BACKGROUND The evolution and spread of antibiotic resistance, as well as the evolution of new strains of disease causing agents, is of great concern to the global health community. Our ability to effectively treat disease is dependent on the development of new pharmaceuticals, and one potential source of novel drugs is traditional medicine. This study explores the antibacterial properties of pl...

BACKGROUND AND AIMS Studies of floral scent evolution often attribute variation in floral scent to differences in pollinator behaviour, ignoring the potential for shared biochemistry between floral scent and floral colour to dictate patterns of phenotypic variation in scent production. To determine the relative effects of shared biochemistry and/or localized population-level phenomena on floral...

hook-tools (Hunt 1996). In many cases only a single instance of the putative intelligent behavior has been observed (e.g. Montevecchi 1978, Andersson 1989). One behavior, the use of automobiles to crack open nuts, has been cited repeatedly as an example of corvid resourcefulness and adaptability (e.g. Beck 1980:127, Hunt 1996). There are only two original reports of this behavior in the literat...

Invasive plants can negatively affect belowground processes and alter soil microbial communities. For native plants that depend on soil resources from root fungal symbionts (RFS), invasion could compromise their resource status and subsequent ability to manufacture and store carbohydrates. Herbaceous perennials that depend on RFS-derived resources dominate eastern North American forest understo...
