The distribution of organisms in relation to the physical environment has long fascinated biologists and ecologists. In marine ecosystems, organismal distributions are often described by gradients in the physical environment, such as along an exposure gradient on the wave-swept rocky shore or a light gradient from surface waters to the deepest depths. I will discuss the roles of physical stress (along temperature and salinity gradients), physiological response, and recruitment success in the distribution of an invasive and a native mussel (Genus Mytilus) in California. In addition to providing the first comparative physiological study on the differences between native and invasive species, this work has deepened my interest in the dispersal abilities of larval invertebrates in coastal and deep oceans. This talk will end with a brief description of my plans for developing a species identification microarray of larval invertebrates—the focus of my postdoctoral project here at MBARI—in conjunction with the Vrijenhoek and Scholin labs.
