R selection, K selection and survivorship curves

The R selection is a type of reproduction strategy are those that place an emphasis on a high growth rate, and, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood. The K-selected species possess relatively stable populations and tend to produce relatively low numbers of offspring; however, individual offspring tend to be quite large in comparison with r-selected species.In general house pets tend to be K selected while house pests tend to be R selected. This is not universally true because there are certain cases when pets can be R selected and when pests can be K selected. For example hamsters rabbits and gerbils would all be classified as R selected species. They are under that classification because they have tendencies to have high growth rates and
a relativity low probability to survive adulthood. It is a little harder to find pests that are K selected species. But in my area deer are considered by many to be pests. Deer fall under the classification of K selected species because they have a relatively stable population and produce a lower amount of off spring. In recent history humans have had a mass increase of life span and a mass decrease in birthing rates. Humans have transferred from being R section species to K selection species and ultimately becoming a dominate species on this planet.
