Alternate Identifier:http://www.sciencemag.org/cgi/data/314/5800/787/DC1/1
Abstract:
We systematically searched major science, ecological and marine journals from 1960 to mid- 2005 for experiments that involved marine or estuarine organisms, conducted experiments including at least three species, measured some aspect of ecosystem functioning in mixedspecies and single-species treatments. Methods and data tables are part of the Supporting Online Material: Impacts of biodiversity loss on ocean ecosystem services. Science 3 November 2006: Vol. 314. no. 5800, pp. 787 - 790, DOI: 10.1126/science.1132294 Larger Marine Ecosystems, marine reserves and fishery closures information is including in the tables.

Methods and data sources

The following journals were searched: Science journals:Science, Nature, Proceedings of the National Academy of Sciences USA; Ecology journals:Ecology, Ecological Monographs, Ecological Applications, Oecologia, Oikos, Ecology Letters, Journal of Ecology, Journal of Animal Ecology; Marine journals: Limnology and Oceanography,Marine Biology, Marine Ecology Progress Series, Journal of Experimental Marine Biology andEcology, Journal of the Marine Biological Association of the United Kingdom.

We grouped studies according to trophic level (primary producer or consumer) and response variable (resource use, primary or secondary production, nutrient cycling, and resilience). For each variable, we conducted a meta-analysis comparing the log ratio of responses in the highest diversity treatment over the average of all single-species treatments. The effect size was weighted by the sample sizes and standard deviations derived from the original study. Response ratios were combined by fixed-effects meta-analysis. Weights for the log-response ratios were estimated based on sample variance and sample size from the individual studies.

Sampling Area And Frequency:
Coastal ecosystems focused on 12 estuarine and coastal ecosystems in North America, Europe, and Australia that form a broad temporal and spatial gradients of human impacts. We used an existing database that combines greater than 800 individual references on the history of human-induced ecological changes in these ecosystems covering palaeontological, archaeological, historical, fisheries and ecological records for species that have been of economical, structural, or functional significance throughout history).
Sampling Description:
Quantitative and qualitative records of abundance were combined to estimate relative abundance over time as pristine (100%), abundant (90%), depleted (50%), collapsed (10%), and extinct (0%) Recovery was defined as an increase of collapsed species to greater than 10% of abundance.
