This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Members of the sea anemone genus Metridium are widespread through the circumboreal waters of the northern hemisphere. Multiple populations of Metridium senile have been introduced to South America and also South Africa, but these populations and the ability of M. senile to be transported long-distances is not well understood. As marine species commonly exhibit minimal morphological variation, molecular studies have been instrumental in identifying divergence and relationships. My research seeks to describe and understand the processes driving the current distribution of the species within Metridium. Beginning with Chapter 1, I give an in-depth introduction to Metridium. In Chapter 2, I test the temperature and salinity tolerance of M. senile in Japan. I find that the tolerance of M. senile is very broad, particularly for a cold-water sea anemone, but that asexual reproduction only takes place within the comfortable temperature and salinity range. The ability of M. senile to withstand temperature and salinity fluctuations as it applies to being a successful invader is further examined in Chapter 3 through broadly looking at several species of sea anemones. In this chapter, I review and consolidate information on the ten most well-known species of sea anemones that have been introduced outside of their native range, and elucidate specific characteristics that are common among these species. I pair these characteristics with vector potential and suggest how conditions both at the new location and in transit facilitate the introduction of each these species. In Chapters 4 & 5, I move into examining relationships both at the species and population level within Metridium to answer questions directly related to their current distribution. Genetic data has not recently been used to elucidate relationships within Metridium; thus, with the rapid evolution of genomic scale data as applied to biogeographic questions, we can now apply these data to worldwide datasets. In Chapter 4, I test multiple types of genetic data on small test datasets of Metridium to determine which method would be most efficient to use to answer my remaining questions, and I find that sequence capture data provides high resolution at both the species level and at the population level. I apply this knowledge in Chapter 5 to a scaled-up dataset of Metridium (n=236) that encompasses both the native range and several introduced populations in the southern hemisphere to confirm species boundaries, explore the dispersal history, and assess the influence of anthropogenic activities on the current distribution and genetic structure. I identify that there are multiple introductions to the southern hemisphere oceans, and that the introduced populations are spreading to new areas. Within the native range, there is admixture between oceans due to transport of the species, and hybridization between Metridium farcimen and M. senile occurs in human-disturbed habitat.

This book was released on 2020-11-09 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive study of biological molecules acquired from marine organisms, which have been exploited for drug discovery with the aim to treat human diseases. Biomolecules have potential impacts on a diverse range of fields, including medical and pharmaceutical science, industrial science, biotechnology, basic research, molecular science, environmental science and climate change, etc. To understand and effectively apply medicinally important biomolecules, multidisciplinary approaches are called for. The ocean remains a rich biological resource, and the vast untapped potential of novel molecules from marine bio-resources has caught the interest of more and more researchers. These novel biological compounds have never been found in terrestrial or other ecosystems, but only in this rich niche. Advances in sampling techniques and technologies, along with increased funding for research and nature conservation, have now encouraged scientists to look deeper in the waters. Aquaculture supports both tremendous seafood production and the bulk production of marine-derived drugs. Furthermore, molecular methods are now being extensively employed to explore the untapped marine microbial diversity. With the help of molecular and biotech tools, the ability of marine organisms to produce new biosynthetic drugs can be greatly enhanced. This book provides an extensive compilation of the latest information on marine resources and their undisputedly vital role in the treatment of diverse ailments.

Download or read book Habitat Structure written by S.S. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.

Download or read book Invasion Ecology written by Julie L. Lockwood and published by John Wiley & Sons. This book was released on 2013-04-05 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of Invasion Ecology provides a comprehensive and updated introduction to all aspects of biological invasion by non-native species. Highlighting important research findings associated with each stage of invasion, the book provides an overview of the invasion process from transportation patterns and causes of establishment success to ecological impacts, invader management, and post-invasion evolution. The authors have produced new chapters on predicting and preventing invasion, managing and eradicating invasive species, and invasion dynamics in a changing climate. Modern global trade and travel have led to unprecedented movement of non-native species by humans with unforeseen, interesting, and occasionally devastating consequences. Increasing recognition of the problems associated with invasion has led to a rapid growth in research into the dynamics of non-native species and their adverse effects on native biota and human economies. This book provides a synthesis of this fast growing field of research and is an essential text for undergraduate and graduate students in ecology and conservation management.

Download or read book An Introduction to the Invertebrates written by Janet Moore and published by Cambridge University Press. This book was released on 2006-09-21 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: So much has to be crammed into today's biology courses that basic information on animal groups and their evolutionary origins is often left out. This is particularly true for the invertebrates. The second edition of Janet Moore's An Introduction to the Invertebrates fills this gap by providing a short updated guide to the invertebrate phyla, looking at their diverse forms, functions and evolutionary relationships. This book first introduces evolution and modern methods of tracing it, then considers the distinctive body plan of each invertebrate phylum showing what has evolved, how the animals live, and how they develop. Boxes introduce physiological mechanisms and development. The final chapter explains uses of molecular evidence and presents an up-to-date view of evolutionary history, giving a more certain definition of the relationships between invertebrates. This user-friendly and well-illustrated introduction will be invaluable for all those studying invertebrates.
