A population genetics toolbox for the threatened canopy-forming brown seaweeds Cystoseira tamariscifolia and C. amentacea (Fucales, Sargassaceae)

The brown macroalga Cystoseira tamariscifolia is a foundation species along the northeastern Atlantic and western Mediterranean Sea. It occurs from lower intertidal rock pools to the shallow subtidal. Anthropogenic pollution and rising seawater temperatures can threaten its local distributions. In order to address impacts of historical and current environmental changes, to quantify effective dispersal and population connectivity, and to provide...
