Balanus balanoides (L.) on the Atlantic coast of France: Further observations on the small isolated population at the southern limit of its distribution at Arcachon

Abstract

Balanus Balanoides is present as a small, isolated and even locally restricted population on the west coast of France at Arcachon. Observations of the past few years indicate an increase in numbers. Growth and survival are best in shaded places-possibly due to these affording some protection from high summer temperatures.
