Available in PDF, EPUB and Kindle. Book excerpt: Measuring the exchange of larvae is fundamental to understanding the population dynamics of marine organisms and designing effective management and restoration strategies for them. Population connectivity in the sea has been difficult to measure directly due to the small size and high mortality of marine larvae and their vast potential dispersal area. In three separate studies I examined larval dispersal in three groups of invertebrates on the California coast. The first study estimated the dispersal potential of 501 southern California bight polychaete species using known or inferred life-history characteristics, and related this potential to the species' distributions. Increased potential to disperse was related to higher occurrence frequencies in samples collected from soft-sediment habitats on the Channel Island shelves, but not on southern California mainland shelves. Channel Island polychaetes had lower dispersal potentials than their mainland counterparts, which may make Channel Island marine reserves comparatively more effective at maintaining local reproduction and, as a consequence, biodiversity. The second study explored the use of trace-elemental fingerprinting techniques to measure dispersal directly. These techniques have been previously utilized on larvae that retain calcified structures through development, such as fish or molluscs. We explored the use of trace-elemental fingerprinting on larvae that lack such structures. We found fine-scale chemical variation in porcelain crab embryos at 16 sites along 175 kilometers of coastline. This variation could potentially be used as a site- or region-specific fingerprint to assign settled porcelain crab larvae back to their point of origin. The third study employed trace-elemental fingerprinting to track the larvae of the Olympia oyster among four estuaries in southern California. Settled larvae collected at eight sites in 2007 were assigned to one of three source regions by comparing the chemistry of the portion of their shell formed during brooding with brooded shells collected at the same sites. Significant larval exchange occurred among all three regions separated by as many as 75 kilometers of coastline. The majority of recruits to San Diego Bay and two north San Diego County lagoons were self-recruits, and these two regions produced the majority of recruits to Mission Bay

This book was released on 2007 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dispersal and speciation in the marine environment have long been key topics in evolutionary biology and more recently in conservation biology. The genus Sebastes, with approximately 110 species, is found throughout most of the world's cold-temperate seas. Their breadth of phenotypic and species diversity, ecological dominance, and importance to world fisheries has made them a focus of intensive study by countless researchers. In this dissertation, DNA sequence and microsatellite data were used to investigate patterns of speciation, distribution, and mating habits. In Chapter I, DNA sequence data from seven mitochondrial and two nuclear genes, were used to evaluate possible geographic origin, patterns and timing of dispersal, speciation patterns and drivers, and inter-species relationships. The data support a middle Miocene origin for Sebastes spp. in deep habitats of the Northwest Pacific followed by dispersal into the Northeast Pacific and eventually into the southern hemisphere, driven by progressive cooling and strengthening of major ocean currents. Previous hypothesized relationships, shown to be mostly poly- or para- phyletic, were revised in light of the findings. Chapter I provided evidence for two new "cryptic" species. In Chapter II, sequence of the mitochondrial cytochrome b gene, in combination with nine microsatellite loci, was used to evaluate the geographic and bathymetric range of the vermilion rockfish species complex, as well as test for reproductive isolation between the putative species. Genetic analyses supported the presence of two species, separated primarily by depth of adult occurrence. This finding, in association with distribution patterns of 12 recent species pairs, suggests a novel speciation mode based upon the loss/truncation of an ontogenetic migration phase. In Chapter III, DNA sequence data from Chapter II was used to evaluate patterns of population connectivity and gene flow within the vermilion rockfish. A range-wide analysis showed high levels of genetic heterogeneity, likely driven by limited larval dispersal and barriers to gene flow across major oceanographic features. Patterns of paternity and mating system were investigated in Chapter IV using microsatellite loci. Paternity analyses were performed on larvae from both captive and wild populations, representing most major lineages found in Chapter I. Ten of the 17 examined species, showed evidence for multiple sires within a single brood. The implications for genetic diversity produced by this polygynandrous mating system are discussed.
