About 1998 Libro Consevation Biology
The number of degree-granting programs in conservation biology is on the rise and enrollments in conservation courses are skyrocketing. Many of our brightest undergraduate biology majors select conservation as their field of choice, and universities around the world are hiring so-called "conservation biologists." These are indications of a vigorous and healthy scientific field. But conservation biology as a science easily can be criticized. First of all, it is a field that is all too easily trivialized-made banal by the canonization of obvious "principles," such as large reserves are better than small reserves. It is also a field marked by subtle tensions between those who place a premium on actually solving problems, however mundane, and those who place a premium on the originality or cleverness of the problems they solve, however impractical. Finally, it is a field laden with alarmist half-truths and blatant exaggerations about crises. For example, the conservation biology literature is replete with "estimates" of extraordinary rates of extinction that read more like tabloid headlines than anything grounded in hard data. Extinction clearly is a major problem; however, we have little data documenting this fact. If conservation biology is to thrive, it must move beyond platitudes to solutions, it must resolve the tension between immediate applied questions and more farsighted basic research, and it must develop and maintain scientific credibility even though most of its practitioners have almost religious beliefs regarding issues such as the supreme importance of biodiversity. In this book we have attempted to unite new ideas under our vision of what is needed for conservation biology to meet its challenges. First, we have emphasized topics that are part of the daily activities of conservation biologists responsible for resource management. Thus, many chapters address restoration and invasions because a great deal of modem conservation involves recovering lost habitat and attempting to thwart exotic invaders. Similarly, several chapters touch on the mechanics of population viability analyses that are now a routine facet of single-species conservation efforts. Secondly, we have encouraged a "case history" approach because we are suspicious of broad generalizations and think much of practical importance can be learned by the details of real-world examples. Our last bias is the emphasis we place on quantitative analyses. It is our view that models and mathematical analyses can pinpoint limitations in existing data, and guide research towards aspects of biology that are most likely critical to the dynamics of a species or an ecosystem
