Download or read book Shark Research written by Jeffrey C Carrier and published by CRC Press. This book was released on 2018-09-03 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

Download or read book Biology of Sharks and Their Relatives written by Jeffrey C. Carrier and published by CRC Press. This book was released on 2022-06-08 with total page 841 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology of Sharks and Their Relatives is an award-winning and groundbreaking exploration of the fundamental elements of the taxonomy, systematics, physiology, and ecology of sharks, skates, rays, and chimera. This edition presents current research as well as traditional models, to provide future researchers with solid historical foundations in shark research as well as presenting current trends from which to develop new frontiers in their own work. Traditional areas of study such as age and growth, reproduction, taxonomy and systematics, sensory biology, and ecology are updated with contemporary research that incorporates emerging techniques including molecular genetics, exploratory techniques in artificial insemination, and the rapidly expanding fields of satellite tracking, remote sensing, accelerometry, and imaging. With two new editors and 90 contributors from the US, UK, South Africa, Portugal, France, Canada, New Zealand, Australia, India, Palau, United Arab Emirates, Micronesia, Sweden, Argentina, Indonesia, Cameroon, and the Netherlands, this third edition is the most global and comprehensive yet. It adds six new chapters representing extensive studies of health, stress, disease and pathology, and social structure, and continues to explore elasmobranch ecological roles and interactions with their habitats. The book concludes with a comprehensive review of conservation policies, management, and strategies, as well as consideration of the potential effects of impending climate change. Presenting cohesive and integrated coverage of key topics and discussing technological advances used in modern shark research, this revised edition offers a well-rounded picture for students and researchers.

Download or read book Stock Identification Methods written by Steven X. Cadrin and published by Academic Press. This book was released on 2013-10-04 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis Focuses on the challenges of interpreting data and managing mixed-stock fisheries

This book was released on 2020 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Understanding the minimum energetic expenditure for a species across its life stages has practical value in predicting how species may respond to changing habitat conditions. Using a static respirometry, I measured the thermal sensitivity (Q10) and metabolic allometry of the round stingray, Urobatis halleri, based on their standard metabolic rate (SMR). A total of 33 individuals (mass range=0.03 – 0.86 kg) were acclimated for > 14 days at three temperature treatments (15°, 23°, 27°C) spanning the seasonal water temperature variation in Southern California. An average thermal sensitivity (Q10) of 3.2 was estimated for the round stingray across the range of experimental temperatures. The juvenile size class showed a higher Q10 coefficient (Q10=4.3) when compared to the adults (Q10=3.0). There was a negative relationship between this species mass-specific scaling exponent (b) and temperature treatment (b=0.99 at 15°C, b=0.86 at 23°C, and b=0.79 at 27°C). Metabolic Q10 estimations showed that the round stingray is relatively sensitive to the thermal fluctuations they experience in southern California. While a relatively high Q10 may allow this species the ability to optimize their daily net energy gain by exploiting the local thermal heterogeneity, a higher thermal sensitivity in juveniles could have adverse effects on the population fitness under a pervasive increase of ocean’s temperature. Because of the scaling exponent can be affected by temperature, modeling studies should consider correcting for this effect when using scaling relationships as an input for more precise bioenergetic models.
