Macrofaunal Community

Macrofaunal community composition of ten exposed sandy beaches in northern New South Wales, Australia, appeared to correlate with beach morphodynamic state even though the data represented sampling at only a single time. Better results were obtained by using the Beach State Index (BSI) rather than the dimensionless fall velocity (?). Species number and abundance significantly increased as the BSI value increased, whereas biomass was not correlated with BSI. The New South Wales beaches had a higher species number and abundance relative to BSI than did beaches in a published review of beaches around the world.

This is the first of a series describing new turbellarian and nematode species collected during March and April 1992, on eulittoral sandy shores of Southern Queensland and northern New South Wales, Australia. The environment and all sampling sites are described. Four new species of Macrostomida (Dunwlchia arenosa, gen. et sp. nov., Bradburia australiensis, gen. et sp. nov., Macrostomum australiense, sp. nov., and Macrostomum sp. based only on female sexual maturity) were found in eulittoral habitats of sandy beaches, flats and brackish-water creeks.

Log Normal

The effects of an outfall of low-volume, tertiary-treated effluent were evaluated within Jervis Bay on the southern coast of New South Wales by using the macrofauna inhabiting kelp (Ecklonia radiata) holdfasts. A range of analytical methods was used to determine differences in faunistic patterns between six sites (three close to the outfall and three controls) in the winters of 1990 and 1991. The analyses indicated that community structure was highly variable over both the spatial and the temporal scales of the study. Although some of the methods provided results consistent with a perturbed environment on the first sampling occasion (ABC plots, log-normal plots), these patterns were not repeated on the second sampling occasion. In addition, the species primarily responsible for the 'perturbed' configuration with those methods were from taxa that have been highlighted as pollution-sensitive in other studies of holdfast fauna. Non-parametric multivariate statistical methods (MDS, ANOSIM) consistently showed significant differences among sites but also revealed highly significant differences within a site over time. There was no consistent difference between sites closest to the outfall and more distant sampling locations and so no outfall effect was suggested. The results indicate that natural environmental factors are more influential than the low-volume, tertiary-treated effluent from the outfall in determining patterns of community structure in the holdfast community within Jervis Bay.

Zonation Patterns

The geographical distribution, habitat separation, reproductive periodicity, fecundity, population size structure, and other life-history features of several crustaceans dominant in four sandy beaches of south-eastern New South Wales were studied. The species examined include the cirolanid isopods Pseudolana concinna and P. towrae, the exoedicerotid amphipods Exoediceroides maculosus and Exoediceros fossor, the urohaustoriid amphipod Urohaustorius metungi, and the zobrachoid amphipod Bumeralius buchalius. Closely related species were generally separated by habitat, with the exception of U. metungi and B. buchalius, which occurred together on some beaches. In these two species, ecological separation was evident in zonation patterns, size of individuals, and reproductive seasonality.
