Excerpt from A Monograph of the British Fossil Corals: Part I. Introduction; Corals From the Tertiary Formations During this period Geology and Palaeontology have been very carefully studied, with the aid of all the accessories of modern scientific research. Many strata which had been considered almost unfossiliferous have been discovered to contain both known and unknown species, and those beds which yielded the specimens so admirably described and figured by the great French Zoophytologists have been successfully searched for others.

Excerpt from A Monograph of the British Fossil Corals, Vol. 1: Introduction, Corals From the Tertiary and Cretaceous Formations The basal or stalk-like Corals are in general well characterised by their dendroid form, compact tissue, and concentric layers. At first sight they may bear a slight resemblance to certain Bryozoa that have attained a very advanced age 1 but even then the remains of some non-obliterated cells will always enable an attentive observer to recognise the latter, and the absence of all trace of any such cavities can easily be ascertained, by grinding down or fracturing the stem of the above-mentioned Zoophytes. In some few instances these basal Polypidoms are more like the reticulated skeleton of certain foliaceous Spongidae but the concentric lamellae of their stern contrasting with the fibrous structure of the tissue of the Sponge, will still render them recognisable. Dermal Corals are in general characterised by features of a more striking aspect, and it is only when these Polypidoms are reduced to their most simple and degraded form, that they can be mistaken for the tegumentary skeleton of some of the lowest Bryozoa, or the reticulate, stony tissue of some highly-organized Spongidae. In all well-developed Corals of this kind, the central cavity or visceral chamber is more or less completely divided by a certain number of vertical plates, which project from its walls towards its axis, and produce that radiate structure which is so remarkable in the Astrean tribe. In most Bryozoa the mouth, or cephalic aperture of the tegumentary cell, is provided with a horny operculum,2 but no such organ ever exists in a true Coral; and, on the other hand, the radiate septa which we have just alluded to as being conspicuous in most Polypidoms, never exist in the cells of Bryozoa. The absence of an operculum, or of vertical septa, will not, however, enable the observer to decide whether the coral-like organic remains submitted to his investigation belong to the one or to the other of the two great zoological divisions, for it is a well-known fact that, in many of the inferior forms among recent Bryozoa, the tegumentary skeleton is reduced to a simple non-operculated tubular sheath, and that in certain Polypi (the Tubipora for example), no longitudinal septa are to be found; and the Polypidom is equally reduced to a calcareous tube, tapering and closed at its base, Open and more or less enlarged at its upper end.

Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

Classic Anthropology written by John William Bennett and has been published by Transaction Publishers this book supported file pdf, txt, epub, kindle and other format this book has been release on with Social Science categories.
Classic Anthropology is Bennett's label for the work produced by anthropologists during the period 1915-1955, which many believe represents the most productive era in the discipline's history. It is also one that can never be repeated, given the fact that most of anthropology's basic data - the ideas and customs of tribal peoples - have been extinguished or greatly transformed by modernization and nationalization. The book is composed of some fifteen essays. Among the issues examined are: the emergence of a functionalist viewpoint in ethnology; the difficulties of developing a theory of human behavior because of the focus on culture; the "search" for concepts of culture to serve specialized needs; the neglect of social psychology by the "culture and personality" field; how value judgments emerged, willy-nilly - or conversely, were neglected, in ethnological research; how applied anthropology was challenged by "Action Anthropology"; and how the interdisciplinary anthropology of the late 1940s was submerged in the postwar effort to return the discipline to traditionalroots. Individual anthropologists whose work is examined include, among others. Bronislaw Malinowski, Leslie Spier, Alfred Kroeber, Ralph Linton, Margaret Mead, Ruth Benedict, Clyde Kluckhohn, Gregory Bateson, and Walter Taylor.
