Riassunto

The largest land mammals are constrained in their activities by their large body size, a theme that is emphasized in this account of their general ecology. The book begins by raising the question as to why these once abundant and widely distributed 'megaherbivores' - elephants, rhinos, hippos and giraffes - have all but gone extinct, and ends by considering the implications of the answer for the conservation of the remaining populations. Existing megaherbivores are placed in the context of the more numerous species which occurred worldwide until the end of the last Ice Age, and knowledge of the ecology of surviving species is used to analyse the cause of the extinctions. The information and ideas contained in this book are of crucial importance to all concerned with halting the rapidly worsening conservation status of remaining elephant and rhinoceros species, and carries a wider message for those concerned with the ramifying effects of man on ecosystem processes. Graduate students and research scientists in ecology, conservation biology and wildlife management will find this book of value.

Descrizione del libro:

Owen-Smith's account of the ecology of the largest land mammals (elephants, rhinos, hippos and giraffes) emphasises the constraints resulting from their body size. Many important questions are raised. For example, why have these once abundant and widely distributed animals all but gone extinct?
