The Kootenai River white sturgeon Acipenser transmontanus
is a landlocked population restricted to a 270 km stretch of the Kootenai River, which flows from western Montana through northern Idaho and into British Columbia. This population has shown an almost complete lack of natural juvenile recruitment since 1974. The total adult population in 1998 was estimated to be about 650 individuals and this fish is currently classified as endangered by the Ida...
متن کاملSite heteroplasmy in the mitochondrial cytochrome b gene of the sterlet sturgeon Acipenser ruthenus
Sturgeons are fish species with a complex biology. They are also characterized by complex aspects including polyploidization and easiness of hybridization. As with most of the Ponto-Caspian sturgeons, the populations of Acipenser ruthenus from the Danube have declined drastically during the last decades. This is the first report on mitochondrial point heteroplasmy in the cytochrome b gene of th...
متن کاملIntraspecific DNA sequence variation of the mitochondrial control region of white sturgeon (Acipenser transmontanus).
Intraspecific sequence variation in the D-loop region of mtDNA in white sturgeon (Acipenser transmontanus), a relict North American fish species, was examined in 27 individuals from populations of the Columbia and Fraser rivers. Thirty-three varied nucleotide positions were present in a 462-nucleotide D-loop sequence, amplified using the polymerase chain reaction. Bootstrapped neighbor-joining ...
متن کاملLength variation, heteroplasmy and sequence divergence in the mitochondrial DNA of four species of sturgeon (Acipenser).
The extent of mtDNA length variation and heteroplasmy as well as DNA sequences of the control region and two tRNA genes were determined for four North American sturgeon species: Acipenser transmontanus, A. medirostris, A. fulvescens and A. oxyrhnychus. Across the Continental Divide, a division in the occurrence of length variation and heteroplasmy was observed that was concordant with species b...
متن کاملMitochondrial DNA length variation and heteroplasmy in populations of white sturgeon (Acipenser transmontanus).
Southern blot analysis was used to quantify the extent of mtDNA D-loop length variation in two populations of white sturgeon, Acipenser transmontanus. Over 42% of individuals were heteroplasmic for up to six different mtDNA length variants attributable to varying copy numbers of an 82-bp repeat sequence. Chi-square analyses revealed that the frequencies of length genotypes and the incidence of ...
