Zingel Balcanicus
''Zingel balcanicus'', the Vardar streber is a species of freshwater ray-finned fish in the family Percidae, the perches, ruffes, pikeperches and the darters. This species is endemic to the Vardar or Axios River in North Macedonia and its distribution may extend to the lower reaches of the river in Greece. Its biology is little known but other species in the genus ''Zingel'' require turbulent flows. Taxonomy ''Zingel balcanicus'' was first formally described as Asper streber balcanicus'' by the Yogoslav biologist Stanko Karaman with its type locality given as the Vardar River in the Republic of North Macedonia. This taxon is now considered to be a valid species within the genus ''Zingel'', the strebers and the zingel, within the subfamily Luciopercinae in the family Percidae. Etymology ''Zingel balcanicus'' is classified within the genus ''Zingel'', a name first coined by Hippolyte Cloquet as a tautonym when he proposed the genus ''Zingel'' with ''Cyprinus zingel'' as its ty ...

Stanko Karaman
Stanko Luka Karaman (8 December 1889 – 17 May 1959) was a Yugoslav biologist of Bosnian Serb ancestry, researcher on amphipod and isopod crustaceans. In 1926 he founded the Museum of South Serbia (later - Macedonian Museum of Natural History) in Skopje and in 1928, the Zoological Garden of Skopje. Several species are named after him, for example '' Delamarella karamani'' Petkovski, 1957 (Harpacticoida), '' Stygophalangium karamani'' Oudemans, 1933 (Arachnida), or '' Macedonethes stankoi'' I. Karaman, 2003 (Isopoda). Other taxa named ''karamani'' are labeled after his son Gordan S. Karaman, also a carcinologist This is a list of notable carcinologists. A carcinologist is a scientist who studies crustaceans or is otherwise involved in carcinology (the science of crustaceans). References {{Reflist, 24em Carcinologists, .

Luciopercinae
The Luciopercinae is a subfamily of ray-finned fish, classified within the Family (biology), family Percidae, the subfamily includes the pike-perches and zingels. The pike-perches of the genus ''Zander, Sander'' have an Holarctic distribution while the zingels of the Tribe (biology), tribe Romanichthyini are found in Europe. They are largely freshwater species but some can be found in brackish water. Characteristics The species within the Luciopercinae have a number of morphological characteristics in common. These are the possession of weak spines in the anal fin, the lateral line extending as far as the margin of the caudal fin and additional lines over and under the main lateral line, having a cleithrum which does not have serrations on the pectoral girdle, and having a vertebra count of 41–50. Distribution The Luciopercinae has a Holarctic distribution, the pike-perches of the genus ''Sander'' are found in Eurasia and North America and includes such commercially important s ...

Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributary, tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an Fish migration#Classification, anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to Spawn (biology), spawn after living two to three years in the ocean. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and Fish hatchery, hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent except Antarctica. Introductions to locations outside their nativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Treska
Treska (; ), is a river in the western part of North Macedonia, flowing for before joining the Vardar as its right tributary. With a basin covering 2,068 km2, the river originates high in the Stogovo mountain at about 2,000 metres elevation, initially flowing eastward through the Kičevo valley before making a sharp northward turn near Makedonski Brod and continuing through a narrow valley between the Suva Gora and Karadžica mountains to eventually meet the Vardar river near Skopje. The river system is known for its three major dams—Matka (built in 1937), Kozjak (2004), and Sveta Petka (2012)—as well as its diverse groundwater resources, which include isotropic aquifers in river valleys, fractured aquifers in mountainous regions, and particularly significant karst aquifers in limestone-rich areas that supply water to several towns in North Macedonia despite facing contamination risks from inadequate sewage infrastructure, unsanctioned landfills, intensive agriculture, a ...

Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balkan Peninsula
The Balkans ( , ), corresponding partially with the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Musala, , in the Rila mountain range, Bulgaria. The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of southeastern Europe spanning from the Adriatic Sea to the Black Sea. In the 19th century the term ''Balkan Peninsula'' was a synonym for Rumelia, the parts of Europe that were provinces of the Ottoman E ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) 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". Etymology 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 ...

Vernacular Name
Vernacular is the ordinary, informal, spoken form of language, particularly when perceived as having lower social status or less prestige than standard language, which is more codified, institutionally promoted, literary, or formal. More narrowly, a particular language variety that does not hold a widespread high-status perception, and sometimes even carries social stigma, is also called a vernacular, vernacular dialect, nonstandard dialect, etc. and is typically its speakers' native variety. Regardless of any such stigma, all nonstandard dialects are full-fledged varieties of language with their own consistent grammatical structure, sound system, body of vocabulary, etc. Overview Like any native language variety, a vernacular has an internally coherent system of grammar. It may be associated with a particular set of vocabulary, and spoken using a variety of accents, styles, and registers. As American linguist John McWhorter describes about a number of dialects spok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
