To describe the distribution of the observed bites by herbivores on different benthic taxa, the bites per minute on each benthic group for each herbivore species were averaged, and data were transformed using log (x + 1) to account for the large number of zeros in the dataset (Anderson et al. 2008). ...

Because it resides in oligo- to mesotrophic lakes, where a UV impact exists in the epilimnion, a reaction to both factors is possible. Also in D. pulex a respon ...
