狮子鱼到西北大西洋和加勒比海的快速入侵无疑会影响本地珊瑚礁鱼类通过过程，如营养破坏和生态位接管，但鲜为人知的是这种入侵的动态。我们构建了一个基于阶段的矩阵种群模型，其中矩阵元素由较低级别的参数组成。狮子鱼的生命率估计从现有的文献和新的领域和实验室研究。较低级别的参数的敏感性分析表明，人口增长率是最受幼虫死亡率的影响，矩阵的弹性分析表明成人和少年的生存元素的强烈影响。根据这个模型，大约27%的入侵成年狮子鱼种群将不得不每月被移除，以减少丰度。分层建模表明，该点估计值福尔斯落在一个很宽的不确定性区间内，这可能是由于生活史参数的不精确估计造成的。该模式表明，针对青少年和成年人的持续清除工作可以大大提高效率。
The rapid invasion of lionfish into the Western North Atlantic and Caribbean will undoubtedly affect native reef fishes via processes such as trophic disruption and niche takeover, yet little is known about the dynamics of this invasion. We constructed a stage-based, matrix population model in which matrix elements were comprised of lower-level parameters. Lionfish vital rates were estimated from existing literature and from new field and laboratory studies. Sensitivity analysis of lower-level parameters revealed that population growth rate is most influenced by larval mortality; elasticity analysis of the matrix indicated strong influence of the adult and juvenile survival elements. Based on this model, approximately 27% of an invading adult lionfish population would have to be removed monthly for abundance to decrease. Hierarchical modeling indicated that this point estimate falls within a broad uncertainty interval which could result from imprecise estimates of life-history parameters. The model demonstrated that sustained removal efforts could be substantially more effective by targeting juveniles as well as adults.
