International Biological Programme
The International Biological Program (IBP) was an effort between 1964 and 1974 to coordinate large-scale ecological and environmental studies. Organized in the wake of the successful International Geophysical Year (IGY) of 1957-1958, the International Biological Program was an attempt to apply the methods of big science to ecosystem ecology and pressing environmental issues. The IBP was organized under the leadership of C. H. Waddington beginning in 1962 and officially started in 1964, with the goal of exploring "The Biological Basis of Productivity and Human Welfare". In its early years, Canadian and European ecologists were the main participants; by 1968, the United States also became heavily involved. However, unlike other more successful applications of the big science model of scientific research, the IBP lacked a clear, socially and scientifically pressing goal. Many biologists, particularly molecular biologists and evolutionary ecologists, were sharply critical of the I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China (Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it covered th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Saxony
Lower Saxony (german: Niedersachsen ; nds, Neddersassen; stq, Läichsaksen) is a German state (') in northwestern Germany. It is the second-largest state by land area, with , and fourth-largest in population (8 million in 2021) among the 16 ' federated as the Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian are still spoken, albeit in declining numbers. Lower Saxony borders on (from north and clockwise) the North Sea, the states of Schleswig-Holstein, Hamburg, , Brandenburg, Saxony-Anhalt, Thuringia, Hesse and North Rhine-Westphalia, and the Netherlands. Furthermore, the state of Bremen forms two enclaves within Lower Saxony, one being the city of Bremen, the other its seaport, Bremerhaven (which is a semi-enclave, as it has a coastline). Lower Saxony thus borders more neighbours than any other single '. The state's largest cities are state capital Hanover, Braunschweig (Brunswick), Lüneburg, Osnabrück, Oldenburg, Hildesheim, Salzgitt ...

1974 Disestablishments
Major events in 1974 include the aftermath of the 1973 oil crisis and the resignation of United States President Richard Nixon following the Watergate scandal. In the Middle East, the aftermath of the 1973 Yom Kippur War determined politics; following Israeli Prime Minister Golda Meir's resignation in response to high Israeli casualties, she was succeeded by Yitzhak Rabin. In Europe, the invasion and occupation of northern Cyprus by Turkish troops initiated the Cyprus dispute, the Carnation Revolution took place in Portugal, and Chancellor of West Germany Willy Brandt resigned following an espionage scandal surrounding his secretary Günter Guillaume. In sports, the year was primarily dominated by the FIFA World Cup in West Germany, in which the German national team won the championship title, as well as The Rumble in the Jungle, a boxing match between Muhammad Ali and George Foreman in Zaire.

History Of Biology
The history of biology traces the study of the living world from ancient to modern times. Although the concept of ''biology'' as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were Vesalius and Harvey, who used experimentation and careful observation in physiology, and naturalists such as Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Antonie van Leeuwenho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Earth Science
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems o ...

Intergovernmental Science-Policy Platform On Biodiversity And Ecosystem Services
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an intergovernmental organization established to improve the interface between science and policy on issues of biodiversity and ecosystem services. It is intended to serve a similar role to the Intergovernmental Panel on Climate Change. Establishment and early development In 2010 a resolution by the 65th session of the United Nations General Assembly urged the United Nations Environment Programme to convene a plenary meeting to establish the IPBES. In 2013 an initial conceptual framework was adopted for the prospective IPBES plenary. From 29 April to 4 May 2019, representatives of the 132 IPBES members met in Paris, France, to receive the IPBES's full report and adopted a summary of it for policymakers. On 6 May 2019, the 40-page summary was released. 2020 report On October 29, 2020 the organization issued a preliminary report through Zenodo on its workshop, held virtually on 27– ...

Gerard Verschuuren
Gerard is a masculine forename of Proto-Germanic origin, variations of which exist in many Germanic and Romance languages. Like many other early Germanic names, it is dithematic, consisting of two meaningful constituents put together. In this case, those constituents are ''gari'' > ''ger-'' (meaning 'spear') and -''hard'' (meaning 'hard/strong/brave').

Forest Decline
Forest dieback (also "", a German loan word) is a condition in trees or woody plants in which peripheral parts are killed, either by pathogens, parasites or conditions like acid rain, drought, and more. These episodes can have disastrous consequences such as reduced resiliency of the ecosystem, disappearing important symbiotic relationships and thresholds. Some tipping points for major climate change forecast in the next century are directly related to forest diebacks. Definition Forest dieback refers to the phenomenon of a stand of trees losing health and dying without an obvious cause. This condition is also known as forest decline, forest damage, canopy level dieback, and stand level dieback. This usually affects individual species of trees, but can also affect multiple species. Dieback is an episodic event and may take on many locations and shapes. It can be along the perimeter, at specific elevations, or dispersed throughout the forest ecosystem. Forest dieback ...

Acid Rain
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinz Ellenberg
Heinz Ellenberg (1 August 1913 in Harburg (Elbe) – 2 May 1997 in Göttingen) was a German biologist, botanist and ecologist. Ellenberg was an advocate of viewing ecological systems through holistic means. He developed 9–point scales for rating European plant preferences for light, temperature, continentality (geographic region), nutrients, soil moisture, pH, and salinity. Life Ellenberg's father (a school teacher) died during World War I in 1914. From 1920 to 1932 Ellenberg studied in Hanover, where his interest in local flora and fauna was established, and where he came in contact with Reinhold Tüxen. In 1932 he moved to Montpellier, where he started his studies of ecology under the direction of Swiss ecologist Josias Braun-Blanquet. Later he studied botany, zoology, chemistry and geology in Heidelberg, Hanover and Göttingen, where he obtained a doctorate in 1938 in Göttingen under Franz Firbas. After completing his doctorate he worked at the central office for ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solling Project
The Solling () is a range of hills up to high in the Weser Uplands in the German state of Lower Saxony, whose extreme southerly foothills extend into Hesse and North Rhine-Westphalia. Inside Lower Saxony it is the second largest range of hills and the third highest after the Harz (Wurmberg; 971 m) and the Kaufungen Forest (Haferberg; 581 m). The Solling is a cultural landscape consisting mainly of spruce and beech forests. Oak also grows in some areas. The Solling forest is home of a number of animals and birds, for example red deer or chaffinch. They can best be observed in the ''Neuhaus wildlife park''. Together with the smaller and lower Vogler range and the little Burgberg to the north, the Solling is part of the Solling-Vogler Nature Park. Hills The main hills in the Solling include the following (heights given in m above Normalnull): * Große Blöße (527.8 m) * Großer Ahrensberg (524.9 m) * Moosberg (513.0 m) – with Hochsolling observatio ...
