Optimum macrobenthic sampling protocol for detecting pollution impacts in the Southern California Bight.

TL;DR: The optimum sampling protocol for detecting impacts was determined as that with the lowest total cost ×nmin on most measures, which may often be optimal for detecting important structural changes in macrobenthic communities with naturally high species richness and abundance.

Abstract: The optimum macrobenthic sampling protocol [sampling unit, sieve mesh size, and sample size (n)] was determined for detecting ecologically important pollution impacts in the Southern California Bight, U.S.A. Cost, in laboratory processing time, was determined for samples obtained using fourteen sampling units (0.005–0.1 m2 surface area) and two sieve mesh sizes (1.0 and 0.5 mm). Statistical power analyses for t-tests of means were performed to estimate the minimum sample size (nmin) needed to reliably (α=0.05, 1−β≧0.95) reject the null hypothesis of no difference between a reference and both a stimulated and a degraded station on twelve measures of community structure. The optimum sampling protocol for detecting impacts was determined as that with the lowest total cost ×nmin on most measures.

Taxonomic level sufficient for assessing pollution impacts on the southern california bight macrobenthos—revisited
Steven P. Ferraro,Faith A. Cole +1 more
TL;DR: The authors recommend family-level identification of specimens collected using the optimum sampling protocol when assessing macrobenthic community impacts in the study area because familial analyses are very likely to be sufficient.

Cost-effective monitoring of organic enrichment resulting from salmon mariculture
TL;DR: In this paper, two methods of environmental monitoring proposed for the salmon mariculture industry are compared and contrasted on the basis of scientific and cost-effectiveness criteria: a technique based on macrofaunal community structure and one using process-oriented sediment geochemistry.

Optimal benthic macrofaunal sampling protocol for detecting differences among four habitats in Willapa Bay, Washington, USA
Steven P. Ferraro,Faith A. Cole +1 more
TL;DR: As part of an effort to estimate estuarine habitat values with respect to ecological indicators of benthic macrofaunal community condition, an optimal sampling protocol (sample unit size, sieve mesh size, and sample number) was determined.

The influence of mesh size in environmental quality assessment of estuarine macrobenthic communities
TL;DR: In this article, the authors compared the performance of different ecological indicators based on data from 0.5 and 1-mm mesh sieves and compared the costs involved in using these two mesh sizes.

A Mathematical Theory Communication
TL;DR: Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication, published originally as a paper on communication theory more than fifty years ago.

Measurement of diversity
TL;DR: In this article, the authors define and examine a measure of concentration in terms of population constants, and examine the relationship between the characteristic and the index of diversity when both are applied to a logarithmic distribution.
