Current status of invasive alien birch-leafmining sawflies (Hymenoptera: Tenthredinidae) in Canada, with keys to species
Download2009
MacQuarrie, C. J. K., Nystrom, K. L., Langor, D. W., Digweed, S. C., Williams, D. J. M., Morneau, L., Spence, J. R.
Abstract: In the 20th century, five species of birch-leafmining sawflies were inadvertently introduced from Europe to North America: Heterarthrus nemoratus (Fallen), Fenusa pumila Leach, Profenusa thomsoni (Konow), Fenusella nana (Klug), and Scolioneura vicina Konow. All have been recorded at...

Macdonald, S. Ellen, Islam, M. Anisul
We investigated the effects of flooding for three weeks on physiological responses and uptake of NH4+ and NO3- by black spruce (Picea mariana (Mill.) BSP.) and tamarack (Larix laricina (Du Roi) K. Koch) seedlings fertilized with labeled (15NH4)2SO4 or K15NO3 in a growth chamber experiment....

Cuticular plasticization in the tick, Amblyomma hebraeum (Acari: Ixodidae): possible roles of monoamines and cuticular pH
Download2010
Reynolds, S. E., Flynn, P. C., Kaufman, W. R.
Abstract: The degree of plasticization of the alloscutal cuticle of a 'hard' (ixodid) tick, Amblyomma hebraeum, and a 'soft' (argasid) tick, Ornithodoros moubata, was assessed throughout the blood-feeding period. Cuticle viscosity was calculated from rate of creep of cuticle under constant load...
