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 Ethology and Behavioral Ecology of Sea Otters and Polar Bears written by Randall W. Davis and published by Springer. This book was released on 2022-07-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

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.

Download or read book Conservation for the Anthropocene Ocean written by Phillip S. Levin and published by Academic Press. This book was released on 2017-06-01 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation for the Anthropocene Ocean: Interdisciplinary Science in Support of Nature and People emphasizes strategies to better connect the practice of marine conservation with the needs and priorities of a growing global human population. It conceptualizes nature and people as part of shared ecosystems, with interdisciplinary methodologies and science-based applications for coupled sustainability. A central challenge facing conservation is the development of practical means for addressing the interconnectedness of ecosystem health and human well-being, advancing the fundamental interdisciplinary science that underlies conservation practice, and implementing this science in decisions to manage, preserve, and restore ocean ecosystems. Though humans have intentionally and unintentionally reshaped their environments for thousands of years, the scale and scope of human influence upon the oceans in the Anthropocene is unprecedented. Ocean science has increased our knowledge of the threats and impacts to ecological integrity, yet the unique scale and scope of changes increases uncertainty about responses of dynamic socio-ecological systems. Thus, to understand and protect the biodiversity of the ocean and ameliorate the negative impacts of ocean change on people, it is critical to understand human beliefs, values, behaviors, and impacts. Conversely, on a human-dominated planet, it is impossible to understand and address human well-being and chart a course for sustainable use of the oceans without understanding the implications of environmental change for human societies that depend on marine ecosystems and resources. This work therefore presents a timely, needed, and interdisciplinary approach to the conservation of our oceans. - Helps marine conservation scientists apply principles from oceanography, ecology, anthropology, economics, political science, and other natural and social sciences to manage and preserve marine biodiversity - Facilitates understanding of how and why social and environmental processes are coupled in the quest to achieve healthy and sustainable oceans - Uses a combination of expository material, practical approaches, and forward-looking theoretical discussions to enhance value for readers as they consider conservation research, management and planning

Download or read book The Freezing Season written by G. Norman Lippert and published by CreateSpace. This book was released on 2015-08-24 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ashley is a young woman broken by choices- some her own, some not. Looking to escape the haunting grip of her past, she embarks on a several-state winter road trip only to pass a sight that changes her life completely: jutting from a dirty snow bank, a small human hand holds its palm up to the sky. Driven by an uncharacteristic need for redemption, Ashley returns to investigate. There, she encounters a seemingly helpful, if disturbed local man and the county sheriff. It isn't until the sheriff begins to question Ashley that the terror of her situation dawns: the body in the snow isn't a snowplow accident, but a murder victim, and by coming back to investigate, Ashley has placed herself directly in the serial killers' path. As the next twenty-two hours unfold, Ashley is confronted with a terrible choice: take advantage of her one chance for escape, or attempt rescue of the killers' last remaining victim, possibly sacrificing herself in the process. Only by embracing the ghosts of her past will Ashley survive her descent into the disturbing madness of the freezing season.
