Available in PDF, EPUB and Kindle. Book excerpt: Population genomics has provided unprecedented opportunities to unravel the mysteries of marine organisms in the oceans' depths. The world's oceans, which make up 70% of our planet, encompass diverse habitats and host numerous unexplored populations and species. Population genomics studies of marine organisms are rapidly emerging and have the potential to transform our understanding of marine populations, species, and ecosystems, providing insights into how these organisms are evolving and how they respond to different stimuli and environments. This knowledge is critical for understanding the fundamental aspects of marine life, how marine organisms will respond to environmental changes, and how we can better protect and preserve marine biodiversity and resources. This book brings together leading experts in the field to address critical aspects of fundamental and applied research in marine species and share their research and insights crucial for understanding marine ecosystem diversity and function. It also discusses the challenges, opportunities and future perspectives of marine population genomics.

This book was released on 2011 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: A central goal of ecology is to understand the forces driving the distribution and abundance of organisms. However, understanding the population dynamics of high-dispersal species, their conservation, and the connections between population dynamics and evolution remains difficult. It is in this context that marine organisms provide a particularly intriguing and challenging study system. Their population dynamics are often highly stochastic, most species have a great ability to disperse, and as the last group of wild species exploited commercially, their ecology and evolution can be strongly influenced by human behavior. By using population genetics, modeling, and meta-analysis, this thesis investigates the spatial ecology of reef fish and the causes and evolutionary consequences of global fisheries collapse. One of the first challenges in understanding spatial population dynamics is obtaining accurate measurements of dispersal abilities. This has been especially difficult for marine species with pelagic larvae. In Chapter 1, I apply a new approach to measuring single-generation dispersal kernels in Clark's anemonefish (Amphiprion clarkii) in the central Philippines. After developing two methods for measuring the strength of local genetic drift, my results suggest that larval dispersal kernels in A. clarkii had a spread near 11 km (4-27 km). This study shows that ecologically relevant larval dispersal can be estimated with widely available genetic methods when effective density is measured carefully through cohort sampling and ecological censuses. In Chapter 2, I use dispersal kernels to develop a model for population openness. Openness refers to the degree to which populations are replenished by immigrants or by local production, a factor that has strong implications for population dynamics, species interactions, and response to exploitation. It is also a population trait that has been increasingly measured empirically, though we have until now lacked theory for predicting population openness. I show that considering habitat isolation elegantly explains the existence of surprisingly closed populations in high dispersal species, and that relatively closed populations are expected when patch spacing is more than twice the standard deviation of a species' dispersal kernel. In addition, empirical scales of habitat patchiness on coral reefs are sufficient to create both largely open and largely closed populations. We predict that habitat patchiness has strong control over population replenishment pathways for a wide range of marine and terrestrial species with a highly dispersive life stage. While the first tow chapters have strong implications for the design of regional marine protected areas, I turn to global conservation questions in Chapters 3 and 4. I first ask which marine fishes are most vulnerable to human impacts. Surveys of terrestrial species have suggested that large-bodied species and top predators are the most at risk, but there has been no global test of this hypothesis in the sea. Contrary to expectations, two datasets compiled from around the world suggest that up to twice as many fisheries for small, low trophic level species have collapsed as compared to those for large predators. I then show that collapsed and overfished species have lower genetic diversity than their close relatives. While the ecological and ecosystem impacts of harvesting wild populations have long been recognized, it has been controversial how widespread evolutionary impacts are. Using a meta-analytical approach across 37 taxonomically paired comparisons, I find on average 19% fewer alleles per locus in overfished species, but little difference in heterozygosity. I confirm with simulations that these results are consistent with a recent population bottleneck. These results suggest that the genetic impacts of overharvest are widespread, even among abundant species. A loss of allelic richness has implications for the long-term evolutionary potential of species.

Available in PDF, EPUB and Kindle. Book excerpt: SUSTAINABLE FISHERY SYSTEMS An up-to-date and interdisciplinary guide to sustainable fisheries Fisheries, whether small-scale or large-scale, are filled with complexity and uncertainty. Making the right decisions to successfully manage fisheries for sustainability and resilience requires a systems approach — including both natural and human elements, and their many interactions. To understand fisheries, and how they change over time, a diverse range of fishery knowledge must be brought together. Sustainable Fishery Systems, 2nd edition meets these needs. The new edition provides essential information that can be readily applied within government, community, industrial, academic and research settings. Sustainable Fishery Systems, 2nd edition retains the first edition’s emphasis on themes such as sustainability, resilience, uncertainty, complexity, and conflict, and expands its treatment of topics that have, since the first edition’s publication, become crucial to consider in the field of fisheries. As a result, readers will find: Updated and expanded coverage of topics including coastal conservation, ecosystem-based management, co-management, community-based management, and more New chapters covering connections between fisheries and marine protected areas, biodiversity conservation, climate and fisheries, and multi-sectoral management A more detailed introduction to the “systems” perspective of fisheries, reflecting the substantial growth in that subject’s importance, and covering in detail the natural, human and governance aspects of fisheries. Sustainable Fishery Systems, 2nd edition is an indispensable interdisciplinary resource for educators, researchers, government agencies, and fisheries managers.

This book was released on 2019-01-07 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Law Library presents the complete text of the Endangered and Threatened Species - Puget Sound - Georgia Basin Distinct Population Segments of Yelloweye Rockfish, Canary Rockfish and Bocaccio (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), issue a final rule to designate critical habitat for three species of rockfish listed under the Endangered Species Act (ESA): the threatened yelloweye rockfish (Sebastes ruberrimus) Distinct Population Segment (DPS), the threatened canary rockfish (S. pinniger) DPS, and the endangered bocaccio (S. paucispinus) DPS (listed rockfish) pursuant to section 4 of the ESA. The specific areas in the final designation include 590.4 square miles (1529 square km) of nearshore habitat for canary rockfish and bocaccio, and 414.1 square miles (1072.5 square km) of deepwater habitat for yelloweye rockfish, canary rockfish and bocaccio. This final designation represents a reduction of approximately 15.2 percent (180.3 sq mi, 467 sq km) for canary rockfish and bocaccio, and a reduction of approximately 28 percent (160 sq mi, 416.2 sq km) for yelloweye rockfish, compared to our proposed critical habitat rule on August 6, 2013 (78 FR 47635). We exclude some particular areas from designation because the benefits of exclusion outweigh the benefits of inclusion and exclusion of those areas will not result in the extinction of the species. No areas were excluded based on economic impacts. This ebook contains: - The complete text of the Endangered and Threatened Species - Puget Sound - Georgia Basin Distinct Population Segments of Yelloweye Rockfish, Canary Rockfish and Bocaccio (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
