Background The Antarctic krill Euphausia superba is a keystone species in the Antarctic food chain. Not only is it a significant grazer of phytoplankton, but it is also a major food item for charismatic megafauna such as whales and seals and an important Southern Ocean fisheries crop. Ecological...

Land management practices are known to influence runoff through alteration of the antecedent soil water For accurate estimation of runoff, direct measurement of antecedent soil water would be necessary. This study investigated antecedent soil water and the potential for summer storm runoff under...

Andersson, Martin N., Schlyter, Fredrik, Bohlmann, Jörg, Grosse-Wilde, Ewald, Li, Maria, Keeling, Christopher I., Hansson, Bill S., Bengtsson, Jonas M., Yuen, Macaire M.S., Hillbur, Ylva
Background The European spruce bark beetle, Ips typographus, and the North American mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae: Scolytinae), are severe pests of coniferous forests. Both bark beetle species utilize aggregation pheromones to coordinate mass-attacks on...

Limestone quarry reclamation worldwide requires development of substrates or anthroposolic soils. The suitability of three limestone substrates (gray, gray brown, crushed) for revegetation was assessed in two greenhouse experiments. In the first experiment amended substrates (pulp mill sludge,...

In a two-stimulus visual discrimination choice task with a reversal in reward contingencies midway through each session, pigeons produce a surprising number of anticipatory errors (i.e., responding to the second-correct stimulus before the reversal) based on failure to inhibit timing-based...

Antibodies confer humoral immunity but can also be harmful when they target an autoantigen, alloantigen, allergen, or biotherapeutic. New strategies are needed for antigen-specific suppression of undesired antibody responses, particularly to T cell–dependent protein antigens, because they elicit...

Antimicrobial activity in the egg wax of the African cattle tick Amblyomma hebraeum (Acari: Ixodidae)
Download2006
Arrieta, M. C., Leskiw, B. K., Kaufman, W. R.
Abstract: Eggs of the tick Amblyomma hebraeum Koch (Acari: Ixodidae) inhibited the growth of Escherichia coli and Serratia marcescens (Gram-negative bacteria) in solid culture, but not the growth of Staphylococcus epidermidis, and only marginally the growth of Bacillus subtilis (Gram-positive...

Yu, Z., Liu, J., Kaufman, W. R., Thomson, E. L. S., Dennis, J. J., Jacobs, R. L.
Abstract: Untreated eggs of the tick Amblyomma hebraeum Koch (Acari: Ixodidae) exhibited antimicrobial activity (AMA) against Gram-negative but not Gram-positive bacteria; eggs denuded of wax by solvent extraction showed no AMA. The unfractionated egg wax extract, however, showed AMA against...

Antimony in recent, ombrotrophic peat from Switzerland and Scotland: Comparison with natural background values (5,320 to 8,020 (14)C yr BP) and implications for the global atmospheric Sb cycle
Download2004
Shotyk, W., Chen, B., Krachler, M.
Abstract: [1] The lowest concentrations, atmospheric fluxes, and enrichments of Sb in a Swiss bog were found in peat samples dating from 8,020 to 5,320 (14)C yr BP when Sb inputs were proportional to those of Sc and effectively controlled by deposition of soil dust. For comparison with these...
