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 ... -
Rapid cold hardening and octopamine modulate chill tolerance in Locusta migratoria
(Elsevier, 2019-08-01)Temperature has profound effects on the neural function and behaviour of insects. When exposed to low temperature, chill-susceptible insects enter chill coma, a reversible state of neuromuscular paralysis. Despite the ... -
Extra-pair offspring are less heterozygous than within-pair offspring in American redstarts (Setophaga ruticilla)
(2019-03-20)The vast majority of bird species are socially monogamous; however, extra-pair paternity is nearly ubiquitous and a number of theories have been proposed to explain the prevalence of this mixed mating strategy. Here, we ... -
Correlates of alternative migratory strategies in western bluebirds
(2019-03-08)Partial migration occurs when only some animals in a population migrate. While evidence suggests that migratory strategies are partially controlled by genes, individual and environmental conditions which alter the cost-benefit ...
