Tracing an Invasion : Phylogeography of Cactoblastis cactorum ( Lepidoptera : Pyralidae ) in the United States Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Simonsen, T. J., Brown, R. L.
Abstract: The adventive cactus moth Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), a widely used biological control agent for Opuntia Mill. cacti, was detected in Florida in 1989. Since then, it has spread along the Atlantic and Gulf Coasts of southeastern United States, threatening...

Trade-offs between predation risk and forage differ between migrant strategies in a migratory ungulate
Download2009
Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an \"escape'' from predation, but trade-offs can also occur at finer spatial scales. Previous...

Transcriptional profiling of pea ABR17 mediated changes in gene expression in Arabidopsis thaliana
Download2008
Srivastava, S., Deyholos, M.K., Kav, N.N.V., Krishnaswamy, S.S., Mohammadi, M., Rahman, M.
Background: Pathogenesis-related proteins belonging to group 10 (PR10) are elevated in response to biotic and abiotic stresses in plants. Previously, we have shown a drastic salinityinduced increase in the levels of ABR17, a member of the PR10 family, in pea. Furthermore, we have also...

Transcriptome resources and functional characterization of monoterpene synthases for two host species of the mountain pine beetle, lodgepole pine (Pinus contorta) and jack pine (Pinus banksiana)

Hall, Dawn E., Arango-Velez, Adriana, Dullat, Harpreet K., Keeling, Christopher I., Breuil, Colette, Liao, Nancy Y., Henderson, Hannah, Bohlmann, Jörg, Cooke, Janice E. K., Quesada, Alfonso L., Jones, Steven J. M., Chan, Simon K., Jancsik, Sharon, Docking, Roderick T., Li, Maria, Yuen, Macaire M. S.
Background The mountain pine beetle (MPB, Dendroctonus ponderosae) epidemic has affected lodgepole pine (Pinus contorta) across an area of more than 18 million hectares of pine forests in western Canada, and is a threat to the boreal jack pine (Pinus banksiana) forest. Defence of pines against...

Cyanobacterial (CB) blooms are becoming a global concern due to the increasing prevalence of eutrophication. The dependence of CB dynamics on phosphorus and light inputs is modeled via a stoichiometric approach. The dynamics occur in distinct phases that allow us to make use of multiple timescale...

Trawetsia princetonensis gen. et sp. nov. (Blechnaceae): a permineralized fern from the Middle Eocene Princeton Chert
Download2006
Rothwell, G.W., Stockey, R.A., Nishida, H., Smith, S.Y.
Trawetsia princetonensis Smith, Stockey, Nishida & Rothwell gen. et sp. nov. is described from several permineralized rhizomes, stipes, and higher-order frond members of a blechnoid fern that have been identified from the Middle Eocene Princeton Chert of British Columbia. Rhizomes bear stipes...

TreeFam is a database of phylogenetic trees of gene families found in animals. It aims to develop a curated resource that presents the accurate evolutionary history of all animal gene families, as well as reliable ortholog and paralog assignments. Curated families are being added progressively,...

Triage for conserving populations of threatened species: The case of woodland caribou in Alberta.
Download2010
Hauer, G., Adarnowicz, W., Boutin, S., Schneider, R.
Prioritization of conservation efforts for threatened and endangered species has tended to focus on factors measuring the risk of extirpation rather than the probability of success and cost. Approaches such as triage are advisable when three main conditions are present: insufficient capacity...

Khan, Amanda S., Chu, Jackson W. F., Leys, Sally P.
Sponges link the microbial loop with benthic communities by feeding on bacteria. Glass sponge reefs on the continental shelf of western Canada have extremely high grazing rates, consuming seven times more particulate carbon than can be supplied by vertical flux alone. Unlike many sponges, the...

Trophic Relations of the Red-Necked Grebe on Lakes in the Western Boreal Forest: A Stable-Isotope Analysis.
Download2004
Tonn, W. M., Klatt, P. H., Paszkowski, C. A., Gingras, B. A., Wilcox, K.
We compared trophic ecology of grebes inferred from stable-isotope analysis to that from gut contents, and compared isotopic ratios of Red-necked Grebes (Podiceps grisegena) from lakes differing in their food webs. Analyses of different grebe tissues (egg yolk and albumen, pectoral and leg...
