Document Summary
Questions from last lecture: draw hypothetical age structure for growing, declining, and stable populations, the two axes: age vs. % of the population in different age classes, growing population, many young individuals, declining populations; Survivorship: number of individuals alive from the initial number of. Individuals (here, that is 16: need initial number (16) - and then we compare individuals at each time. Survivorship for adults - 8/16 (0. 5: to calculate net reproductive rate: Sum of lxbx for each age: pups: 0 x 1 = 0, adults: . 5 x 3 = 1. 5. If reproducing early - the population will grow quicker: (short generation time - which is the denominator. The smaller the number, the higher the rate of increase) Increasing net reproductive rate: will increase the rate of increase of the population, decreasing generation time, also increases the rate of increase of the population***
