More than 75% of endangered species in the United States rely on private lands for habitat. Although this habitat has long been regulated under the Endangered Species Act, there is now broad agreement that economic incentives are also needed for effective protection on private land. Many different mechanisms for incentive programs have been proposed and tested. For example, recovery credit syst...

To many people around the world, the conservation of endangered species is synonymous with the conservation of biodiversity. Ecologists, of course, understand that biodiversity encompasses far more than endangered species, but it is nonetheless true that endangered species are among the most visible and easily understood symbols of the ongoing loss of biodiversity (see Chapter 10). The protecti...

To the Editor:—As a junior faculty member committed to becoming an anesthesiology physician scientist, I read the article by Schwinn and Balser on recruiting and training more of my own with great interest. However, one issue not touched upon either in the article or in the accompanying Editorial View is that a large portion of recent anesthesiology graduates, including myself, do not hold US c...

Just 50 years ago, large herbivores like Banteng, Asian Elephant, and Eld’s Deer as well as predators like Indochinese tiger and leopard were so abundant in the Dry Forests of North and Northeast Cambodia that scientists compared this ecoregion to the savannas of East Africa. In the troubled decades that followed, however, habitat destruction and hunting greatly reduced animal numbers and diver...

The US Endangered Species Act is legislation with the power to limit human activities that may have deleterious effects on the viability of threatened and endangered species of fauna and flora. However, because most endangered species face multiple threats, it is often unclear whether limiting specific activities will improve the likelihood of long-term survival, particularly when the relative ...

Islands make up 5.3% of Earth’s land area yet maintain an estimated 19% of bird species, 17% of rodents, 17% of flowering plants, and 27% of human languages. Species diversity is disproportionately threatened on islands in relation to the islands’ proportion of both global land area and species, with 61% of all extinct species and 37% of all critically endangered species confined to islands. La...
