Pachepsky, E., Lewis, Mark A., Lutscher, F.
Individuals in streams are constantly subject to predominantly unidirectional flow. The question of how these populations can persist in upper stream reaches is known as the “drift paradox.” We employ a general mechanistic movement-model framework and derive dispersal kernels for this situation....

The effect of sex, size and habitat on the incidence of puncture wounds in the claws of the porcelain crab Petrolisthes cinctipes (Anomura: Porcellanidae)
Download2007
Many porcelain crabs have an unusual claw (cheliped) form that is broad, flat and thin. This seemingly flimsy form suggests claws may be used more for display than for feeding or aggressive interactions. However, in the flat-topped porcelain crab Petrolisthes cinctipes, one of the most abundant...

The effect of water limitation on tree defense and host suitability of lodgepole and jack pine for Dendroctonus ponderosae
Download2016
Lusebrink, Inka, Erbilgin, Nadir, Maya L. & Evenden,
The mountain pine beetle (MPB; Dendroctonus ponderosae) has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response...

The endosymbiont Wolbachia pipientis induces the expression of host antioxidant proteins in an Aedes albopictus cell line
Download2008
Harris, H.L., Brennan, L.J., Keddie, B.A., Braig, H.R.
Wolbachia are obligate intracellular bacteria which commonly infect arthropods. They are maternally inherited and capable of altering host development, sex determination, and reproduction. Reproductive manipulations include feminization, male-killing, parthenogenesis, and cytoplasmic...

In eukaryotes, protein deacetylation is carried out by two well-conserved histone deacetylase (HDAC) families: RPD3/HDA1 and SIR2. Intriguingly, model plants such as Arabidopsis express an additional plant-specific HDAC family, termed type-2 HDACs (HD2s). Transcriptomic analyses from more than...

Lepage, B. A., Currah, R. S., Stockey, R. A.
The middle Eocene Princeton chert locality in southern British Columbia, Canada, contains one of the best-preserved permineralized Tertiary floral assemblages known in North America. The quality of pres- ervation of the vascular plant and fungal remains is exquisite because anatomical and...

Rothwell, Gar W., Stockey, Ruth A., Hoffman, Georgia L.
More than 200 specimens of Limnobiophyllum scutatum (Dawson) Krassilov have been recovered from lacustrine claystones in the Paleocene Paskapoo Formation near Red Deer, Alberta. The plant was a floating, aquatic angiosperm with helically arranged, ovate leaves attached in small rosettes. Rosettes...
