About the Image

Silver-plated models of Sphagnum branches were employed in studies of boundary layer properties. The model based on morphology of S. trinitense (left; an aquatic species) generated thinner boundary layers than the S. recurvum model (right; a nonaquatic species) when evaluated in an electrochemical fluid tunnel. Models are 10 times life size with the branch axes 10 cm long.
