The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Freshwater Fish Of Europe
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 i ...

Knipowitschia
''Knipowitschia'' is a genus of marine, fresh and brackish water gobies native to Eurasia. The genus name almost certainly honours Nikolai Mikhailovich Knipovich (1862-1938), a biologist who led a number of expeditions to the Caspian Sea. Species There are currently 17 recognized species in this genus: * '' Knipowitschia byblisia'' Ahnelt, 2011 (Byblis goby) * '' Knipowitschia cameliae'' Nalbant & Oţel, 1995 (Danube delta dwarf goby) * ''Knipowitschia caucasica'' ( L. S. Berg, 1916) (Caucasian dwarf goby) * '' Knipowitschia caunosi'' Ahnelt, 2011 (Caunos goby) * '' Knipowitschia croatica'' Mrakovčić, Kerovec, Mišetić & D. Schneider, 1996 (Neretva dwarf goby) * '' Knipowitschia ephesi'' Ahnelt, 1995 * '' Knipowitschia goerneri'' Ahnelt, 1991 (Corfu dwarf goby) * '' Knipowitschia iljini'' L. S. Berg, 1931 * '' Knipowitschia longecaudata'' (Kessler, 1877) (Longtail dwarf goby) * '' Knipowitschia mermere'' Ahnelt, 1995 * '' Knipowitschia milleri'' ( Ahnelt & Bianco, 1 ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ...

University Of Zagreb
The University of Zagreb ( hr, Sveučilište u Zagrebu, ; la, Universitas Studiorum Zagrabiensis) is the largest Croatian university and the oldest continuously operating university in the area covering Central Europe south of Vienna and all of Southeastern Europe. The University of Zagreb and the University North are the only public universities operating in Northern and Central Croatia. The history of the University began on September 23, 1669, when the Holy Roman Emperor Leopold I issued a decree granting the establishment of the ''Jesuit Academy of the Royal Free City of Zagreb''. The decree was accepted at the Council of the Croatian Kingdom on November 3, 1671. The Academy was run by the Jesuits for more than a century until the order was dissolved by Pope Clement XIV in 1773. In 1776, Empress Maria Theresa issued a decree founding the ''Royal Academy of Science'' which succeeded the previous Jesuit Academy. Bishop Josip Juraj Strossmayer proposed the founding of a Univ ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ...

Krka (Croatia)
Krka () is a river in Croatia's Dalmatia region, known for its numerous waterfalls. It is long and its basin covers an area of . It was known in ancient Greek language, ancient Greek as ''Kyrikos'', or may be also as ''Catarbates'' (literally "steeply falling") by the Ancient Greece, ancient Greeks, it was known to the Ancient Rome, ancient Romans as ''Titius'', ''Corcoras'', or ''Korkoras''. Course The river has its source near the border of Croatia with Bosnia and Herzegovina, at the foot of the Dinara mountain. After meandering through the Krčić canyon, it enters the Polje, karst valley of Knin through the Krčić waterfall of . At the foot of the second, called the Topoljski waterfall, of these is a spring in a cave with of passage. The river then flows through the valley, where it is fed by the Kosovčica on the left and the Orašnica and the Butižnica on the right, passing the Knin Fortress, Fortress of Knin between the last two on the way, and into the main canyon. ...
