The growth histories of two populations of Bouchardia antarctica Buckman from the La Meseta Formation, Seymour Island, Antarctica, have been determined by means of growth-line analysis. Adult specimens in the first population were consistently smaller than those in a second population which were collected 120 metres higher up in the succession. The two populations had previously been subdivided into two species, but are now recognised as being conspecific. Adults of both populations consistently display up to 10 prominent, evenly-spaced growth-lines. On specimens from the lower population the mean growth-line spacing on the dorsal valve is 1.83 mm; the comparable figure for the larger population further up the sequence is 2.85 mm. This i...
