This week, we need to do work to address a component of our application that requires immediate attention. As a result, you may experience ERA to be intermittently available. We apologize for any inconvenience this may cause, and thank you for your patience as we attend to the care and feeding of ERA!

Factors involved in the ecology of Ruth Lake and Poplar Creek are discussed. Ruth Lake is a small, littoral, moderately eutrophic lake. It has clear water, a muddy substrate, and is shallow (mean depth 1.5m). Winter stagnation /occurred but the water was well oxygenated in summer....

Climate Change Impacts on Stoichiometry, Phytoplankton, and Zooplankton in Alpine Lake Food Webs
Download2013-11
The main hypothesis of this study was that warmer and drier conditions affect fishless alpine lakes by increasing (1) phosphorus (P)-availability, (2) P-limited autotrophs versus mixotrophic phytoflagellates, and (3) fast-growing P-limited cladocerans versus slower-growing nitrogen (N)-rich...

Differential sensitivities of benthic and planktonic communities to UV radiation may involve differences in habitat conditions (e.g., availability of physical refuge), taxonomic composition, UV-A (320-400 nm) and DNA-damaging UV-B (280-320 nm) irradiances, and potential indirect effects via...

Fish Assemblages in Subarctic Lakes: Does Fire Affect Fish–Environment Relations in Northern Alberta?

Tonn, W. M., Scrimgeour, G. J., Paszkowski, C. A., Aku, P. K. M., Boss, S. M.
In 1995, a wildfire swept through a large area of the Caribou Mountains, a remote subarctic plateau of northern Alberta, Canada, containing numerous unstudied and unexploited small lakes. To assess near-term effects of fire and to establish information on assemblage–environment relations in this...

Planktonic responses to nitrogen and phosphorus deposition - a natural alpine pond experiment
Download2010-11
Several lines of evidence suggest small alpine lakes and ponds are sensitive to nitrogen deposition. Paleolimnological studies, nutrient bioassays, and mesocosm experiments show the positive effects of nitrogen on aquatic alpine primary producers. In particular, alpine pond ecosystems have been...
