Dataset on how mesopredator-mediated trophic cascade can break persistent phytoplankton blooms in coastal waters

Maximilian Berthold, Rhena Schumann, Volker Reiff, Rita Wulff & Hendrik Schubert
Managing eutrophied systems using only nutrient decreases to impose bottom-up control can be economically and ecologically challenging. Top-down controls through increased consumption have sometimes effectively controlled phytoplankton blooms. However, mechanistic insights, especially on possible trophic cascades, are less understood in brackish, species-poor coastal waters, where large cladocera are absent. In this study, we set up large mesocosms for three consecutive years during the growing season. One set of mesocosms contained mesopredators (gobies and shrimps), whereas...

Data from: Shifts in growth light optima among diatom species support their succession during the spring bloom in the Arctic

Diatoms of the Arctic Ocean annually experience extreme changes of light environment linked to photoperiodic cycles and seasonal variations of the snow and sea-ice cover extent and thickness which attenuate light penetration in the water column. Arctic diatom communities exploit this complex seasonal dynamic through a well-documented species succession during spring, beginning in sea-ice and culminating in massive phytoplankton blooms underneath sea-ice and in the marginal ice zone. The pattern of diatom taxa sequentially dominating...

Paleolimnological assessment of a hyper-eutrophic lake (Nowlans Lake, N.S., Canada) Cladoceran communities

Abbie Gail Jones, Andrew Labaj, Julia Campbell, Nell Libera & Joshua Kurek
Mink fur farming was once a widespread agricultural activity in southwestern Nova Scotia. Some freshwaters near mink fur farm operations now show severe water quality issues. Notably, the watershed of Nowlans Lake (southwestern Nova Scotia, Canada) once contained six mink farms as well as a fish meal feed processing plant. It is now one of the most productive lakes in Atlantic Canada, with exceedingly high measured Total Phosphorus concentrations. Here, we provide data from a...
