Ramsar Wetland
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over .

Socio-hydrology
Socio-hydrology; socio (from the Latin word ''socius,'' meaning ‘companion) and hydrology (from the Greek: ὕδωρ, "hýdōr" meaning "water"; and λόγος, "lógos" meaning "study") is an interdisciplinary field studying the dynamic interactions and feedbacks between water and people. Areas of research in socio-hydrology include the historical study of the interplay between hydrological and social processes, comparative analysis of the co-evolution and self-organization of human and water systems in different cultures, and process-based modelling of coupled human-water systems. Furthermore, socio-hydrology has been presented as one of the most relevant challenges for the Anthropocene, in relationship with its aims at unraveling dynamic cross-scale interactions and feedbacks between natural and human processes that give rise to many water sustainability challenges. Socio‐hydrology is also predicted to be an important license for modellers. Overview In traditional hydrolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecohydrology
Ecohydrology (from Greek , ''oikos'', "house(hold)"; , ''hydōr'', "water"; and , '' -logia'') is an interdisciplinary scientific field studying the interactions between water and ecological systems. It is considered a sub discipline of hydrology, with an ecological focus. These interactions may take place within water bodies, such as rivers and lakes, or on land, in forests, deserts, and other terrestrial ecosystems. Areas of research in ecohydrology include transpiration and plant water use, adaption of organisms to their water environment, influence of vegetation and benthic plants on stream flow and function, and feedbacks between ecological processes, the soil carbon sponge and the hydrological cycle. Key concepts The hydrologic cycle describes the continuous movement of water on, above, and below the surface on the earth. This flow is altered by ecosystems at numerous points. Transpiration from plants provides the majority of flow of water to the atmosphere. Water is infl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etroplus Suratensis
The green chromide (''Etroplus suratensis'') is a species of cichlid fish that is native to fresh and brackish water habitats in some parts in India such as Kerala, Goa, Chilika Lake in Odisha and Sri Lanka. The species was first described by Marcus Elieser Bloch in 1790. This species and other members of the genus ''Etroplus'' are relatively closely related to the ''Paretroplus'' cichlids from Madagascar. Other common names include pearlspot cichlid, banded pearlspot, and striped chromide. In Kerala, it is known locally as ''karimeen''. In Tamil Nadu, it is known locally as the ''pappan'' or ''pappa'' In Goa, the fish is known as ''kalundar''. In Odisha, the local name is ''kundal''. In Sri Lanka this fish is known as ''Mal koraliya''. It has been introduced in various parts of the world outside its native range, including Singapore, where it occurs in estuaries. The Government of Kerala declared pearlspot as the official fish of Kerala. Habitat and behavior The green chr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alectis Ciliaris
The African pompano (''Alectis ciliaris''), also known as the pennant-fish or threadfin trevally, is a widely distributed species of List of marine aquarium fish species, tropical marine fish in the jack family, Carangidae. The species is found in tropical waters worldwide, with adults often inhabiting coastlines, while juveniles are usually pelagic, floating with ocean currents. The adult African pompano is similar in appearance to the other members of the genus ''Alectis'', with the concave shape of the head near the eyes; the clearest distinguishing feature. The juveniles are similar to other members of ''Alectis'', having long, filamentous dorsal fin, dorsal and anal fin tips which are thought to discourage predators. The species lives in depths less than 100 m, consuming a range of crustaceans and small fishes. The species is of minor fishery, economic importance, often taken amongst other tropical midwater fishes by hook and line, while juveniles are occasionally caught in b ...

Penaeus
''Penaeus'' is a genus of prawns, including the giant tiger prawn (''P. monodon''), the most important species of farmed crustacean worldwide. The genus has been reorganised following a proposition of Pérez Farfante and Kensley based on morphological differences, in particular the genital characteristics of these animals, although this revision has not been universally accepted. Following the revision, many species formerly in the genus ''Penaeus'' have been reassigned to new genera in the family Penaeidae: ''Farfantepenaeus'', '' Fenneropenaeus'', ''Litopenaeus'' and ''Marsupenaeus''. The following table gives an overview: A few more species that are sometimes given as ''Penaeus'' spp. are actually assigned to the genus ''Melicertus ''Melicertus'' is a genus of "king" prawns, comprising eight species which were previously classified as members of the genus ''Penaeus'': *''Melicertus canaliculatus'' (Olivier, 1811) - witch prawn *''Melicertus hathor'' (Burkenroad, 1959) ...

Socio-economic
Socioeconomics (also known as social economics) is the social science that studies how economic activity affects and is shaped by social processes. In general it analyzes how modern societies progress, stagnate, or regress because of their local or regional economy, or the global economy. Overview “Socioeconomics” is sometimes used as an umbrella term for various areas of inquiry. The term “social economics” may refer broadly to the "use of economics in the study of society". More narrowly, contemporary practice considers behavioral interactions of individuals and groups through social capital and social "markets" (not excluding, for example, sorting by marriage) and the formation of social norms. In the relation of economics to social values. A distinct supplemental usage describes social economics as "a discipline studying the reciprocal relationship between economic science on the one hand and social philosophy, ethics, and human dignity on the other" toward social ...

Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
