Bio-hydrogen: microbes have their own agenda.
The international hydrogenase community stages a meeting every 3-4 years, and this time it was held in the University of Reading. Each congress has revealed new aspects of the complex nature of hydrogenases: their structure, molecular mechanisms and biosynthesis are all yielding up their secrets. This following introduction provides background information, and the highlights of the meeting are ...
متن کاملTrophic ecology of invasive Argentine ants in their native and introduced ranges.
Although the ecological effects of invasions often become obvious soon after introduced species become established, more gradual effects may take years to manifest and can thus require long-term data for quantification. We analyzed an 8-year record of stable isotope data on Argentine ants (Linepithema humile) from southern California to infer how the trophic position of this widespread invasive...
متن کاملTrap-mulching Argentine ants.
Argentine ant, Linepithema humile (Mayr), management is constrained, in large part, by polydomy where nestmates are distributed extensively across urban landscapes, particularly within mulch. Management with trap-mulching is a novel approach derived from trap-cropping where ants are repelled from a broad domain of nest sites to smaller defined areas, which are subsequently treated with insectic...
متن کاملDetrimental effects of highly efficient interference competition: invasive Argentine ants outcompete native ants at toxic baits.
The Argentine ant (Linepithema humile) is an invasive species that disrupts the balance of natural ecosystems by displacing indigenous ant species throughout its introduced range. Previous studies that examined the mechanisms by which Argentine ants attain ecological dominance showed that superior interference and exploitation competition are key to the successful displacement of native ant spe...
متن کاملAn experimental study of competition between fire ants and Argentine ants in their native range.
An understanding of why introduced species achieve ecological success in novel environments often requires information about the factors that limit the abundance of these taxa in their native ranges. Although numerous recent studies have evaluated the importance of natural enemies in this context, relatively few have examined how ecological success may result from differences in the magnitude o...
