Book excerpt: Over the last two decades there has been increasing recognition that problems in oceanography and fisheries sciences and related marine areas are nearly all manifest in the spatio-temporal domain. Geographical Information Systems (GIS), the natural framework for spatial data handling, are being recognized as powerful tools with useful applications

Download or read book Geography in America at the Dawn of the 21st Century written by Gary L. Gaile and published by . This book was released on 2005 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geography in America at the Dawn of the 21st Century surveys American geographers' current research in their specialty areas and tracks trends and innovations in the many subfields of geography. As such, it is both a 'state of the discipline' assessment and a topical reference. It includes an introduction by the editors and 47 chapters, each on a specific specialty. The authors of each chapter were chosen by their specialty group of the American Association of Geographers (AAG). Based on a process of review and revision, the chapters in this volume have become truly representative of the recent scholarship of American geographers. While it focuses on work since 1990, it additionally includes related prior work and work by non-American geographers. The initial Geography in America was published in 1989 and has become a benchmark reference of American geographical research during the 1980s. This latest volume is completely new and features a preface written by the eminent geographer, Gilbert White.

Download or read book Geographic Variation in Behavior written by Susan A. Foster and published by Oxford University Press. This book was released on 1999-03-04 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.

Download or read book Spawning Site Selection and the Influence of Incubation Environment on Larval Success in Interior Fraser Coho written by Crystal Jane McRae and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat features have been shown to influence salmonid spawning site selection as well as the survival and growth of larval fish throughout incubation. Most studies have been conducted in coastal watersheds, however, and little is known regarding habitat features associated with spawning sites for interior populations of salmon. My study examined factors affecting spawning site selection and incubation success for a population of interior Fraser coho salmon (IFC) (Oncorhynchus kisutch), in McKinley Creek watershed, British Columbia. Ground surveys coupled with radio telemetry were used to identify spawning site locations. An information theoretic approach was used to examine the probability of spawning site use based on habitat features. Incubation of larval fish within in-stream artificial redds allowed for the assessment of survival and growth in different incubation environments. The spawning habitat use of IFC throughout the McKinley Creek watershed was more extensive than previously realized. Hyporheic conductivity, dissolved oxygen, temperature and specific discharge were the best indicators of spawning site selection. Despite significant differences in habitat variables between used and unused spawning sites, survival and growth of larval IFC did not differ between sites; maternal effects were greater than incubation habitat features. This study has provided critical information about spawning site selection and the incubation environment of IFC, and has contributed to the understanding of the influence of habitat features on salmonids in interior watersheds.

This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.
