Algae, the dominant primary producers in many aquatic ecosystems, are critical to global
biogeochemical cycling, and changes in their abundance and composition can cascade …

Fresh waters are particularly vulnerable to climate change because (i) many species within
these fragmented habitats have limited abilities to disperse as the environment changes;(ii) …

Fifty-five paleolimnological records from lakes in the circumpolar Arctic reveal widespread
species changes and ecological reorganizations in algae and invertebrate communities …

Executive summary Physical and biological systems on all continents and in most oceans
are already being affected by recent climate changes, particularly regional temperature …

One of the greatest challenges faced by limnologists, as well as most ecologists and
environmental scientists, is finding data with time scales appropriate to their questions …

We live in a constantly changing environment, yet tracking ecological change is often very
difficult. Long‐term monitoring data are frequently lacking and are especially sparse from …

Despite their generally isolated geographic locations, the freshwaters of the north are
subjected to a wide spectrum of environmental stressors. High-latitude regions are …

Using a whole-watershed approach and a combination of historical, contemporary, modeled
and paleolimnological datasets, we show that the High Arctic's largest lake by volume (Lake …
