This text examines the ecology of the Pacific salmon
Recent declines in the abundance of salmon in the Arctic-Yukon-Kuskokwim (AYK) region of western Alaska have created hardships for the people and communities who depend on this resource. In 2002, the AYK Sustainable Salmon Initiative (SSI) was created to undertake research to understand the reasons for this decline and to help support sustainable management in the region. This report makes recommendations for developing the research that the AYK SSI science plan should be based on, and relates the development of a restoration plan to the results of that research.
This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.
The U.N. predicts the Earth will have more than 9.6 billion people by 2050. With resources already scarce, how will we feed them all? Journalist Lisa Palmer has traveled the world for years, documenting the cutting-edge innovations of people and organizations on the front lines of fighting the food gap.
This book reviews the respiratory function of vertebrate red cells. I have defined the phrase "respiratory function" broadly to include, in addition to the actual oxygen and carbon dioxide transport, erythropoiesis, haemoglobin synthesis, red cell structure, the deformability of red cells in circulation, ion and substrate transport across the cell membrane, cellular metabolism, and control of cellular volume and pH. All of these aspects of the red cell function may affect gas transport between the respiratory epithelia and the tissues. Throughout the book, I have tried to relate our current knowledge about the nucleated red cell function to the wealth of information about the function of mammalian red cells. However, whenever possible, I have placed the emphasis on the nucleated red cell function for two reasons. First, the erythro cytes of 90% of vertebrate species are nucleated, and, second, nucleated red cell function has not been reviewed earlier in a single volume. This being the case, I have tried to make the reference list as complete as I could with regard to nucleated red cells. I hope that the approach adopted is useful for both com parative and human physiologists. Many people have contributed to the making of this book directly or in directly. Antti Soivio started me in this field. Prof. Henrik Wallgren has always encouraged fresh scientific ideas in his department. My present ideas of red cell function have been influenced by work carried out with Prof. Roy E.
Some issues addressed in this Working Group III volume are mitigation of greenhouse gas emissions, managing biological carbon reservoirs, geo-engineering, costing methods, and decision-making frameworks.
