Wetlands and drought linked to Cs. melanura abundance and infection with Eastern Equine encephalitis virus in Connecticut, USA, 2001-2014

This dataset contains information on the monthly mean number of Culiseta melanura individuals captured per night and monthly presence/absence of Eastern equine encephalitis virus (EEEV) in Cs. melanura pools at 97 unique mosquito surveillance sites in Connecticut. Data were collected between June and October from 2001 to 2014. These data also describe the characteristics of palustrine wetlands around each surveillance site within circular buffers with radii of 50m, 100m, 200m, 500m, 750m, 1000m, 1500m, 2000m, 3000m, 4000m, and 5000m. Wetland characteristics are derived from the US Fish and Wildlife Service National Wetlands Inventory and include the proportional area of several wetland vegetation types, the average forested wetland size, the mean number of forested wetland connections to streams, and the proportional and relative area of forested semi-permanent wetland. We also include the mean percentage of impervious surfaces within each of the above circular buffers, which is derived from the 2006 National Land Cover Database Percent Developed Impervious layer. Finally, the palmer hydrological drought index (PHDI) during and 12 months prior to mosquito surveillance are included.

本数据集涵盖美国康涅狄格州97个独立蚊虫监测站点的相关监测数据：一是2001年至2014年6月至10月期间，每夜捕获的黑脉毛蚊（Culiseta melanura）的月均个体数量；二是各站点黑脉毛蚊（Cs. melanura）混合样本中东部马脑炎病毒（Eastern equine encephalitis virus, EEEV）的月检出存在/缺失情况。本数据集同时包含各监测站点周边不同半径圆形缓冲区（半径分别为50m、100m、200m、500m、750m、1000m、1500m、2000m、3000m、4000m及5000m）内的淡水沼泽湿地特征信息，湿地特征数据源自美国鱼类及野生动物管理局（US Fish and Wildlife Service）的国家湿地清单（National Wetlands Inventory），具体涵盖多种湿地植被类型的面积占比、森林湿地平均面积、森林湿地与溪流的平均连通数量，以及森林半永久湿地的面积占比与相对面积。此外，本数据集还纳入了上述各圆形缓冲区内的不透水面平均占比数据，该数据源自2006年国家土地覆盖数据库（National Land Cover Database）不透水面开发百分比图层。最后，本数据集还包含蚊虫监测期间及此前12个月的帕尔默水文干旱指数（Palmer hydrological drought index, PHDI）。
