Fatty acid composition of Cladocera and Copepoda from lakes of contrasting temperature
Summary We studied the fatty acid ( FA ) composition of six species of Cladocera and six species of Copepoda from five cold‐water lakes, situated in the tundra and/or in the mountains, and eight species of Cladocera and four species of Copepoda from eight warm‐water lakes (including one reservoir) i...
