High-Latitude Responses of Diatom and Chironomid Assemblages to Regional Climate Changes and Other Environmental Stressors
(2015-07-03)
High-latitude freshwater ecosystems are amongst the most vulnerable to climate change impacts. However, the response to warming is rarely straightforward and may be modulated by local or regional factors, producing variability ...
Changes in Scaled-Chrsyophyte Assemblages in Response to Recent Climate Change in Northwestern Ontario
(2011-09-30)
A two-part paleolimnological study was conducted to: i) understand the important factors that are related to the present-day distribution of scaled-chrysophytes; ii) investigate changes in the scaled-chrysophyte assemblages ...
Changes in Diatom Assemblages in Adirondack (NY, USA) Reference Lakes Since Pre-Industrial Times
(2014-05-30)
The vast majority of Adirondack lakes have been impacted since pre-industrial time through either regional (e.g. acidification) or local (e.g. fish stocking, liming, seepage of road salt, cultural eutrophication) environmental ...
Acidification and Climate Warming: Understanding the Impact of Multiple Anthropogenic Stressors on Adirondack (NY, USA) Lakes
(2014-05-05)
Lakes in the Adirondack Park (NY, USA) are undergoing chemical recovery from acidification. There is now a pressing research need to define recovery targets for acid-impacted sites. Researchers attempting to designate such ...
Phenotypic Plasticity Drives Phenological Change in Mandt's Black Guillemot (Cepphus Grylle MandtII)
The ability of individuals to change breeding time is predicted to be an important aspect of adapting to climate change. Changes in breeding time could occur through either behavioural adjustment of breeding time or ...
The Response of Discostella Species to Climate Change at the Experimental Lakes Area, Canada
(2014-07-02)
Global climate change is threatening both our water quality and quantity. Specifically, the influence of climate change on freshwater lakes includes decreased water availability, increased evapotranspiration, changes in ...
Cladoceran Responses to Environmental Change in High Elevation Andean Lakes
Andean lakes are hotspots of biodiversity and serve as critical freshwater resources for millions of people. However, little information is available regarding their ecological responses to anthropogenic climate change, ...
Effects of soil resource and herbivory manipulation on temperate-mesic grassland vegetation under a changing climate
Water availability is obviously a primary regulator of plant productivity and species interactions in arid ecosystems, where many previous studies have documented these effects by manipulating soil moisture availability. ...
Tracking Long-Term Holocene Climate Trends in Lake 239 (Experimental Lakes Area, NW Ontario) Using Diatoms, Pollen, and Charcoal
(2010-07-15)
The boreal forest region of Canada is climatically sensitive and may be impacted by anthropogenic-induced climatic changes. The results of this multi-proxy paleolimnological study contribute detailed information on changes ...
