DCCA

DCCA analysis of the 101-lake training set (empty circles) constrained to temperature (July Temp), depth and DOC (arrows). The Lake Silvaplana chironomid assemblages were added passively to this analysis. A 20-point moving average was made of the axis scores of the samples (thick line). Note that the two axes were shortened to represent the changes in the fossil records.
