Using drift coefficients as a basis for inferring times, effective population sizes, and genetic adaptations

Genetic drift and gene flow can give rise to a complex population genetic structure. The inverse problem of estimating the genetic drift and gene flow in the past, based on the present-day genomic population structure, can be solved using an admixture graph. This describes the di...

Identity of herbivorous fishes preventing the restoration of Sargassum beds in Nagasaki Prefecture, southwestern Japan

Abstract Despite the widely recognized impact of fish herbivory on macroalgae, few studies have quantified the specific contributions of individual species in Japan. We used visual censuses along belt transects to investigate the abundance of herbivorous fishes, and measured fish...
