摘要: Dynamics of macrobenthic animals were studied quantitatively during a 20-year period on tidal flats in the Wadden Sea. During this period, 4 winters very cold (mean temperature more than 2°C below long-term average), whereas also with 8 too mild succession occurred. No less 10 out total 28 species detail found to be sensitive winters. Their overwinter survival and numbers after severe winter lower normal or The polychaete bivalve among these probably died from low temperatures, 2 crustaceans moved deeper off-shore waters.
