Popis: | The spatial variations of periphytic ciliate functional traits to environmental heterogeneity during an annual cycle were studied at functional trait resolution in a typical coastal area of the Yellow Sea. Samples were monthly collected using microscopic glass slides at four sampling sites within a gradient of pollution during 1-year cycle. The second-stage analysis was carried out to explore the interactions of annual variations in functional traits of the periphytic ciliates among four sampling sites. Results demonstrated that (1) the functional traits of the periphytic ciliates showed clear spatial variations in annual cycle along the gradient of pollution; and (2) the spatial variations of the ciliate functional pattern in annual cycle were significantly associated with the changes of environmental conditions, especially the COD and nutrients among four study sites, either alone or in association with DO and pH. The results suggested that the annual pattern of functional traits might reflect the environmental heterogeneity in marine ecosystems. |
