Experimental Iron Amendment Suppresses Toxic Cyanobacteria in a Hypereutrophic Lake
(Wiley, 2016-02-25)The effects of reducing nutrient inputs to lakes and reservoirs are often delayed by hysteresis resulting from internal phosphorus (P) loading from sediments. Consequently, controlling harmful algal blooms (HABs) in many ... -
Naphthenic Acid Fraction Compounds Reduce the Reproductive Success of Wood Frogs (Rana Sylvatica) By Affecting Offspring Viability
(Elsevier, 2022-10-18)Understanding the toxicity of organic compounds in oil sands process-affected water (OSPW) is necessary to inform the development of environmental guidelines related to wastewater management in Canada's oil sands region. ... -
Experimental Evidence from the Field that Naturally Weathered Microplastics Accumulate Cyanobacterial Toxins in Eutrophic Lakes
(Wiley, 2022-09-23)Freshwater ecosystems with recurring harmful algal blooms can also be polluted with plastics. As such, the two environmental problems may interact. To test if microplastics influence the partitioning of microcystins in ... -
Temporal Evolution of Critical Traits and their Relationship to Cod Stock Collapse and Recovery
(Canadian Science Publishing, 2022-06-08)The North Atlantic Fisheries Organization response to a precipitous decline of the Flemish Cap cod (Gadus morhua) stock during the 1990s was the imposition of an 11-y moratorium on directed fishing for cod; recovery followed. ... -
A framework for 210Pb model selection and its application to 37 cores from Eastern Canada to identify the dynamics and drivers of lake sedimentation rates
(Wiley, 2022-04-26)Lake sedimentation rate represents a synthetic metric of ecosystem functioning. Many localized studies have reported a significant association between land use/land cover changes and lake sediment mass accumulation rates, ... -
An Integrative Perspective On the Mechanistic Basis of Context- Dependent Species Interactions
(Oxford University Press, 2022-05-24)It has long been known that the outcome of species interactions depends on the environmental context in which they occur. Climate change research has sparked a renewed interest in context-dependent species interactions ... -
Developing diatom-based inference models to assess lake ecosystem change along a gradient of metal smelting impacts: sudbury lakes revisited
(Wiley, 2022-05-16)Mining and smelting activities have strongly influenced the Sudbury region (Ontario, Canada) since the late 19th century, leading to acidification and metal contamination in many local ecosystems. Regulations on restricting ... -
Expression and characterization of an antifreeze protein from the perennial rye grass, Lolium perenne
(Elsevier, 2011-06)Antifreeze proteins (AFP) are an evolutionarily diverse class of stress response products best known in certain metazoans that adopt a freeze-avoidance survival strategy. The perennial ryegrass, Lolium perenne (Lp), cannot ... -
Using Diatoms to Track Road Salt Seepage into Small, Shallow, Softwater Ontario Lakes
(Canadian Science Publishing, 2022-04-04)Since the 1950s, the widespread application of road salt for winter road maintenance and safety in cold regions has led to increased conductivity levels in many freshwater systems. Salting practices have adversely affected ... -
Using Stable Water Isotope Composition (δ¹⁸O and δ²H) to Track the Interannual Responses of Arctic and Tropical Andean Water Bodies to Rising Air Temperatures
(Wiley, 2022-04-06)Lakes in the Arctic and tropical Andes are experiencing some of the largest temperature increases on the planet with coeval marked limnological changes, but little data exist on water balance parameters from these regions. ... -
Climate Oscillations Drive Millennial-Scale Changes in Seabird Colony Size
(Wiley, 2022-03-23)Seabird population size is intimately linked to the physical, chemical, and biological processes of the oceans. Yet, the overall effects of long-term changes in ocean dynamics on seabird colonies are difficult to quantify. ... -
Life under an oil slick: response of a freshwater food web to simulated spills of diluted bitumen in field mesocosms
(Canadian Science Publishing, 2020-02-17)Heavy crude oil transportation over land is increasing, yet the ecological impacts of spills, particularly of diluted bitumen, in freshwater environments remain poorly understood. We simulated spills of diluted bitumen in ... -
The Great Auk (Pinguinus impennis) had two brood patches, not one: confirmation and implications
(Wiley, 2021-09-21)Since the late 1600s it has been assumed that the Great Auk Pinguinus impennis was similar to the Common Guillemot Uria aalge and Brünnich’s Guillemot U. lomvia in having a single, central brood patch. Through the examination ... -
Maternal effects on embryonic development and survival in walleye of Lake Nipissing, Ontario
(American Fisheries Society, 2021-08-17)Life history theory predicts that females may increase reproductive allocation with advancing age as the probability for future reproduction diminishes. In iteroparous fishes, increasing age is usually accompanied by ... -
Lake and Stream Fishes: Ecology, Adaptation, Diets and Resource Use
(11/24/2020)This text has as its objective a synthesis of the ecology and biogeography of small lake fish systems, as illustrated by the North American fauna and, specifically, the cool temperate one of the northeast of the continent. ... -
The Importance of Live‐Well Transport in the Physiological Disturbance Experienced by Smallmouth Bass in Tournaments on Large Water Bodies
(Wiley, 2019)Competitive fishing has become an important element of recreational fisheries for black bass Micropterus spp. in North America. The vast majority of competitive events involve a “live‐release” format, where fish are held ... -
Breeding eider ducks strongly influence subarctic coastal pond chemistry
(2018)Arctic freshwater ponds are typically pristine and oligotrophic, however, seabird biovectors can markedly alter 29 water quality via enrichment with marine-derived nutrients and bioaccumulated metals. These ornithogenic ... -
Interannual variation in season length is linked to strong co-gradient plasticity of phenology in a montane annual plant
(Wiley, 2019-06-21)Species are commonly distributed along latitudinal and elevational gradients of growing season length to which they might respond via phenotypic plasticity and / or adaptive genetic differentiation. However, the relative ... -
Transcriptional and post-translational upregulation of phosphoenolpyruvate carboxylase in Arabidopsis thaliana (L. Heynh) under cadmium stress
(Elsevier, 2019-08-01)Phosphoenolpyruvate carboxylase (PEPC) is a tightly controlled anaplerotic enzyme that replenishes organic acids that have been withdrawn from the tricarboxylic acid cycle. Organic acid anions are important chelators of ... -
EDTP/MTMR14: A novel target for improved survivorship to prolonged anoxia and cellular protein aggregates
(Elsevier, 2019-07-13)Drosophila egg-derived tyrosine phosphatase (EDTP), a lipid phosphatase that removes 3-position phosphate at the inositol ring, has dual functions in oogenesis and muscle performance in adults. A mammalian homologous gene ...
