Document Summary

Prob: how can we study whether populations are changing: count all individuals of each age class in the population (=age distribution) Info on life expectancy survival to reproductive age. Cohort life table follow a cohort of indiv over time, recording deaths; difficult (length, tracking moving) Static life table based on age structure, record # indiv who died in each age class; need good records. Survivorship curves summarizes pattern of survival in a population. Type i high juvenile survivorship high, most mortality at older age, high parental care, few offspring (humans) Type ii constant, birds, die at equal rates, regardless of age. Type iii die at high rate as juveniles, lower rates later, low parental care, many offspring, perennial. Influences life history describes how over a lifetime, efforts are allocated to functions such as: growth, # offspring produced. Parental investment in offspring: size at reproductive maturity, dispersal. Influences timing of reprod b/c available energy is limited .
