| Question | Answer |
|---|---|
| indirect use value | values provided by biodiversity that do not involve harvesting or destroying the resource (e.g., water quality, soil protection, recreation and education). Also known as public goods. |
| Direct use value | Value assigned o products, such as timber and animals, that are harvested. Also known as commodity value or private goods. |
| Option Value | Value of biodiversity in providing possible future benefits for human society (e.g., new medicine) |
| Discount Rate | Method for reducing the current value of a resource that is going to be used at some point in the future. |
| Existence value | The amount people are willing to pay to prevent species from going extinct, habitats from being destroyed, and genetic variation from being lost. |
| Beneficiary value or Bequest value | how much people are willing to pay to protect something of value for their own children and descendants, or for future generations. |
| Conservation | the act of protecting from loss or depletion |
| Population | Group of individuals that mate with one another and produce viable offspring |
| Species | Groups of individuals that are morphologically, biogeochemically, physiologically distinct from one another, OR cannot breed with individuals of other groups; can be one or more populations |
| Community | All the populations living and interacting within a particular geographic area make up a biological (or biotic) community |
| Ecosystem | The living organisms in a community together with their nonliving or abiotic environment make up an ecosystem. Large variation in scale |
| Ecosystem Function | The interactions between organisms and the physical environment, such as nutrient cycling, soil development, water budgeting, and flammability |
| What are the goals in conservation biology? | 1Doc't range of biodiversity 2Investigate human impacts on species, communities, ecosystems & ecosystem functns. 3Develop practical approaches to prevent extinction, maintain genetic variation, protect & restore biological communities & their assc functns |
| John Muir | Preservation ethic |
| Preservation ethic | a belief in the need to preserve wilderness areas for their intrinsic value. |
| Gifford Pinchot | Resource conservation ethic |
| Resource conservation ethic | A belief that natural resources should be used for the greatest good of the largest number of people for the longest time. |
| Aldo Leopold | Land ethic |
