Due to the uncertainty in pointing out whether the damage originates from laboratory treatment or from autochthonous processes, the indicator value of fair graded spines in this study is negligible. Changes in Daphnia preservation in Lake Kivijärvi According to the statistically significant core zonation, the greatest shift in Daphnia preservation occurred at the depth of 9 cm (~1925) and was clearly reflected by changes in proportions of different grades.	cache/aiol-6293.pdf	txt/aiol-6293.txt
