Population and Survivorship

A mouse with a short life span, produces more offspring than can survive, and gives little or no parental care is a

A generalist species is a species that generally has a wide range of things in their diets as well as a relatively large area of habitat.

• Generalists

• Specialist

These organisms have:

Short life span

Short gestation-pregnancy

Very little care for babies

Produce more offspring that can survive

• R-strategist

• K-strategist

• H-strategist

NGSS.MS-LS4-4

A pattern of survival over time in which there is low survivorship early in life with few individuals reaching adulthood.

• Type III survivorship

• Type II survivorship

• Type I survivorship

Population growth rate is figured out by

• Births-deaths

• Birth + deaths
