eagle and the peregrine falcon from near-extinction in the United States
• boll weevil. CORRECT ANSWER: This routinely killed half of the cotton crop
from Texas to Georgia
• Natural selection. CORRECT ANSWER: the differential success (survival &
reproduction) of individuals within the population that results from their
interaction with their environment
• 3 conditions of evolution by natural selection. CORRECT ANSWER: 1)
Variation among individuals of heritable characteristics; must be able to pass on
trait
2) Inheritance of that variation to offspring
3) The variation results in differences among individuals in fitness; i.e., differences
in survival and reproductive success of parent
• Allee effect. CORRECT ANSWER: reduction in reproduction or survival of a
species when at low-population densities
• Integrated Pest Management. CORRECT ANSWER: The effective combination
of three types of pest control to manage pest populations while minimizing
environmental damage
,Do not need to totally eradicate pest populations...
