“…The multivariate model null hypothesis (25) is less restrictive than the univariate model null hypothesis (24) because F (R) uses a fixed covariance structure (i.e., K(K+1)/12) in the denominator (Marascuilo & McSweeney, 1967), thus implying compound symmetry of the covariance matrix. Thus, the null hypothesis in (24) implies sphericity because it translates to the assumption that the errors are IID[0, σ ε 2 ] for all j and k from the univariate model null hypothesis in (16).…”

“…For comparing the J independent groups, a set of pairwise or group combination contrasts would most likely be of interest for defining a. For comparing the K repeated measures either pairwise, polynomial, or trend contrasts would most typically define b (Lix & Keselman, 1996;Marascuilo & McSweeney, 1967). In some cases, it may be desirable to normalize the trend coefficients, b, so that the metric of the repeated measures variable will not ψ change, thus making confidence intervals more interpretable.…”

“…Both the McSweeney (1967) and Hettmansperger (1984) alignment procedures were developed for the two-way betweensubjects factorial design and thus are not desirable because they do not remove the subjects' individual differences effect that is nested in the between-subjects factor. To elaborate, the data from a split-plot design has three nuisance parameters that must be removed in order to align the scores for ranking and subsequent analysis of interaction effects.…”

Three aligned rank methods for transforming data from multiple group repeated measures (split-plot) designs are reviewed. Univariate and multivariate statistics for testing the interaction in split-plot designs are elaborated. Computational examples are presented to provide a context for performing these ranking procedures and statistical tests. SAS/IML and SPSS syntax code to perform the procedures is included in the Appendix.

Several epibiotic species reduce starfish (Asterias rubens) preference for the blue mussel Mytilus edulis in the Baltic. The aim of this study was to reveal whether this associational resistance was caused by structural or chemical aspects of the different epibionts. To assess structural epibiont effects, an in situ experiment was conducted with unfouled mussels and mussels equipped with artificial epibionts ('dummies') exposed to natural predation by A. rubens. The chemically inert dummies closely matched the structural properties of the locally common epibionts Balanus improvisus (barnacle), Ceramium strictum (red alga), Halichondria panicea (sponge), and Laomedea flexuosa (hydrozoan). Starfish fed indiscriminately in all treatments. Chemical effects of epibionts on the attractiveness of mussels for A. rubens were investigated by incorporating freeze-dried epibionts or mussel tissue into Phytagel pellets at natural concentrations. Starfish were allowed to choose among these structurally similar but chemically different prey items in an in vitro experiment. The predators exhibited significant preferences among the food pellets, which closely matched their preferences for corresponding natural mussel-epibiont associations. Thus, chemical aspects of epibionts appear to play a larger role in this associational resistance than do structural aspects. Implications of these indirect interactions for benthic communities are discussed.

“…To test the hypothesis 2 (about individual variation in antipredator responses among the microenvironments to the same stimulus), we compared the proportions of 0 and 1 among the three microenvironments for the first (approach) and second (touch) stimuli independently. Here we also used Cochran test, followed by the multiple comparison procedure of Marascuilo and McSweeney (1967). To test the hypothesis 3 (about the individual variation in jumped distance among the microenvironments to the same stimulus), we compared the jumped distances by individuals in the three microenvironments by using an ANCOVA, in which body size were entered as covariate.…”
