Chapter 19 Flashcards
The intentional release of a natural enemy to attack a pest population
Biological control
The maximum population size that a particular environment can sustain
Carrying capacity
A limiting factor who’s affects intensify with increasing population density
Density-dependent factor
A limiting factor who’s occurrence effects are not related to population density
Density-independent factor
An estimate of the amount of land required to provide the raw materials an individual or a population consumes, including food, fuel, water, housing, and waste disposal
Ecological footprint
A species that is in danger of extinction throughout all or significant portion of its range
Endangered species
The pattern of reaching sexual maturity slowly and producing few offspring but caring for the young
Equilibrial life history
A model that describes the expansion of the population in an ideal unlimited environment
Exponential population growth
Competition between individuals of the same species for the same limited resources
Intraspecific competition
A non-native species that has spread far beyond the original point of introduction and causes environmental or economic damage
Invasive species
The traits that affect an organism’s schedule of reproduction and survival
Life history
A listing of survivals and deaths in a population in a particular time. And predictions of how long, on average, an individual of a given age will live
Life table
An environmental factor that restricts the number of individuals that can occupy a particular habitat
Limiting factor
A model that describes population growth that decreases as population size approaches carrying capacity
Logistic population growth
The pattern of reproducing when young and producing many offspring that receive little or no parental care
Opportunistic life history
