2004
Populations of a host species may exhibit different assemblages of parasites and other symbionts. The loss of certain species of symbionts (lineage sorting, or ‘‘missing-the-boat’’) is a mechanism by which geographical variation in symbiont assemblages can arise. We studied feather mites and lice...

Interactions Between Host Trees, Bacteria, and Fungi: Impacts on Mountain Pine Beetle (Dendroctonus ponderosae) Reproduction
DownloadFall 2012
Warming winter trends due to climate change have allowed for a range expansion of the mountain pine beetle, and the beetle now threatens Canada’s economically and ecologically important jack pine forests. The beetle’s success in jack pine trees will depend upon successful colonization of the...

Intrinsic rate of increase and temperature coefficients of the aphid parasite Ephedrus californicus baker (Hymenoptera: Aphidiidae)
Download1987
The demographic statistics and the temperature requirements for development of Ephedrus californicus Baker were determined under constant laboratory conditions. At 23°C, females provided each day with forty 2nd-instar pea aphids, Acyrthosiphon pisum (Harris), lived for 13.4 days and laid 1193...

Abstract: During a survey of microfungi from rotting wood in northern Alberta forests, 49 species of ascomycetes, representing 24 genera, and 15 families in seven orders, were recovered. Twenty-eight species are new reports for Alberta, 15 of which are new for Canada, and seven are new for North...

Multilocus species identification and fungal DNA barcoding: insights from blue stain fungal symbionts of the mountain pine beetle
Download2020-01-08
Roe, Amanda, Rice, Adrianne, Bromilow, Sean, Cooke, Janice, Sperling, Felix
There is strong community-wide interest in applying molecular techniques to fungal species delimitation and identification, but selection of a standardized region or regions of the genome has not been finalized. A single marker, the ribosomal DNA internal transcribed spacer region, has frequently...

Native tree seedling interactions with variations in edaphic properties in upland boreal forest restoration
DownloadSpring 2015
The boreal forest is a vast circumpolar ecosystem covering approximately 11 % of terrestrial land globally. The Canadian boreal forest is rich in natural resources such as lumber, minerals, and oil, and therefore is heavily managed by humans in some regions. Surface mining for oil sands deposits...

Next-Generation Sequencing of Protists as a Measure of Natural Soil Microbial Eukaryotic Community in the Oil Sands Region

Quideau, S., Richardson, E., Dacks, J.B., MacIntyre, G., Adl, S., Walker, G.
Soil plays a central role in the functioning of all terrestrial ecosystems. Among the many ecosystem services to which soil contributes are: purification and storage of water, sequestration of organic matter, nutrient cycling for plant growth, and conservation of healthy faunal and microbial...

Phoretic mite associates of mountain pine beetle at the leading edge of an infestation in northwestern Alberta, Canada
Download2011
Proctor, H. C., Evenden, M. L., Mori, B. A., Walter, D. E.
Abstract: We identified species of mites phoretically associated with mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), collected from bolts of lodgepole pine, Pinus contorta Douglas ex Louden (Pinaceae), and pheromone-baited traps in northwestern...

Shape Variation of Cysticercoids of Hymenolepis diminuta (Cyclophyllidea) from Fed, Partially Fed, and Fasted Tribolium confusum (Coleoptera)
Download2006
Quantitative studies of a crowding effect on cysticercoids of Hymenolepis diminuta in the intermediate host are few and limited in scope. In this study, we developed a technique to rapidly collect morphological information on large numbers of parasites, and verified the utility of geometric...

Spatial genetic structure of a symbiotic beetle-fungal system: Toward multi-taxa integrated landscape genetics
Download2011-01-01
Sperling, Felix A. H., Hamelin, Richard C., Murray, Brent W., James, Patrick M. A., Coltman, Dave W.
Spatial patterns of genetic variation in interacting species can identify shared features that are important to gene flow and can elucidate co-evolutionary relationships. We assessed concordance in spatial genetic variation between the mountain pine beetle (Dendroctonus ponderosae) and one of its...
