Accumulation of Al in Root Mucilage of an Al-Resistant and an Al-Sensitive Cultivar of Wheat
Download1996
Archambault, D. J., Zhang, G., Taylor, G. J.
To estimate rates of Al accumulation within the symplasm, all apoplastic pools of Al need to be eliminated or accounted for. We have developed a revised kinetic protocol that allows us to estimate the contribution of mucilage-bound Al to total, nonexchangeable Al, and to eliminate the mucilage as...

Achieving Conservation when Opportunity Costs Are High: Optimizing Reserve Design in Alberta’s Oil Sands Region
Download2011-08-17
Using Alberta, Canada, as a case study we use a trade-off analysis to systematically explore the relationship between conservation targets and economic opportunity costs in the context of coarse-filter reserve design. We use the Marxan conservation planning software to generate reserve designs at...

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...

Acrocerid (Insecta, Diptera) Life-Histories, Behaviors, Host Spiders (Arachnida, Araneida), and Distribution Records
Download1993
Stratton, G., Sorkin, L., Leech, R., Cady, A., Caldwell, M.
Abstract: The family Acroceridae (Insecta: Diptera; ''Small Headed Flies'') are a seldom seen yet cosmopolitan group of endoparasitoids of spiders. Recent host and distribution records are presented here for six species of acrocerids: Ogcodes borealis Cole, 1919; Ogcodes pallidipennis (Loew,...

Activity of flour beetles (Tribolium confusum) in the presence of feces from rats infected with rat tapeworm (Hymenolepis diminuta)
Download1998
We studied the attraction of flour beetles (Tribolium confusum) to feces from rats infected with the rat tapeworm, Hymenolepis diminuta. Beetles were either fed or fasted prior to each trial. During trials, beetles were tested. singly or in groups and offered a choice (i) between natural baits...

Adaptations to Submarine Hydrothermal Environments Exemplified by the Genome of Nautilia profundicola
Download2009
Hanson, T.E., Cary, S.C., Eisen, J.A., Stein, L.Y., Robinson, J.M., Campbell, B.J., Lee, C.K., Wu, D., Smith, J.L., Khouri, H.M., Klotz, M.G.
Submarine hydrothermal vents are model systems for the Archaean Earth environment, and some sites maintain conditions that may have favored the formation and evolution of cellular life. Vents are typified by rapid fluctuations in temperature and redox potential that impose a strong selective...

Adaptive and neutral markers both show continent-wide population structure of mountain pine beetle (Dendroctonus ponderosae)
Download2016-01-01
Sperling, Felix A. H., Murray, Brent W., Batista, Philip D., Janes, Jasmine K., Boone, Celia K.
Assessments of population genetic structure and demographic history have traditionally been based on neutral markers while explicitly excluding adaptive markers. In this study, we compared the utility of putatively adaptive and neutral single-nucleotide polymorphisms (SNPs) for inferring mountain...

1999
We observed a case of adoption of a single four-month-old polar bear cub (Ursus maritimus) into an existing litter of two cubs on Hopen Island, Svalbard. We believe the high density of maternity dens in the study area may increase the likelihood of natural adoption. Speculation about theoretical...
