5 Multiple choice questions
- 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.
- Species that migrate into an ecosystem or are deliberately or accidentally introduced into an ecosystem by humans.
- Plant species found in the early stages of succession that (1) grow close to the ground, (2) can establish large populations quickly under harsh conditions, and (3) have short lives.
- Generally fixed route along which waterfowl migrate from one area to another at certain seasons of the year.
- Wild species with so few individual survivors that the species could soon become extinct in all or most of its natural range.
5 True/False questions
species approach → Goal: to protect species from premature extinction.
Strategies: identify endangered species; protect critical habitats.
Tactics: legally protecting endangered species; propagating endangered species in captivity; reintroducing species back into suitable habitats.
wildlife management → Wildlife species that have actual or potential economic value to people.
rare species → Type of wild animal that people hunt or fish for, for sport and recreation and sometimes for food.
local extinction → Occurs when a species disappears from a part of its range but persists elsewhere.
biological extinction → Species no longer found anywhere on earth; forever.
