Species Concepts in Biology
Frank E. Zachos offers a comprehensive review of one of today’s most important and contentious issues in biology: the species problem. After setting the stage with key background information on the topic, the book provides a brief history of species concepts from antiquity to the Modern Synthesis, followed by a discussion of the ontological status of species with a focus on the individuality thesis and potential means of reconciling it with other philosophical approaches. More than 30 different species concepts found in the literature are presented in an annotated list, and the most important ones, including the Biological, Genetic, Evolutionary and different versions of the Phylogenetic Species Concept, are discussed in more detail. Specific questions addressed include the problem of asexual and prokaryotic species, intraspecific categories like subspecies and Evolutionarily Significant Units, and a potential solution to the species problem based on a hierarchical approach that distinguishes between ontological and operational species concepts. A full chapter is dedicated to the challenge of delimiting species by means of a discrete taxonomy in a continuous world of inherently fuzzy boundaries. Further, the book outlines the practical ramifications for ecology and evolutionary biology of how we define the species category, highlighting the danger of an apples and oranges problem if what we subsume under the same name (“species”) is in actuality a variety of different entities. A succinct summary chapter, glossary and annotated list of references round out the coverage, making the book essential reading for all biologists looking for an accessible introduction to the historical, philosophical and practical dimensions of the species problem.
Concepts of Biology
Instructors consistently ask for a textbook that helps students understand the relationships between the main concepts of biology, so they are not learning facts about biology in isolation. Mader’s Concepts of Biology was developed to fill this void. Organized around the main themes of biology, Concepts of Biology guides students to think conceptually about biology and the world around them. Just as the levels of biological organization flow from one level to the next, themes and topics in Concepts of Biology are tied to one another throughout the chapter, and between the chapters and parts. Combined with Dr. Mader’s hallmark writing style, exceptional art program, and pedagogical framework, difficult concepts become easier to understand and visualize, allowing students to focus on understanding how the concepts are related.
Basic Concepts in Biology
BASIC CONCEPTS IN BIOLOGY supplies a 650 page, introductory issues-oriented approach with enormous instructional power. This title has content identical to Starr's longer BIOLOGY, CONCEPTS AND APPLICATIONS, Sixth Edition, except for the omission of plant and animal physiology.The "Impacts, Issues" and "How Would You Vote?" features new to this edition make biology come alive. An "Impacts, Issues" case study opens each chapter focusing on a biology-related societal issue. Short films that expand on the issue are on the free Student CD. Each chapter's "How Would You Vote?" asks students to consider biology-related news, apply knowledge, cast a vote on the web and see voting tallies.The access codes that accompany all new copies provide online access to 1) BiologyNow, a learning tool that helps students assess their unique study needs through pretests, post-test and personalized learning plans; 2) InfoTrac, a library of full text articles; 3) vMentor, a live tutoring service and 4) "How Do I Prepare," a feature that allows students to review basic math, chemistry, and other skills that will help them more easily master introductory biology. And now with an MP3 download of this title, you don't have to lose prep time during a long commute-any MP3 player lets you or your students listen and review the text at the gym, in the library, at the office - anywhere!Starr is the most successful author in non-majors biology because of her clear and engaging writing, trend-setting art, and unparalleled student and instructor media.
