what summarizes the probability that an individual will survive and reproduce in any given year over the course of its lifetime
life tables
what displays the general patterns in survivorship and makes comparisons amoung populations or species by ploting the number of survivors verses the age
survivorship curve
What has high survivorship while young then dramatically shifts to low survivorship when old
Type I
What has high survivorship when young and has a steady survivorship downwards as it gets older
