Many rare and endangered species are specialist. Explain what this term means. As an environment changes, should we worry about losing specialist? Why or why not?

The Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States.  There are now many success stories of animals/plants that were on the edge of extinction and now are returning.  Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.

To help preserve mountain biodiversity, it would be most helpful to reduce overgrazing reduce burning prevent oil production prohibit mineral extraction encourage use of off-road vehicles

Match the problems for biodiversity with the solutions described in the textbook.     Fund NGOs to implement conservation.    Charge visitors for admission and lodging.   Land managers have a responsibility to listen to local people's perspectives.   Train more scientists.   International organizations provide technical and financial support.   1. Many species remain undescribed. 2. Local people unsupportive of the conservation project. 3. Countries face pressure to develop their natural resources. 4. Budgets for conservation areas are inadequate. 5. Government bureaucracy can be inefficient.

A new species of toad is introduced into a region in a shipment of fruit, survives, and manages to start breeding. How could you determine whether the toad was an invasive species? You would need to determine whether it started breeding with native species. You would have to see if it was present over a large region or if it stayed in one location. All nonnative species are invasive species. O You would need to watch over time to see if it had a negative effect on other species. As it is now breeding in the area, it would be considered native and not invasive.
