    Selenium (Se), an essential element, can bioaccumulate and become toxic. The main toxicity symptom in fish, teratogenicity, is mediated by oxidative stress; however, little is known about the effect of Se on the physiological ...
  • Dann, Andrea B (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2011Arts and ScienceDepartment of Biological Sciences, 2011)
    The ubiquitous presence of anthropogenic chemicals and their transformation products in surface water represents a toxicological concern from both an ecological standpoint and a human perspective as many of these chemicals ...

    Endocrine disrupting compounds and pesticides have been detected in rivers and irrigation canals of Southern Alberta, a semiarid region with irrigation-dependent crop production, intensive livestock operations, and a ...

    Fish are exposed to multiple stressors in their environment. The interactive effects of pesticide exposure and increased temperature on the physiological stress response were investigated in a comparative field study ...
  • Pilgrim, Nicole L (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2012Arts and ScienceBiological Sciences Department, 2012)
    Selenium (Se) is an essential element, toxic at concentrations only slightly above those required. It can become detrimental to fish health when available in excess in the aquatic environment. This study examined the effects ...
  • Miller, Lana L; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Biological Sciences, c2011Arts and ScienceDepartment of Biological Sciences, 2011)
    Model organisms are often used in ecotoxicological studies and environmental risk assessments; however, species differences in responses to toxicants exist. A meta-analysis identified normal biomarker ranges for rainbow ...
