#' This dataset is comprised of published (Ieno et al. 2006) and unpublished data (Oceanlab, University of Aberdeen). It
#' is a mesocosm replication experiment where density of a bristle worm (\emph{Hediste diversicolor}, Polychaeta) was 
#' manipulated along with habitat heterogeneity (presence or absence of algae) and sediment nutrient release measured. 
#' Bioturbation is an important aspect of nutrient recycling in oceanic and to a degree in lotic and lentic (think 
#' rivers and lakes) sediments.
#' 
#' Variables contained within this dataset are:
#' \itemize{
#'     \item MU: Denoting replicates within each \code{abundance} variable
#'     \item mesocosm: Index of batches within \code{nutrient} variable
#'     \item abundance: Allegedly the number of bristle worms
#'     \item biomass: Macrofaunal biomass measured in grams
#'     \item treatment: Whether algae were added or not
#'     \item nutrient: Nutrient measured (NO3, NH4, PO3)
#'     \item concentration: Concentration of a particular nutrient listed above
#' }
