This book was released on 2017 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organisms shift between different ecological niches or habitats throughout their lives. These shifts are prompted by growth and changing resource needs. In the marine realm, understanding why and when fish shift habitats is particularly important due to the increasing use of spatial management as a conservation strategy. Effective spatial management requires understanding how a species habitat usage changes throughout its lifespan. Within the Southern California Bight (SCB)Yellowtail (Seriola lalandi) are iconic gamefish and widely targeted throughout the region, both in U.S. and Mexican territorial waters. Their cross-border movements mean these fish encounter a diverse array of anthropogenic pressures, ranging from ocean-warming to agricultural and urban run-off to significant recreational, artisanal, and commercial fishing. This work attempts to understand and quantify how yellowtail use the Southern California Bight and how that usage affects their biology. This was carried out in 3 separate chapters dealing with analysis of long-term recreational catch records, conventional tagging, passive acoustic telemetry as well as spatially-explicit analysis of age, growth, diet and trophic position. The primary differences detected across all investigated parameters were size-mediated. Thus, one contiguous population with distinct ontogenetic shifts in habitat and diet is the most parsimonious explanation for the results from each chapter presented in this thesis. Recreational catch data showed inshore and offshore catch sizes were different between years and across seasons and fish size, rather than tagging season best explained detection rates of acoustically tagged fish. These findings supported claims by recreational anglers that large fish caught inshore are potentially year-round SCB residents. The conclusion of one, panmictic, SCB yellowtail population is further supported by results from life-history analysis as fish size again was the only source of significant differences in age/growth, diet, or trophic position regardless of sampling location or region. Results from tag returns, acoustic telemetry and life-history analysis indicate that there is likely one contiguous population of yellowtail in the SCB and that due to high levels of fishing pressure, this population may be reliant on seasonal influxes of fish from the south to sustain current fishing levels.
Download or read book The Ecology of Marine Fishes written by Dr. Larry G. Allen and published by Univ of California Press. This book was released on 2006-02-15 with total page 1353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.

Download or read book Ecology of Australian Temperate Reefs written by Scoresby Shepherd and published by CSIRO PUBLISHING. This book was released on 2013-10-23 with total page 923 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Australian Temperate Reefs presents the current state of knowledge of the ecology of important elements of southern Australian sub-tidal reef flora and fauna, and the underlying ecological principles. Preliminary chapters describe the geological origin, oceanography and biogeography of southern Australia, including the transitional temperate regions toward the Abrolhos Islands in the west and to Sydney in the east. The book then explains the origin and evolution of the flora and fauna at geological time scales as Australia separated from Antarctica; the oceanography of the region, including principal currents, and interactions with on-shelf waters; and the ecology of particular species or species groups at different trophic levels, starting with algae, then the ecological principles on which communities are organised. Finally, conservation and management issues are discussed. Ecology of Australian Temperate Reefs is well illustrated with line drawings, figures and colour photographs showing the many species covered, and will be a much valued reference for biologists, undergraduates, and those interested and concerned with reef life and its natural history. 2014 Whitley Award Commendation for Marine Ecology.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
