Download or read book The Feasibility of Bomb Radiocarbon Analysis to Support an Age at length Relationship for Red Abalone Haliotis Rufescens Swainson in Northern California written by and published by . This book was released on 2009 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of bomb generated radiocarbon (14C) changes in a red abalone, Haliotis rufescens Swainson shell was used to investigate age-at-length relationships derived from data from a previous multi-year, multi-site tag-recapture study. Shell carbonate was extracted from four successive growth trajectory locations in a single shell with a length of 251 mm MSL. Extraction locations were based on VBGF predictions and chosen to span the initial rise of the 14C-bomb pulse that is known to have occurred in surface ocean waters during 1958 ± 1 y in the northeast Pacific. The close temporal correspondence of the red abalone sample series to regional [Delta]14C records demonstrated the utility of the technique for validating age-at-length relationships for the red abalone. The findings provided support for a mean VBGF derived age of 32 y (range 30 to 33 y) for the specimen; however, the analysis of 14C data indicated that the specimen could be older.

Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of Biomedical Gerontology, Three Volume Set presents a wide range of topics, ranging from what happens in the body during aging, the reasons and mechanisms relating to those age-related changes, and their clinical, psychological and social modulators and determinants. The book covers the biological and medical aspects of gerontology within the general framework of the biological basis of assessing age, biological mechanisms of aging, age-related changes in biological systems, human age-related diseases, the biomedical practicality and impracticality of interventions, and finally, the ethics of intervention. Provides a ‘one-stop’ resource to information written by world-leading scholars in the field of biomedical gerontology Fills a critical gap of information in a field that has seen significant progress in the last 10 years

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance.Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins.With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Download or read book The Effects of Ocean Acidification and Upwelling Conditions on the Growth and Calcification of the Red Abalone Haliotis Rufescens written by Lauren White and published by . This book was released on 2011 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upwelling events along the California coast expose invertebrates to low dissolved oxygen simultaneously with high pCO2 levels that are progressively increasing as a result of rising atmospheric CO2. These multiple stressors could potentially impact the growth and calcification of economically valuable molluscs, such as abalone. To evaluate this threat, juvenile red abalone were maintained over a 4-week period in seawater undersaturated with respect to aragonite and containing 85% dissolved oxygen, which simulated an upwelling event. Seawater conditions were then returned to ambient levels for 3 weeks to determine the ability of the abalone to recover from the potential effects of low oxygen and high pCO2 conditions. Abalone exposed to the treatment had lower shell weights and calcium content per shell than abalone in the ambient group. Shells also appeared much lighter in color following the acidification period. After both groups were returned to ambient conditions, shells of the abalone in the treatment group still weighed less and had lower calcium content than the shells of the ambient group. The amount of weight gained by the abalone during the 3-week ambient period, however, was the same for both groups, suggesting an ability to recover a normal rate of weight gain after exposure. These findings suggest that juvenile red abalone experienced decreased net calcification following exposure to high CO2 and decreased DO. Though abalone were able to recover to normal growth rates, they were not able to accelerate their net calcification to catch up to the shells weights and calcium content of the ambient group, suggesting that they may have thinner or less dense shells following each upwelling event.
