Carrying capacity: The maximum population of a given organism that a particular environment or habitat can sustain; implies continuing yield without environmental damage; often denoted as K. A one to one function is a function that has a single input for every output. Thus K-selected species are more prone to extinction than r-selected species because they mature later in life and have fewer offspring with longer gestation times.

Values for the measured property can be plotted on a graph as a function of time; see Figure 1 for an example. We analyze gene expression patterns of colorectal tumors from a large number of patients to test this assumption and propose an approach to identify potentially a continuum of subtypes that are present across independent studies and. The outcome is measured with a dichotomous variable (in which there are only two possible outcomes). When population abundance is low, the population grows exponentially.
