High-Latitude Responses of Diatom and Chironomid Assemblages to Regional Climate Changes and Other Environmental Stressors
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 Diatom Assemblages in Adirondack (NY, USA) Reference Lakes Since Pre-Industrial Times
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 ...
Assessment of Long-Term Changes in Water Quality from Halifax Region Lakes (Nova Scotia, Canada) Using Paleolimnological Techniques
The current study developed a paleolimnological approach to assess changes in diatom assemblages (class Bacillariophyceae) from present-day lake sediments in comparison to those deposited before significant human impact ...
Large-Scale Exogenous Forcing of Long-Term Pacific Salmon Production and Ecosystem Interactions in Western North America
Pacific salmon (Oncorhynchus spp.) production strongly influences the ecosystems, cultures and economies of the Northeast Pacific. Historical variability in population sizes is complex, reflecting natural and human drivers. ...
