Authoritative yet accessible, Human Biological Variation, Second Edition, opens with an engaging introduction to basic genetics and the evolutionary forces that set the stage for understanding human diversity. It goes on to offer a clear and detailed discussion of molecular genetics, including its uses and its relationship to anthropological and evolutionary models. The text features up-to-date discussions of classic genetic markers (blood groups, enzymes, and proteins) along with extensive background on DNA analysis and coverage of satellite DNA, single nucleotide polymorphisms (SNPs), and Alu inserts. It covers such current issues as the meaning and significance of "race," quantitative genetics and the "nature versus nurture" debates, biocultural interactions, population structure, and cultural and historical influences on patterns of human variation. Discussing the use of probability and statistics in studying human variation and adaptation in a lucid and approachable way, the book provides clearly explained math that is kept to the level of basic algebra.

Integrating real-world examples on interesting topics--including genetic testing, lactose intolerance, dyslexia, IQ, and homosexuality--the second edition of Human Biological Variation provides the most thorough and contemporary view of our biological diversity.

Markets have been found to be an increasingly important source of the seeds of crops and varieties low income farmers need to improve their livelihoods, encompassing both the formal and informal seed sector. Markets also have major impacts on agricultural biodiversity, by affecting farmers' choice of crops and varieties to grow. They are not, however, a homogenous institution, although all too frequently policies and regulations are developed as though they were. Markets vary considerably depending on the participants, on the institutions that govern how and what they exchange, and on local agricultural, economic and social conditions. Developing effective strategies to improve the way agricultural markets work, including how farmers use crop genetic resources, requires understanding of these variations. Seed Trade in Rural Markets presents a unique set of case studies from Bolivia, India, Kenya, Mali and Mexico on agricultural seed and product markets that describe three important market characteristics expected to affect farmers' access to seeds and varieties: the range of varieties on offer, the information provided about them, and relative prices. The case studies - all based around a common framework to aid comparability - also provide information on social, agricultural and economic factors which may be affecting the market availability, information, and cost of crop genetic resources, and ultimately the capacity to stimulate agricultural development Published with the Food and Agriculture Organization (FAO) of the United Nations

First published in 1983 to celebrate the centennial of the American Ornithologists' Union, Perspectives in Ornithology collects together a series of essays and commentaries by leading authorities about especially active areas of research on the biology of birds. Readers will find in this collection a useful overview of many major concepts and controversies in ornithology.
