WebFeb 7, 2024 · The cluster association of the seven CONISS clusters with geochemical elements can also be investigated in the PCA biplot (Fig. 4). Cluster 1 shows a large spread in the biplot, with approximately one half of it strongly negative on PC1 and highly correlated with LOI and DBD, whereas the other half plots close to the centre of the biplot (Fig. 4 ). WebJun 13, 2014 · CONISS cluster analysis indicated that the cladoceran communities in the three ecological zones (typical tundra, southern tundra and forest-tundra) differed in their taxonomic composition and structure. Differences in the cladoceran assemblages were related to limnological features and geographical position, vegetation type, climate and …
WebA constrained hierarchical cluster analysis (Grimm, 1987) was performed using a Bray–Curtis distance and CONISS linkage method to define chironomid stratigraphic zones. The statistical significance of the clusters was assessed using a broken-stick model (Bennett, 1996). For diversity analysis, rarefaction was calculated (Engels et al., 2024).
