This book was released on 2023-11-20 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last fifty years, human exploitation of marine resources has become more efficient as the understanding of the habits and behaviour of the various species available in the sea gradually increased. Thus, technologies have developed naturally over time and fishing gears and practices have become more sophisticated. These technical advances in fishing gear have generally led to more efficient economic fishing operations and better access to resources. However, fishing implies the harvesting of marine organisms directly from their natural environment, therefore general awareness of environmental problems due to the exploitation of fishery resources has also increased. In particular, the poor selectivity of some gears is responsible for the capture of juveniles, immature and undersized specimens of many species, with negative consequences on the state of stocks. In addition, bycatch in marine fisheries is a major source of human-caused mortality of marine megafauna, often leading to the capture of vulnerable species. Finally, many bottom-towed gears are responsible for high impacts on bottom communities and habitats, with cascading consequences on the entire marine ecosystem. All these impacts can lead to changes in the structure, function and integrity of ecosystems, including effects on the food webs and multispecies predator-prey relationships.

Download or read book Tools for Oceanography and Ecosystemic Modeling written by André Monaco and published by John Wiley & Sons. This book was released on 2016-07-14 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studying the Ocean Planet requires measuring and sampling instruments to feed models that take into account its complexity. This book presents the diversity of observation and monitoring techniques at various scales, but also different kinds of model that take into account some conceptual schemes incorporating various scientific knowledge. Sampling is approached via the efficiency of fishing gears; underwater acoustics is used to detect, count, identify and listen to live and mobile living resources. Bio-logging allows us to rely on the behavior of marine animals to help investigate environments that are difficult to sample by conventional means, while listing the physiological changes they undergo. Modeling is presented not only in a functional framework, but also in an exploratory design incorporating various scenarios for ecosystem changes under the pressure of global change. This ninth volume completes the "Seas and Oceans" Set that adopts a transversal approach leading to the governance and sustainable management of the marine environment.

Download or read book Protocols to Assess the Breakdown of Flushable Consumer Products written by Drew C. McAvoy and published by IWA Publishing. This book was released on 2003-07-31 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A scientifically sound approach is needed to ensure that flushable consumer products are compatible with household plumbing fixtures, as well as wastewater collection and treatment systems. In addition to assessing disposal system compatibility, an assessment approach should also ensure that flushable consumer products do not become an aesthetic nuisance in surface waters and soil environments. This document presents an overall approach for assessing the fate and compatibility of consumer products in wastewater disposal systems. While the focus of this document is on the United States, it is believed that the conceptual approach and many of the test methods could be used to assess the compatibility of flushable consumer products in wastewater disposal systems throughout the world.

Download or read book Developing a Protocol for Observational Comparative Effectiveness Research A User s Guide written by Agency for Health Care Research and Quality (U.S.) and published by Government Printing Office. This book was released on 2013-02-21 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This User’s Guide is a resource for investigators and stakeholders who develop and review observational comparative effectiveness research protocols. It explains how to (1) identify key considerations and best practices for research design; (2) build a protocol based on these standards and best practices; and (3) judge the adequacy and completeness of a protocol. Eleven chapters cover all aspects of research design, including: developing study objectives, defining and refining study questions, addressing the heterogeneity of treatment effect, characterizing exposure, selecting a comparator, defining and measuring outcomes, and identifying optimal data sources. Checklists of guidance and key considerations for protocols are provided at the end of each chapter. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews. More more information, please consult the Agency website: www.effectivehealthcare.ahrq.gov)
