Developments in Fish Telemetry
This volume includes 33 peer-reviewed papers presented at the Sixth Conference on Fish Telemetry held in Europe (Sesimbra, Portugal, 5-11 June 2005). The papers focus on migration and behaviour, species conservation and habitat rehabilitation, human impacts and fisheries, telemetry methodology and new technology. This book is aimed at scientists and engineers actively involved in aquatic telemetry projects.
Lampreys: Biology, Conservation and Control
The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.
Physiology and Ecology of Fish Migration
Among the roughly 30,000 species of fish, migratory species account for only 165 species, but most of them are very important fisheries resources. This book presents up-to-date innovative research results on the physiology and ecology of fish migration. It focuses on salmon, eels, lampreys, and bluefin tuna. The book examines migratory behavior, sp
Ecology of Marine Fish
Ecology of Marine Fish offers updated reviews of the current knowledge on the ecology of marine fish. This book is an all-inclusive reference on the diversity of marine fish, their behaviors, their role in marine food webs, as well as the human and environmental impacts on marine fish, such as pollutants and climate change. It takes a historical approach to discussing spatial and temporal patterns of fish populations and introduces the changing patterns of the present. Each chapter provides an in-depth review of the science behind marine fish populations and the methodological tools to study them. This book is an excellent resource for anyone in the fisheries sector, including scientists and researchers, fisheries managers, marine resource managers, marine biologists, fish farmers, marine ecologists, policy makers, leaders and regulators, operations researchers, as well as students and faculty studying marine fish ecology. - Provides the latest scientific research and developments in the field - Presents a wide scope of different methodological approaches useful for field studies - Includes information on the role of marine fish in food webs and the impacts of climate change
Rios de Portugal
O livro Rios de Portugal: Comunidades, Processos e Alterações surge num contexto em que se reconhece a grande importância dos rios para a sociedade e em que há um intenso desenvolvimento científico e técnico sobre os ecossistemas aquáticos em Portugal. Em 17 capítulos da autoria de diversos investigadores portugueses pretendeu-se cobrir as várias áreas de investigação ligadas aos rios. Assim, este livro começa pelos aspectos físicos fundamentais dos rios: a hidrologia e a sedimentologia. Seguem-se oito capítulos dedicados aos organismos aquáticos: algas, fungos e bactérias, vegetação aquática e ribeirinha, invertebrados, peixes, anfíbios e répteis, mamíferos, e aves. Os capítulos seguintes abordam as atividades antrópicas que causam fortes alterações na qualidade dos ecossistemas, a monitorização ecológica, e a restauração de setores degradados dos rios. O penúltimo capítulo diz respeito à última secção dos rios, antes do mar, os estuários. E finalmente o último capítulo aborda as fontes termo-minerais que estão também fortemente ligadas aos cursos de água.
Toward Sustainable Agricultural Systems in the 21st Century
In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental,...
