Ecology: Concepts and Applications was written for students taking their first undergraduate course in ecology. The authors have assumed that students in this one-semester course have some knowledge of basic chemistry and mathematics and have had a course in general biology, which included introductions to evolution, physiology, and biological diversity.

Few plant species have had as much combined scientific, public, and political attention as exotic Tamarix spp (tamarisk, saltcedar), attracting the public eye in the early 2000's when widespread drought in the West corresponded to assertions that the introduced tree used as much water as whole cities. This edited volume contains 24 essays by 44 authors on the hybrid swarm that represents invasive tamarisk, including its biology, ecology, politics, history, management, and even the philosophical and ethical issues involved with designating a particular species as "good" or "bad". These works reflect the controversy that has arisen around its role in our ecosystems and what should (or should not) be done about it, particularly in the context of the release of a biological control agent. This is the first text to examine these many facets of this interesting plant with an engaging and sometimes surprising collection of written works from the most important researchers in the field, representing the full spectrum of scientific perspectives.

An Introduction to Conservation Biology is the only text designed for both aspiring conservation biologists and non-majors who are interested in this topical field, providing up-to-date perspectives on high-profile issues such as sustainable development, global warming, and strategies to save species on the verge of extinction. The book focuses successively on biological diversity and its value; threats to biological diversity; conservation at the population and species levels; protecting, managing and restoring ecosystems; and sustainable development. Each chapter is beautifully illustrated in full color with diverse examples from the current literature. Chapters begin with guiding conservation biology principles and end with study aids such as summaries, an annotated list of suggested readings, and discussion questions. Throughout, the authors maintain a focus on the active role that scientists, local people, conservation organizations, government, and the general public play in protecting biodiversity, even while providing for human needs.
