Download or read book The Biology and Ecology of Giant Kelp Forests written by David R. Schiel and published by Univ of California Press. This book was released on 2015-05-01 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The largest seaweed, giant kelp (Macrocystis) is the fastest growing and most prolific of all plants found on earth. Growing from the seafloor and extending along the ocean surface in lush canopies, giant kelp provides an extensive vertical habitat in a largely two-dimensional seascape. It is the foundation for one of the most species-rich, productive, and widely distributed ecological communities in the world. Schiel and Foster’s scholarly review and synthesis take the reader from Darwin’s early observations to contemporary research, providing a historical perspective for the modern understanding of giant kelp evolution, biogeography, biology, and physiology. The authors furnish a comprehensive discussion of kelp species and forest ecology worldwide, with considerations of human uses and abuses, management and conservation, and the current and likely future impacts of global change. This volume promises to be the definitive treatise and reference on giant kelp and its forests for many years, and it will appeal to marine scientists and others who want a better appreciation and understanding of these wondrous forests of the sea.

This book was released on 1987 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven case studies are presented on commercial seaweed resources; five on wild crops, respectively Ascophyllum nodosum, Chondrus crispus, Gelidium, Laminaria longicruris and Macrocystis, are provided along with case studies of the farmed crops of Eucheuma and Laminaria japonica . Individually the cases range from descriptions of the wild crops and their management to the managed production of farmed crops including, in several examples, some information on economics and/or processing. These initial seven cases range from those emphasizing but one species from but one part of one country, to studies of a genus as it occurs commercially throughout the world.

Available in PDF, EPUB and Kindle. Book excerpt: This is a complete, systematic treatment of the marine algae (seaweeds) flora of California. The 726 species treated are each illustrated by a detailed line drawing made from an actual specimen. The two authors have drawn upon their phycological research to offer a definitive representation of benthic marine algae from the Californian coast. The floristic treatment in this first paperback edition should aid accurate and speedy identification of flora due to the improved keys, descriptions, illustrations and more detailed coverage of taxa, and should enhance the reader's knowledge of Californian macro-algae.
Download or read book The Effects of Rising Ocean Temperature and PCO2 on the Physiology and Growth of Giant Kelp Macrocystis Pyrifera and Grazing by Purple Urchins Strongylocentrotus Purpuratus written by and published by . This book was released on 2013 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate change rapidly alters the world's oceans, marine life will have to acclimate and/or adapt to warmer and more acidic conditions. While there is a growing body of literature on the individual effects of elevated temperature and CO2 on marine biota, few studies have examined the synergistic effects of these factors, especially regarding how they impact species interactions. In coastal environments of temperate latitudes, forests of kelp (large brown seaweeds in the Order Laminariales) provide habitat and food for numerous species, support enhanced biodiversity, and provide important ecosystem services. Consequently, impacts to these important ecosystem engineers can have disproportionately large effects on coastal ecosystem functioning. To determine how climate change might impact kelp forest ecosystems, I examined two of the more conspicuous and ecologically important kelp forest species, namely the giant kelp, Macrocystis pyrifera, and the purple sea urchin, Strongylocentrotus purpuratus. First, I performed three separate experiments in order to determine the effects of elevated temperature and pCO2 on M. pyrifera growth and photosynthetic performance. In my first experiment I cultured M. pyrifera meristematic tissues under three pCO2 levels (500, 1000, 1500 matm CO2) and examined how this impacted their growth, steady-state photosynthetic oxygen evolution, and changes in their tissue carbon:nitrogen ratios. In my second experiment, I used a fully factorial design with two temperatures (12°C and 15°C) and two pCO2 levels (500 matm and 1500 matm CO2), and examined how these impacted kelp growth, steady-state photosynthetic carbon uptake, and tissue carbon:nitrogen ratios. In my third experiment, I used the same fully factorial design (12°C and 15°C; 500 matm and 1500 matm CO2), but examined changes in kelp photosynthetic pigment composition and carbonic anhydrase activity (an estimate of their ability to use HCO3 - in photosynthesis). Counter to my expectations, elevating only pCO2 in the water had no effect on kelp growth rates, photosynthesis or tissue carbon:nitrogen ratios in either of the first two experiments. In contrast, in the second experiment, elevating only seawater temperature resulted in a significant reduction in both photosynthesis and growth, and an increase in tissue carbon:nitrogen ratios. However, when seawater temperature and pCO2 were increased together, the kelps exhibited significant increases in photosynthesis and growth relative to the other treatments. This suggested that rising ocean temperatures may interact with rising pCO2 to elicit responses that are different than when either of these factors is increased by itself. In my third experiment, elevating pCO2 in the water significantly reduced carbonic anhydrase activity, suggesting a reduction in HCO3 --based photosynthesis (i.e. a down regulation of carbon concentrating mechanisms) and an increase in CO2-based photosynthesis. In contrast, elevating temperature and/or CO2 alone had littleto- no impact on photosynthetic pigment concentrations. Following the experiments on M. pyrifera, I then examined how climate change will impact the interactions between S. purpuratus and M. pyrifera. Here, I cultured these two species separately under both "present day" conditions (i.e. 12°C and 500 matm CO2) and "future" conditions (i.e. 15°C and 1500 matm CO2) for three months. During this period, urchins were fed kelp from either their own water conditions or the alternate conditions, resulting in a fully factorial design with four treatment combinations (urchins held under either present day or future conditions being fed kelps grown under either present day or future conditions). My results indicate that urchins held under future conditions exhibited reduced feeding and growth rates, and smaller gonads than urchins held under present day conditions regardless of the conditions in which their food was grown. In contrast, urchins held under present day conditions and fed kelp grown under future conditions showed higher feeding and growth rates compared to similar urchins fed kelps grown under present day conditions. Together, my data suggest that M. pyrifera may benefit physiologically from a warmer, more acidic (i.e. higher pCO2) ocean while S. purpuratus will likely be impacted negatively. Given that S. purpuratus can exert a strong deterministic influence on M. pyrifera distribution and abundance, changes to either of their populations that might arise from climate change can alter how they interact and thus have serious consequences for many coastal environments.

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.
