Global patterns in species richness have resisted explanation since they first caught the attention of ecologists in the 1960s. The failure of ecology to fully integrate the diversity issue into its core of accepted wisdom derives from an inappropriate concept of community and the rejection of history and region as formative contexts for ecological systems. Traditionally, ecologists have held t...

Contemporary societies, governments, individuals are all facing problems linked directly or indirectly to the functioning of ecological systems. Whatever the reason underlying these problems – be it the necessary use of biological resources, the elimination or recycling of wastes, our inevitable dependence on ecosystem services – neither politics nor ecology can afford to ignore them, and polit...

Chemical, biological, and physical processes lead to distinctive "isotopic signatures" in biological materials that allow tracing of the origins of organic substances. Isotopic variation has been extensively used by plant physiological ecologists and by paleontologists, and recently ecologists have adopted the use of stable isotopes to measure ecosystem patterns and processes. To date, animal p...
