“…Groups A and B were the primary contributors to the ciliate communities. This result was consistent with the previous reports on benthic microfauna: even though a large number of species may be present, only a few commonly were the primary contributor to the communities (Azovsky, 1988; Fernandez-Leborans & Fernandez-Fernandez, 2002; Burkovskii et al , 2011; Zhang et al , 2012). It should be noted that the consumers (B and N) were the primary contributors driving the shift in functional pattern of the ciliate communities in both systems.…”

The colonization dynamics in trophic-functional structure of biofilm-dwelling ciliate fauna were studied using two methods based on an artificial substratum in Korean coastal waters of the Yellow Sea during April 2007. Polyurethane foam enveloped slide (PFES) and conventional slide (CS) systems were used to collect ciliate samples at a depth of 1 m. The ciliate fauna represented similar colonization dynamics in trophic-functional patterns that were driven mainly by the algivores, bacterivores and non-selectives in both systems. Simple trophic-functional patterns (e.g. algivores and non-selectives) occurred within the ciliate fauna at the initial stage (1–3 days), while complex patterns (e.g. algivores, non-selectives and bacterivores) were established at the transitional (5–7 days) and equilibrium (9–19 days) stages. However, the time in which ciliate fauna reached a stable trophic-functional pattern was shorter in the PFES than in the CS system. Among four trophic-functional types, the algivores and bacterivores significantly fitted the MacArthur-Wilson and logistic models in colonization and growth curves in both systems, respectively. Furthermore, the species richness and diversity of algivores and bacterivores were significantly higher in the PFES system than in the CS. These results suggest that the PFES system was more effective than the conventional slide method for a colonization survey on trophic-functional patterns of biofilm-dwelling ciliate fauna in marine ecosystems.

“…The functional parameters based on colonization analysis are useful indicators for assessing the carrying capacity of external organic load/toxic levels of ecosystems (Zhang et al ., 2012, 2013). For example, the lower the pollution levels were, the higher the values of S eq and G (Cairns & Henebry, 1982; Burkovskii & Mazei, 2001; Xu et al ., 2009 a , 2009 b ; Burkovskii et al ., 2011; Zhang et al ., 2012, 2013). In this study, the colonization rate ( G ), S eq , N max showed a clear vertical variability from a depth of 1 to 5 m in water columns.…”

“…However, these parameters generally levelled off at stable values at depths of 1 to 3.5 m. This implies that availability of food supply due to light intensity in deeper water depths might influence the colonization succession with lower abundance and higher variability at different depths. Another reason might be organic load, because higher organic pollutants can minimize the carrying capacity of ecosystems and have been reported elsewhere and are consistent with our present findings (Burkovskii & Mazei, 2001; Burkovskii et al ., 2011; Zhang et al ., 2012, 2013).…”

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.

“…According to previous reports, microeukaryotic organisms commonly follow the MacArthur-Wilson equilibrium model in terms of species number and the logistic growth equation for numbers of individuals during the process of colonization (Cairns and Henebry 1982;MacArthur and Wilson 1967;Railkin 1995). The colonization process can be divided into three separate phases: initial (1-7 days old), transitional (7-10 days old) and equilibrium (10-28 days old) (Burkvoskii et al 2011;Burkovskii and Mazei 2001;Sonntag et al 2006). It was previously reported that the value of S eq (estimated equilibrium of species number) is generally negatively correlated with concentrations of organic pollutants and toxic compounds; while, the value of G (colonization rate constant) is generally higher in waters with lower environmental stress (Burkvoskii et al 2011;Burkovskii and Mazei 2001;Cairns and Henebry 1982;Xu et al 2009b).…”

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.
