Raven 9 th Edition Ch 60 Guided Reading: Conservation Biology 60.1 1. Give 2 examples of how the threat of extinction around the globe is increasing. 20% of the world’s biodiversity may be lost because of the rapid and accelerating loss of habitat. Hunting endangered species may also threaten the extinction around the globe. 2. Define ENDEMIC: Plant or animal native and restricted to a certain area 3. What is a “hotspot” and give 2 ways humans have affected them. A hotspot is an area that has a high endemism and are disappearing at a rapid rate. Population pressure is a cause of habitat destruction in hotspots. Hotspots in more affluent countries are often at risk because they occur in areas where land has great value for real estate and commercial purposes. 60.2 4. Define “direct economic value” of biodiversity and give one specific example of what would happen if we lost a species of direct economic value. Direct economic value of products we obtain from species of plants and animals is a reason that biodiversity is valuable to us. If we lost a direct economic value species, the genetic variation will strain. 5. Define “indirect economic value” of biodiversity and give one specific example of what would happen if we lost a species of indirect economic value. Indirect economic value of benefits produced by species without our consuming them is why the biodiversity is valuable. The diverse biological communities are a vital importance to healthy ecosystems. Without it, the ecosystem wouldnt prevent the loss of minerals and nutrients. 6. Define “ethical and aesthetic value” of biodiversity and give one specific example of what would happen if we lost a species of ethical or aesthetic value. preserving biodiversity is an ethical issue because every species is of value in its own right, even if humans are not able to exploit or benefit from it. Almost no one would deny the aesthetic value of biodi- versity—a wild mountain range, a beautiful flower, or a noble elephant. If there was a species of ethical or aesthetic value that was lost due to human activity there would be sense of lost responsibility as the guardians or stewards of the diversity of life.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
