Definitions for "K-selection"
The concept that in certain (K-selected) populations, life history is centered around producing relatively few offspring that have a good chance of survival.
Natural selection that occurs in populations near the carrying capacity (K) of the environment. Usually causes a species that produces few young with substantial resource investment by the parents; parents care for the young until they mature. (K-selected, adj.)
K-selected species reproduce slowly. They produce altricial offspring requiring a long time to maftire. R-selected species reproduce quickly and have many offspring. They produce many precocial offspring that quickly mature. K-selection and r-selection are relative terms. Prosimians are more r-selected than apes but ants are much more r-selected than prosimians.
