Phylogeography of white-spotted Charr (Salvelinus leucomaenis) inferred from mitochondrial DNA sequences.
The white-spotted charr (Salvelinus leucomaenis) is a coldwater-adapted fish distributed in far-eastern Asia. To assess phylogeographic patterns of this species over most of its range in the Japanese archipelago and Sakhalin Island, Russia, we examined nucleotide sequences of the mitochondrial DNA (mtDNA) cytochrome b region (557 bp) in 141 individuals from 50 populations. A total of 33 (5.5%) ...
متن کاملMitochondrial DNA population structure of the white-spotted Charr (Salvelinus leucomaenis) in the Lake Biwa water system.
A phylogeographic analysis of mitochondrial DNA sequences was performed in order to elucidate the origin, dispersal process, and genetic structure of white-spotted charr in the Lake Biwa water system. Two haplotypes were most common in the Lake Biwa water system, and were also common in the adjacent inlet rivers of the Sea of Japan. These results suggest that in the glacial periods of the Pleis...
متن کاملPost-cyclic transmission in Acanthocephalus tumescens (Acanthocephala: Echinorhynchidae).
The aim of this study was to investigate the post-cyclic transmission of Acanthocephalus tumescens (von Linstow, 1896) from Galaxias maculatus Jenyns to Oncorhynchus mykiss (Walbaum). Wild G. maculatus naturally infected with A. tumescens were fed to cultured rainbow trout, which were sacrificed at the second, third and fourth weeks post infection. Normally attached male and female acanthocepha...
متن کاملOvarian fluid enhances sperm velocity based on relatedness in lake trout, Salvelinus namaycush.
Studying mate choice at the gamete level can provide valuable insights into proximate mechanisms that underlie the evolution of mating systems. The objective was to assess whether ovarian fluid enhances sperm performance based on relatedness of mates in lake trout, Salvelinus namaycush, an iteroparous salmonid. Twelve trios were used, each composed of a female and two male fish; one male was re...
متن کاملThe effects of total dissolved solids on egg fertilization and water hardening in two salmonids--Arctic Grayling (Thymallus arcticus) and Dolly Varden (Salvelinus malma).
Previous studies have indicated that salmonid fertilization success may be very sensitive to elevated concentrations of total dissolved solids (TDS) with effects at concentrations as low as 250mgl(-1) being reported. However, interpretation of these studies is complicated by poor control performance and variable concentration response relationships. To address this, a series of experiments were...
