Climate Change Impacts on Stoichiometry, Phytoplankton, and Zooplankton in Alpine Lake Food Webs
DownloadFall 2013
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...

Cumulative Impacts of Multiple Stressors on Aquatic Communities: Novel Fish Predators in Warming Mountain Lakes
DownloadFall 2015
Novel anthropogenic perturbations (i.e. stressors) often mediate the effects of each other, generating “ecological surprises”. While the cumulative impact of certain stressors on individual organisms and populations is becoming better understood, little is known about how their net effects...

Leavitt, P. R., Vinebrooke, R. D.
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...

Global warming is contributing to extreme climatic events, especially at higher elevations and latitudes. Phytoplankton assemblages are highly sensitive to these climate-related environmental changes, which include heatwaves and drought events. Knowledge gaps exist concerning the cumulative...

Fish Assemblages in Subarctic Lakes: Does Fire Affect Fish–Environment Relations in Northern Alberta?
Download2004
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...

Modelling phytoplankton across many scales: transient dynamics, human interactions, and niche differentiation in the light spectrum
DownloadFall 2021
In recent decades freshwater lakes have seen an increase in human presence. A common byproduct of this human presence is anthropogenic nutrient pollution resulting in eutrophication, a term that is becoming all too synonymous with harmful algal blooms. It is well known that phytoplankton...

Fall 2018
The Arctic and the North Atlantic Oceans are experiencing multiple stresses such as loss of sea ice, changing atmospheric patterns, increasing wind energy at the ocean surface and larger freshwater discharge to coastal regions. To address how the marine system may respond to these stresses I...
