Essential of ecology 3rd edition

Under an international agreement, it is illegal to remove them from the wild without special permits. However, a number of these rare parrots are illegally captured, smuggled from their native habitats to the United States and Canada, and sold on the black market for thousands of dollars apiece.

During their trip, north many of the smuggled birds die from stress and poor care. An even worse threat for the scarlet macaw is the clear-cutting and fragmentation of much of its forest habitat, which is taking place at a rapid and increasing rate.

For these reasons, scarlet macaws and a number of other tropical bird species are threatened with extinction. Analysis exercise at the end of each chapter and additional Data Analysis exercises in the Supplements.

The chapters with review questions that include all chapter key terms in boldface This edition also introduces a new coauthor, Scott Spoolman, who worked as a contributing editor on this and other environmental science textbooks by Tyler Miller for more than 4 years.
