Chapter 52 Guided Reading
1. Define the following terms: a. Population: localized group of individuals that belong to the same biological species
b. Density: number of individuals per unit or volume
c. Dispersion: pattern of spacing among individuals with geographic population boundaries.
d. Mark-recapture method: sampling technique used to estimate wildlife populations.
e. Immigration: influx of new individuals from other areas
f. Emigration: movement of individuals out of a population
g. Territoriality: behavior in which an animal defends a bounded physical space against encroachment by other individuals, usually of its own species
2. What are the three patterns of dispersion and what conclusions can you draw from these patterns?
The three patterns of dispersion are clumped, uniform, and random. Clumped is when animals live in groups increasing the effectiveness of hunting, spreads the work of protecting and caring for the young. It helps them exclude other individuals from their territory. Uniform is evenly spaced, pattern of dispersion may result from direct interactions between individuals in the population. Random dispersion occurs in the absence of strong attractions or repulsions among individuals of a population.
3. Define the following terms: a. Demography: study of the statistics relating to births and deaths of a population
b. Life tables: table of data summarizing mortality in a population
c. Survivorship curves: plot of the number of members of a cohort that are still alive at each age
d. Reproductive table: age-specific summary of the reproductive rates in a population
e. Life history: series of events from birth through reproduction and death
