Changes in benthic communities along a presumed pollution gradient in Vancouver Harbour

Samples of macrobenthic organisms were obtained at seven stations on a presumed pollution gradient from the head of Vancouver Harbour through to outer Howe Sound. Polychaetes (83 apparent species) and molluscs (43 apparent species) were the most abundant faunal groups numerically (44.8 and 47.9%, respectively). Molluscs accounted for most of the biomass (87.9%). The following univariate and multivariate methods were used to investigate structural changes in the benthic communities: ANOVA, Abundance–Biomass Comparisons and related statistics, cluster analysis, multidimensional scaling, and the BIOENV procedure. Most of the analyses divided the seven stations into three groups: Port Moody Arm (Inner Harbour): two stations; Inner and Outer Harbour: four stations, and Gibsons (Howe Sound): one station. Further cause–effect investigations are needed to determine the sensitivity to organic pollution of indicator species identified in the survey. However our data correlating benthic community changes to sediment chemistry suggest the inner harbour was dominated by pollution-tolerant species. Depth and sediment grain size were confounding factors for the interpretations.

In this paper, we report results of a collaborative benthic sampling and analysis program carried out during the PICESWorksho p to examine benthic habitats in Vancouver Harbour along a presumed pollution gradient and into the Strait of Georgia. The primary objective of the project was to share expertise and approaches among the various investigators. results were also used to compare pollution assessment methods based on measurements at various levels in the ecosystem (e.g., cellular vs. individual organism vs. community responses)
