    J L Fitzpatrick
    Department of Biology, McMaster University, Hamilton, Ontario, Canada L8S 4K1
    Biol Reprod 77:280-4. 2007
    ..Interestingly, we were unable to detect any variation in sperm tail length among these reproductive tactics. Thus, sperm competition appears to have influenced sperm energetics in this species without having any influence on sperm size...
  2. pmc Female-mediated causes and consequences of status change in a social fish
    J L Fitzpatrick
    Department of Biology, McMaster University, Hamilton, Ont, Canada L8S 4K1
    Proc Biol Sci 275:929-36. 2008
    ..These results highlight the complex interactions between social status, reproductive physiology and group dynamics, and underscore a convergent pattern of reproductive investment among highly social, cooperative species...
  3. doi The relative sensitivity of sperm, eggs and embryos to copper in the blue mussel (Mytilus trossulus)
    J L Fitzpatrick
    Department of Biology, McMaster University, Hamilton, Ontario, Canada L8S 4K1
    Comp Biochem Physiol C Toxicol Pharmacol 147:441-9. 2008
    ..Based on our results, we suggest that exposure of sperm to copper may interfere with mitochondrial activity, which reduces sperm swimming speed during the extended duration of sperm motility in blue mussel...

    N M Sopinka
    Animal Behaviour Group, Department of Psychology, Neuroscience and Behaviour, McMaster University, 1280 Main St West, Hamilton, ON, L8S 4K1 Canada
    J Fish Biol 80:2374-83. 2012
    ..The results of this study provide important insights into the potential consequences of contaminant exposure on the reproductive physiology of wild-caught fishes...

    K A Stiver
    Department of Psychology, McMaster University, Hamilton, Ontario, Canada, L8S 4K1
    Mol Ecol 16:2974-84. 2007
    ..Our results highlight the importance of examining multiple spatial scales when studying individual dispersal biases...

    N M Sopinka

    J Fish Biol 75:1-16. 2009
    ..Hence, these results contrast with previous liver studies and suggest that liver investment patterns were linked to status-driven differences in energy expenditure but not to energy intake or storage in N. pulcher...

    E S Swai
    Veterinary Investigation Centre, Arusha, Tanzania
    Trop Anim Health Prod 37:513-25. 2005
    ..Dystocia, RFM, poor condition score and mineral deficiency were common problems and were possibly linked to LCI...

    R G O'Neill
    University of Glasgow Veterinary School, Glasgow G61 1QH, UK
    Vaccine 24:4007-16. 2006
    ..There was no evidence for interbreed differences between Holstein and Charolais calves, post-vaccination. These results suggest that calf-sire has a major heritable influence on serum IgG levels following BRSV immunisation...
