Erich Rutschke
Erich Rutschke (26 May 1926 – 12 February 1999) was a German ornithologist and conservationist who specialized in wetland birds and their biology. Rutschke was responsible for making East Germany a signatory of the Ramsar Convention. Rustchke was born in Neu-Golm, Bad Saarow in Germany. During the war he served as a paratrooper and was wounded. He became a teacher in 1946. He was interested in birds from childhood but took an interest in ornithology as a career after meeting Erwin Stresemann. He received a PhD for his work on water resistance in plumage in 1958 which included studies on the feathers of penguins. He became a professor of animal physiology at Potsdam and later became a professor at the Pedagogical Highschool in 1991. He took an interest in waterbirds and the conservation of their habitats establishing a waterbird research centre in East Germany in 1967 and conducting bird censuses. He conducted research on greylag geese and their migration. Rutschke helped make th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greylag Geese
The greylag goose or graylag goose (''Anser anser'') is a species of large goose in the waterfowl family Anatidae and the type species of the genus ''Anser (bird), Anser''. It has mottled and barred grey and white plumage and an orange beak and pink legs. A large bird, it measures between in length, with an average weight of . Its distribution is widespread, with birds from the north of its range in Europe and Asia Bird migration, migrating southwards to spend the winter in warmer places. It is the type species of the genus ''Anser (bird), Anser'' and is the ancestor of most breeds of domestic goose, having been domesticated at least as early as 1360 BC. The genus name is from ''anser'', the Latin for "goose". Greylag geese travel to their northerly breeding grounds in spring, nesting on moorlands, in marshes, around lakes and on coastal islands. They normally mate for life and nest on the ground among vegetation. A clutch of three to five eggs is laid; the female incubate ...

Academic Staff Of The University Of Potsdam
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cormorant
Phalacrocoracidae is a family of approximately 40 species of aquatic birds commonly known as cormorants and shags. Several different classifications of the family have been proposed, but in 2021 the IOC adopted a consensus taxonomy of seven genera. The great cormorant (''Phalacrocorax carbo'') and the common shag (''Gulosus aristotelis'') are the only two species of the family commonly encountered in Britain and Ireland and "cormorant" and "shag" appellations have been later assigned to different species in the family somewhat haphazardly. Cormorants and shags are medium-to-large birds, with body weight in the range of and wing span of . The majority of species have dark feathers. The bill is long, thin and hooked. Their feet have webbing between all four toes. All species are fish-eaters, catching the prey by diving from the surface. They are excellent divers, and under water they propel themselves with their feet with help from their wings; some cormorant species have been ...

Peter Scott
Sir Peter Markham Scott, (14 September 1909 – 29 August 1989) was a British ornithologist, conservationist, painter, naval officer, broadcaster and sportsman. The only child of Antarctic explorer Robert Falcon Scott, he took an interest in observing and shooting wildfowl at a young age and later took to their breeding. He established the Wildfowl & Wetlands Trust in Slimbridge in 1946 and helped found the World Wide Fund for Nature, the logo of which he designed. He was a yachting enthusiast from an early age and took up gliding in mid-life. He was part of the UK team for the 1936 Summer Olympics and won a bronze medal in sailing. He was knighted in 1973 for his work in conservation of wild animals and was also a recipient of the WWF Gold Medal and the J. Paul Getty Prize. Early life Scott was born in London at 174, Buckingham Palace Road, the only child of Antarctic explorer Robert Falcon Scott and sculptor Kathleen Bruce.

Stasi
The Ministry for State Security, commonly known as the (),An abbreviation of . was the Intelligence agency, state security service of the East Germany from 1950 to 1990. The Stasi's function was similar to the KGB, serving as a means of maintaining state authority, i.e., the "Sword and Shield of the Party" (). This was accomplished primarily through the use of a network of civilian informants. This organization contributed to the arrest of approximately 250,000 people in East Germany. The Stasi also conducted espionage and other clandestine operations abroad through its subordinate foreign intelligence service, the Main Directorate for Reconnaissance, Office of Enlightenment, or Head Office A (german: Hauptverwaltung Aufklärung). They also maintained contacts and occasionally cooperated with West German terrorists. The Stasi was headquartered in East Berlin, with an extensive complex in Lichtenberg (locality), Berlin-Lichtenberg and several smaller facilities throughout the c ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservationist (biology)
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management. The conservation ethic is based on the findings of conservation biology. Origins The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke, Sir Otto Frankel, Thomas Lovejoy, and Jared Diamond. The meeting was prompted due to concern over tropical deforestation, disappearin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine.
