Product Description: In 1982, it was discovered that the vast majority of stomach ulcers are caused by H. pylori, nasty little bacteria found in the gut. In spite of the evidence, it took the U.S. medical community ten years to accept this finding and change their treatment of ulcers...read more

Product Description: This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules...read more

A book blending evolution and trophic dynamics, taking into account recent advances in both behavioral and population ecology, is long overdue. A central objective of this book is to consider whether adaptive behavioral decisions on the individual organism level might tend to stabilize trophic interactions. A second major goal of the book is to explore the implications of presumably adaptive behaviors on trophic dynamics and the implications of trophic dynamics for the evolution of adaptive behaviors. All evolutionary biologists, ecologists, and behavioral ecologists should find this exciting volume essential reading.

Product Description: Estimating abundance of wildlife is an essential component of a wildlife research program, and a prerequisite for sound management. With the exception of a few highly mathematical volumes, there are no books on the subject for use by students and field workers...read more

Product Description: Birds as Monitors of Environmental Change looks at how bird populations are affected by pollutants, water quality, and other physical changes and how this scientific knowledge can help in predicting the effects of pollutants and other physical changes in the environment.

Product Description: Most organisms show substantial changes in size or morphology after they become independent of their parents and have to find their own food. Furthermore, the rate at which these changes occur generally depends on the amount of food they ingest...read more

Product Description: H. REMMERT Small populations are very often discussed, but there seems to be no general overview touching all the self-evident but norma,lly simply neglected problems connected with small populations. First, there are many very different types of organisms, and as every biologist should know, the problems of small populations are very different in different types of organisms...read more

Product Description: Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight...read more

Product Description: Hard to find

A history of the influential role of exotic animals cites their application as diplomatic gifts and royal treasures, sharing such tales as those about the organized Medici hunts that were aided by cheetahs, Josephine Bonaparte's black swan breeding practices, and William Randolph Hearst's private California preserve.

Product Description: Living things are constantly engaged in a struggle for existence, and ingenious devices for the purpose of self-preservation can be seen in all types of animal and plant life. However, nature also displays phenomena that are not related to survival or that seem clearly to violate the principle of self-preservation--particularly when organisms interact with one another...read more

Product Description: The collapse of many of the World’s fisheries continues to be of major concern and the enhancement of fish stocks through techniques such as ranching is of huge importance and interest across the globe. This important book, which contains fully peer reviewed and carefully edited papers from the 2nd International Symposium in Stock Enhancement and Sea Ranching is broadly divided into sections covering the following areas: The present situation of stock enhancement Seed quality and techniques for effective stocking Health management of hatchery stocks Methods for evaluating stocking effectiveness Population management in stock enhancement and sea ranching Management of stocked populations Ecological interactions with wild stocks Genetic management of hatchery and wild stocks Socio-economics of stock enhancement Case studies Stock Enhancement and Sea Ranching has been written and edited by some of the world’s foremost authorities in fisheries science and related areas and is essential reading for all fisheries scientists throughout the World...read more

Product Description: Surveying an area dense with conflicting observations and ideas, this volume vividly depicts the current state of knowledge as well as the great diversity of opinion in the field of population ecology. Ten papers by outstanding authorities focus on three main issues-the effects of environment and population density on population dynamics, the influence of animal behavior on population growth, and the possibilities of genetic feedback or short-term evolutionary change in control of animal populations...read more
