脉冲储备范式（PRP）是旱地生态学的核心，尽管微生物特征在其开始时并未被明确考虑。我们询问PRP是否可以重新定义，以涵盖大型和小型生物。我们综合回顾了干旱区微生物生态学的最新进展，并结合数学上明确的理论模型。通过建立保护区来保护PRPs适应的核心，该模型考虑了不同的生物策略来管理这些保护区。根据生物的储备策略，提出了从敏捷反应者（NIRs）到迟钝反应者（tor）的梯度。它预测了有机体适应性如何依赖于脉冲机制和储备策略，部分解释了有机体多样化和分布。在考虑了结垢现象并重新定义了干燥的微尺度含义后，证据表明PRP适用于微生物。这一修改后的PRP代表了一个适用于各种生命形式的包容性理论框架，尽管仍需要直接测试。
The pulse–reserve paradigm (PRP) is central in dryland ecology, although microorganismal traits were not explicitly considered in its inception. We asked if the PRP could be reframed to encompass organisms both large and small. We used a synthetic review of recent advances in arid land microbial ecology combined with a mathematically explicit theoretical model. Preserving the PRPs core of adaptations by reserve building, the model considers differential organismal strategies to manage these reserves. It proposes a gradient of organisms according to their reserve strategies, from nimble responders (NIRs) to torpid responders (TORs). It predicts how organismal fitness depends on pulse regimes and reserve strategies, partially explaining organismal diversification and distributions. After accounting for scaling phenomena and redefining the microscale meaning of aridity, the evidence shows that the PRP is applicable to microbes. This modified PRP represents an inclusive theoretical framework working across life-forms, although direct testing is still needed.
