ABSTRACT: Under the critical environmental conditions of the White Sea, Lepidonotus squamatus and Harmothoe imbricata coexist in the same habitat, often showing recurrent alternations in dominance. L. squamatus is a long-living, slow growing broadcast spawner, while H. imbricata is a short-living and quick growing species, with complex reproductive behaviour. These different life strategies may allow them to respond in a different way to the environmental limitations of the study site, this likely being the most appropriate explanation to the observed alternation in dominance.
KEY WORDS: Population dynamics; growth; scale-worms; the White Sea.
