- The secrets of sand : a journey into the amazing microscopic world of sand / by Greenberg, Gary,1944-author,photographer.; Kiely, Carol,author,photographer.; Clover, Kate,author,photographer.;
"From the beach to the moon--explore the incredible hidden world of sand, seen through a microscope.To the naked eye, the tiny particles that make up sand are less than inspiring. Under the microscope, however, it's a completely different story. Looking at sand under extreme magnification, we quickly find ourselves immersed in a new world of brilliant colors, organic shapes, and the stunning patterns of nature.Every grain of sand is a snapshot in time: Each grain originated somewhere and is headed somewhere else. Biogenic sands often contain fragments of the hard tissues from marine organisms such as shells, corals, sponges, sea urchins, forams, and bryozoans. When these organisms die, the hard tissues that are left behind erode into some of the most spectacular grains of sand imaginable. In this book, deep-focus microscope photography, x-ray images, and high-resolution scanning electron microscopy reveal their secrets.The Secrets of Sand is a virtual tour of sands from across North America. It shows their origins, the environmental forces that have acted upon them, and their journey from bedrock or invertebrate shell to the fine particles that, in countless billions, form our familiar beaches and dunes. It then moves on to an exploration of lunar sand, which has been formed under such alien conditions that it has no terrestrial counterpart. The Secrets of Sand is an amazing voyage of discovery in the ancient past--and the dynamic present--of the earth and our nearest neighbor"--- Subjects: Sand; Sand; Sand; Sand;

- A generic revision and phylogenetic analysis of the Primnoidae (Cnidaria:Octocorallia) / by Cairns, Stephen D.(Stephen Douglas),1949-(CARDINAL)290584; Bayer, Frederick M.(CARDINAL)286977; Smithsonian Institution.(CARDINAL)141176;
Includes bibliographical references (pages [67]-72) and index.Material and methods -- Results and discussion of character evolution and the evolutionary tree -- Systematic accounts."Primnoidae consists of 36 genera, 7 subgenera, and 233 valid species, making it the fourth largest octocorallian family. Species occur in all ocean basins, especially the Antarctic, at depths of 8-5850 m, making primnoids the deepest-living gorgonacean octocorals. Primnoids are common and characteristic of seamounts and deepwater coral banks, often providing habitat for other marine life and serving as proxies for isotopic analyses to determine paleotemperatures. Diagnoses of the primnoid genera and subgenera are based primarily on their type species, and specimens are illustrated by means of scanning electron microscopy, often using stereo images to allow better appreciation of the topology and interconnection of the calycular sclerites. A history of the higher classification of the family is given. Each genus is briefly discussed, and also included are a synonymy of pertinent references, a summary of the geographic and bathymetric ranges, and the deposition of the type specimens of the type species. Four new genera, two new subgenera, one new species, and seven new combinations are proposed. A list of the 233 valid species and the 14 infraspecific taxa is provided along with the purported junior synonyms. An indented dichotomous key is provided for identification of the genera and subgenera. Phylogenetic analysis of the genera and subgenera was performed using 27 morphological characters comprising 94 character states. The cladogram does not consistently support the conventional arrangement of genera into five subfamilies, thus this classification is not followed herein. The origin of the primnoids is inferred to be from an ancestor living in the Antarctic."--Publisher's website.- Subjects: Primnoidae;
