Survivorship Curves

Growth Curves

Life History Types – K selected Late reproduction Long life span Low mortality rate Extensive parental care Greater investment in maintenance and survival of adults At or near carrying capacity Examples include lions and elephants

Life History Types – r selected Early reproduction Short life span High mortality rate Little or no parental care Large investment in producing large numbers of offspring Below carrying capacity Examples include fish and grasshoppers.
