Chemoreception in invasive rusty crayfish (Orconectes rusticus): learning and adaptation in aquatic ecosystems of Northwestern Ontario
(2012-11-10)Crayfish utilize chemosensory cues, in addition to other sensory inputs, to mediate a variety of fundamental life processes. Exotic species, like the rusty crayfish (Orconectes rusticus), are known to employ a broader ... -
The effects of copper, calcium, and nickel on the olfactory response of fathead minnows: from neurophysiology to behaviour
(2014-01-22)The olfactory system is essential for a fish to be successful in an ecological context, and has been demonstrated to be sensitive to a variety of toxicants. The current biotic ligand model (BLM) for copper is an acute-toxicity ... -
Intra-lake and inter-lake variation in copper tolerance in Daphnia from clean and metal-contaminated lakes
(2014-01-22)The freshwater invertebrate Daphnia can persist in historically metal-contaminated lakes due to its ability to adapt to metal contamination. Since different Daphnia isolates have been shown to have varying degrees of ... -
Investigation into the ecological costs of sea lamprey control on lake sturgeon and ammocoete predators using olfactory techniques
(2015)Fish that feed or travel in low light conditions particularly rely on their chemical senses, such as olfaction, for survival. Exposure to toxicants at concentrations lower than those causing mortality can have detrimental ... -
Lake trout and their egg predators' ability to locate spawning substrate using olfaction
(2014-01-22)Lake trout spawning sites, and the substrate on these sites, are structurally unique in many ways. These sites are generally at the end of the fetch of a lake, close to shore (1 m) and composed of small to medium sized ... -
Metal induced olfactory impairment in fish: gene expression, protection and recovery
(2014)To play their ecological role in an ecosystem, a fully functioning olfactory system is vital for fishes. A fish's olfactory system is very sensitive to low concentrations of contaminants. A great deal of research has ... -
Mixtures of Metals and Polycyclic Aromatic Hydrocarbons Lead to Complex Toxic Outcomes in the Freshwater Amphipod, Hyalella azteca
(2015)The study of ecotoxicology inevitably must address the fact that toxicants always occur in mixture. Unfortunately, our present state of knowledge in terms of predicting the effects of contaminant mixtures and understanding ... -
Testing local adaptation in five populations of Hyalella azteca in northern Alberta’s oil sands region
(2015)Canada’s oil sands hold the third largest petroleum reserves worldwide. Rapid economic growth has led to increased exploitation of the surrounding boreal forest despite limited understanding of the environmental effects ...
