栖息地丧失和碎片化给全球濒危植物物种带来了很高的灭绝风险。对于许多濒危植物物种来说，随着残存的栖息地变得更小和更分散，估计小斑块的种群扩散率是至关重要的，以便有效地管理和保存它们，以备未来潜在的范围扩大。然而，种群扩散率很少在斑块水平上被量化，以便为保护战略和管理决策提供信息。为了缩小这一差距，我们量化了斑块特定的种子传播和当地种群动态，这是捷克共和国特有的极度濒危植物物种，是迫切需要保护的物种。Želivka和Hrnčíře，捷克。我们使用长期人口数据的人口预测矩阵进行人口分析，并使用解析的机理传播模型来模拟种子的传播。然后，我们利用当地种群动态和种子扩散的信息来估计种群扩散率，并比较种子扩散和种群增长率对种群扩散率的相对贡献。我们发现，虽然种子传播和种群增长速度都受到严格限制，但种群传播速度对最大传播距离的依赖比对种群增长速度的依赖更强。我们建议自然资源保护者大幅增加斯梅卡利木兰的传播距离。一般而言，努力提高种子传播能力可以极大地提高对极度濒危植物物种保护行动的效率和效果。为了给极度濒危的斯梅卡利水母的保护策略和管理决策提供信息，我们通过测定种子在每个残留斑块中的传播和当地种群动态来量化其特定斑块的种群传播率。我们发现，虽然种子传播和种群增长速度都受到严格限制，但种群传播速度对最大传播距离的依赖比对种群增长速度的依赖更强。我们建议环境保护者大幅增加斯梅卡利的传播距离，我们相信，努力提高种子传播能力可以极大地提高对极度濒危植物物种的保护行动的效率和效力。
Habitat loss and fragmentation impose high extinction risk upon endangered plant species globally. For many endangered plant species, as the remnant habitats become smaller and more fragmented, it is vital to estimate the population spread rate of small patches in order to effectively manage and preserve them for potential future range expansion. However, population spread rate has rarely been quantified at the patch level to inform conservation strategies and management decisions. To close this gap, we quantify the patch‐specific seed dispersal and local population dynamics of Minuartia smejkalii, which is a critically endangered plant species endemic in the Czech Republic and is of urgent conservation concern. Želivka and Hrnčíře, Czechia. We conducted demographic analyses using population projection matrices with long‐term demographic data and used an analytic mechanistic dispersal model to simulate seed dispersal. We then used information on local population dynamics and seed dispersal to estimate the population spread rate and compared the relative contributions of seed dispersal and population growth rate to the population spread rate. We found that although both seed dispersal and population growth rate in M. smejkalii were critically limited, the population spread rate depended more strongly on the maximal dispersal distance than on the population growth rate. We recommend conservationists to largely increase the dispersal distance of M. smejkalii. Generally, efforts made to increase seed dispersal ability could largely raise efficiency and effectiveness of conservation actions for critically endangered plant species. To inform conservation strategies and management decisions of the critically endangered Minuartia smejkalii, we quantify its patch‐specific population spread rate by determining seed dispersal and local population dynamics in each remnant patch. We found that although both seed dispersal and population growth rate in M. smejkalii were critically limited, the population spread rate depended more strongly on the maximal dispersal distance than on the population growth rate. We recommend conservationists to largely increase the dispersal distance of M. smejkalii, and we believe that efforts made to increase seed dispersal ability could largely raise efficiency and effectiveness of conservation actions for critically endangered plant species in general.
