The most thorough treatment of lizards of the United States and Canada when first published in 1946, Handbook of Lizards has become a landmark among herpetologists and lizard specialists. Hobart M. Smith spent years compiling and organizing information on 136 species of lizards for this classic study. With more than 300 illustrations, including black-and-white photographs, labeled drawings, range maps, and illustrated keys, this volume serves as a still-relevant and convenient reference guide to the study of North American lizards. Darrel Frost, a prominent lizard specialist, provides a foreword for the 1995 paperback edition that underscores the work's relevance for herpetology today. In the first section, Smith covers in concise fashion the habits, life history, habitats, methods of collection and preservation, and structural features of lizards. The second section of the book considers each species under topics that are conveniently arranged for studying both living lizards and laboratory specimens: range, type, locality, size, color, scalation, recognition characters, habitat and habits, and references. Smith also discusses problems for further study and gives recommendations for special investigations of each species. The book concludes with an extensive bibliography.

This 1980 book considers the patterns of population fluctuations of animals and intraspecific social relations by means of comparative methods and discusses the evolution of population regulation mechanisms and social relations. The author proposes that parental care has evolved in environments in which it is difficult for the young to obtain food, whilst high fecundity has evolved in the opposite environment. He presents evidence from a wide range of organisms to argue that during evolution animals repeatedly face the 'choice' of two strategies - low fecundity combined with parental protection, or high fecundity - and that this choice determined the amplitude, regularity and associated main factors of population fluctuations as well as the main characteristics of social relations as expressed in group life or dispersed living involving territory. Although many examples are drawn from insects, with which the author is most familiar, mammal, birds and other animal groups are also examined in depth.

This study, first published in 1942, helped to revolutionize evolutionary biology by offering a new approach to taxonomic principles, and correlating the ideas and findings of modern systematics with those of other life disciplines. This book is one of the foundational documents of the Evolutionary Synthesis. It is the book in which Ernst Mayr pioneered his concept of species based chiefly on such biological factors as interbreeding and reproductive isolation, taking into account ecology, geography and life history. In the introduction to this edition, Mayr reflects on the place of this work in the subsequent history of his field.
