Studies on beetle/tree fungal symbionts typically characterize the ecological and geographic distributions of the fungal populations. There is limited understanding of the genome-wide evolutionary processes that act within and between species as such fungi adapt to different environments, leading...

Comparative Morphology and Phylogenetic Placement of Two Microsclerotial Black Fungi from Sphagnum
Download2003
Currah, R.S., Hambleton, S., Tsuneda, A.
Capnobotryella renispora and Scleroconidioma sphagnicola form black, irregularly shaped microsclerotia that are indistinguishable in gross morphology on leaves of Sphagnum fuscum. In culture, microsclerotia of these fungi were similar, in that mature component cells possessed thick, highly...

Comparative phylogeography, genetic differentiation, and contrasting reproductive modes in three fungal symbionts of a multipartite bark beetle symbiosis

Roe, Amanda, Rice, Adrianne, Coltman, David, Cooke, Janice, Sperling, Felix
Grosmannia clavigera is a fungal pathogen of pine forests in western North America and a symbiotic associate of two sister bark beetles: Dendroctonus ponderosae and D. jeffreyi. This fungus and its beetle associate D. ponderosae are expanding in large epidemics in western North America. Using the...

Comparison of lodgepole and jack pine constitutive and induced resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae, (Coleoptera: Curculionidae)

Clark, Erin L., Carroll, Allan L., Huber, Dezene P.W., Lindgren, B. Staffan, Pitt, Caitlin
The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC), where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the...

Comparison of serum antibody responses to Giardia lamblia of symptomatic and asymptomatic patients
Download1998
Belosevic, M., El-Mageid, S.A., Handousa, A.A., Hegazi, M.M., Abou-Shady, A.F., Soliman, M.M., Taghi-Kilani, R.
The circulating anti-parasite antibody response against Giardia lamblia in symptomatic and asymptomatic Egyptian children with confirmed giardiasis was examined. Symptomatic patients were identified using the following criteria: presence of only G. lamblia cysts in the feces, and one or more of...

Eftimie, R., De Vries, G., Lewis, Mark A.
We present previously undescribed spatial group patterns that emerge in a one-dimensional hyperbolic model for animal group formation and movement. The patterns result from the assumption that the interactions governing movement depend not only on distance between conspecifics, but also on how...

Comprehensive transcriptional profiling of NaCl-stressed Arabidopsis roots reveals novel classes of responsive genes
Download2006
Background: Roots are an attractive system for genomic and post-genomic studies of NaCl responses, due to their primary importance to agriculture, and because of their relative structural and biochemical simplicity. Excellent genomic resources have been established for the study of Arabidopsis...

Computational identification of residues that modulate voltage sensitivity of voltage-gated potassium channels
Download2005
Background: Studies of the structure-function relationship in proteins for which no 3D structure is available are often based on inspection of multiple sequence alignments. Many functionally important residues of proteins can be identified because they are conserved during evolution. However,...
