“…This also applies to polychaete assemblages, and especially to the Syllidae, which appear to be particularly sensitive to several forms of anthropogenic disturbance (e.g. trampling and sewage discharge) (Giangrande et al 2003, Casu et al 2006, Musco et al 2009). …”

The Syllidae are geographically widespread polychaetes, particularly diverse and abundant on marine hard bottoms and in seagrass meadows. Hydrodynamics, habitat complexity and biological traits are hypothesized to influence syllid bathymetric distribution. Little is known about the consistency of, or variation in, horizontal distribution patterns with varying depth. I analyzed hard-bottom Syllidae at 2 depths (1.5 and 5 m) at the scale of 1000s of metres, located around the Torre Guaceto marine protected area (MPA) (SE Italy) in order to (1) quantify syllid diversity and abundance, (2) describe their distribution pattern and (3) identify potentially important factors influencing their distribution. The Syllidae were dominant and highly diverse, and new biogeographic records were reported. Horizontal distribution patterns changed with depth, being more variable at 1.5 than 5 m. The presence of the MPA had little effect on alongshore variation in individual species abundance and assemblage structure. Contrary to expectations, there was no consistent relationship between Syllidae distribution and habitat-forming algal species. In contrast, syllid abundance varied with that of other invertebrates, suggesting that future research should focus on the role of interspecific interactions in syllid ecology. Syllidae are a highly diversified and widespread taxon that deserves special attention when analyzing biodiversity patterns of hard-bottom benthic communities.

“…Prior to this study, changes in polychaete communities in respect to different macrophyte assemblages were mostly assessed based on species level data (Abbiati et al, 1987;Giangrande, 1988;Giangrande et al, 2003;Casu et al, 2006;Pabis and Sicinski, 2010;Magalhaes and Bailey-Brock, 2014). It may be true that such analysis has many advantages.…”

“…In term of taxonomic level, most ecological studies in rocky intertidal shores have identified polychaetes up to the lowest taxonomic level (i.e. species level) (Abbiati et al, 1987;Giangrande, 1988;Giangrande et al, 2003;Casu et al, 2006;Pabis and Sicinski, 2010;Magalhaes and Bailey-Brock, 2014). Species based data analysis may provide strongest statistical results, but such analysis probably expends a lot of resources including time, cost, and taxonomist (Caughlan and Oakley, 2001;Kallimanis et al, 2012).…”

“…Over the 30 samples, the data will have generally a normal distribution, so the increasing of sample size may not increase the statistical benefits (Martnez-Abran, 2014). However, polychaetes show a spatial and temporal variability (Abbiati et al, 1987;Giangrande, 1988;Giangrande et al, 2003;Casu et al, 2006;Pabis and Sicinski, 2010;Magalhaes and Bailey-Brock, 2014). As a result, the data variation may differ between locations, and thus the "n = 30 rule of thumb" may not be always applicable (Martinez-Abran, 2014).…”

Taxonomic Level Needed to Detect Significant Changes in Polychaete Communities Over Different Macrophyte Assemblages on Rocky Intertidal Shores

Environmental degradation has more significant impacts on rocky intertidal communities after global changes increase progressively. Thus, ecological monitoring should be conducted properly to analyse potential drivers and their impacts. However, most of the ecological monitoring in rocky intertidal shores is more interested in macroalgae. Polychaetes associated with macrophyte assemblages should be also involved in the monitoring because they are important in determining coastal health and productivity. A successful ecological monitoring should consider three factors: taxonomic level, statistical power, and sample size. In this study, those factors were analysed in the relationships between polychaetes and macrophytes. Four taxonomic levels of polychaetes (i.e. order, family, genus, species) were tested based on 25 samples collected from rocky intertidal shores of Gunung Kidul, Yogyakarta, Indonesia. Relationships between each of taxonomic richness of polychaetes and each of macrophytes variables (i.e. species richness, biomass, species composition) were analysed using a Generalised Linear Models fitted by Poisson Distribution and log link. The statistical power of those relationships and the sample size needed to obtain a strong statistical power (>0.8) were also recorded. Relationships between each of taxonomic composition of polychaetes and each of macrophyte variables were analysed using a distance based Redundancy Analysis based on Bray Curtis dissimilarity on log(x+1) transformed abundance data with 999 permutations. Results showed that family based data analysis was sufficient to detect significant relationships between polychaetes and macrophytes. However, the statistical power of most relationships was relatively weak (< 0.8). Hence, the family-based data analysis should select a 44 sample size to gain significant relationships with a strong statistical power.
