This updated and expanded A New Island Biogeography of the Sea of Cortés, first published nearly 20 years ago, integrates new and broader studies encompassing more taxa and more complete island coverage. The present synthesis provides a basis for further research and exploration in upcoming years of the biologically fascinating Sea of Cortés region. The Gulf region is increasingly being exploited, for its natural resources by way of marine fisheries, and for its stunning natural beauty by way of a burgeoning tourism industry. Further, the region's human population is increasing apace. It is appropriate, therefore, that this volume discusses these evolving circumstances, and the efforts of the Mexican government to regulate and manage them. The new Biogeography includes a section on the conservation issues in the Sea of Cortés, past accomplishments and conservation needs as yet outstanding. This book should be of strong interest to conservation biologists, ecologists, and evolutionary biologists more generally.

The drag on ships comes from movement through the water. There is a part that is analogous to the parasitic drag in aircraft, and a part that comes from creating the bow and stern waves—in some ways similar to the compressibility drag in aircraft that approach the speed of sound. Given that the density of water is more than 800 times that of air, speeds through the water are slower. Drag coefficients are specified differently for ships than for cars, trucks and airplanes. The relevant area is the total wetted area, and not the frontal projected area. Ships can be very efficient—the very powerful two-stroke diesels that power large container ships and tankers can be over 50% thermally efficient.
