Firehead Tetra
''Petitella bleheri'' is a species of characin found in Amazon Basin in Brazil and Peru. It is one of three species commonly referred to as the rummy-nose tetra, and is also known as the firehead tetra. Taxonomy and systematics The specific name, ''bleheri'', honors the species’ discoverer, Heiko Bleher. The mitochondrial genome of ''Petitella bleheri'' was fully sequenced in 2015 using standard polymerase chain reaction (PCR) techniques, and found to be 17,021 base pairs long. Distribution and habitat This species is found in the Rio Negro and Rio Meta basins. Diet Omnivorous and will accept just about anything offered. Species does have a small mouth so correspondingly sized foods are best. Feed a mixture of dried flakes and granules and small live and frozen foods. A varied diet such as this is essential for the best colour development. In the aquarium This species is common in the aquarium trade. Between the years of 2006 to 2015, 7,178,906 specimens of ''Petit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Gery
Ancient and noble French family names, Jacques, Jacq, or James are believed to originate from the Middle Ages in the historic northwest Brittany region in France, and have since spread around the world over the centuries. To date, there are over one hundred identified noble families related to the surname by the Nobility & Gentry of Great Britain & Ireland. Origins The origin of this surname ultimately originates from the Latin, Jacobus which belongs to an unknown progenitor. Jacobus comes from the Hebrew name, Yaakov, which translates as "one who follows" or "to follow after". Ancient history A French knight returning from the Crusades in the Holy Lands probably adopted the surname from "Saint Jacques" (or "James the Greater"). James the Greater was one of Jesus' Twelve Apostles, and is believed to be the first martyred apostle. Being endowed with this surname was an honor at the time and it is likely that the Church allowed it because of acts during the Crusades. Indeed, ...

Rio Meta
The Meta River is a major left tributary of the Orinoco River in eastern Colombia and southern Venezuela, South America. The Meta originates in the Eastern Ranges of the Andes and flows through the Meta Department, Colombia as the confluence of the Humea, Guatiquía and Guayuriba rivers. It flows east-northeastward across the Llanos Orientales ("Eastern Plains") of Colombia following the direction of the Meta Fault. The Meta forms the northern boundary of Vichada Department, first with Casanare Department, then with Arauca Department, and finally with Venezuela, down to Puerto Carreño where it flows into the Orinoco. The Meta River is long and its drainage basin is . The Meta divides the Colombian Llanos in two different parts: the western portion on the left bank is more humid, receives the relatively nutrient-rich sediments from the Andean mountain range and therefore soils and tributaries are also nutrient-rich, while the eastern portion, ''high plain'' or ''altillanura'' ...

Taxa Named By Jacques Géry
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Peru
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...

Tetras Of Brazil
Terrestrial Trunked Radio (TETRA; formerly known as Trans-European Trunked Radio), a European standard for a trunked radio system, is a professional mobile radio and two-way transceiver specification. TETRA was specifically designed for use by government agencies, emergency services, (police forces, fire departments, ambulance) for public safety networks, rail transport staff for train radios, transport services and the military. TETRA is the European version of trunked radio, similar to Project 25. TETRA is a European Telecommunications Standards Institute (ETSI) standard, first version published 1995; it is mentioned by the European Radiocommunications Committee (ERC). Description TETRA uses time-division multiple access (TDMA) with four user channels on one radio carrier and 25 kHz spacing between carriers. Both point-to-point and point-to-multipoint transfer can be used. Digital data transmission is also included in the standard though at a low data rate. TETRA Mobi ...

Export
An export in international trade is a good produced in one country that is sold into another country or a service provided in one country for a national or resident of another country. The seller of such goods or the service provider is an ''exporter''; the foreign buyer is an '' importer''. Services that figure in international trade include financial, accounting and other professional services, tourism, education as well as intellectual property rights. Exportation of goods often requires the involvement of customs authorities. Firms Many manufacturing firms begin their global expansion as exporters and only later switch to another mode for serving a foreign market. Barriers There are four main types of export barriers: motivational, informational, operational/resource-based, and knowledge. Trade barriers are laws, regulations, policy, or practices that protect domestically made products from foreign competition. While restrictive business practices sometimes hav ...

Live Fish Trade
The live fish trade can refer to the live food fish trade (for human consumption) or to the ornamental fish trade (for aquariums). The fish can come from many places, but most comes from Southeast Asia. The live food fish trade is a global system that links fishing communities with markets, primarily in Hong Kong and mainland China. Many of the fish are captured on coral reefs in Southeast Asia or the Pacific Island nations. Consumer demand Within the live food trade there are certain types of fish demanded more often by consumers, particularly smaller and medium-sized fish. According to the book While Stocks Last: The Live Reef Food Fish Trade consumer demand has caused the fish captured on coral reefs to be the most valued fish in the trade. Consumers are important because they are directly purchasing these fish species at restaurants and stores. In addition to these types of fishes, many juvenile fish are used for the live food trade. There are also cultural and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
