temporal change

This file contains the change in susceptibility and proportion sexual females at each site through time. The change is calculated as the value in 2015 minus the value in 2013. Data columns are as follows: (1) site (n=13); (2) sex: change in the proportion of sexual females; (3) susceptibility: change in overall susceptibility; (4) sexual_susceptibility: change in susceptibility of sexual females.本文件包含各站点随时间变化的易感性（susceptibility）以及有性雌性个体占比数据。该变化量以2015年数值减去2013年数值计算得到。数据列说明如下：(1) site（站点，共13个）；(2) sex：有性雌性个体占比的变化量；(3) susceptibility（整体易感性）：整体易感性的变化量；(4) sexual_susceptibility（有性雌性易感性）：有性雌性个体易感性的变化量。
