Changes in mixing depth reduce phytoplankton biomass in an Arctic lake: Results from a whole-lake experiment

ABSTRACT Research has revealed contradictory responses of primary producers in Arctic lakes to increasing temperatures, making it unclear how future warming and climate change will alter lake

Wind regime changes in the Euro-Atlantic region driven by Late-Holocene Grand Solar Minima

Understanding atmospheric response to radiative forcing, including the intensity and distribution of wind patterns is critical as this might have important implications in the coming decades.

Ecosystem responses to abrupt climatic and environmental change in southern Siberia during the Late Quaternary

The Late Quaternary documents climatic changes over a number of timescales. These are well studied in many regions, including Northern Europe, but much less so in some critical areas. One such region

Deciphering Climate-Driven Changes in Planktonic Diatom Communities in Lake Superior

Neoglacial trends in diatom dynamics from a small alpine lake in the Qinling mountains of central China

Abstract. During the latter stages of the Holocene, and prior to anthropogenic global warming, the Earth underwent a period of cooling called the neoglacial. The neoglacial is associated with

Nutrient limitation status of Arctic lakes affects the responses of Cyclotella sensu lato diatom species to light: implications for distribution patterns

It is found that light affected Cyclotella growth rates, cell densities, and distribution patterns differently depending on lake nutrient limitation status, and helps to clarify some of the complex distribution patterns of planktonic diatom taxa found in lakes of many areas around the Arctic as well as at lower latitudes.

Physical characteristics of northern forested lakes predict sensitivity to climate change

Evidence suggests that boreal-lake ecosystems are changing rapidly, but with variable ecological responses, due to climate warming. Paleolimnological analysis of 27 undeveloped northern forested



Dominant Factors Controlling Variability in the Ionic Composition of West Greenland Lakes

Over 80 lakes were sampled between the ice margin and the coast in West Greenland between 66 and 67°N and analyzed for their pH, alkalinity, conductivity, and major ions. Most of the lakes (67%) are

A caveat regarding diatom-inferred nitrogen concentrations in oligotrophic lakes

Atmospheric deposition of reactive nitrogen (Nr) has enriched oligotrophic lakes with nitrogen (N) in many regions of the world and elicited dramatic changes in diatom community structure. The

Recent Changes in the Diatom Community Structure of Lakes in the Beartooth Mountain Range, U.S.A.

Abstract In alpine lakes from several regions of the world, sedimentary diatom profiles indicate that rapid shifts in diatom community structure have occurred over the past century. A number of these

Diatoms reveal complex spatial and temporal patterns of recent limnological change in West Greenland

Diatoms in sediment cores were analysed across a range of stratigraphic resolutions along a transect of 23 lakes spanning the ice-free margin of the west coast of Greenland (~67°N), to explore

Climate change 2007: Impacts, Adaptation and Vulnerability. Contribution of Working Group II to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. Summary for Policymakers.

The Intergovernmental Panel on Climate Change (IPCC) was set up jointly by the World Meteorological Organization and the United Nations Environment Programme to provide an authoritative international

Rank Transformations as a Bridge between Parametric and Nonparametric Statistics

Abstract Many of the more useful and powerful nonparametric procedures may be presented in a unified manner by treating them as rank transformation procedures. Rank transformation procedures are ones

Lake diatom response to recent Arctic warming in Finnish Lapland

High‐resolution palaeolimnological data from a number of remote and nonpolluted lakes in Finnish Lapland reveal a distinct change in diatom assemblages. This parallels the post‐19th century Arctic

Ecology and spatial distributions of surface-sediment diatoms from 77 lakes in the subarctic Canadian treeline region

It is indicated that both forest-tundra and arctic tundra lakes differed significantly in diatom assemblage composition from boreal forest lakes, and trends provide important information on the variability of aquatic ecosystems across this climatically sensitive vegetational gradient.
