Zhejiang Daxue xuebao. Lixue ban, 2014 以杭州市7条主要河道21个监测断面1循环年的水质监测数据为依据，运用污染指数法和模糊评价法对市区主要河道水质进行综合评价，同时探讨2种水质评价方法的评价效果.结果表明：①杭州市区主要河道均存在不同程度的污染，主要污染物是TN、-N和TP，即氮磷营养盐，而有机污染相对较小；②污染指数法评价结果与实际水体的标准差距较小，与真实情况吻合较好；③当水质为劣V类时，模糊评价结论偏保守，而当某项指标严重超标时则易使评价结果偏重；④污染指数法更适合杭州市区河道水环境的评价.

Wildlife Letters, EarlyView.We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that
