SummaryDirect human activity and global climatic changes are threatening the existence of many vegetated habitats. Seedling establishment, one of the riskiest plant life stages, must be successful for such habitats to persist. The establishment of seedlings is known to be enhanced by nurse effects, but most studies to date have looked at the nursing effects of plants while sidelining inanimate objects. Nevertheless, nurse objects can support seedling establishment via diverse mechanisms such as moderating abiotic stresses like extreme temperatures and drought, reducing negative biological interactions such as herbivory while enhancing positive processes like seed dispersal, and providing protection from physical disturbances such as trampling and fire. The robust nature of nurse objects highlights their potential in habitat restoration. The addition of nurse objects allows a simple, single‐effort rehabilitation strategy that can later draw on natural seed dispersal and establishment. By achieving a better understanding of the processes in which nurse objects are involved we should be able to better predict vegetation dynamics and manipulate them to minimize adverse processes and support regeneration in natural habitats.

系统评价了护士对象作为育苗的安全场所及其对恢复的意义


摘要直接的人类活动和全球气候变化正在威胁许多植被栖息地的存在。幼苗建立是植物生命中最危险的阶段之一，必须成功才能使这种栖息地持续存在。众所周知，护士效应会促进幼苗的建立，但迄今为止的大多数研究都着眼于植物的护理作用，而忽略了无生命的物体。尽管如此，护理对象可以通过多种机制支持幼苗的建立，例如调节极端温度和干旱等非生物胁迫，减少食草等负面生物相互作用，同时增强种子传播等积极过程，并提供保护免受踩踏和火灾等物理干扰。护士物体的坚固性凸显了它们在栖息地恢复方面的潜力。添加护士对象允许一种简单的、单工一时的康复策略，以后可以利用自然种子的传播和建立。通过更好地了解护士物体所涉及的过程，我们应该能够更好地预测植被动态并操纵它们以最大限度地减少不利过程并支持自然栖息地的再生。
