Mass mortalities of species can fundamentally alter the structure of natural communities, which can in turn negatively impact species’ recovery. Beginning in 1994, some of the largest remaining populations of black abaloneHaliotis cracherodii on the mainland coast of California, experienced mass mortalities due to the fatal disease called ‘withering syndrome’, which led to its listing as a species of concern by the USA National Marine Fisheries Service. We have been monitoring black abalone populations along the coast of southern and central California since 1992, and detection of withering syndrome at our southernmost site prompted us to investigate how the …

The application of mass spectrometry (MS) to the study of progressively larger and more complex macromolecular assemblies is proving increasingly useful for structural biologists. The scope of this approach has recently been widened through the application of a tandem MS procedure. This two-step technique involves the selection of specific assemblies in the gas phase, and inducing their dissociation through collisions with argon atoms. Here we investigate the mechanism of this process and show that dissociation of subunits from a macromolecular assembly follows a sequential pathway, with the partitioning of charge between the dissociation products governed primarily by their relative surface …
