Book excerpt: The overarching goal of my thesis is to better understand how sperm whale (Physeter macrocephalus) dialects vary over space and time, and to quantify the implications of these dynamics on cultural identity and evolution in sperm whale vocalizations. Female and immature sperm whales live in matrilineal social units that are stable over time, and different social units only associate if they belong to the same cultural clan. Clans forage, move, dive, associate, and distribute differently, but the primary way we distinguish them is through their unique dialects. These dialects are comprised of stereotyped patterns of clicks, called codas, and my thesis seeks to clarify the interplay between these social vocalizations and cultural identity in sperm whale clans. Inspired by rhythm in codas, I first survey the literature for evidence of rhythm in cetacean vocalizations and use a comparative lens to theorize about the functional roles it plays. I show that rhythm is common in cetacean vocalizations, but that it may be used in different behavioral contexts by mysticetes and odontocetes. In sperm whales, vocal rhythm is apparent across contexts, suggesting that it is a fundamental feature of communication. Next, I introduce a new method (IDcall) that detects putative biological structure in acoustic datasets using characteristic, repeated call types. I show that IDcall's underlying theory is broadly applicable and can be used to detect sperm whale clans from codas, wren subspecies from songs, and cricket species from songs. Using acoustic data from 25 locations spanning 42 years, I then investigate the spatial and temporal dynamics of sperm whale clan dialects. In the spatial domain, I document the presence and distribution of seven clans in the Pacific Ocean, and provide empirical evidence that certain coda types function as symbolic markers of sperm whale clan identity, like ethnic markers in humans. In the temporal domain, I leverage long-term research efforts in the Mediterranean, eastern Caribbean, and Galápagos Islands to show that the fine-scale structure of coda types can change over decadal timespans within clans. Collectively, these findings illustrate the interplay between vocalizations and sociality in sperm whales, and emphasize the need for a global, multi-cultural approach to study and conserve this global, multi-cultural species.
Book Synopsis Ethology and Behavioral Ecology of Odontocetes by : Bernd Würsig
Download or read book Ethology and Behavioral Ecology of Odontocetes written by Bernd Würsig and published by Springer. This book was released on 2019-08-02 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

Book Synopsis Studies of Depredating Sperm Whales (Physeter Macrocephalus) Off Sitka, AK, Using Videocameras, Tags, and Long-range Passive Acoustic Tracking by : Delphine Mathias
Download or read book Studies of Depredating Sperm Whales (Physeter Macrocephalus) Off Sitka, AK, Using Videocameras, Tags, and Long-range Passive Acoustic Tracking written by Delphine Mathias and published by . This book was released on 2012 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation uses videocameras, tags and acoustic recorders to investigate the diving and acoustic behavior of sperm whales in the Gulf of Alaska during natural and depredation foraging conditions. First, underwater videocamera footage of a sperm whale attacking a fisherman's longline at 100 m depth was used to examine its acoustic behavior at close range and to estimate its size both acoustically and visually. Second, bioacoustic tagging data demonstrated that the same individuals displayed different acoustic behaviors during natural and depredation foraging states. Two broad categories of depredation, "shallow" and "deep," were also identified. These results suggest that passive acoustic monitoring at close ranges may yield useful metrics for quantifying depredation activity. Third, the behavioral reactions of depredating sperm whales to a variety of acoustic play¬backs generated at relatively low source levels were investigated using bioacoustic tags. Finally, bioacoustic and satellite tag data were used to develop passive acoustic techniques for tracking sperm whales with a short-aperture two-element vertical array. When numeric sound propagation models were exploited, localization ranges up to 35 km were obtained. The tracking methods were also used to estimate the source levels of sperm whale "clicks" and "creaks", predict the maximum detection range of the signals as a function of sea state, and measure the drift of several whales away from a visual decoy.
Book Synopsis Diet and Movement of Depredating Male Sperm Whales (Physeter Macrocephalus) in the Gulf of Alaska by : Lauren A. Wild

This book was released on 2020 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm whales (Physeter macrocephalus) remove fish from commercial fishing gear in high latitude foraging grounds. This behavior, known as depredation, occurs in the Gulf of Alaska (GOA) sablefish longline fishery and has increased in frequency and severity since the mid-1990s. Sperm whale foraging ecology and movements in the GOA are poorly understood but are important considerations to how depredation impacts fishery resources and whale behavior. The goals of this dissertation were to use stable isotope analysis to evaluate trophic connections between sperm whales and their prey, estimate the proportional contribution of various prey items to sperm whale diets, and use satellite tag data to evaluate movement and diving behavior of sperm whales in the GOA. Understanding isotopic variability in cetacean skin is important to evaluating dietary information from this tissue; thus, in chapter 1, I first analyzed the stable isotope ratios among layers of cetacean skin to determine how much variability there was within and across layers of cetacean skin. Results showed horizontal layers of cetacean skin to be significantly different isotopically, suggesting evidence of a dietary time series in layers of cetacean skin, where the innermost skin layer represents the most recent diet. These results were used in my second chapter to isolate the most recent diet of sperm whales from the inner layer of skin, and then to estimate proportional contributions of different prey to sperm whale diets. Results showed that the sperm whales sampled prefer sablefish, dogfish, skates, and rockfish, and that the proportional contribution of sablefish to sperm whale diets has increased over the past 15 years as depredation has increased in severity. Chapter three presented an analysis of twenty-nine satellite tags placed on depredating sperm whales in the GOA between 2007 and 2016 to explore movement and diving behavior and how these behaviors may be linked to prey preferences found in chapter 2. Tagged sperm whales in the GOA preferred the continental slope habitat and made long migrations along the slope toward Mexico and the Gulf of California, speeding up and switching behaviors from foraging to transiting when they left the GOA. Dive depths and durations exhibited individual variability and were significantly correlated to light levels, lunar cycles, sablefish fishery catch-per-unit-effort, and seafloor depth. Results suggest diving behavior tracks that of primary groundfish prey items, and dive depths become shallower in areas of high sablefish densities, as inferred from fishery catches, potentially reflecting depredation behavior. Together these results provide a much-improved understanding of the impact of depredation on sperm whale dietary preference, and show insights into the importance of the GOA as a foraging ground for endangered sperm whales.

Book Synopsis Marine Mammal Welfare by : Andy Butterworth
Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

Book Synopsis Ecotourism’s Promise and Peril by : Daniel T. Blumstein
Download or read book Ecotourism’s Promise and Peril written by Daniel T. Blumstein and published by Springer. This book was released on 2017-08-22 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intended as a guide for wildlife managers and ecotourism operators, as well as interested ecotourists, this book addresses the biological principles governing how ecotourism affects wildlife. The introductory chapters focus on four key responses to human visitation—behavioral, physiological, ecological, and evolutionary. Readers will discover ecotourism’s effects on biodiversity in connection with various industries that are habitat or taxonomically specific: fish tourism (including both freshwater and marine), marine mammal tourism, the huge industry centered on terrestrial animals, and the well-studied industry of penguin tourism. Given that the costs and benefits of ecotourism cannot be meaningfully assessed without understanding the human context, particular attention is given to how ecotourism has been used as part of community development. In closing, the book synthesizes the current state of knowledge regarding best practices for reducing human impacts on wildlife. The final chapter highlights key research questions that must be addressed to provide more evidence-based guidelines and policy.

Download or read book Pheromones and Animal Behaviour written by Tristram D. Wyatt and published by Cambridge University Press. This book was released on 2003-02-27 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are entering one of the most exciting periods in the study of chemical communication since the first pheromones were identified some 40 years ago. This rapid progress is reflected in this book, the first to cover the whole animal kingdom at this level for 25 years. The importance of chemical communication is illustrated with examples from a diverse range of animals including humans, marine copepods, Drosophila, Caenorhabditis elegans, moths, snakes, goldfish, elephants and mice. It is designed to be advanced, but at the same time accessible to readers whatever their scientific background. For students of ecology, evolution and behaviour, this book gives an introduction to the rapid progress in our understanding of olfaction at the molecular and neurological level. In addition, it offers chemists, molecular and neurobiologists an insight into the ecological, evolutionary and behavioural context of olfactory communication.

This book was released on 2018-09 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant New Use - Rules on Certain Chemical Substances (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Significant New Use - Rules on Certain Chemical Substances (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 57 chemical substances which were the subject of premanufacture notices (PMNs). The applicable review periods for the PMNs submitted for these 57 chemical substances all ended prior to June 22, 2016 (i.e., the date on which President Obama signed into law the Frank R. Lautenberg Chemical Safety for the 21st Century Act which amends TSCA). Thirty-four of these chemical substances are subject to TSCA section 5(e) consent orders issued by EPA. This action requires persons who intend to manufacture (defined by statute to include import) or process any of these 57 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the intended use within the applicable review period. Manufacture and processing for the significant new use is unable to commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and take such actions as are required with that determination.
