Book Description
Foraminifera are unicellular eukaryotes widespread in all marine environments. Modern benthic foraminifera own specific characteristics (i.e., high abundance, high diversity, easy to collect, well preserved) that make them good tools to highlight global and local environmental changes. Over the recent past the estuarine areas of the Hauts-de-France region, experienced differential degree of human disturbance. The principal objectives of this work are within this area, 1) to describe the benthic foraminiferal distributions and 2) to investigate their response to short- (annual and seasonal) and long-term (hundred years) environmental changes. This has been performed across both pristine and anthopogenized intertidal areas of the region. Faunal analyses have been coupled with sedimentological and geochemical analyses, to better understand the control of environmental parameters on driving spatial and temporal variations of benthic foraminifera. Different intertidal living foraminiferal assemblages are distinguished reflecting the main environmental drivers identified in the Hauts-de-France region. Long-term scale observations have allowed distinguishing both natural and human-induced environmental transformations through monitoring benthic foraminiferal changings. The study demonstrates the potential of foraminifera as bioindicators for application in environmental monitoring.

Book Description
This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Book Description
Environmental risks associated with large-scale marine finfish cage aquaculture cast doubt on the sustainability of the industry. This book divides the topic into its broad parts: Eutrophication; Sedimentation and Benthic Impacts; Changes in Trophic Structure and Function; and Managing Environmental Risks, and goes further to analyze methods and models currently used to measure near and far-field environmental effects of finfish mariculture and and their implications for management.

Book Description
Microfossils are ideally suited to environmental studies because their short generation times allow them to respond rapidly to environmental change. This book represents an assessment of the progress made in environmental micropalaeontology and sets out future research directions. The taxa studied are mainly foraminifera, but include arcellaceans, diatoms, dinoflagellates, and ostracodes. The papers themselves range from reviews of applications of particular taxa to specific case studies.

Book Description
Evolution and Geological Significance of Larger Benthic Foraminifera is a unique, comprehensive reference work on the larger benthic foraminifera. This second edition is substantially revised, including extensive re-analysis of the most recent work on Cenozoic forms. It provides documentation of the biostratigraphic ranges and palaeoecological significance of the larger foraminifera, which is essential for understanding many major oil-bearing sedimentary basins. In addition, it offers a palaeogeographic interpretation of the shallow marine late Palaeozoic to Cenozoic world. Marcelle K. BouDagher-Fadel collects and significantly adds to the information already published on the larger benthic foraminifera. New research in the Far East, the Middle East, South Africa, Tibet and Americas has provided fresh insights into the evolution and palaeographic significance of these vital reef-forming forms. With the aid of new and precise biostratigraphic dating, she presents revised phylogenies and ranges of the larger foraminifera. The book is illustrated throughout, with examples of different families and groups at the generic levels. Key species are discussed and their biostratigraphic ranges are depicted in comparative charts, which can be found at http://discovery.ucl.ac.uk/10047587/2/Charts.pdf.

Book Description
Measuring sea-level change – be that rise or fall – is one of the most pressing scientific goals of our time and requires robust scientific approaches and techniques. This Handbook aims to provide a practical guide to readers interested in this challenge, from the initial design of research approaches through to the practical issues of data collection and interpretation from a diverse range of coastal environments. Building on thirty years of international research, the Handbook comprises 38 chapters that are authored by leading experts from around the world. The Handbook will be an important resource to scientists interested and involved in understanding sea-level changes across a broad range of disciplines, policy makers wanting to appreciate our current state of knowledge of sea-level change over different timescales, and many teachers at the university level, as well as advanced-level undergraduates and postgraduate research students, wanting to learn more about sea-level change.

Book Description
The subjects refer to histories of ancient and modern use of seacoasts; possible macro-projects capable of massive changes in the coastlines of the Dead Sea, Red Sea and Persian Gulf caused by canal and massively scaled hydropower dam installations; relevant macro-projects for the Black Sea and Baltic Sea; possibilities of refreshment of the Aral Sea and Iran’s Lake Uremia with seawater or river freshwater importation macro-projects; potential rehabilitation of some vital arid zone regions now dominated by moving or movable surface granular materials using unique and unusual macro-projects; seawater flooding of land regions situated below present-day global sea-level; harnessing energy and obtaining freshwater from the world’s salt-laden ocean by modern industrial means; various macro-projects designed specifically for the protection (reduction of vulnerability) of particular Earth geographical regions.

Book Description
An editorial by Wanless (1982), entitled "Sea level is rising - so what?", tells the case of an executive editor of a major city newspaper, who, when confronted with evi dence for a recent sea-level rise, replied: "That just means the ocean is six inches deeper, doesn't it?". Whether his "so what?" attitude was real or put on to dike a threat of sensation, there is at present a wide and deepening interest in ongoing and future global sea-level change. This interest has grown along with the concern over global warming due to increasing levels of C02 and trace gases. A stage has been reached where investigators of climat- sea-level relationships call for long-term measurement programmes for ice-volume changes (using satellite altimetry) and changes in temperature and salinity of the oceans (ther mal expansion). This manual, however, is primarily concerned with sea level changes in the past, mainly since the end of the last glaciation. Its major objective is to help answer the ques tion: "how?", which, of course, is little else but to assist in the gathering of fuel for the burning question: "why?" Good fuel, hopefully, for the less smoke and ashes, and the more heat and light produced by that fire, the better scientists are enabled to develop a quantitative under standing of past, and hence of future, sea-level changes on different spatial and temporal scales.
