Skaare, J.U., Wiig, Ø., Haave, M., Dahl, E., Lie, E., Ropstad, E., Derocher, A.E.
High concentrations of polychlorinated biphenyls (PCBs) in polar bears from Svalbard have increased concern for that population’s reproductive health. We examined whether there were associations between the plasma concentrations of PCBs and reproductive hormones [progesterone (P4) and...

PolySearch: A web-based text mining system for extracting relationships between human diseases, genes, mutations, drugs and metabolites
Download2008
Stothard, P., Damaraju, S., Wishart, D.S., Young, N., Cheng, D., Knox, C.
A particular challenge in biomedical text mining is to find ways of handling ‘comprehensive’ or ‘associative’ queries such as ‘Find all genes associated with breast cancer’. Given that many queries in genomics, proteomics or metabolomics involve these kind of comprehensive searches we believe...

Yu Jin, Qihua Huang, Julia Blackburn, Mark A. Lewis
The study of population persistence in river ecosystems is key for understanding population dynamics, invasions, and instream flow needs. In this paper, we extend theories of persistence measures for population models in one-dimensional rivers to a benthic-drift model in two-dimensional...

Population Structure and Gene Flow in the White Pine Weevil, Pissodes strobi (Coleoptera: Curculionidae)
Download2004
Sperling, F. A. H., Laffin, R. D., Langor, D. W.
Abstract: The white pine weevil, Pissodes strobi (Peck), is a major source of damage to young spruce and pine trees across North America. The species contains a substantial amount of genetic, morphological, and behavioral variation, and identification of patterns of genetic variation on a broad...

Population structure and phylogenetic relationships of Ceutorhynchus neglectus (Coleoptera: Curculionidae)
Download2005
Sperling, F. A. H., Dosdall, L. M., Laffin, R. D.
Ceutorhynchus neglectus Blatchley is a weevil that is native to, and widely distributed in, North America. It has life-history characteristics similar to its alien invasive congener, Ceutorhynchus obstrictus (Marsham), the cabbage seedpod weevil. Our study was undertaken to compare the population...

Population Structure of Mountain Pine Beetle Symbiont Leptographium longiclavatum and the Implication on the Multipartite Beetle-Fungi Relationships
Download2014-01-01
Roe, Amanda D., Farfan, Lina, Cooke, Janice E. K., Hamelin, Richard C., El-Kassaby, Yousry A., Rice, Adrianne V., Tsui, Clement K.
Over 18 million ha of forests have been destroyed in the past decade in Canada by the mountain pine beetle (MPB) and its fungal symbionts. Understanding their population dynamics is critical to improving modeling of beetle epidemics and providing potential clues to predict population expansion....

Environmental variation is often a very important aspect in the ecology of organisms, with most populations experiencing at least seasonal fluctuations in resource availability and thus in their carrying capacity (Annegers 1973; Emmel 1976, chap. 10; Fleming and Hooker 1975; Fretwell 1972). A...

Population-level Responses to Nutrient Heterogeneity and Density by Abutilon Theophrasti (Malvaceae): An Experimental Neigborhood Approach
Download1998-01-01
An experimental approach was used to examine the effects of spatial nutrient heterogeneity and planting density on the sizes of plants within populations of Abutilon theophrasti. Planting locations were generated using random numbers and replicated among populations growing on two different...
