This text provides an overview of what is meant by "biodiversity", and how we measure it. It reviews the different levels of biodiversity; population diversity; species diversity; community diversity; ecosystem diversity; landscape diversity; and historical and ecological biogeographic diversity. It also includes a brief discussion of diversity over geological time.
Exploring how our ancestors lived and how they died, the forty cases in this book tackle some of history’s most enduring questions and illustrate the power of science to reveal the secrets of the past.
When the Seas Rise takes us on an eye-opening journey from the dying coastal forests, where salt-killed tree trunks stand like sentinels of a retreating army, to the high tide-flooded streets of cities from St. Augustine to Key West. Meet the scientists at the University of Florida--researchers in biology, geology, entomology, horticulture, urban and regional planning, as well as other fields--who, along with other experts around the state, are planning for the sea change already upon us and the greater changes to come.
In May 1945, activists staged a "wade-in" at a whites-only beach in Miami, protesting the Jim Crow-era laws that denied blacks access to recreational waterfront areas. Pressured by protestors in this first postwar civil rights demonstration, the Dade County Commission ultimately designated the difficult-to-access Virginia Key as a beach for African Americans. The beach became vitally important to the community, offering a place to congregate with family and friends and to enjoy the natural wonders of the area. It was also a tangible victory in the continuing struggle for civil rights in public space.
