Iguanas are large, primeval-appearing animals that have always attracted considerable attention and scientific study. The 30 species of iguanas are today collectively referred to as iguanines, or the subfamily Iguaninae, of the lizard family Iguanidae. This book is the result of a symposium of worldwide scientists on the world's iguanas that was held at a joint meeting of the Society of the Study of Amphibians and Reptiles and The Herpetologist's League. Over 30 recognized experts submitted their studies of these interesting reptiles, and have published what was once unknown and unpublished information. This book was a leader in its time and still serves as a wonderful reference for scientist and student alike.

In what is certain to be the key reference on iguanas for years to come, some of the world's leading experts offer a clear and accessible account of the latest research on the evolution, behavioral ecology, and conservation of these highly visible and increasingly endangered creatures, much loved by professional herpetologists and hobbyists alike. The book begins with an introduction by noted iguana biologist Dr. Gordon Burghardt that examines the state of iguana research—past, present, and future—with an emphasis on social behavior. Three major sections follow, each opening with a synthesis by the volume editors, who survey the current status and likely future direction of investigations in the pertinent area. The first section focuses on different aspects of the taxonomic and morphological diversity of iguanas and includes a complete checklist of species. In the second section, contributors address the behavior and ecology of iguanas and provide compelling evidence that both may be far more complex than previously appreciated. The third and final section, highlighting the threats facing iguana populations today, describes the broad array of innovative conservation strategies that will be needed to help ensure their survival. Illustrated throughout with photographs, distribution maps, tables, and figures, this volume will be the definitive resource for anyone—professional or curious amateur—interested in iguanas.

Representing the culmination of years of exhaustive research, it is the purpose of these conclusive volumes to keep alive the growing interest in Wesleyan studies for the entire Christian church. -- Amazon.com.

El querer Cuidar el Medio Ambiente, es el poder cambiar a mejores condiciones de Calidad de Vida. Las personas de este planeta, comprenden que la Buena Calidad es realizar una actividad, lo mejor posible, aún en actividades que se creen simples como, barrer, cocinar, lubricar una pieza de la máquina, etc. Porque yo creo que la Buena Calidad está en todo lo que hacemos. Por eso considero que la Calidad empieza por las personas o por uno mismo, realizando un trabajo correctamente en materiales, tiempo y con un método estandarizado y que lo que se requiere para trabajar con Calidad es, QUERER HACERLO, claro que también es necesario Saber cómo hacerlo y para eso se requiere de la capacitación y se necesita Poder trabajar o sea tener las habilidades físicas y mentales para realizar una tarea determinada. No creo en lo que dicen muchas personas de que "ya no hay valores", sino que considero que los valores allí están, existen bajo todos los cielos estrellados, porque son Universales, y que somos nosotros los seres humanos los que no damos la talla, y no me curo en salud, porque los valores no se aprenden, podemos obtener las máximas calificaciones en asignaturas de Ética, pero ser malos ejemplos para otras personas, en nuestras acciones morales y nos verán como deshonestos, viciosos, mentirosos, etc. Porque los Valores no se enseñan ni se aprenden, sino que se viven. Ese es el propósito de este libro, concientizar mediante la cultura el Cuidado del Medio Ambiente en base a la Ética y los Valores.

Art historian David Craven presents a sustained and highly original interpretation of Diego Rivera's particular version of "epic modernism," while offering a probing and coherent account of the artist's lifelong political activism. Drawing on both new primary documents and the best of recent secondary literature, Craven considers what Rivera's work in the public sphere has come to signify, and examines the artist's ongoing legacy for "post-colonial" discourse ; The study features a careful formal analysis of Rivera's most important paintings. Besides addressing his rediscovery of pre-Columbian art, Craven analyzes the artist's use of narrative, iconographic programs and the fresco technique for most well-known mural cycles, which continued to draw structurally on his early avant-garde work
