Download or read book Bangladesh II Climate Change Impacts Mitigation and Adaptation in Developing Countries written by Md. Nazrul Islam and published by Springer Nature. This book was released on 2021-08-03 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume aims to develop a framework for disaster and climate risk resilient livelihood system in Bangladesh using a policy oriented approach. It highlights the possible impacts of climate change on groundwater based irrigation in the country. Climate change is one of biggest challenges to society. It can lead to serious impacts on production, life and environment on a global scale. Higher temperatures and sea level rise will cause flooding and water salinity problems which will bring about negative effects on agriculture and high risks to industry and socio-economic systems in the future. Climate change will lead to many changes in global development and security especially energy, water, food, society, job, diplomacy, culture, economy and trade. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as: “Any change in climate over time, whether due to natural variability or as a result of human activity.” Global climate change has emerged as a key issue in both political and economic arenas. It is an increasingly questioned phenomenon, and progressive national governments around the world have started taking action to respond to these environmental concerns.

Download or read book The Japanese Sea Urchin Market written by Sunee C. Sonu and published by . This book was released on 2003 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sea urchins are harvested worldwide, the majority destined for the Japanese market. Japan is by far the world's largest importer and consumer of sea urchin roe. In 2002, Japan imported about 18,525 metric tons (mt) of live sea urchins and sea urchin roe valued at about 247 million dollars, an increase of more than ten-fold in volume and 12-fold in value from 1975. Much of this increase was due to good demand, decreased domestic harvest, and consequent rise in price for sea urchin roe. Fresh sea urchin roe was the dominant product imported into Japan, representing as much as 49 percent in value in 2002. The United States has become the largest supplier of fresh roe to Japan, providing over 45 percent in value and 39 percent in volume of the total. Differences in peak fishing seasons in Japan (spring through summer) and the United States (fall through spring) have benefitted U.S. exporters in marketing sea urchin roe to Japan. Japan was the world's largest harvester of sea urchins until 1984. Since 1987, Japanese harvests have declined steadily due mainly to declining stock abundance. The harvest in 2002 of 13,000 mt was less than half of the record high landings which occurred in 1969. From 1987 to 2001, landings in the United States have exceeded Japanese landings. In 2001, sea urchins were harvested in six states: Alaska (1,166 mt), Washington (344 mt), Oregon (571 mt), California (5,951 mt), Maine (4,491 mt), and Rhode Island (0.1 mt). Most fresh sea urchin roe are sold through auction at the Tokyo Central Wholesale Market. Although quality of roe is the most important factor in determining prices, total supply (domestic and imported roe) is also significant. In 2002, the highest price for imported roe occurred in January. High prices for Japanese roe occurred in January and September, reflecting the low availability of roe during these months. Japan regulates imports of sea urchin products with import tariffs. As the United States and Japan are signatories to the World Trade Organization (WTO), WTO tariffs apply to U.S. exports of sea urchin products: 7 percent for fresh, frozen, or salted sea urchin roe, and 10 percent for prepared or preserved products, including those in airtight containers. There is no tariff for live sea urchins. Tariff rates are calculated as a percentage of total cost, including insurance and freight. Sea urchin roe shipped from Los Angeles is considered to be the best in Japan's import market. The future market for sales of U.S. sea urchins to Japan depends to a large extent on Japanese sea urchin harvest. Because domestic harvest is not likely to increase in the short term, increased export of U.S. sea urchins and sea urchin roe has significant potential."--Executive summary.

Download or read book Neurotransmitters in Plant Signaling and Communication written by František Baluška and published by Springer Nature. This book was released on 2020-09-20 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive update on the recent developments concerning the role of plant neurotransmitters in signaling and communication. Physiological investigations over the past few decades have demonstrated that plants employ neurotransmitters in various signaling pathways. Plant-based neurotransmitters (serotonin, melatonin, dopamine, acetylcholine, and GABA) share biochemical similarities with those in animal systems in terms of their chemical nature and biochemical pathways. Plant–environment interaction associated with abiotic stress management, growth modulation, flowering, circadian rhythm, fruit ripening, and allelopathic interactions are a major focus of research in the field, and recent advances in genomic, trascriptomic, and metabolomic approaches have resulted in the deciphering of the molecular mechanisms associated with various neurotransmitters in plants. Other current and potential areas of investigation include the putative phytohormone phytomelatonin, and receptor-mediated signaling in plant neurotransmitters. Providing an up-to-date overview of molecular crosstalk mechanisms between various neurotransmitters, the book offers essential insights to help readers gain a better understanding of the physiology of plant signaling and communication with the environment.

Download or read book Body Size The Structure and Function of Aquatic Ecosystems written by Alan G. Hildrew and published by Cambridge University Press. This book was released on 2007-07-12 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

This book was released on 2011-03-23 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The bones recovered from the middens of the northeastern Pacific shorelines have important stories to tell biologists, marine mammalogists, and those concerned with marine conservation. This volume unearths a wealth of information about the historical ecology of seals, sea lions, and sea otters in the North Pacific that spans thousands of years. It provides fascinating insights into how the world once looked, and how it may one day look again as seals, sea lions, and sea otters reclaim and recolonize their former haunts.”—Andrew Trites, Director, Marine Mammal Research Unit, University of British Columbia “Braje and Rick have assembled a compelling set of case studies on the long-term and complex interactions between people, marine mammals, and environments in the Northeast Pacific. The promise of zooarchaeology as historical science is on full display, as researchers use geochemistry, aDNA, morphometrics, and traditional analytic methods to address questions of utmost importance to the long-term health of coastal ecosystems. If this book doesn't convince conservation biology about the need to take the long view of animal histories and ecosystems into account in developing conservation management plans, I'm not sure what will.”—Virginia L. Butler, Department of Anthropology, Portland State University
