      R = reproductive rate.  K = carrying capacity.  Species that are great at reproducing and making babies that can enter an open space and grow there are r selected.  Species that tend to grow more slowly but stay in place for a long time til the habitat hits its carrying capacity are called k selected.  What are some traits that you would expect to see in r versus k selected species

k strategy organisms are long lived, generally reproduce more slowly, don't reproduce til they're older. Elephants, turtles, oak trees, etc are all k-strategists. 

R-strategists are short lived, reproduce a lot more offspring and can reproduce when they're young. Insects and dandelions are great examples. 

R and k simply denote whether their population sizes can increase exponentiall (r-selected) or whether their populations sizes sort of fluctuate around a given number (known as the carrying capacity).
