Does habitat specificity enhance genetic differentiation in two species of aquatic Podostemaceae in Japan?
The high-level genetic differentiations among populations of the two species may result from their limited dispersal. Their restricted habitats, which are primarily characterized by volcanic rocks in rapids and lower temperatures in winter, may enhance isolation among populations in distant rivers.
SCA11 presented as ADCA III according to Harding's classification and is a rare cause of spinocerebellar ataxia in Caucasians accounting for less than 1% of dominant ataxias in central Europe.
