A
Line that shows survival rate of a cohort in a population from birth to death
2
Q
Cohort
A
group of same-aged individuals
3
Q
Type 1
A
- High survivorship in early life sure to high parental care
- High survivorship in middle-life due to large size and defensive behavior
ex: Most Mammals
(K-Selected)
4
Q
Type 2
A
Steadily decreasing survivorship throughout their lives
Ex: Birds and Mice
5
Q
Type 3
A
- High mortality early in life due to little parental care
- Few make it to midlife; slow, steady decline in survivorship in mid life
ex: insects, fish, plants
(R-selected)
