Diatoms from the surface sediments of the Skagerrak and the Kattegat and their relationship to the spatial changes of environmental variables
Abstract:This paper deals with the distribution of diatoms in the surface sediments of the Skagerrak and the Kattegat and its correlation with the spatial changes of eight environmental variables. Eigenvalues and the values of the species‐environmental correlation show that the measured environment variables account for the major gradients of diatom composition. The results of forward selection of the environmental variables and Monte Carlo permutation tests of statistical significance, together with canonical coefficients and intra‐set correlations between environmental variables and the axes, show that summer and winter surface salinities are the most important environmental factors affecting diatom distribution in this area. Five diatom assemblages are distinguished in the Skagerrak and the Kattegat. The distribution of these assemblages is clearly correlated with the strong variations in salinity, and in particular with surface salinities during summer and winter.
