“…Periphytic ciliates utilize a variety of food supplies (e.g., algae/bacteria/detritus, etc. ), the bases of which are generally planktonic in origin (Wang and Xu 2015;Weitere et al 2003). The colonization processes of marine periphytic ciliates can, therefore, be shaped by the response of their food supply to changes in environmental conditions (e.g., sunlight, microalgae and nutrients) at different depths in water column (Abdullah Al et al 2018b;Xu et al 2009a, b;Zhang et al 2013).…”

Colonization features of biofilm-dwelling protozoa, especially ciliates, are routinely used as a useful tool for marine bioassessment. In this review, we summarize some of these features to develop an optimal sampling strategy for using biofilmdwelling protozoa as bioindicators of marine water quality. We focus on the utility of: (1) diversity indices to analyze the colonization features of biofilm-dwelling protozoa for monitoring marine water quality; (2) MacArthur-Wilson and logistic equation models to determine spatio-temporal variations in colonization dynamics; and (3) homogeneity in taxonomic breadth of biofilm-dwelling protozoa during the process of colonization. The main findings are that: (1) the colonization dynamics of biofilm-dwelling protozoa are similar at depths of 1-5 m in spring and autumn; (2) temporal variability was well fitted to the MacArthur-Wilson and logistic models (P < 0.05); and (3) species composition reached an equilibrium after a colonization period of 10-14 days in spring and autumn, but this took less time in the summer and more time in the winter. Ellipse-plotting tests demonstrated spatial variability in homogeneity in taxonomic structure of the ciliate communities at different depths in the water column, with high levels at 1 m and 2 m and lower levels at 3.5 m and 5 m. Thus, the findings of this review suggest that the colonization dynamics of biofilm-dwelling protozoa may be influenced by different depths and seasons in coastal waters and 1-2 m in spring and autumn may be optimal sampling strategy for bioassessment on large spatial/temporal scales in marine ecosystems.

“…Periphytic ciliates feed on a variety of microbial food (e.g. bacteria, algae, detritus), the sources of which are commonly either of planktonic origin or suspended in the water column (Weitere et al ., 2003; Parry, 2004; Scherwass et al ., 2005; Wang & Xu, 2015; Wang et al ., 2017). Therefore, the colonization dynamics of periphytic ciliates can be shaped by their food supply in response to changes in water conditions at different water depths in the water column (e.g.…”

The colonization features of ciliate communities have proved to be a useful tool for indicating water quality status in aquatic ecosystems. To determine an optimal water depth for bioassessment using these ecological bioindicators, the colonization process of periphytic ciliates was studied at four depths of 1, 2, 3.5 and 5 m in Chinese coastal waters. Samples were collected at time intervals of 3, 7, 10, 14, 21 and 28 days using glass slides. The periphytic ciliate communities represented similar colonization dynamics from a depth of 1 to 3.5 m: (1) the temporal variability was well fitted to the MacArthur-Wilson and logistic models; (2) the species composition reached an equilibrium during the exposure time periods of 10–14 days; and (3) the maximum abundances were definitely higher at a depth of 1 m than those at 3.5 m. PERMANOVA test revealed that the colonization pattern at 1 m depth was significantly different from those at the other three depths. Results suggest that the colonization dynamics of periphytic ciliates may be influenced by water depth in coastal waters. These findings provide an important reference for establishing an optimal sampling strategy for bioassessment on large spatial/temporal scales in marine ecosystems.

Previous studies have demonstrated that during the primary colonization process, the individual abundances of functional groups generally increase and then equilibrate, following the logistic growth model equation (Zhang et al ., 2012; Wang & Xu, 2015). Based on our data, the increase in carbon biomass of all four functional groups were significantly fitted to the logistic equation.…”

Biofilm-dwelling ciliates are a primary component of a biofilm, and play an important role in the functioning of microbial food webs by mediating carbon and energy flux into benthos from plankton. The carbon flux of biofilm-dwelling ciliates was studied at different trophic-functional levels within the colonization process in coastal waters of the Yellow Sea, northern China from May to June 2015. Samples were collected, using a glass slide method, at the time intervals of 1, 3, 7, 10, 14, 21 and 28 days from depths of 1 and 3 m. The carbon biomass of both total ciliates and all trophic-functional groups increased following the logistic growth curve model. During the whole colonization period, the bacterivores and non-selectives were generally the primary contributor to the carbon flux in young samples (<14 days), while the algivores and raptors predominated mature samples (14–28 days) at both depths. In terms of mature samples, however, the non-selectives and algivores were the primary contributors at a depth of 1 m, while the raptors accounted for primary contributions to the carbon flux at a depth of 3 m. Although the times to 50% maximum carbon biomasses were generally ranged 24 days at both depths, the maximum carbon biomasses were significantly higher at depth of 3 m than at 1 m. These results may provide useful information for ecological research on carbon flux from plankton to benthos in marine ecosystems.
