We are currently conducting a meta-analysis of diversity-stability relations, specifically focusing on the how diversity-stability relations differ depending on experimental venue/ecological realism. If you have any published (or unpublished, i.e. thesis) data that could be re-analyzed to determine the effects of richness on community variability and either mean or observed population variability over time and would like to have your data included in the meta-analysis, your input would be greatly appreciated.
We are hoping to acquire data that includes the following information: 1) type of diversity manipulation (none/experimental), 2) unit of replication (field plot, mesocosm, pond, lab microcosm etc), 3) habitat type (terrestrial, aquatic), 4) length of experiment in days, 5) trophic level of both the manipulation and response variables (i.e, single, multiple), 6) response variable (biomass, abundance), 7) any additional factors that could be analyzed for patterns (i.e. nutrient, temperature, presence vs. absence of predators), 8) R and p-value for the effect of richness on community variability (CV) and mean or observed population variability (e.g. Tilman 1996). All data will be kept confidential and will not be used for any other analyses. Any assistance with this project would be greatly appreciated. Please contact me directly if you are interested in contributing or have any questions or suggestions. Thanks in advance! Tamara Romanuk -- Tamara N.
