"This study examines the varnish clam, Nuttallia obscurata, population at different tidal elevations in Whaling Station Bay (WSB), Hornby Island, British Columbia. Three stations corresponding to different tidal elevations (mid, low and high) were sampled for varnish clam population attributes as well as sediment grain size. Understanding varnish clam preferences with respect to tidal elevation and substrate texture may provide insight in to the invasive potential of varnish clams as well as their impact on native species. Collecting and assessing varnish clams at three locations along the intertidal zone also allowed examination of clam size, age and health as a function of intertidal elevation"--Introd., p. 2.
