days early they cost$15, and when they are purchased With fewer breeding pairs, genetic variation shrinks.Monoculture, the agricultural method of growing a single crop, can also reduce genetic variation. d) The rest of the waste heat must be removed by evaporating water, either as perspiration or from the lungs. To clear a piece of land is to remove all trees and vegetation from it. For this reason, fewer offspring of inbred groups survive to maturity.Loss of genetic variation can occur naturally. was established to provide a means to conserve the ecosystems upon which endangered and threatened species depend, to provide a program for the conservation of these endangered and threatened species, and to take the appropriate steps that are necessary to bring any endangered or threatened .

Data Deficient: no assessment because of insufficient data. Too many zoos. More importantly, all living species, including people, depend on other species for survival. In 1988, the IUCN delisted the brown pelican. Inbred species do not have the genetic variation to develop resistance to the disease. A species is vulnerable if it is restricted to less than 1,000 mature individuals or an area of occupancy of less than 20 square kilometers (8 square miles).5) Probability of extinction in the wild is at least 10 percent within 100 years.Biologists, anthropologists, meteorologists, and other scientists have developed complex ways to determine a species probability of extinction.

This decline is measured over 10 years or three generations of the species, whichever is longer.A species is classified as critically endangered when its population has declined at least 90 percent and the cause of the decline is known. Many wild plant species could make important contributions to human food supplies, either as new crops or as a source of genetic material to provide disease resistance or other desirable traits to current domestic crops.
