Available in PDF, EPUB and Kindle. Book excerpt: The accelerating rise in global trade and travel means that our world is more interconnected than ever before. This trend could severely impact species and ecosystems globally, as it increases opportunities for species to invade regions beyond their natural range. In this thesis, I combine ecological theory and data synthesis with empirical field-studies to tackle the questions of what makes some communities more easily invaded than others, and how can both natural and anthropogenic control interventions affect the persistence and impacts of invasive species. I first evaluate the relationship between native species diversity and invasibility, or the vulnerability of a community to invasion. Using a meta-analytic approach, I show that the conflicting patterns between diversity and invasibility that are often observed in the literature are likely due to not only differences in spatial scales between studies but also to differences in the metrics researchers use to measure invader success. I then use the invasion of Caribbean coral reefs by the predatory Indo-Pacific lionfish as a model system to test natural and anthropogenic means of controlling the invader. Using a combination of fisheries-derived sampling of native grouper predators and a field experiment conducted across a gradient of grouper abundance, I examine the ability of native grouper predators to mitigate the negative effects of lionfish predation in the Bahamas. I reveal little evidence for direct predation by groupers on lionfish, but show that fear of native groupers alone by lionfish is sufficient to evoke behavioural changes in lionfish that could potentially reduce their impact on native prey. Finally, I use a long-term field experiment to investigate the ecological effectiveness of infrequent culling (i.e., the physical removal of lionfish from reefs by divers). I demonstrate that infrequent culling can reduce lionfish abundance, but is insufficient to halt the decline in native prey fish biomass. Moreover, I show that large-scale natural disturbances, like hurricanes, and density-dependent movement by lionfish from neighbouring reefs can undermine culling efforts. Overall, my thesis reveals that the development of standardized metrics is key to generate a holistic understanding of invasion dynamics, and that both natural and anthropogenic control over invaders is unlikely to stymy biological invasions at the scale currently observed for Indo-Pacific lionfish in the Caribbean.
Book Synopsis Biology, Ecology, Control and Management of the Invasive Indo-Pacific Lionfish by : James Adiel Morris (Jr.)
Download or read book Biology, Ecology, Control and Management of the Invasive Indo-Pacific Lionfish written by James Adiel Morris (Jr.) and published by . This book was released on 2009 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Venomous Indo-Pacific lionfish (Pterois miles and P. volitans) are now established along the Southeast U.S.A. and parts of the Caribbean and pose a serious threat to reef fish communities of these regions. Lionfish are likely to invade the Gulf of Mexico and potentially South America in the near future. Introductions of lionfish were noted since the 1980s along south Florida and by 2000 lionfish were established off the coast of North Carolina. Lionfish are now one of the more numerous predatory reef fishes at some locations off the Southeast U.S.A. and Caribbean. Lionfish are largely piscivores that feed occasionally on economically important reef fishes. The trophic impacts of lionfish could alter the structure of native reef fish communities and potentially hamper stock rebuilding efforts of the Snapper -Grouper Complex. Additional effects of the lionfish invasion are far-reaching and could increase coral reef ecosystem stress, threaten human health, and ultimately impact the marine aquarium industry. Control strategies for lionfish are needed to mitigate impacts, especially in protected areas. This integrated assessment provides a general overview of the biology and ecology of lionfish including genetics, taxonomy, reproductive biology, early life history and dispersal, venom defense and predation, and feeding ecology. In addition, alternative management actions for mitigating the negative impacts of lionfish, approaches for reducing the risk of future invasions, and directions for future research are provided"--Summary.
Book Synopsis Biological Invasions and Animal Behaviour by : Judith S. Weis
Download or read book Biological Invasions and Animal Behaviour written by Judith S. Weis and published by Cambridge University Press. This book was released on 2016-10-13 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does behaviour affect biological invasions? Can it explain why some animals are such successful invaders? With contributions from experts in the field, and covering a broad range of animals, this book examines the role of behaviour in biological invasions from the point of view of both invaders and native species. The chapters cover theoretical aspects, particularly relevant behaviours and well-documented case studies, showing that behaviour is critical to the success, and ecological and socio-economic impact, of invasive species. Its insights suggest methods to prevent and mitigate those impacts, and offer unique opportunities to understand the adaptive role of behaviour. Offering a comprehensive overview of current understanding on the subject, the book is intended for biological invasion researchers and behavioural ecologists, as well as ecologists and evolutionary biologists interested in how organisms deal with anthropogenic environmental changes such as climate change and habitat loss.
Book Synopsis Ecosystem-Based Fisheries Management by : Jason S. Link
Download or read book Ecosystem-Based Fisheries Management written by Jason S. Link and published by Oxford University Press. This book was released on 2021-11-15 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem-based fishery management (EBFM) is rapidly becoming the default approach in global fisheries management. The clarity of what EBFM means is sharpening each year and there is now a real need to evaluate progress and assess the effectiveness and impacts. By examining a suite of over 90 indicators (including socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria) for 9 major US fishery ecosystem jurisdictions, the authors systematically track the progress the country has made towards advancing EBFM and making it an operational reality. The assessment covers a wide range of data in both time (multiple decades) and space (from the tropics to the poles, representing over 10% of the world's ocean surface area). The authors view progress towards the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight the findings from a national perspective. Although US-centric, the lessons learned are directly applicable for all parts of the global ocean. Much work remains, but significant progress has already been made to better address many of the challenges facing the sustainable management of our living marine resources. This is an essential and accessible reference for all fisheries professionals who are currently practicing, or progressing towards, ecosystem-based fisheries management. It will also be of relevance and use to researchers, teachers, managers, and graduate students in marine ecology, fisheries biology, biological oceanography, global change biology, conservation biology, and marine resource management.

Book Synopsis Introductory Fisheries Analyses with R by : Derek H. Ogle
Download or read book Introductory Fisheries Analyses with R written by Derek H. Ogle and published by CRC Press. This book was released on 2016-01-05 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: A How-To Guide for Conducting Common Fisheries-Related Analyses in R Introductory Fisheries Analyses with R provides detailed instructions on performing basic fisheries stock assessment analyses in the R environment. Accessible to practicing fisheries scientists as well as advanced undergraduate and graduate students, the book demonstrates the flexibility and power of R, offers insight into the reproducibility of script-based analyses, and shows how the use of R leads to more efficient and productive work in fisheries science. The first three chapters present a minimal introduction to the R environment that builds a foundation for the fisheries-specific analyses in the remainder of the book. These chapters help you become familiar with R for basic fisheries analyses and graphics. Subsequent chapters focus on methods to analyze age comparisons, age-length keys, size structure, weight-length relationships, condition, abundance (from capture-recapture and depletion data), mortality rates, individual growth, and the stock-recruit relationship. The fundamental statistical methods of linear regression, analysis of variance (ANOVA), and nonlinear regression are demonstrated within the contexts of these common fisheries analyses. For each analysis, the author completely explains the R functions and provides sufficient background information so that you can confidently implement each method. Web Resource The author’s website at http://derekogle.com/IFAR/ includes the data files and R code for each chapter, enabling you to reproduce the results in the book as well as create your own scripts. The site also offers supplemental code for more advanced analyses and practice exercises for every chapter.
Book Synopsis Predation on Invasive Lionfish Varies with Their Size, Among Habitats, and with Conditioning of Native Predators by : Jessica L. Diller
Download or read book Predation on Invasive Lionfish Varies with Their Size, Among Habitats, and with Conditioning of Native Predators written by Jessica L. Diller and published by . This book was released on 2014 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species often exacerbate global and local stresses on ecosystems, with invaders commonly experiencing a release from enemies, including diseases and predators. Release from predation helps explain the lionfish (Pterois volitans/miles) invasion of the western Atlantic, Caribbean and Gulf of Mexico. However, the extent of biological control exerted by native predators is a topic of debate centered on interpretation of spatial distributions of lionfish and predators. In many places, control of lionfish relies on people acting as predators via culls. In some cases, the resulting dead or injured lionfish are eaten by sharks and groupers, which may condition these naïve, native predators. This study complements existing field surveys by assessing the potential for predation on invasive lionfish at Little Cayman Island, BWI with tethering experiments. We tethered 132 live lionfish (52-220 mm total length) in three different habitats: seagrass beds, rarely culled reefs, and intensely culled reefs. Binary logistic regression indicated that the potential for predation increased slightly (1.02\U+f0b4\), but significantly with 1 mm increases in total length. In addition, lionfish tethered on intensely culled reefs were 30\U+f0b4\ and 14\U+f0b4\ more likely to be taken by piscivores than fish tethered in seagrass or on rarely culled reefs. Overall, results suggested that native predators were capable of consuming healthy, tethered lionfish off Little Cayman Island and the naïveté of native predators was overcome by conditioning. Of course, conditioning designed to increase predation on lionfish, augment culling and help control the invasion must be implemented without endangering people.

Book Synopsis Mesophotic Coral Ecosystems by : Yossi Loya
Download or read book Mesophotic Coral Ecosystems written by Yossi Loya and published by Springer. This book was released on 2019-06-21 with total page 1003 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.
Book Synopsis Marine Conservation by : G. Carleton Ray
Download or read book Marine Conservation written by G. Carleton Ray and published by John Wiley & Sons. This book was released on 2013-12-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a guide for marine conservation practice, Marine Conservation takes a whole-systems approach, covering major advances in marine ecosystem understanding. Its premise is that conservation must be informed by the natural histories of organisms together with the hierarchy of scale-related linkages and ecosystem processes. The authors introduce a broad range of overlapping issues and the conservation mechanisms that have been devised to achieve marine conservation goals. The book provides students and conservation practitioners with a framework for thoughtful, critical thinking in order to incite innovation in the 21st century. "Marine Conservation presents a scholarly but eminently readable case for the necessity of a systems approach to conserving the oceans, combining superb introductions to the science, law and policy frameworks with carefully chosen case studies. This superb volume is a must for anyone interested in marine conservation, from students and practitioners to lay readers and policy-makers." —Simon Levin, George M.

This book was released on 2019-04-05 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean acidification (OA). For the hundreds of millions of people who depend on reefs for food or livelihoods, the thousands of communities that depend on reefs for wave protection, the people whose cultural practices are tied to reef resources, and the many economies that depend on reefs for fisheries or tourism, the health and maintenance of this major global ecosystem is crucial. A growing body of research on coral physiology, ecology, molecular biology, and responses to stress has revealed potential tools to increase coral resilience. Some of this knowledge is poised to provide practical interventions in the short-term, whereas other discoveries are poised to facilitate research that may later open the doors to additional interventions. A Research Review of Interventions to Increase the Persistence and Resilience of Coral Reefs reviews the state of science on genetic, ecological, and environmental interventions meant to enhance the persistence and resilience of coral reefs. The complex nature of corals and their associated microbiome lends itself to a wide range of possible approaches. This first report provides a summary of currently available information on the range of interventions present in the scientific literature and provides a basis for the forthcoming final report.
