Density of Acanthocyclops vernalis, Leptodiaptomus tyrelli and Daphnia pulicaria in Hidden Lake (Banff, AB, Canada) from 2014 to 2020

This data file is the combination of two data sets of two different methodology (The Derry lab and Fisher lab; see method section for differences). The density of three dominant species were assessed every summer during the same week from 2014 to 2020 by the Fisher lab in Hidden Lake, Banff National Park, Canada: the cyclopoid Acanthocyclops vernalis, the calanoid Leptodiaptomus tyrelli and the cladocera Daphnia pulicaria. An extra sampling effort was done by the Derry lab around the rotenone treatments. The objective of this study was to assess the effect of two rotenone application (in summer 2018 and 2019) on zooplankton populations.
