Acid-base properties of cyanobacterial surfaces I: Influences of growth phase and nitrogen metabolism on cell surface reactivity
Download2008
Konhauser, K.O., Owttrim, G.W., Smith, D.S., Lalonde, S.V.
Significant efforts have been made to elucidate the chemical properties of bacterial surfaces for the purposes of refining surface complexation models that can account for their metal sorptive behavior under diverse conditions. However, the influence of culturing conditions on surface chemical...

Acid-base properties of cyanobacterial surfaces II: Silica as a chemical stressor influencing cell surface reactivity
Download2008
Owttrim, G.W., Lalonde, S.V., Smith, D.S., Konhauser, K.O.
Bacteria grow in complex solutions where the adsorption of aqueous species and nucleation of mineral phases on the cell surface may interfere with membrane-dependent homeostatic functions. While previous investigations have provided evidence that bacteria may alter their surface chemical...

Alternative Requirements for Vestigial, Scalloped, and Dmef2 during Muscle Differentiation in Drosophila melanogaster
Download2009
Bell, J. B., Deng, H., Simmonds, A. J., Hughes, S. C.
Abstract: Vertebrate development requires the activity of the myocyte enhancer factor 2 (mef2) gene family for muscle cell specification and subsequent differentiation. Additionally, several muscle-specific functions of MEF2 family proteins require binding additional cofactors including members...

Autoregulation of RNA helicase expression in response to temperature stress in Synechocystis spCC 6803
Download2012
Owttrim, George W., Chamot, Danuta, Rosana, Albert R. R.
RNA helicases are ubiquitous enzymes whose modification of RNA secondary structure is known to regulate RNA function. The pathways controlling RNA helicase expression, however, have not been well characterized. Expression of the cyanobacterial RNA helicase, crhR, is regulated in response to...

Longrich, N. R., Currie, P. J., Erickson, G. M., Horner, J. R.
Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. Methodology/Principal Findings: Examination...

Climbing simulated vegetation to heights of ungulate hosts by larvae of Dermacentor albipictus (Acari: Ixodidae)
Download2000
Samuel, W. M., Shostak, A. W., McPherson, M.
Abstract: Larvae of winter ticks, Dermacentor albipictus (Packard), ascend vegetation in autumn and form clumps that attach to passing ungulate hosts. We tested the hypothesis that vegetation height determines the height of clumps. During the vegetation-to-ungulate transmission period (early...

Different scales of spatial segregation of two species of feather mites on the wings of a passerine bird
Download2011
Mestre, A., Mesquita-Joanes, F., Proctor, H., Monros, J. S.
The \"condition-specific competition hypothesis\" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their...

Disentangling detoxification: Gene expression analysis of feeding mountain pine beetle illuminates molecular-level host chemical defense detoxification mechanisms
Download2013-01-01
Bohlmann, Jörg, Bonnett, Tiffany R., Pitt, Caitlin, Keeling, Christopher I., Yuen, Macaire M. S., Huber, Dezene P. W., Robert, Jeanne A.
The mountain pine beetle, Dendroctonus ponderosae, is a native species of bark beetle (Coleoptera: Curculionidae) that caused unprecedented damage to the pine forests of British Columbia and other parts of western North America and is currently expanding its range into the boreal forests of...

Fecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
Download2004
Karels, T. J., Koppel, L., Hik, D. S.
We evaluated fecal pellet counts as an index of hoary marmot (Marmota caligata) social group size in order to develop a simple, inexpensive method for monitoring population change of a widely distributed, but poorly studied alpine mammal. Fecal pellet counts were conducted in three separate...
