Near-shore distribution of Heaviside’s (Cephalorhynchus heavisidii) and dusky dolphins (Lagenorhynchus obscurus) at the southern limit of their range in South Africa

Photo-identification surveys over three years along 390 km of coastline north of Cape Town, revealed that Heaviside’s dolphin distribution was consistent between years and higher in areas more exposed to swells and with greater long-term availability of small hake Merluccius capensis (their principal prey). Dusky dolphin sighting rates varied considerably between years, but were generally higher in areas with lower hake availability and sandier shores (mostly straighter coastline). Large groups of 50–200 dusky dolphins were only seen in St Helena Bay, the site of a wind-driven upwelling zone. Heaviside’s dolphins were found in shallower, cooler water than dusky dolphins and were more likely to be seen during brighter phases of the moon (when nocturnal light conditions may influence the vertical migration patterns of prey) and in areas of high hake abundance. Near-shore fishing activity was higher in the northern half of the study area and clustered around harbours. Set netting occurred only at Yzerfontein and St Helena Bay, but due to changes in the industry is currently thought to be a low threat to the population. Interactions between Heaviside’s and dusky dolphins were usually neutral and sympatry appears to be mediated by differences in overall range and the type and size of prey species taken.     

赤潮研究中圆海链藻实时荧光定量PCR检测方法的建立

为建立快速、准确的鉴定和定量检测赤潮生物的方法,以圆海链藻为例，以其18S rDNA序列为寻找种特异性引物的靶区域，通过分析18S rDNA序列，设计出适合用于RFQ-PCR的引物与探针，并通过引物PCR验证确定其特异性，进而以圆海链藻荧光定量PCR的引物和探针（Primer Thalassiosira rotula和Taqman Thalassiosira rotula），建立了定量检测圆海链藻的实时荧光定量PCR检测方法（RFQ-PCR）。与传统的显微镜计数方法比较，两者所获结果无显著性差异，证明了本方法的可行性，从而为我国沿海水域赤潮问题的研究提供了良好的技术检测途径。     

Floral induction (FI) in longan (Dimocarpus longan, Lour.) trees. III: Effect of shading the trees on potassium chlorate induced FI and resulting hormonal changes in leaves and shoots

Previous experiments demonstrated that treatment of longan trees with potassium chlorate (KClO<sub>3sub>) induces “off season floral induction” (FI) even in the absence of the naturally required cool temperature [Manochai, P., Sruamsiri, P., Wiriya-alongkorn, W., Naphrom, D., Hegele, M., Bangerth, F., 2005. Year around off season flower induction in longan (Dimocarpus longan, Lour.) trees by KClO<sub>3sub> applications: potentials and problems. Sci. Hortic. 104, 379&ndash;390]. Potassium chlorate, however, cannot replace the presence of functional mature leaves and sufficient light intensity. Here we examined in more detail the effect of shade (about 10% of natural sunlight) on KClO<sub>3sub> affected hormone concentrations/transport of leaves and shoot apical buds (SAB) and their interactions with FI.

切花月季Rh-DREB1基因的克隆及其在乙烯和失水胁迫下的表达

以切花月季Rosa hybrida 'Samantha'为试材,通过简并引物和RACE方法从花瓣中获得了两个逆境诱导转录因子DREB家族基因全长.推定的氨基酸序列分析表明,这两个基因都具有DREB1转录因子的典型特征,因而分别命名为Rh-DREB1A和Rh-DREBIB,GenBank登录号分别为EU784069和EU784070.Rh-DREB1A和Rh-DREB1B分别包含一个编码222和231个氨基酸序列的开放阅读框.半定量RT-PCR分析结果表明,Rh-DREB1A和Rh-DREB1B在月季花瓣中能够被失水胁迫强烈诱导,但是不受乙烯诱导.由所得结果推测,这两个转录因子参与了失水胁迫诱导的信号转导途径.     

试论《三国志》裴松之注“凿空语怪”的文学意义

《三国志》裴松之注因为引用了几则具有志怪性质的材料，而被历来史家批评其“凿空语怪”、“坐长烦芜”。事实上，裴松之在引援这些注文时并非是不加选汰而盲目采用的。裴松之用审慎的态度和隐蔽的手段，把自己对历史人物及事实的评价暗蕴于注解之中。而且，其保存小说材料和用小说注史之功，是不可泯没的。《三国志》裴松之注将历史与小说相结合，则对当下的玄幻小说创作具有一定的启迪意义。
