Human activity has altered ecosystems in some places to a point where traditional restoration, ecosystem management and conservation interventions might not be feasible. This is especially true in densely populated urban areas if ongoing stressors are not ameliorated. As a result, different management options are needed for increasing native biodiversity and ecosystem function in novel urban ecosystems.
One strategy for increasing biodiversity in urban ecosystems is to employ invasion biology theory to augment the establishment and proliferation of desirable native species. Invasion hypotheses, including fluctuating resources, enemy release, novel weapons, invasional meltdown (facilitation) and propagule pressure, all provide insights into the mechanisms that increase the establishment and spread of populations. These hypotheses point to specific interventions that can be used in urban restoration and management.
Synthesis and applications. Viewing invasion mechanisms as a way to increase native biodiversity in novel urban ecosystems provides a useful reframing for assessing possible applications and management interventions for the most difficult-to-restore landscapes. We argue that conservation managers can use and test invasion hypotheses to inform biodiversity management practices in novel landscapes.

入侵理论作为增加城市生态系统本地生物多样性的管理工具

人类活动已经改变了某些地方的生态系统，以至于传统的恢复、生态系统管理和保护干预措施可能不可行。如果持续的压力源没有得到改善，那么在人口稠密的城市地区尤其如此。因此，需要不同的管理方案来增加新型城市生态系统中的本地生物多样性和生态系统功能。
增加城市生态系统生物多样性的一种策略是采用入侵生物学理论来增加理想的本地物种的建立和增殖。入侵假设，包括波动的资源、敌人释放、新型武器、入侵崩溃（促进）和繁殖压力，都提供了对增加种群建立和传播的机制的见解。这些假设指出了可用于城市恢复和管理的具体干预措施。
合成与应用。将入侵机制视为在新型城市生态系统中增加本地生物多样性的一种方式，为评估最难以恢复的景观的可能应用和管理干预提供了有用的重构。我们认为保护管理者可以使用和测试入侵假设来为新景观中的生物多样性管理实践提供信息。
