依据有关文献资料,讨论了掌突蟾属的学名有效性问题和亚属分类问题,结果表明掌突蟾属的有效学名为ParamegophrysLiu,1964;该属可分为2个亚属,即掌突蟾亚属Paramegophrys(Paramegophrys)Liu,1964和拟掌突蟾亚属Paramegophrys(Leptolalax)Dubois,1980;目前,它们分别包含11种.     

Millennial temperature reconstruction based on tree-ring widths of Qilian juniper from Wulan, Qinghai Province, China

The climate of the past 1000 years is an important context for evaluating the recent climate warming. However, there are few 1000-year-long climate reconstructions with annual resolution in the Qinghal-Tibet Plateau. In this paper, a dendroclimatic analysis was conducted for the radial growth of Qilian juniper from the upper forest limit in Wulan, Qinghai Province. The results of correlation analysis between the tree-ring widths and the climate variables indicate that the growth of junipers at the upper forest limit is mainly limited by low temperatures of September, November and February of the pregrowth season, and July of the current growth season. There is no significant correlation between the tree-ring widths and precipitation. A mean temperature from the previous year＇s September to the current year＇s April was reconstructed for the Wulan area since A.D. 1000. The reconstruction can explain 40.8% of the instrumental variance in the calibration period （1856-2002）. The reconstruction shows that the 20th century is the warmest 100 years, and the 1990s is the warmest decade during the past 1000 years, while the coldest 100 years and decade occur at 1600-1699 and 1642-1651, respectively. The variations are verified well by the temperature reconstruction of the middle Qilian Mountain （QL） and the total organic carbon （TOC） in the Qinghai Lake sediments. The comparison of our reconstruction with the annual temperature reconstruction of extra-tropical Northern Hemisphere suggests that the climate of Wulan during the Medieval Warm Period is of obvious regional specialty, but there was a good response to the climate of hemispheric scales during the recent 400 years.

用mtDNA COII基因序列确定我国北部湾红树植物白骨壤虫灾虫源

从我国近年来遭受特大虫灾的北部湾沿海红树植物白骨壤上采集害虫标本,测定其线粒体DNA细胞色素c氧化酶亚基II(COII)基因序列,并与采自深圳湾白骨壤上的害虫标本以及相关类群的COII 基因序列进行同源性比较,结果表明来自北部湾与深圳湾白骨壤的虫源均为瘤斑螟属Ptyomaxia, 而不是细斑螟属Oligochroa.分子系统发育分析为纠正以前普遍认为广州小斑螟引发我国红树林特大虫灾的观点提供了新的证据.
