1
Q

The chance that an individual at age X will survive to be age X+1.

A

survival rate

2
Q

The proportion of individuals that survive from birth (0) to age X.

A

survivorship

3
Q

The average number of offspring produced by a female while she is still of age X.

A

fecundity

4
Q

The fate of a group of individuals born during the same time period (cohort) is followed from birth to death.

A

cohort life table

5
Q

A graph based on survivorship data that plots the numbers of individuals from a hypothetical cohort that will survive to reach different ages.

A

survivorship curve

6
Q

A survivorship curve in which newborns, juveniles, and young adults all have high survival rates and death rates do not begin to increase greatly until old age.

A

type 1 survivorship curve

7
Q

A survivorship curve in which individuals experience a constant chance of surviving from one age to the next throughout their lives.

A

type 2 survivorship curve

8
Q

A survivorship curve in which individuals die at very high rates when they are young, but those that reach adulthood survive well later in life.

A

type 3 survivorship curve

9
Q

The proportions of the population in each age class.

A

age structure

10
Q

When the age structure of a population does not change from one year to the next.

A

stable age distribution

11
Q

Change in the size of a population of a species with discrete reproduction by a constant proportion from one discrete time period to the next.

A

geometric growth

12
Q

A constant proportion by which a population of a species with discrete reproduction changes in size from one discrete time period to the next; also called the finite rate of increase.

A

geometric population growth rate

13
Q

When a population of a species with continuous reproduction changes in size by a constant proportion at each instant in time.

A

exponential growth

14
Q

A constant proportion by which a population of a species with continuous reproduction changes in size at each instant in time; also called the intrinsic rate of increase.

A

exponential growth rate

15
Q

Of or referring to a factor that causes birth rates, death rates, or dispersal rates to change as the density of a population changes.

A

density-dependent

16
Q

Of or referring to a factor whose effects on birth and death rates are independent of population size.

A

density-independent

17
Q

When one or more density-dependent facts cause population size to increase when numbers are low and decrease when numbers are high.

A

population regulation

18
Q

A pattern in which abundance increases rapidly at first, then stabilizes at the carrying capacity.

A

logistic growth

19
Q

The maximum population size that can be supported indefinitely by the environment.

A

carrying capacity
