Book Description
Calcareous nannofossils are an exceptionally important microfossil group, with their living counterparts, coccolithopores, representing one of the major components of phytoplankton in present day oceans. Their abundant fossil record and world-wide distribution has led to their rapid acceptance as one of the most important index-fossil groups in stratigraphical research. The first two chapters of this book provide general information concerning calcareous nannofossils, including reviews of their biology and palaeobiology, and preparation and observation techniques. Chapters 3-9 are ordered stratigraphically, and present state-of-the-art summaries of calcareous nannofossil biostratigraphy for each time period, with comprehensive illustrations of all taxa within a standardised classification based on the latest research into structure and biomineralization. The practical application of these biostratigraphic schemes is discussed, including comments on zones biogeography, taxonomy and evolution. This information is internationally relevant, and global correlation is discussed. Calcareous Nannofossil Biostratigraphy is the most comprehensive atlas of this fossil group ever produced, containing 65 full page plates with over 2,000 individual photographs, together with comments concerning stratigraphic distribution and identification. Chapters on the Mesozoic contain electron microscope illustrations as well as light micrographs. The inclusion of much recent, previously unpublished, research provides a new level of biostratigraphic resolution for a number of time periods, making the book both a valuable synthesis and a significant step forward in biogeographical research. Calcareous Nannofossil Biostratigraphy is a comprehensive practical handbook for palaeontologists and organizations who use calcareous nannofossils in biostratigraphy, and provides a valuable practical reference work for earth scientists engaged in stratigraphic research, and those interested in palaeontology, palaeoceanography, stratigraphy and geochronology.

Book Description
This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume I covers the calcareous microfossils and includes planktic foraminifers, calcareous nannofossils and calpionellids.

Book Description
A compelling account of the extraordinary relatives of ordinary garden conifers. Leading expert Aljos Farjon provides a compelling narrative that observes conifers from the standpoint of the curious naturalist. It starts with the basic question of what conifers are and continues to explore their evolution, taxonomy, ecology, distribution, human uses, and issues of conservation. As the story unfolds many popular misconceptions are dispelled, such as the false notion that all conifers have cones. The extraordinary diversity of conifers begins to dawn as Farjon describes the diminutive creeping shrub Microcachrys tetragona, whose strange seed cones resemble raspberries, and the prehistoric-looking Araucaria meulleri. The taxonomic diversity of conifers is huge and Farjon goes on to relate how, over the course of 300 million years, these trees and shrubs have adapted to survive geological upheavals, climatic extremes, and formidable competition from flowering plants. All who seek to learn more about the early history of life on our planet will cherish this book.

Book Description
Natural history has always been the foundation of conservation biology. For centuries, botanists collected specimens in the field to understand plant diversity; now that many habitats are threatened, botanists have turned their focus to conservation, and, increasingly, they look to the collections of museums, herbaria, and botanical gardens for insight on developing informed management programs. Plant Conservation explores the value of these collections in light of contemporary biodiversity studies. Plant Conservation opens with a broad view of plant biodiversity and then considers evolutionary and taxonomic threats and consequences of habitat alteration; specific threats to plant diversity, such as invasive species and global climate change; consequences of plant population decline at the ecological, evolutionary, and taxonomic levels; and, finally, management strategies that protect plant biodiversity from further decline. With a unique perspective on biodiversity and scientific collections, Plant Conservation ultimately emphasizes the role museums and botanical gardens will play in future conservation.
