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 2019 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Ficopomatus enigmaticus is a marine annelid invasive to many locations around the world. It was first identified as a non-indigenous species in San Francisco Bay, California in the 1920s, and since then it has been found in other parts of California. Because the full extent of the distribution of F. enigmaticus was unknown, I conducted surveys for the presence or absence of this species along the coast of California. Populations of F. enigmaticus were found at 23 of the 136 sites surveyed along the coast of California. Ficopomatus enigmaticus was found to be widespread in San Francisco Bay, Monterey Bay, and southern California.

This book was released on 2018 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: "More than seventy percent of the earth's surface is covered by the ocean which is home to a staggering and sometimes overwhelming diversity of organisms, the majority of which reside in pelagic form. Marine invertebrate larvae are an integral component of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This accessible, upper-level text provides an important and timely update on the topic of larval evolution and ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content is structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; larval ecology in extreme and changing environments. This novel synthesis integrates traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research to provide a research and teaching tool for decades to come." -- from the rear cover.

This book was released on 2011 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overarching theme of my thesis is to explore patterns of larval dispersal as they relate to management of fished marine species. I employed a case study of two species: Megastraea undosa and Parastichopus parvimensis to investigate patterns of phylogeography and assess relative scales of dispersal for these two species which are fished in both California, USA and Baja California, MEX. To examine how some generalities for many species can be made for a specific geographic area, I reviewed all existing phylogeographic studies around Cape Mendocino, CA. Dispersal at a snail's pace: Strong genetic structure in the fisheries gastropod Megastaea undosa. Information about larval dispersal is necessary for effective management of fisheries. Population genetics are often employed to assess dispersal, but these data also carry artifacts from the evolutionary history of a species. I assessed historical and modern demography of the wavy top snail, Megastraea undosa, a marine snail that is fished in California, USA and Baja California, Mexico. Genetic structure at the COI mtDNA locus is strikingly high, with large shifts in haplotype frequencies between southern Baja and southern California. Coalescent-based modeling of genetic data suggests that the population has limited dispersal throughout the range and underwent a northward range expansion after the last glacial maximum. I conclude that both historical and contemporary processes affect observed patterns of phylogeography in M. undosa. Consideration of the evolutionary history of target species allows for a more accurate interpretation of genetic data for management. iv Subtle genetic structure in the commercially fished warty sea cucumber, Parastichopus parvimensis. The warty sea cucumber, P. parvimensis, is fished commercially in both California, USA and Baja California, Mexico but little is known about the status of the fisheries or if separate stocks exist. P. parvimensis has a long pelagic larval duration of 50-90 days, which may translate to high connectivity throughout the species range (Monterey, CA, USA to Bahía Asuncion, BCS, Mexico). I examined phylogeographic patterns at the COI mtDNA locus and five microsatellite loci throughout the range of P. parvimensis and was particularly interested in patterns associated with the potential phylogeographic barriers of Point Conception, CA, USA and Punta Eugenia, BCS, MEX. I found no structure associated with Point Conception, but subtle genetic structure at both types of loci for Punta Eugenia, which may be mechanistically explained by oceanographic patterns. These data have important implications for management of the sea cucumber fishery and indicate that populations south of Punta Eugenia likely do not receive biologically meaningful input of larvae from northern populations to supplement the local fishery. Concordant phylogeographic patterns associated with the major headland of Cape Mendocino in northern California. Most coastlines are non-linear and headlands such as Cape Mendocino may interact with oceanographic processes to create barriers to dispersal. Though Cape Mendocino is a prominent headland, it has been largely ignored in the phylogeographic literature, which focuses instead on Point Conception in southern California. I reviewed and synthesized phylogeographic studies that include sampling sites north and south of Cape Mendocino and discuss the v oceanography and topography of the cape as potential mechanistic drivers of larval dispersal patterns. Slightly more than half (24 out of 46) of the surveyed species that showed significant genetic structure around this headland, which suggests that this headland may be an important barrier to dispersal and may limit connectivity between northern and central California. If populations north of Cape Mendocino have higher connectivity with populations in Oregon than with those in central California, marine spatial planning must occur at a multi-state scale to reach marine conservation goals.

Available in PDF, EPUB and Kindle. Book excerpt: Pioneered in the late 1980s, the concept of macroecology—a framework for studying ecological communities with a focus on patterns and processes—revolutionized the field. Although this approach has been applied mainly to terrestrial ecosystems, there is increasing interest in quantifying macroecological patterns in the sea and understanding the processes that generate them. Taking stock of the current work in the field and advocating a research agenda for the decades ahead, Marine Macroecology draws together insights and approaches from a diverse group of scientists to show how marine ecology can benefit from the adoption of macroecological approaches. Divided into three parts, Marine Macroecology first provides an overview of marine diversity patterns and offers case studies of specific habitats and taxonomic groups. In the second part, contributors focus on process-based explanations for marine ecological patterns. The third part presents new approaches to understanding processes driving the macroecolgical patterns in the sea. Uniting unique insights from different perspectives with the common goal of identifying and understanding large-scale biodiversity patterns, Marine Macroecology will inspire the next wave of marine ecologists to approach their research from a macroecological perspective.

This book was released on 2017-10-01 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.

Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.
