摘要

The colonization dynamics in trophic-functional patterns of periphytic protist communities was studied in coastal waters of the Yellow Sea, northern China, from May to June, 2010. The periphytic protists represented different trophic-functional structures during colonization process. Only certain trophic-functional groups (e.g., photoauto trophs, algivores and non-selectives) occurred within the protist communities with low species number and abundance at the initial stage (1-3 days), while more trophic-functional groups (e.g., photoautotrophs, algivores, non-selectives and raptors) contributed to the communities with increased and peaked species number and abundance at the transitional (7-10 days) and equilibrium (14-28 days) stages, respec tively. All heterotrophic groups were significantly fitted the MacArthur-Wilson model in colonization curves and rep resented higher species number and colonization rates at a depth of 1 m than at 3 m. These results may provide neces sary understandings for ecological researches and monitor ing programs using periphytic protists with different colonization ages in marine ecosystems.
