Question | Answer |
Population | Individuals of the same species in the same general area |
Density | How concentrated an area is populated |
Dispersion | Spacing of the population |
Mark-recapture method | Tag and release study |
Clumped | Individuals aggregated in patches |
Grain | Spacial variation of individual organisms |
Uniform | Evenly spaced population |
Random | Unpredictable pattern |
Biogeography | The study of the distribution of species |
Demography | Study of vital statistic that affect population size |
Age structure | Relative number of individuals in each stage |
Birthrate/fecundity | Number of offspring produced in a certain amount of time |
Death rate | Highest in first year and in old age |
Generation time | Average span between birth of individuals and birth of their offspring |
Sex Ratio | Proportion of individuals in each sex |
Life Tables | Life exectancy |
Cohort | Group of individuals of the same age |
Survivorship curve | Plot of members of a cohort and what ages they are alive at |
Semelparity | Live to grow, reproduce, and die |
Iteroparity | Live longer by investing in smaller groups of offspring |
Zero Population Growth (ZPG) | Birth rates = death rates |
Intrinsic rate of increase | Maximum population growth rate |
Carrying capacity | Maximum support an area can provide for a population |
Logistic Population Growth | Density from maximum population to zero as carrying capacity is reached |
K-Selected Population/equilibrium population | Density limit imposed by resources |
R-selected population/opportunistic population | Population density fluctuates |
Intraspecific competition | Individuals of the same species rely on limited resources |
Density-dependent factor | Intensifies as the population increases in size |
Density-independent factors | Unrelated to population size |
