摘要
Clonal populations are hierarchically organized: genetic individuals (genets) can consist of many physiological individuals (ramets).每個分株從其本地環境中獲取資源，但是可以透過分株之間的傳輸在克隆內重新組織資源模式。 Thus, an integrated clone is not directly subject to the pattern of resource availability in its habitat.局部短缺可以得到補償； hence, the clone can ‘buffer’ itself against spatio-temporal heterogeneity in the habitat. Weassum that sooat sooat sooal'at sooh. limiting resource was patchily distributed in space, and could fluctuate over time.棲息地類型在資源斑塊的密度、大小和持久性以及資源豐富的斑塊和資源貧乏的背景之間的對比方面有所不同。我們應用基於個體的、空間明確的族群動態模型來比較兩種植物策略在這些棲息地類型中的表現。 In the Integrator, ramets that were interconnected distributed the resource evenly. In the Splitter, no resource translocation occurred. First we observed population growth of the two strategies separately, then in competition.a formable, the because of the scarcity of resource patches. As the density of resource patches was increased, first only the Integrator could persist. Then, at intermediate densities of resource patches, the Splitter became viable, and and, peritor ). resource-patch densities, the Integrator occupied the area again.由於分裂者在單獨生長時可以在高密度的資源斑塊中生存，因此它的消失更多是由於自發滅絕，由於整合者的競爭排斥。 We predict, therefore, the dominance of integrated clones both in extremely unproductive and productive environments, but for different reasons. It is important to note that this trend was observable only at temp spatial. availability.不同品質的色塊之間的對比度較小、色塊尺寸較小或色塊的持久性較長，從而促進了分離器的主導地位。 Thus, buffering is advantageous in many but not all habitat types.
