چکیده انگلیسی
All biological events, phenomena and processes on Earth have a time of start and a time of end. An accurate and precise definition and determination of the window of a biological event is of both theoretical and practical value. In this paper, I define the window of a biological event and derive models for its calculation. Specifically, the window of a biological event is defined through the progression of its biological time. Let a biological event start at time tL and end at time tR. As time Ï varies from tL to tR, its biological time varies from a(tL) at time tL to a(tR) at time tR. The equation of biological windows is defined as a(tR)âa(tL)=â«ada=â«tLtR(da(Ï)/dÏ)dÏ, with a window width of tR â tL, a window height of da(Ï)/dÏ at time Ï â [tL, tR], and a window area of a(tR) â a(tL). The standard equation of biological windows is defined as 1=â«tLtR(1/(a(tR)âa(tL)))(da(Ï)/dÏ)dÏ, with a window width of tR â tL, a window height of (da(Ï)/dÏ)/[a(tR) â a(tL)] at time Ï â [tL, tR], and a window area of unity. A stochastic model is also given. Both types of model are related to multiple ecological factors through a first-order nonlinear partial differential equation. I use the special cases of both types of model to analyze data collected in the laboratory to demonstrate their utility.
