Oryza rufipogon is the wild relative of cultivated rice. In its native SE Asia, annual and perennial populations can be found. Annual populations typically grow in aquatic habitats that dry out seasonally, while perennials typically grow in more permanent aquatic habitats. In their respective habitats, annuals produce narrower leaves than perennials. An experiment was conducted where annual and perennial seeds were grown together in a permanent aquatic habitat and demographic data on survival and fecundity were collected. The data are below: Annual seeds 1st year survival 0.01 0.01 seeds per year 180 90 Adult survival rate 0.0 Perennial seeds 0.4 Using what you know about demographic life history theory, do these data support the observed life history strategies in nature? Why or why not?

R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.
