物种多样性的模式提供了基本的洞察力的基本机制和过程,调节生物多样性。种-时间关系(STR)有可能成为这样的模式之一;在其更广泛研究的空间类似物,种-面积关系(SAR),这一直是生态模型和理论的发展的关键。我们试图确定的机制和过程,支持STR模式的时间营业额采样细菌群落内10个充满水的树洞在同一欧洲山毛榉树通过一年的过程。我们用这个自然模型系统来代表一个由大小不等的岛屿组成的群岛,这些岛屿有着共同的移民来源。我们观察到STR衍生的周转率和岛屿大小之间的反比关系。此外,营业额与岛屿的大小,而不是岛屿隔离的研究系统内的低频率的扩散限制和高的扩散。与可疑交易报告相比,对可疑交易报告的研究不足,因此,目前研究的结果应使人们重新对可疑交易报告的模式和过程产生兴趣。
Patterns of species diversity provide fundamental insights into the underlying mechanisms and processes that regulate biodiversity. The species–time relationship (STR) has the potential to be one such pattern; in a comparable manner to its more extensively studied spatial analogue, the species–area relationship (SAR), which has been pivotal in the development of ecological models and theories. We sought to determine the mechanisms and processes that underpin STR patterns of temporal turnover by sampling bacterial communities within ten water-filled tree-holes on the same European beech tree through the course of a year. We took this natural model system to represent an archipelago of islands of varying sizes and with shared common immigration sources. We observed an inverse relationship between STR-derived turnover rates and island size. Further, turnover was related to island size and not island isolation within the study system as indicated by a low frequency of dispersal limitation and high homogenizing dispersal. Compared to SARs, STRs are understudied, as such, the findings from the current study should provide a renewed interest in STR-based patterns and processes.
