Cytogenetic Studies in North American Minnows (cyprinidae). Iv. Somatic Polyploidy in Gila Bicolor
The kidney tissue of a single individual of the California minnow Gila bicolor (Girard) contained polyploid cells in about 1.7% frequency. Chromosome spreads of triploid, tetraploid, hexaploid, octaploid, and dodecaploid cells were observed and may have arisen thmugh endoreduplication of ancestral diploid and triploid cells. The cytological mechanism producing the triploid cells is unknown. Dip...
متن کاملThe relationship of spawning mode tb- conservation of North American minnows (Cyprinidae)
Approximately 20% of North American minnows are considered imperiled. The factors responsible for imperilment in this group are complex, but the relationship of spawning mode to conservation of North American minnows has not been explored. 1 provide a summary of the spawning modes of imperiled North American minnows, discuss patterns between these modes and conservation status, and predict the ...
متن کاملPhylogenetic and taxonomic relationships of northern Far Eastern phoxinin minnows, Phoxinus and Rhynchocypris (Pisces, Cyprinidae), as inferred from allozyme and mitochondrial 16S rRNA sequence analyses.
Analyses of allozyme (18 loci) and partial mitochondrial DNA (mtDNA) sequences (1295 bp, 16S rRNA) support the classification of phoxinin minnows from the northern Far East into 2 genera of 8 species: Phoxinus phoxinus, Rhynchocypris oxycephalus, R. perenurus, R. czekanowskii, R. kumgangensis, R. semotilus, R. lagowskii and R. sp. (bergi ?). Although R. lagowskii from Japan and the Amur basin a...
متن کاملIs evolution gradual or rectangular? Evidence from living fishes.
The traditional view that most evolutionary change is gradual and cumulative within lineages (phyletic gradualism) has recently been challenged by the proposition that the majority of evolutionary change is concentrated within speciation events (rectangular evolution). The logical implications of these competing hypotheses for the means and variances of genetic distance among living members of ...

The Caspian Sea basin is one of the most important ecosystems in Iran with a high diversity of different aquatic species, so that the issue of determining the taxonomy its fishes has always been considered. Up to now, a total of 297 species of freshwater and brackish fish have been reported from Iran where the subfamily Leuciscinae (minnows) has a high diversity of species in the Caspian Sea ba...
