Document Summary
Sci301a, t, th (11-12), w (10-11) or by apt. Learning object: how ecology study populations and what the mathematical calculations can tell us. Consists of individuals of a species that interact with one another within a given area at a particular time. Population dynamics and how populations interact with their environment. Population densitynumber of individuals per unit area or volume is the population density. Age structure: the distribution of individuals across age categories. Comparing same population at different time points (1970 and 2000) Bottom heavy in 1970"s with lots of young individuals. As individuals age, they enter into primary reproductive years. More even distribution in the year 2000stabilization in population growth. Full census (count every individual) - good for large individuals with small numbers. Mark and recapture (tracking devices and artificial marks) - e. g. banding birds. A mathematical equation to describe a system. Used to predict rates and patterns of change.
