TL;DR: Fifty-five paleolimnological records from lakes in the circumpolar Arctic reveal widespread species changes and ecological reorganizations in algae and invertebrate communities since approximately anno Domini 1850, indicating that the opportunity to study arctic ecosystems unaffected by human influences may have disappeared.

TL;DR: In this paper, the Qu'Appelle Valley drainage system provides water to a third of the population of the Canadian Great Plains, yet is plagued by poor water quality, excess plant growth, and periodic fish kills.

TL;DR: Results from six training set lakes suggest that a minimum abundance of 40–50 head capsules is sufficient for use in inference models, however more diverse samples likely require more than 50 head capsules.

TL;DR: In this paper, the authors review the more recent studies on zoobenthos responses to changes in lake productivity and to altered sublittoral and hypolimnetic oxygen conditions, as reflected from subfossil midge assemblages and palaeostratigraphies.
