Managing over-abundant nuisance species in anthropogenic environments typically depends on the removal of individuals, even though theoretical and empirical studies suggest that limiting environmental resources can be more effective. However, quantifying resources to be manipulated in order to achieve a desired reduction in target species can be difficult, which complicates cost estimation for a given management target. We present CEAMEC 1.0 (cost-effective animal management via environmental capacity), a ‘Shiny' application in the HTML user interface (available at <https://qt37t247.shinyapps.io/ceamec>) programmed in the R language, as a tool to provide managers with optimal management strategies based on cost estimates of manipulating different environmental resources. Based on user-defined targets and periods of management, CEAMEC calculates an optimal combination and quantity of different resources to be manipulated at the lowest cost to achieve a desired reduction level of a target population. CEAMEC provides stakeholders with a user-friendly decision support tool for integrated management plans targeting nuisance species in man-made environments.

CEAMEC 1.0：通过环境容量实现具有成本效益的动物管理的“闪亮”应用

在人为环境中管理过多的有害物种通常取决于个体的迁移，尽管理论和实证研究表明限制环境资源可能更有效。然而，量化要操纵的资源以实现目标物种的理想减少可能很困难，这会使给定管理目标的成本估算复杂化。我们展示了 CEAMEC 1.0（通过环境容量进行成本效益高的动物管理），这是一个以 R 语言编程的 HTML 用户界面中的“闪亮”应用程序（可在 <https://qt37t247.shinyapps.io/ceamec> 获得），作为为管理人员提供基于操纵不同环境资源的成本估算的最佳管理策略的工具。基于用户定义的目标和管理周期，CEAMEC 计算以最低成本操纵的不同资源的最佳组合和数量，以实现目标人口的预期减少水平。CEAMEC 为利益相关者提供了一个用户友好的决策支持工具，用于针对人造环境中有害物种的综合管理计划。
