Fitness increases with this quantity in the Allee effect.
Plots of this quantity against time may show a lag phase and a log phase. Fitness increases with this quantity in the Allee effect. Quorum sensing is activated when this quantity is large. This quantity suddenly increases during irruption, which can lead to an overshoot, during which it suddenly drops. The time derivative of this quantity is proportional to this (*) quantity, times K minus this quantity, in the logistic equation. This quantity is estimated by tagging, releasing, and then recapturing. It increases exponentially until it levels off at the carrying capacity. For 10 points, name this quantity, the number of organisms in a given area.
