Genomic population structure of freshwater‐resident and anadromous ide (Leuciscus idus) in north‐western Europe
Climate change experts largely agree that future climate change and associated rises in oceanic water levels over the upcoming decades, will affect marine salinity levels. The subsequent effects on fish communities in estuarine ecosystems however, are less clear. One species that is likely to become increasingly affected by changes in salinity is the ide (Leuciscus idus). The ide is a stenohali...
متن کاملGonadogenesis in chub Squalius (Leuciscus) cephalus (L. 1758).
The chub is an opportunistic, rheophilic cyprinid species and popular gamefish distributed throughout almost all of Europe, South Caucasus and part of Anatolia. It is most abundant in small rivers and large streams. The process of anatomical and cytological differentiation was analyzed in chub gonads. Material used in the study was derived from artificial spawning of adult individuals caught in...
متن کاملTranscriptional Profiling Reveals Differential Gene Expression of Amur Ide (Leuciscus waleckii) during Spawning Migration
Amur ide (Leuciscus waleckii), an important aquaculture species, inhabits neutral freshwater but can tolerate high salinity or alkalinity. As an extreme example, the population in Dali Nor lake inhabits alkalized soda water permanently, and migrates from alkaline water to neutral freshwater to spawn. In this study, we performed comparative transcriptome profiling study on the livers of Amur ide...
متن کاملUse of the chromosomal co-location of the minor 5S and the major 28S rDNA as a cytogenetic marker within the genus Leuciscus (Pisces, Cyprinidae).
The chromosomes of three species from the genus Leuciscus (the ide L. idus, the European chub L. cephalus and the common dace L. leuciscus) were examined with the FISH technique for 5S and 28S rDNA probes. The analysis showed that among the three examined species, 5S rDNA signals were located on two large and four small subtelocentric chromosomes in L. leuciscus, on one large and five small sub...
متن کاملGenomic Basis of Adaptive Evolution: The Survival of Amur Ide (Leuciscus waleckii) in an Extremely Alkaline Environment
The Amur ide (Leuciscus waleckii) is a cyprinid fish that is widely distributed in Northeast Asia. The Lake Dali Nur population inhabits one of the most extreme aquatic environments on Earth, with an alkalinity up to 50 mmol/L (pH 9.6), thus providing an exceptional model with which to characterize the mechanisms of genomic evolution underlying adaptation to extreme environments. Here, we devel...
