Network analysis is used to address diverse ecological, social, economic, and epidemiological questions, but few efforts have been made to combine these field-specific analyses into interdisciplinary approaches that effectively address how complex systems are interdependent and connected to one another. Identifying and understanding these cross-boundary connections improves natural resource management and promotes proactive, rather than reactive, decisions. This research had two main objectives; first, adapt the framework and approach of infectious disease network modeling so that it may be applied to the socio-ecological problem of spreading aquatic invasive species, and second, use this new coupled model to simulate the spread of the invasive Chinese mystery snail (Bellamya chinensis) in a reservoir network in Southeastern Nebraska, USA. The coupled model integrates an existing social network model of how anglers move on the landscape with new reservoir-specific ecological network models. This approach allowed us to identify 1) how angler movement among reservoirs aids in the spread of B. chinensis, 2) how B. chinensis alters energy flows within individual-reservoir food webs, and 3) a new method for assessing the spread of any number of non-native or invasive species within complex, social-ecological systems.
网络分析用于解决各种生态、社会、经济和流行病学问题，但很少有人致力于将这些特定领域的分析整合到跨学科方法中，以有效解决复杂系统如何相互依存和相互关联的问题。识别和理解这些跨界联系有助于改善自然资源管理，并促进做出主动而非被动的决策。本研究有两个主要目标：第一，调整传染病网络建模的框架和方法，使其可应用于水生入侵物种传播的社会生态问题；第二，使用这个新的耦合模型模拟入侵性中华圆田螺（Bellamya chinensis）在美国内布拉斯加州东南部一个水库网络中的传播。该耦合模型将现有的关于垂钓者在景观中移动方式的社会网络模型与新的特定水库生态网络模型整合在一起。这种方法使我们能够确定：1）垂钓者在水库之间的移动如何促进中华圆田螺的传播；2）中华圆田螺如何改变单个水库食物网内的能量流动；3）一种评估复杂社会生态系统中任意数量的非本地或入侵物种传播的新方法。
