Amphibians of Ecuador, Volume IV is the final installment in a four-volume series that provides comprehensive, well-illustrated, and authoritative insights into the amphibian species of Ecuador, making it an invaluable resource for biologists, conservationists, and others. The series explores, in comprehensive detail, the cultural history and the rich amphibian diversity of Ecuador, providing a thorough review of biogeography, amphibian declines, and conservation. Volume IV specifically focuses in Phyllomedusidae, Leptodactylidae, Ceratophryidae, Hemiphractidae, Eleutherodactylidae, Centrolenidae, Gymnophiona, and Caudata. Characteristics of each species are listed, defined, and compared to similar other species. Reproductive behavior, where known, is described as are data on vocalizations, larvae and ontogenetic changes. Amphibian distributions are detailed and illustrated with physiographic maps with dots. The volume also addresses the declines, extinctions, and conservation status of each species, highlighting their occurrence in protected areas. Key Features: Provides detailed and comprehensive accounts for all species from Ecuador of Phyllomedusidae, Leptodactylidae, Ceratophryidae, Hemiphractidae, Eleutherodactylidae, Centrolenidae, Gymnophiona, and Caudata. An Addendum includes accounts of species described from 2023 to 2024. New data are incorporated for many species. Describes with full color maps the distribution of all known taxa. Includes information on the ecology, reproduction, and behavior of all taxa.
The book reports on the author’s original work to address the use of today’s state-of-the-art smartphones for human physical activity recognition. By exploiting the sensing, computing and communication capabilities currently available in these devices, the author developed a novel smartphone-based activity-recognition system, which takes into consideration all aspects of online human activity recognition, from experimental data collection, to machine learning algorithms and hardware implementation. The book also discusses and describes solutions to some of the challenges that arose during the development of this approach, such as real-time operation, high accuracy, low battery consumption and unobtrusiveness. It clearly shows that it is possible to perform real-time recognition of activities with high accuracy using current smartphone technologies. As well as a detailed description of the methods, this book also provides readers with a comprehensive review of the fundamental concepts in human activity recognition. It also gives an accurate analysis of the most influential works in the field and discusses them in detail. This thesis was supervised by both the Universitat Politècnica de Catalunya (primary institution) and University of Genoa (secondary institution) as part of the Erasmus Mundus Joint Doctorate in Interactive and Cognitive Environments.
This open access book is an original contribution to the knowledge on fishing and research associated with one of the most enigmatic fish of our seas: bluefin tuna, Thunnus thynnus (L.). Based on available evidence, it reconstructs the possible methods used to catch large spawners in the Strait of Gibraltar thousands of years ago and describes the much more recent overfishing that led to a great reduction in the catches of the trap fishery on the area and the disappearance of the northern European fisheries. It is the first book to relate the overfishing of juvenile fishes in certain areas to the decline of large spawners in other very distant areas, revealing one of the main underlying causes of this decline, which has remained a mystery to the fishing sector and scientists alike for over 50 years. This finding should serve to prevent similar cases from arising in the future.
