The present review provides a framework within which the impact of dredging on biological
resources that live on the sea bed (“Benthic” communities) can be understood, and places in …

Meiofauna are ubiquitous in estuaries worldwide averaging 106 m− 2. Abundance and
species composition are controlled primarily by three physical factors: sediment particle size …

Biological Diversity provides an up to date, authoritative review of the methods of measuring
and assessing biological diversity, together with their application. The book's emphasis is on …

In the early 1980s, a strategy for graphical representation of multivariate (multi‐species)
abundance data was introduced into marine ecology by, among others, Field, et al.(1982). A …

The method of choice for multivariate representation of community structure is often non-
metric multi-dimensional scaling (MDS). This has great flexibility in accommodating …

Much sampling to detect and quantify human environmental disturbances is flawed by a lack
of appropriate replication. BACI (Before—After—Control—Impact) designs have only a …

We demonstrate a contlnuoui decrease in the taxonomic dlstlnctness of a marlne
assemblage along a gradient of Increasing env~ ronmental contamination, In a situat~ on …

The large, sparse arrays of species counts arising in both field and experimental community
studies do not lend themselves to standard statistical tests based on multivariate normality …

It is critical that the impacts of environmental stressors on natural systems are detected,
monitored and assessed accurately in order to legislate effectively and to protect and restore …

The measurement of changes in the structure of natural marine communities is widely used
for the detection and monitoring of man's impact on the sea. Such studies are almost always …
