In humans and animals, there is a regulatory system that governs the phase relationship of an organism's internal circadian clock to a regular periodicity in the external environment (usually governed by the solar day). In most organisms, a stable phase relationship is desired, though in some cases the desired phase will vary by season, especially among mammals with seasonal … WebbThe physiological response curve (Figure 1) describes potential organism distribution limits along an environmental factor or resource gradient in the absence of competition …
