生活在集合种群中的物种的生存依赖于相互连接的栖息地网络。如果栖息地网络经历快速的时间动态，物种保护就需要防止可能导致集合种群灭绝的栖息地不连续性。然而，用于维护保护区外时空动态栖息地网络的制度解决方案很少。为了探讨这个经常被忽视的问题，我们从保护机构管理这种濒危物种早期演替栖息地可用性的能力的角度研究了芬兰石南贝母 (Melitaea diamina) 保护的制度适应性。我们确定了四种能够对动态栖息地网络进行有效保护管理的制度安排：（1）承认栖息地动态，（2）监测和应对栖息地网络的变化，（3）针对不断变化的资源需求进行资源管理，以及（4）通过灵活的合作扩大活动规模。这些安排提供了应对栖息地可用性暂时变化所需的制度灵活性。
Species living in metapopulations depend on connected habitat networks for their survival. If habitat networks experience fast temporal dynamics, species conservation requires preventing habitat discontinuities that could lead to metapopulation extinctions. However, few institutional solutions exist for the maintenance of spatiotemporally dynamic habitat networks outside of protected areas. To explore this often neglected problem, we studied the institutional fit of false heath fritillary (Melitaea diamina) conservation in Finland from the perspective of conservation institutions’ ability to manage early successional habitat availability for this endangered species. We identified four institutional arrangements that enable effective conservation management of dynamic habitat networks: (1) acknowledgment of habitat dynamics, (2) monitoring of and responding to changes in the habitat network, (3) management of resources for fluctuating resource needs, and (4) scaling of activities through flexible collaborations. These arrangements provide the institutional flexibility needed for responding to temporal changes in habitat availability.
