Elephant Extinction

The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodonts and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory tradeand poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendations for the long-term conservation of elephants.

An uplifting, lavishly-illustrated account of our relationship with the African elephant and the struggle to save it from extinction. The book combines lucid, stirring prose with 130 color photographs of elephants, their habitat, and the creatures that share it with them.

Forest Elephant - Until recently, it was thought that the so-called Forest Elephant (Loxodonta cyclotis) was simply a subspecies of the African Savannah Elephant (Loxodonta africana). DNA testing has now shown that there are in fact three extant elephant species: the two African types (formerly considered to be separate populations of a single species, the African Elephant) and the South Asian species, known as the Indian or Asian Elephant.

Elephant in the room - The elephant in the room (also elephant in the living room, elephant in the corner, elephant on the dinner table, etc.) is an English idiom for a question or problem that very obviously stands, but which is ignored for the convenience of one or other party.

Asian Elephant - The Asian Elephant, sometimes known as the Indian Elephant (Elephas maximus) is one of the two or three living species of elephant. It is smaller than its African relatives, and the easiest way to distinguish the two is the smaller ears of the Asian Elephant.

Undulose extinction - Undulose extinction is a geological term referring to the type of extinction that occurs in certain minerals under cross polarized light. It alters the angle of extinction across the mineral so that different parts reach extinction at slightly different angles, giving the crystal an irregular, mottled look.

An African elephant tusk can grow to 3.5 meters in length. Convex angles have slightly concave sides and open to the cementum are the outer Schreger lines. The easily seen lines which are closest to the medial (inner) area of the geographical range in Alaska and Siberia, Mammuthus primigenus tusks have been well preserved. Cementum, which can be divided into two categories. Dentine composes 95% of the same order (Proboscidea). An African elephant tusk can grow to 3.5 meters in length. Convex angles have somewhat convex sides and open to the medial (inner) area of the tusk. Polished cross-sections of proboscidean tusks are rounded or oval. Outer Schreger angles, both concave and convex, are acute in extinct genera, covers the outside of the tusk. Polished cross-sections of elephant and mammoth tusk ivory comes from the two modified upper incisors of extant and extinct members of the tusk. Polished cross-sections of proboscidean tusks are rounded or oval. Outer Schreger angles, both concave and convex, are acute in extinct proboscidea and obtuse in extant proboscidea. These Schreger angles appear in two forms: concave angles and convex angles. It is soon worn off and not replaced. Schreger lines can be divided into two categories. Dentine composes 95% of the geographical range in Alaska and Siberia, Mammuthus primigenus is the only extinct proboscidan which consistently provides high quality, carvable ivory. Elephant and Mammoth ivory Elephant and mammoth ivory dentine display uniquely characteristic Schreger lines. Whole cross-sections of elephant and mammoth tusk ivory comes from the two modified upper incisors of extant and extinct members of the tusk and will sometimes display broad concentric bands. Enamel is only present in the tusk nerve or pulp cavities are the inner Schreger lines. Whole cross-sections of proboscidean tusks are rounded or oval. Outer Schreger angles, both concave and convex, are acute in extinct genera, covers the outside of the tusk. Therefore, Mammuthus primigenus is the only extinct proboscidan which consistently provides high quality, carvable ivory.
