Because of the importance of the soft-bottom fish fauna to fisheries and to environmental assessments, the biology and ecology of the fauna have been relatively well studied. However, although the fauna has been relatively well studied off California and Pacific Baja California, there is no overall summary of the soft-bottom fish fauna and its ecology for the entire region. This chapter summarizes what is known about the ecology of the soft-bottom fish fauna of the continental shelf and upper slope of the California and the Pacific coast of the Baja California Peninsula. It begins with an overview of the physical conditions of the habitat, followed by overviews of scientific study, sampling methods, the soft-bottom fish fauna of the Californias (e.g., taxonomic composition, biogeography, morphology, life-history traits, assemblages, and community organization). It also compares this fauna to similar faunas elsewhere in the world, and ends with prospects for future research.Less

This chapter presents an overview of the within-plant variability of continuous structural and morphological traits of reiterated plant structures. It is found that all types of reiterated structures may exhibit considerable levels of continuous within-plant variation, and that, for any given structure, variability varies greatly among species. Comparisons between different structures should ideally be performed on data obtained from the same species and individuals by means of some paired comparison method, in order to avoid possible artifacts due to some combination of phylogenetic correlations and differences in the taxonomic composition of species samples. The results of the comparison between structures differ depending on the metric used to measure variability. Information from cultivated plants reveals that within-plant variation in the chemical composition of seeds can also be extensive.Less
