Effects of acanthocephalan parasites on colour and carotenoid quantities of their intermediate host Gammarus lacustris in the context of variable lake productivity
DownloadFall 2010
I studied the effects of Polymorphus paradoxus Connell and Corner and Polymorphus marilis Van Cleave on colour and carotenoid quantities of their host amphipod Gammarus lacustris G.O. Sars in seven lakes in Alberta, Canada, that differed in productivity. Polymorphus marilis induced ‘pigmentation...

Effects of crop rotation and genetically modified herbicide-tolerant corn on ground beetle diversity, community structure and activity density
Download2010
Spence, J.R., Floate, K., Blackshaw, R.E., Bourassa, S., Carcamo, H.A.
Ground beetles (Coleoptera. Carabidae) were sampled in conventional and genetically modified herbicide-tolerant (GM HT) corn, Zea mays L. (Poaceae), planted under rotation with canola, Brassica L. (Brassicaceae), or continuously cropped corn to investigate the influence of corn variety and...

Effects of natural gas development on three grassland bird species in CFB Suffield, Alberta, Canada
DownloadSpring 2010
I investigated the effect of energy sector development and introduced crested wheatgrass (Agropyron cristatum) on grassland birds on Canadian Forces Base Suffield. I conducted point counts and mapped breeding territories in 2007 and 2008 for Savannah sparrows (Passerculus sandwichensis),...

Sphingomyelin (SM), a sphingolipid that is concentrated in the extracellular leaflet of the plasma membrane, can interact with cholesterol to form more ordered “raft” domains. The hydrolysis of SM by sphingomyelinase (SMase) generates ceramide and may redistribute cholesterol molecules to other...
