Status of the Black muntjac, Muntiacus crinifrons, in eastern China

A detailed survey was conducted to show the relative abundance and current known distribution of the Black muntjac population. New information on the distribution, abundance and status of Black muntjac shows it has a small population within a restricted geographical area and habitat range, which covers an area of approximately 76 , 500 km². The relative abundance of the Black muntjac at different locations was divided into three categories, depending on the percentage composition in hunting returns; these correlated with the amount of habitat destruction and hunting pressure. With the additional consideration of reproductive performance, the Black muntjac is doing well in some suitable areas. Data from historical records, and the new discovery of an isolated population in 1980 and 1981 indicated that habitat destruction and hunting greatly reduced the range and numbers of Black muntjac in the last hundred years. The paper also suggests that the current status of the Black muntjac should be given in the Red Data Book as a rare species.     

新集水电站对谷城汉江国家湿地公园生态影响分析

汉江是长江中游最大的支流之一，新集水电站位于汉江中游河段湖北省襄阳市内，坝址位于襄城区白马洞，谷城汉江国家湿地公园位于拟建新集水电站的库区，距离坝址约32.2 km。水电站建成后湿地公园水位上升影响面积为349.23 hm²（其中洲滩36.84 hm²，其他均为水域），生态保育区受水位上升影响面积为327.60 hm²，生态恢复区受水位上升影响面积为21.63 hm²。水电工程建设将显著改变原有的河流水文情势，直接或间接地影响鱼类等湿地生物的生存，产生一系列的生态效应，需对谷城汉江国家湿地公园生态影响进行评价。通过外业实地调查、资料收集和内业实验分析，现已基本查明了评价区域的生态环境现状，对项目建设对谷城汉江国家湿地公园的影响程度和方式进行了评价，并提出了减免生态影响的具体措施。

酶法拆分制备(R)-苯基缩水甘油醚及缓冲体系对产物光学纯度的影响

新筛选出一株能选择性水解外消旋苯基缩水甘油醚(GPE)的菌株Bacillus megateriumZJUZQ-001,研究了其动力学拆分苯基缩水甘油醚条件,包括时间、温度、缓冲液类型和离子强度的影响。相比其他体系,硼酸缓冲液(100 mmol/L,pH 8.2)e.e._s值可以从91.2%提高到99.5%,E值从25.0提高到46.8,底物浓度从60 mmol/L增加到90 mmol/L。
