| A nuclear power plant is set up at Flamanville (Channel; West coast of the Cotentin). For monitoring studies, one species (or a group of species) has been chosen in each major unit for a reference population dynamics study. Hard bottoms are covered by several species of barnacles. These species present different temperature affinities, and have reached here an equilibrium stage. The recruitment period of Balanus balanoides, the main species, has been determined. A relationship is established between the wintry temperature and the numerical importance of its spring recruitment. |
