Flashcards in Chapter 19 Deck (22):
as defined in the US Endangered Species Act, a species that is in danger of extinction throughout all or a significant portion of its range
equilibrial life history
the pattern of reaching sexual maturity slowly and producing few offspring but caring for the young, often seen in long lived, large bodied species
exponential population growth
a model that describes the expansion of a population in an ideal unlimited environment
competition between individuals of same species for same limited resources
a non-native species that has spread far beyond the original point of introduction and causes environmental or economic damage by colonizing and dominating suitable habitats
the traits that affect an organism's schedule of reproduction and survival
in a population in which the fertility rate averages two children per female , the continuation of population growth as girls reach their reproductive years
a table which shows, for each age, what the probability is that a person of that age will die before his or her next birthday
the environmental factor that is of predominant importance in restricting the size of a population
Logistic Population Growth
the growth rate decreases as the population reaches carrying capacity
Opportunistic Life History
produce many young as early as possible, and provide no parental care
The number of a specific species in a given area
a measurement of population per unit area or unit; it is a quantity of type number in a given area
a graph showing the number or proportion of individuals surviving to each age for a given species or group
any species which are vulnerable to endangerment in the near future
The relative number of individuals of each age in a population.
The intentional release of a natural enemy to attack a pest population.
The maximum population size that a particular environment can sustain.
A limiting factor whose effects intensify with increasing population density.
A limiting factor whose occurrence and effects are not related to population density.
An estimate of the amount of land required to provide the raw materials an individual or population consumes, including food, fuel, water, housing and waste disposal.
