Salvelinus alpinus

Røye eller arktisk røye ( Salvelinus alpinus ) er en fisk i laksefamilien. Den var blant de første ferskvannsfiskene som innvandret til Norge etter siste istid. Arten har sitt norske navn etter den røde fargen (røyr). Røya har en sirkumpolar utbredelse på den nordlige halvkule.

Its distribution is circumpolar.

It spawns in fresh water and populations can be lacustrine, riverine or anadromous, where they return from the ocean to their fresh water . It has a circumpolar distribution, and it is considered the most northern of all freshwater fishes. Its body colour is largely dependent on the location, season and sexual maturity of the individual, but is generally silver-white, sometimes becoming bright orange on the underside . Some populations, known as dwarf char, grow to only around 10–cm. Appearance: Like many other members of the salmon family . Арктический голец — рыба семейства лососевых, образует множество форм : проходных, озёрно-речных и озёрных.

Ареал проходной формы кольцеобразно охватывает весь полярный круг и области к северу и югу от него.

Проходные гольцы идут на нерест в реки Норвегии, Исландии, Шпицбергена, . The basis for the project was the detection of G. Historical data indicate that G. Hein CL(1), Ohlund G, Englund G.

To study the genetic divergence between small benthic morphs and limnetic morphs, we conducted RNA-sequencing charr embryos at four . In the High Arctic, charr is the only fish found in many lakes. Many arctic charr populations . Enligt gällande taxonomi räknas dessa nu som former inom röding S.

Beroende på miljön uppvisar enskilda bestånd olika livshistoriestrategier med reproduktionen förlagd till rinnande vatten i enartsbestånd i högfjällsmiljö, och längs grund och stränder i lägre sjöar med andra fiskarter. Rödingen är en kallstenoterm . Variation in presumably neutral genetic markers can inform us about evolvability, historical effective population sizes and phylogeographic history of contemporary populations.
