Hemispheric-scale patterns of climate-related shifts in planktonic diatoms from North American and European lakes
A synthesis of over 200 diatom-based paleolimnological records from nonacidified/nonenriched lakes reveals remarkably similar taxon-specific shifts across the Northern Hemisphere since the 19thExpand

Climate-driven regime shifts in the biological communities of arctic lakes.
Fifty-five paleolimnological records from lakes in the circumpolar Arctic reveal widespread species changes and ecological reorganizations in algae and invertebrate communities since approximatelyExpand

Lake diatom responses to warming: reviewing the evidence
Algae, the dominant primary producers in many aquatic ecosystems, are critical to global biogeochemical cycling, and changes in their abundance and composition can cascade throughout aquatic foodExpand

Trends in Surface Water Chemistry in Acidified Areas in Europe and North America from 1990 to 2008
Acidification of lakes and rivers is still an environmental concern despite reduced emissions of acidifying compounds. We analysed trends in surface water chemistry of 173 acid-sensitive sites fromExpand

Reconstruction of multi-century flood histories from oxbow lake sediments, Peace-Athabasca Delta, Canada
Floods caused by ice-jams on the Peace River are considered to be important for maintaining hydro-ecological conditions of perched basins in the Peace-Athabasca Delta (PAD), Canada, a highlyExpand

Long-term trends in zooplankton of Dorset, Ontario, lakes: the probable interactive effects of changes in pH, total phosphorus, dissolved organic carbon, and predators
Time trends in abundance, body size, species richness, and species composition indicate that crustacean zooplankton communities of southern Canadian Shield lakes changed between 1980 and 2003. TotalExpand

Cladocera assemblages from the surface sediments of south-central Ontario (Canada) lakes and their relationships to measured environmental variables
Fossil cladoceran remains preserved in surface sediment samples from 44 oligotrophic lakes in south-central Ontario were examined to evaluate the relationships between species assemblages andExpand

Do spectrally inferred determinations of chlorophyll a reflect trends in lake trophic status?
Visible reflectance spectroscopy (VRS) has been used to reconstruct lake sediment chlorophyll a concentrations. Despite good concordance between inferred and measured chlorophyll a values, questionsExpand

Relationships between dissolved organic carbon concentrations, weather, and acidification in small Boreal Shield lakes
We used multiple linear regression analyses to explore empirical relationships between dissolved organic carbon (DOC) concentrations, weather, and acidification in long-term data sets from 12 smallExpand
