The driving forces of natural selection leave their traces in the shapes of living creatures and their patterns of distribution. In this thoughtful and wide-ranging discussion of evolutionary process and adaptive response, Geerat Vermeij elucidates the general principles that underlie the great diversity of marine forms found in the world's great oceans.

Molecular studies reveal highly ordered geographic patterns in plant and animal distributions. The tropics illustrate these patterns of community immobilism leading to allopatric differentiation, as well as other patterns of mobilism, range expansion, and overlap of taxa. Integrating Earth history and biogeography, Molecular Panbiogeography of the Tropics is an alternative view of distributional history in which groups are older than suggested by fossils and fossil-calibrated molecular clocks. The author discusses possible causes for the endemism of high-level taxa in tropical America and Madagascar, and overlapping clades in South America, Africa, and Asia. The book concludes with a critique of adaptation by selection, founded on biogeography and recent work in genetics.

"Fundamentals of Biogeography presents an appealing introduction for students and all those interested in gaining a deeper understanding of key topics and debates within the fields of biogeography, ecology, and the environment. Revealing how life has been and is adapting to its biological and physical surroundings, Huggett stresses the role of ecological, historical, and human factors in fashioning animal and plant distributions, and explores how biogeography can inform conservation practice."--Jacket.

Concepts of Biogeography & Astronomy Course Description This is the suggested course sequence that allows one core area of science to be studied per semester. You can change the sequence of the semesters per the needs or interests of your student; materials for each semester are independent of one another to allow flexibility. Semester 1: Biogeography It has been said that our planet is really just an insignificant speck in a vast universe, but that's not true! In fact, the conditions for life found on Earth are supremely unique and make our life here comfortable. This despite the reality that the world around us is also tainted and in need of careful calibration to continue. This book opens a window to the spectacular environments found on our planet, from deserts to the tropics. Researcher and biologist Dr. Gary Parker brings his vast knowledge of ecology to a teaching setting, exploring and explaining ecosystems, population growth, habitats, adaptations, energy problems, and much more. Learn about insect control in California, why mammals have fur, and how sharks maintain “friendships” with small fish known as remora. Exploring the World Around You brings the varieties of our planet's habitats alive to the reader. Semester 2: Astronomy Think you know all there is to know about our solar system? You might be surprised at some of the amazing details that you find when you begin Exploring the World of Astronomy! From the rugged surface of the moon to the distant and mysterious constellations, this book provides an exciting educational tour for students of different ages and skill levels. Learn about a blue moon, the 400-year storm on Jupiter, and what is meant by “the zone of life.” Discussion ideas, questions, and research opportunities help expand this great resource on observational astronomy into an unforgettable educational course for middle school to high school students!
