Spatial distribution of Champsocephalus gunnari in Subarea 48.3. Some implications for parameter estimation
Abstract: Results of the analysis of three consecutive cruises to subarea 48.3 are analyzed. A ... significant variance component associated with the formation of clusters of stations was found as well as a ... general trend for increasing densities since 1994. The significant variance component obtained for ... (as in the estimation of the variance of the mean density) might result in a gross underestimation of ...
