A comprehensive review of these two interesting and economically important desert succulents.

The result of one of the most detailed and careful examinations of the behavior and ecology of a vertebrate ever conducted in the wild, this study addresses one of the major questions in evolutionary biology: why do some populations vary so much in morphological, ecological, behavioral, and physiological traits? By documenting the full range of variation within one population of a species and investigating the causal factors, Rosemary and Peter Grant provide impressive evidence that species are capable of evolutionary change within observable periods of time. Among the most dramatic examples of recent speciation and adaptive diversification are Darwin's Finches, which live in the Galápagos Islands. Darwin theorized that these closely related birds had evolved from a common ancestor to fill the available ecological niches on this remote archipelago. Not only have they evolved into thirteen species, but more recent study has shown that many of them exhibit striking variation in beak structure and other traits. For more than a decade, the Grants have studied one of these species, the large cactus finch, on the isolated Isla Genovesa. They present information on the environment and demographic features of the population, then discuss the range of genetic, ecological, and behavioral factors responsible for the unusually large morphological variation. They place the large cactus finch in its community setting to better understand its evolution and conclude by discussing the implications of the study for the genetic structure of small populations and the problems of conserving them. They illustrate their findings with an array of drawings, tables, and photographs.

Observe the wondrous diversity of life, including birds, reptiles, and plants Learn how Darwin's worldview and the biblical worldview differ and the importance of this in studying the Galápagos With poignant chapters from Ken Ham, John Morris, John C. Whitcomb, Danny Faulkner, Gary Parker, and more! Where Darwin once visited and later used evidence from to support his faulty case for evolution, discover the wonder of God in this full-color book filled with vibrant images of these glorious islands in the Pacific, as well as powerful insights that give Him the glory due His name. Your faith will be strengthened as you learn the importance of a biblical worldview from some of the best apologetics speakers in the country. It's an overall emphasis on Galápagos as testament to God's majesty and mercy rather than the empty legacy of one man!

This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.​
