures ...

Montezuma National Wildlife Refuge
Montezuma National Wildlife Refuge is a wildlife preserve operated by the United States Fish and Wildlife Service, encompassing part of the Montezuma Swamp at the north end of Cayuga Lake. The preserve is composed of swamps, pools and channels and is a stopping point for migratory birds. The refuge lies between the cities of Rochester and Syracuse, New York ( east of Seneca Falls, and west of Auburn), including parts of Seneca, Cayuga, and Wayne counties. Most of the refuge lies in the Town of Tyre, in the northeast corner of Seneca County. The Montezuma Marshes were designated a National Natural Landmark in May 1973; the citation notes that "A small, 100-acre area within the site is one of the best examples of undisturbed swamp woodlands in New York or New England." The New York Northern Montezuma Wildlife Management Area borders the national wildlife refuge and protects additional parts of the Montezuma Swamp. A significant spot along the Atlantic Flyway, the Refuge pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Habitat Joint Venture
The Eastern Habitat Joint Venture is a partnership established on 15 November 1989 between governments, organizations, and conservation groups in eastern Canada to protect and enhance wetlands important to migratory birds, under the auspices of the North American Waterfowl Management Plan. The founding partners were the six easternmost provinces (Ontario, Quebec, Newfoundland and Labrador, Nova Scotia, New Brunswick and Prince Edward Island), the Canadian Wildlife Service (a branch of Environment and Climate Change Canada), Ducks Unlimited Canada, and Wildlife Habitat Canada. As a signatory, each province was expected to develop and implement its own program. Objectives The initial goals of the plan at founding were to conserve approximately 18,000 km² of wetlands in the eastern provinces by 2004. These wetlands are important to waterfowl and other migratory birds that use the Atlantic Flyway. Programs Ontario In Ontario, the program is administered by the Canadian Wildlife Ser ...

Atlantic Canada
Atlantic Canada, also called the Atlantic provinces (french: provinces de l'Atlantique), is the region of Eastern Canada comprising the provinces located on the Atlantic coast, excluding Quebec. The four provinces are New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island. As of 2021, the landmass of the four Atlantic provinces was approximately 488,000 km2, and had a population of over 2.4 million people. The provinces combined had an approximate GDP of $121.888 billion in 2011. The term ''Atlantic Canada'' was popularized following the admission of Newfoundland as a Canadian province in 1949. History The first premier of Newfoundland, Joey Smallwood, coined the term "Atlantic Canada" when Newfoundland joined Canada in 1949. He believed that it would have been presumptuous for Newfoundland to assume that it could include itself within the existing term "Maritime provinces," used to describe the cultural similarities shared by New Brunswick, Prince ...
