Available in PDF, EPUB and Kindle. Book excerpt: In 2015 three leading scientific experts on nudibranchs and sea slugs collaborated to produce a comprehensive guide for divers and scientists to the Indo-Pacific region. After only three years, Nudibranch and Sea Slug Identification Indo-Pacific has sold out and become outdated due to the discovery of new species and numerous changes to the taxonomy of these organisms. On 1 November 2018, a new 2nd Edition will be realeased -- updated and reorganised, including 185 new species. Among other features, the new edition includes additional photographs of species, an identification key, and an up-to-date classification. The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas. This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many organisms have complex life cycles that include ontogenetic niche shifts, or changes to morphology, physiology, diet, predators, and habitat. Natural selection favors individuals that choose the optimal time to undergo ontogenetic niche shifts that avoids unnecessary losses to fitness, and niche shift timing is therefore considered a plastic trait. Hatching is a common niche shift within animals, and modifications to hatch timing can mediate the costs and benefits of hatching sooner or later, depending on varying predation risk, resource availability, or habitat conditions. Predator-induced hatching plasticity in particular is well-documented within amphibians as well as other terrestrial vertebrates and arthropods, but few cases have been documented in the marine environment. This is likely due to the difficulty of making observations of hatching activity, as many marine invertebrates hatch as near-microscopic larvae. The purpose of this study was to develop hatching detectors that improve the ease and frequency of observations of hatching and then demonstrate their utility in investigations of hatching plasticity of two nudibranch species. The hatching detectors, comprised of an array of paired infrared emitters and phototransistors, measure fluctuations in absorbed infrared light to detect hatching. Coupled with wireless transmissions of hatching data, these sensors allowed quasi-real-time monitoring of hatching activity and high-temporal resolution estimates of hatch timing with minimal disturbance to developing embryos. Using these hatching detectors, I wanted to examine whether the nudibranchs H. crassicornis and O. bilamellata exhibit hatch timing plasticity. Given their benthic development within embryo masses and planktonic development after hatching, I hypothesized that both species would accelerate hatch timing when their embryo masses were presented with predation cues from benthic predators. I first investigated hatching plasticity in the aeolid H. crassicornis in response to a simulated predator attack (disruption of the embryo mass outer envelope at age 7 d) and to chemical cues from the embryo predator Heptacarpus brevirostris and the non-predator Petrolisthes eriomerus in a fully-crossed experimental design. There was an apparent interaction between the mechanical cue and embryo mass batch where the simulated predator attack had no effect on the first batch of embryo masses but reduced time-to-hatching in the second batch of embryo masses. The chemical cue had no significant effect on hatch timing. I performed another experiment with the dorid O. bilamellata to determine if they modify hatch timing in response to chemical cues from the embryo predator H. brevirostris or the non-predator Nucella lamellosa, but also found no significant effect. Although this study did not find clear evidence of predator-induced hatching plasticity in these two nudibranchs species, the hatching detectors functioned as intended and provide a means to facilitate future examinations of hatching plasticity in animals with similar life histories.

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.
