International Society Of Limnology
The International Society of Limnology (SIL) is an international scientific society that disseminates information among limnology, limnologists, those who study all aspects of inland waters, including their physics, chemistry, biology, geology, and Water resources management, management. It was founded by August Thienemann and Einar Naumann in 1922 as the International Association of Theoretical and Applied Limnology and Societas Internationalis Limnologiae. It had about 2.800 members in 2008. SIL celebrated its 100th anniversary at a meeting in Berlin, Germany in August 2022. SIL publishes the following scientific publications: * the journal ''Fundamental and Applied Limnology:Archiv für Hydrobiologie'' ; prior to 2007, it was called ''Archiv für Hydrobiologie''. * Communications (Mitteilungen), irregular publication. * Limnology in Developing Countries, a book series. * Congress proceedings, until 2007, published as ''Verhandlungen Internationale Vereinigung für theoreti ...

Scientific Society
A learned society (; also learned academy, scholarly society, or academic association) is an organization that exists to promote an academic discipline, profession, or a group of related disciplines such as the arts and science. Membership may be open to all, may require possession of some qualification, or may be an honour conferred by election. Most learned societies are non-profit organizations, and many are professional associations. Their activities typically include holding regular conferences for the presentation and discussion of new research results and publishing or sponsoring academic journals in their discipline. Some also act as professional bodies, regulating the activities of their members in the public interest or the collective interest of the membership. History Some of the oldest learned societies are the Académie des Jeux floraux (founded 1323), the Sodalitas Litterarum Vistulana (founded 1488), the Accademia della Crusca (founded 1583), the Accademia de ...

Limnology
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to underst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Water Resources Management
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water. Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities. Water resources are under threat from water scarcity, water pollution, water conflict and climate change. Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, with depletion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Thienemann
August Friedrich Thienemann (7 September 1882 in Gotha – 22 April 1960 in Plön) was a German limnologist, zoologist and ecologist. He studied zoology at the University of Greifswald. He was an associate Professor of Hydrobiology at the University of Kiel, and director of the former Hydrobiologische Anstalt der Kaiser-Wilhelm-Gesellschaft (now the Max-Planck-Institut für Limnologie) at Plön. A co-founder of Societas Internationalis Limnologiae, Thienemann is best known for his work on the biology of the Chironomidae, and his contributions to the field of lake typology. He also introduced the concept of trophic level terminology in 1920. Over the course of his career, Thienemann published 460 works. One of his more noted students was Carmel Humphries, an Irish expert in Chironomidae The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Einar Naumann
Einar Christian Leonard Naumann (13 August 1891 – 22 September 1934) was a Swedish botanist and limnologist who was professor of limnology at the University of Lund. Naumann worked during the summers at the Fishery Station in Aneboda (Småland, Southern Sweden), where he established a field laboratory of the Limnological Institute in Lund (now Einar Naumann Field Station). In 1921 he suggested the establishment of an international association of limnologists to a visiting German colleague, August Thienemann. The following year, on Thursday, August 3, 1922, Naumann and Theinemann co-founded the Societas Internationalis Limnologiae at a meeting held in the auditorium of the Zoological Institute of Kiel University, Germany.75th Anniversary of SIL http://www.umanitoba.ca/outreach/sil/news/25/75_anniversary.html Naumann is also widely known for his contributions to lake typology, and specifically for introducing the terms oligotrophic, eutrophic and dystrophic lake Dystrophic ...

Freshwater Biological Association
The Freshwater Biological Association (FBA) is an independent scientific organisation founded in 1929 in Cumbria by Felix Eugen Fritsch, William Harold Pearsall, Francis Balfour-Browne, and Robert Gurney among others. Whilst originally created to be a research station it has evolved into a learned society whose mission is "to promote the sustainable management of freshwater ecosystems and resources, using the best available science". It works closely alongside other organisations, notably Natural Environment Research Council. The FBA promotes freshwater science through innovative research, maintained specialist scientific facilities, a programme of scientific meetings, production of publications, and by providing sound independent scientific opinion. As of 2010, the FBA hosted both published and unpublished collections, two specialist libraries and varieties of long term data sets from sites of scientific significance. It is managed by the Chief Executive who was assisted by 25 sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earth Sciences Organizations
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
