Discussion
The simulated results under ecologically neutral dynamics demonstrated
that the upper limits exist in temporal distance-decay patterns; thus,
the temporal distance-decay curves saturate before reaching a completely
dissimilar state. In addition, the form of the curve strongly depends on
four parameters of the neutral model: fundamental biodiversity number,
local community size, mortality rate, and immigration rate. These
results emphasise the importance of considering the basic information of
the species pool and local communities as four parameters in the present
study when temporal beta-diversity studies are expanded to
macroecological contexts. No studies have seriously considered the
differences between space and time; therefore, this study is the first
to explore biodiversity changes from both basic and applied
perspectives.
