- a Species no longer found anywhere on earth; forever.
- b Manipulation of populations of wild species (especially game species) and their habitats for (1) human benefit, (2) the welfare of other species, and (3) the preservation of threatened and endangered wildlife species.
- c requires the federal government to protect actively each of the hundreds of species listed as endangered-regardless of the economic effect on the surrounding towns or region.
- d Process in which numerous new species evolve to fill vacant and new ecological niches in changed environments, usually after a mass extinction or mass depletion. Typically, this takes millions of years.

5 True/False questions
population viability analysis (PVA) → Estimate of the smallest number of individuals necessary to ensure the survival of a population in a region for a specified time period, typically ranging from decades to 100 years.
domesticated species → Wild species that is still abundant in its natural range but likely to become endangered because of a decline in numbers.
Lacey Act of 1900 → Convention on International Trade in Endangered Species. Lists (1) some 900 species that cannot be commercially traded as live specimens or wildlife products because they are in danger of extinction and (2) restricts international trade of 29,000 other species because they are at risk of being threatened.
endangered species → Wild species with so few individual survivors that the species could soon become extinct in all or most of its natural range.
instrumental value → Value of an organism, species, ecosystem, or the earth's biodiversity based on its existence, regardless of whether it has any usefulness to us.
