Available in PDF, EPUB and Kindle. Book excerpt: Marine environments are known for their dynamic, unpredictable nature. Therefore, search behaviour is particularly important for marine animals. Despite this, movement patterns and search behaviour of marine animals, and particularly fish, are poorly known. Here I investigate some unanswered questions relating to the search behaviour of a predatory marine fish, the small-spotted catshark (Scyliorhinus canicula). This research uses a combination of field-based tracking and laboratory investigations to evaluate the development of search behaviour. In the wild both male and female adults exhibited movements resembling central place foraging. These movements were characterised by preferential use of core areas from which discrete excursions were made at particular times prior to return to the core area. Despite this, sex differences in movements were found. Females undertook relatively infrequent, mainly nocturnal, long range excursions whereas males made more frequent excursions of variable duration and extent throughout both the day and night. In the laboratory, movement patterns of juveniles were consistent with a simple random walk model of movement, regardless of prey distribution or density. The resulting foraging efficiencies were also similar irrespective of treatment. The movements of males in the wild also appeared to be consistent with a random walk model, although a truncated-power law was found to be a good fit to some of the step length data, with exponent values indicative of optimal L?vy-like behaviour. Behaviour switching between different movement patterns in relation to complex changes in prey availability and distribution appears likely. In contrast, the movements of adult females in the field showed some degree of determinism, resulting in poor agreement with random walk models. The results of learning experiments with juveniles in the laboratory suggest that small-spotted catsharks may be capable of developing spatial memory, and such learning may be important for the development of efficient search tactics. Given these findings, the importance of learning with regards to search behaviour in catsharks warrants further investigation.

Available in PDF, EPUB and Kindle. Book excerpt: This book is about the behaviour of teleosts, a well-defined, highly successful, taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are weH over 22000 living species of teleosts, including nearly all those of importance in com mercial fisheries and aquaculture. Teleosts are represented injust about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour is the primary interface between these effective survival machines and their environment: behavioural plasticity is one of the keys to their success. The study of animal behaviour has undergone revolutionary changes in the past decade under the dual impact of behavioural ecology and sociobiology. The modern body of theory provides quantitatively testable and experi mentaHy accessible hypotheses. Much current work in animal behaviour has concentrated on birds and mammals, animals with ostensibly more complex structure, physiology and behavioural capacity, but there is a growing body of information about the behaviour of fishes. There is now increasing awareness that the same ecological and evolutionary rules govern teleost fish, and that their behaviour is not just a simplified version of that seen in birds and mammals. The details of fish behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment.

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 Advances in Invertebrates and Fish Telemetry written by Jean Paul Lagardere and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a selection of the most significant papers presented at the Second Conference on Fish Telemetry in Europe in La Rochelle, France, in April 1997. The conference was attended by 100 scientists from 18 countries. The contributions are grouped under the following headings: Methodology and New Developments, Tagging Procedures, Behavioural and Physiological Ecology, Fish Migration, Stock Management and Conservation. Particular emphasis was put on tag miniaturisation, multiple functions and sampling strategies. Papers concerned the effects of tags on fish for consolidating behavioural or original physiological investigations noticeably more open to the marine environment. Methods were essentially applied to study the relationships between fish and their natural environment. Besides providing up-to-date information on the state of fish telemetry, the book illustrates the increase in spatial and temporal scales and the number of tracked fish which gives a statistical basis for field study in behavioural ecology.
Download or read book Perturbation Behavioural Feedbacks and Population Dynamics in Social Animals written by Daniel Oro and published by Oxford University Press. This book was released on 2020-03-26 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This novel, transdisciplinary work explains how perturbations (defined as strong disturbances or deviations to a system) can affect the population dynamics of social animals, including ourselves. Social responses to perturbations, especially dispersal processes, can also generate non-linear population dynamics, including the potential appearance of tipping points and critical population transitions, which can in turn lead to catastrophic shifts and collapses. The book describes the links between social behaviour (mainly the use of social information and social copying), and non-linear population dynamics at different spatial scales (local dynamics and meta-population dynamics), and their ecological and evolutionary consequences. Examples from the natural world illustrate each of the main themes (prospecting, habitat suitability, collective dispersal, and cultural evolution). Human warfare and conflict, referred to in several chapters together with quantitative and qualitative examples, is also viewed as a form of perturbation and represents a paradigmatic example of the rationale behind this book. This applicability to our own species is particularly timely, given increased interest in both ecosystem change, human migration, and the global refugee crisis. Perturbation, Behavioural Feedbacks, and Population Dynamics in Social Animals will appeal to applied, theoretical, and evolutionary ecologists, particularly those working on the population and behavioural ecology of any social animal including humans. Its overlap with the study of complexity will also ensure its relevance and use to scientists from other disciplines such as sociology, anthropology, physics, computational science, economics, and mathematics.

Download or read book Marine Mammals and Noise written by W. John Richardson and published by Academic Press. This book was released on 2013-10-22 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.
