Reconstruction of Polytrichum juniperinum population dynamics in a mire of China

Abstract

Abstract: By using ‘history reconstruction method',this paper studied the dynamics of two Polytrichum juniperinum populations with and without sporophytes.The population with sporophyte production experienced a dynamic process from increase to stabilization,while that without sporophyte production experienced a process from increase to decrease.Before 2003,both the increase rate and the birth rate of two populations decreased continuously,with the death rate showing the tendency from decrease to a continuous increase.The advantages of 'history reconstruction method' in studying population dynamics were proved and discussed.

Key words: Polytrichum juniperinum, History reconstruction, Population dynamics
