在美国，蚊媒疾病因其在人类中看似不稳定的时间和空间爆发模式而臭名昭著。识别细尺度现象和宏观尺度爆发模式之间的联系可以提高对这些复杂的社会生态系统的理解。ObjectivesUsing West Nile virus（WNV）as a model system，we examine whether fine scale wetland characteristics-wetland size，connectivity，和洪水制度，有一个重要的影响，在美国东北部和中西部的大规模人类疾病爆发。的方法，得出新的宏观尺度湿地指标的基础上，精细尺度湿地的特点，并使用县级年度人类西尼罗河病毒发病率数据超过11年，以评估之间的联系，精细和宏观尺度结果在西尼罗病毒媒介--跗库蚊流行区，平均湿地面积较小的美国县的人类西尼罗河病毒发病率比平均湿地面积较大的县高出100%以上。在Cx占主导地位的地区。pipiensandCx. restuansvectors，低比例面积的连接湿地与至少50%以上的人类西尼罗河病毒发病率比高比例面积的连接湿地。最后，CX。在经历干旱条件的半永久性湿地面积比例高的以跗跖为主的县，其年WNV发病率比半永久性湿地面积比例低的受干旱影响的县高出300%以上。结论我们的研究结果表明，在个别湿地尺度上发生的现象可能会聚集起来影响宏观尺度的人类西尼罗河病毒爆发模式，并可能通过其他因素的相互作用来介导例如病媒物种特有的特征和气候。
ContextMosquito-borne diseases in the United States are notorious for their seemingly erratic temporal and spatial outbreak patterns in humans. Identifying linkages between fine-scale phenomenon and macroscale outbreak patterns can improve the understanding of these complex socio–ecological systems.ObjectivesUsing West Nile virus (WNV) as a model system, we examine whether fine-scale wetland characteristics—wetland size, connectivity, and inundation regime—have an important effect on macroscale human disease outbreak in the northeastern and midwestern United States.MethodsWe take a spatially explicit GIS-based approach, derive new macroscale wetland metrics based on fine-scale wetland characteristics, and use county-level annual human WNV incidence data over 11 years to evaluate linkages between the fine and macroscales (1.6 million km2).ResultsIn regions dominated by theCulex tarsalisWNV vector, U.S. counties with a small average wetland size had more than 100 % higher human WNV incidence than counties with a large average wetland size. In regions dominated by theCx. pipiensandCx. restuansvectors, a low proportional area of connected wetland was associated with at least 50 % higher human WNV incidence than a high proportional area of connected wetland. Finally,Cx. tarsalis-dominated counties with a high proportional area of semi-permanent wetland that were experiencing drought conditions had over 300 % higher annual WNV incidence than drought-affected counties with a low proportional area of semi-permanent wetland.ConclusionsOur results suggest that phenomena occurring at the individual wetland scale may aggregate to influence macroscale human WNV outbreak patterns and may be mediated by the interplay of other factors such as vector species-specific traits and climate.
