Book Description
This book details the natural history of the plants and animals found in the Galapagos Islands. A list of the dominant plants according to vegetation zone is included. Of particular note is the discussion of the problems of colonisation by founding populations, biological evolution, and ecology, and of the evolutionary processes bringing about species diversity.

Book Description
Moths of the family Arctiidae, with their brilliant coloration, spectacular courtship rituals, and bizarre defenses, are wonders of the natural world. Unpalatable by virtue of secondary chemicals acquired from their hostplants, these moths advertise their defenses by their coloration and often mimic butterflies, wasps, bees, stinkbugs, and even cockroaches. They have ears with which they hear the echolocation of bats, and some answer with aposematic warnings, while some may jam the bats' sonar.This book, the first written on this fascinating group, documents how tiger moths and woolly bears-the adults and larvae of the Arctiidae-flourish in a world rife with predators, parasites, and competitors. The contributing authors' accounts, each written by a recognized expert in the field, weave together seminal studies on phylogeny and behavior, natural history, chemical communication, mate choice and sexual selection, chemical ecology, parasite-host relationships, self medication, animal orientation, predator-prey interactions, mimicry, adaptive coloration, speciation, biodiversity, and more.

Book Description
This is a synthesis of both previously published information and abundant new data derived from field studies on Galagos insects. The dynamics and patterns of the evolution, ecology and distribution of the entire insect fauna are presented in general. The core of the book is an account of the 495 species of insects in the smaller orders with detailed information on their distribution and bionomics.

Book Description
Bradt's fully illustrated wildlife guides focus on regions of the world particularly celebrated for their amazing and often unique species. With spectacular photography or exclusive watercolour drawings throughout, each visitors' guide provides an introduction to the region's principal flora and fauna alongside suggested wildlife itineraries, practical information on when to go and what to take and photography tips. Written in a deliberately engaging way, they offer something different from dry field guides, and will appeal to the interested layman as much as the wildlife devotee. Ideal as a lightweight companion to any wildlife trip they also make a handsome souvenir. The Pantanal of Brazil, Bolivia and Paraguay is South America's Serengeti: its wetlands are the largest on earth (they're half the size of France) and, in the dry season, crocodiles and storks jostle to gobble the last of the dying fish. Here, the continent's largest cat, the jaguar, lives alongside giant otters, anacondas and the world's largest parrot. A comprehensive introduction to the best place to watch wildlife in South America, and beautifully illustrated throughout, Bradt's Pantanal Wildlife is the only portable book to cover all the main wildlife groups while focussing exclusively on the Pantanal.Based in Argentina, James Lowen is a wildlife writer, editor, photographer and lecturer. He is editor of the only magazine to focus on birdwatching in Latin America.

Book Description
The term 'dispersal centre' literally refers to the place from which a dispersal process started. However, it also implies the location of a centre of diversity, frequently even a recent one, as well as the location of a preservation centre or refuge during regressive phases in less remoted periods of earth's history, and that of a possible speciation centre. The latter may have been the place of differentia tion of subspecies, or species, provided that the isolation period has been suffi ciently long. The term deliberately brings the dynamics to prominence which is inherent in the process of dispersal. This dynamics is neither properly recognized when considering ranges 'whose recent structures more or less force us to consider them ,as static entities' (DE LATTIN 1967, p. 16)*, nor adequately taken into account by systematic typology. Yet, it is, in fact, the change that takes place in a range, which is of great significance in evolutionary genetics. In the case of range regressions which may lead to a diminution or rupture of the range pattern according to the pressure of the endogenous or exogenous triggering factors, subsequently arising distribution obstacles may result in a geographical isolation of partial populations or popula tion parts. Their sufficiently long spatial and reproductive isolation and the allele loss resulting from the change of the population size promote a divergent develop ment.
