With about 10,000 species living in salted and brackish waters, foraminifera constitute the most diverse group ofshelled microorganisms in modern oceans, and substantially contrbute to biodiversity. Abundant and sensitive toenvironmental conditions, they constitute one of the most valuable tools for environmental assessment and moni-toring programs. Preservation oftheir mineralized test in the sediment allows the reconstruction of past conditions,including Global Change. This book gives an introduction to foraminifera, designed to be accessible to non-specialists, and summarize themain researches that have been carried out on foraminifera from New Caledonia.The main part of the guide descri-bes and illustrates more than 1,000 species of foraminifera collected in a great variety of environments around NewCaledonia. For each species, SEM micrographs are associated with a description and notes on its distribution. Inorder to facilitate identification, even by non-specialists, species are recorded in alphabetical order within groupsmade on the basis of (1) the nature of the test and (2) the dominant morphological feature. A photographical sum-mary is provided for preliminary identification.

Sedimentary habitats cover the vast majority of the ocean floor and constitute the largest ecosystem on Earth. These systems supply fundamental services to human beings, such as food production and nutrient recycling. It is well known that meiofauna are an abundant and ubiquitous component of sediments, even though their biodiversity and importance in marine ecosystem functioning remain to be fully investigated. In this book, the meiofaunal biodiversity trends in marine habitats worldwide are documented, along with the collection of empirical evidence on their role in ecosystem services, such as the production, consumption, and decomposition of organic matter, and energy transfer to higher and lower trophic levels. Meiofaunal activities, like feeding and bioturbation, induce changes in several physico-chemical and biological properties of sediments, and might increase the resilience of the benthic ecosystem processes that are essential for the supply of ecosystem goods and services required by humans. As a key component of marine habitats, the taxonomical and functional aspects of the meiofaunal community are also used for the ecological assessment of the sediments’ quality status, providing important information on the anthropogenic impact of benthos.

Bidong Island is a small island located in the South China Sea, and is about 14 km from mainland Peninsular Malaysia. The island and the Bidong archipelago boast of its richness in diversity of both terrestrial and marine organisms and its undeniably pristine and thriving ecosystem. In 1975–1990, Bidong Island was formerly a UNHCR refugee camp for a quarter of a million Vietnamese "Boat people" escaping the Vietnam War, and still holds great significance to many of its descendants. Due to its historical significance, the Terengganu State government plans to develop Bidong Island as a heritage tourism site and a new scuba diving destination. This book highlights the uniqueness of Bidong Island and its archipelago, paying particular attention to the biological aspect (which includes marine and terrestrial organisms) and the pollution status surrounding the island. These mainly focus on organisms of the open water and benthic ecosystems such as plankton, fishes, corals reef communities, crustaceans and foraminifera. In addition, we discuss terrene related topics, which includes tree diversity, lichens and also herpetofauna surrounding the Bidong Island. Indisputably an important topic, we also address the pollution status surrounding Bidong Island, with emphasis on heavy metals and its impact. Readers interested in the areas of environmental sciences should find this book appealing. This book can also be used by students and researchers when discussing about tropical environments on island ecosystems. We do hope that stakeholders that would partake in future interest of Bidong Island (particularly in tourism) are equally aware of the current health status of the island and would engage in conserving and sustaining the diversity and heritage of the archipelago for the benefit of the community.

This unique book provides a concise account of Indian Paleogene and presents a unified view of the Paleogene sequences of India. The Paleogene, comprising the early part of the Cenozoic Era, was the most dynamic period in the Earth’s history with profound changes in the biosphere and geosphere. The period spans ~42 million years, beginning from post- K/T mass extinction event at ~65 Ma and ending at ~23 Ma, when the first Antarctic ice sheet appeared in the Southern Hemisphere. The early Paleogene (Paleocene–Eocene) has been considered a globally warm period, superimposed on which were several transient hyperthermal events of extreme warmth. Of these, the Palaeocene Eocene Thermal Maxima (PETM) boundary interval is the most prominent extreme warming episode, lasting 200 Ka. PETM is characterized by 2–6‰ global negative carbon isotope excursion. The event coincided with the Benthic Extinction Event (BEE) in deep sea and Larger Foraminifera Turnover (LFT) in shallow seas. Rapid ~60–80 warming of high latitudinal regions led to major faunal and floral turnovers in continental, shallow-marine and deep-marine areas. The emergence and dispersal of mammals with modern characteristics, including Artiodactyls, Perissodactyls and Primates (APP), and the evolution and expansion of tropical vegetation are some of the significant features of the Paleogene warm world. In the Indian subcontinent, the beginning and end of the Paleogene was marked by various events that shaped the various physiographic features of the Indian subcontinent. The subcontinent lay within the equatorial zone during the earliest part of the Paleogene. Carbonaceous shale, coal and lignite deposits of early Eocene age (~55.5–52 Ma) on the western and north-eastern margins of the Indian subcontinent are rich in fossils and provide information on climate as well as the evolution and paleobiogeography of tropical biota. Indian Paleogene deposits in the India–Asia collision zone also provide information pertaining to the paleogeography and timing of collision. Indian Paleogene rocks are exposed in the Himalayan and Arakan mountains; Assam and the shelf basins of Kutch–Saurashtra, Western Rajasthan; Tiruchirappalli–Pondicherry and Andaman and, though aerially limited, these rocks bear geological evidence of immense importance.

Magnetic susceptibility (MS) is a tool frequently used by geologists on sediments or rocks to perform correlations and sea-level or climatic reconstructions. Applied measurements are made on unoriented, bulk samples and bulk MS is mostly influenced by the magnetic mineral content of the rock and often interpreted as influenced by detrital inputs. Magnetic data acquisition is fast and straightforward and this allows the high-resolution sampling needed for palaeoclimatic research (e.g. spectral analysis). However, the link with detrital inputs is not always preserved and the impact of diagenesis on the final MS signal can blur primary information. This volume includes contributions dealing with the origin of the magnetic minerals, and the application of MS as a palaeoenvironmental or palaeoclimatic proxy and also as a tool to provide astronomical calibration in order to improve the chronology of selected time intervals.

Conservation palaeobiology tracks the history of ecosystems based on the fossil record to guide conservation decisions and contribute to the theoretical foundations of conservation biology. The accelerating pace of global change requires better understanding of the long-term resilience and adaptive capacities of ecosystems. Fossil assemblages in outcrops and cores, together with surface accumulations of skeletal remains, represent unique archives of past ecosystem dynamics and baseline community states prior to anthropogenic impacts. However, as biological data retrieved from fossil and death assemblages cannot be treated in isolation, conservation palaeobiology integrates palaeontological and geological tools to account for the nature of the stratigraphic record. This volume brings together studies that demonstrate how combining marine palaeoecological records with other types of geohistorical data (taphonomic, sedimentological, geochronological, geochemical) can inform biodiversity conservation and ecosystem management. The papers highlight novel approaches and challenges in applying geohistorical data to conservation problems, discuss the limitations imposed by time averaging, and offer both deep- and near-time perspectives on conservation palaeobiology of marine ecosystems.

From the reviews: "This is now the definitive, authoritative text on applied foraminiferal micropaleontology and should be in the library of all practicing micropaleontologists." (William A. Berggren, Woods Hole Oceanographic Institution in Micropaleontology, 47:1 (2001)"During the last 20 years there has been an explosion of publications about foraminifera from an amazing variety of disciplines: basic cell biology, algal symbiosis, biomineralization, biogeography, ecology, pollution, chemical oceanography, geochemistry, paleoceanography, and geology. This book summarizes contributions by leading researchers in these diverse fields. It is not just another text on the biology of foraminifera. Rather, Barun Sen Gupta has accomplished his objective to "write an advanced text for university students that would also serve as a reference book for professionals"." (Howard J. Spero, University of California at Davis in Limnology and Oceanography, 45:8 (2000).
