Molecular phylogenetic analysis of attached Ulvaceae species and free-floating Enteromorpha from Qingdao coasts in 2007 总被引:2,自引:1,他引:2
Based on the sequence data of the nuclear ribosomal DNA internal transcribed spacer(ITS) 1,5.8 S,and ITS 2,the molecular phylogeny was analyzed on Ulvaceae species collected from Qingdao coasts in summer of 2007,including 15 attached Ulva and Enteromorpha samples from 10 locations and 10 free-floating Enteromorpha samples from seven locations.The result supported the monophyly of all free-floating Enteromorpha samples,implying the unialgal composition of the free-floating Enteromorpha,and the attached Ulvaceae species from Qingdao coasts were grouped into other five clades,suggesting that they were not the biogeographic origin of the free-floating Enteromorpha in that season. 相似文献

Ulvacean green seaweeds are common worldwide; they formed massive green tides in the Yellow Sea in recent years, which caused
marine ecological problems as well as a social issue. We investigated two major genera of the Ulvaceae, Ulva and Enteromorpha, and collected the plastid rbcL and nuclear ITS sequences of specimens of the genera in two sides of the Yellow Sea and analyzed them. Phylogenetic trees
of rbcL data show the occurrence of five species of Enteromorpha (E. compressa, E. flexuosa, E. intestinalis, E. linza and E. prolifera) and three species of Ulva (U. pertusa, U. rigida and U. ohnoi). However, we found U. ohnoi, which is known as a subtropical to tropical species, at two sites on Jeju Island, Korea. Four ribotypes in partial sequences
of 5.8S rDNA and ITS2 from E. compressa were also found. Ribotype network analysis revealed that the common ribotype, occurring in China, Korea and Europe, is connected
with ribotypes from Europe and China/Japan. Although samples of the same species were collected from both sides of the Yellow
Sea, intraspecific genetic polymorphism of each species was low among samples collected worldwide. 相似文献

低阶煤低温干馏生成的煤焦油是重要有机化工原料,焦油加工精炼已作为近代煤化工的一个重要分支.为了建立煤焦油产率预测技术方法,服务于煤焦油地质储量评价,本文在文献调研基础上,遵循“地质约束测井、岩心刻度测井”原则,开展研究区煤焦油产率敏感因素分析,厘定与煤焦油产率相关地质参数,利用统计分析方法确定与煤焦油产率敏感的测井信息;利用多元回归分析方法和神经网络技术首次开展了煤焦油产率测井预测方法探索.研究表明,低阶煤的焦油产率普遍高于中高阶煤,对煤焦油产率敏感的地质因素主要有煤化程度(镜质体反射率)、温度和压力、煤质灰分与固定碳含量;对煤焦油产率敏感的测井信息主要包括补偿密度、自然伽马、电阻率等;分区开展多元回归建模可实现利用密度、自然伽马和电阻率测井响应对煤焦油产率预测;将神经网络技术引入煤焦油产率分区预测可行.研究成果对做好煤焦油地质储量评价具有重要的技术支撑作用. 相似文献

矿区地质条件复杂,高效、准确的陷落柱识别至关重要。在传统方法中,解释陷落柱最常采用的是人机交互解释方法,但随着勘探规模的扩大、生成数据的不断积累,传统的人工解释陷落柱已满足不了实际生产需要。为了提高陷落柱的识别精度,提出了CINet(Collapse Column Identification Network)网络模型,把自动识别陷落柱的方法看作二分类问题,在深度学习算法残差网络的基础上对残差模块进行改进,构建出新的网络模型CINet,引入平衡交叉熵损失,解决数据中陷落柱与非陷落柱比例高度不平衡问题,使模型朝着正确的方向收敛。通过模型的预测结果与实际数据比对表明,相比于传统的机器学习和残差网络模型,CINet网络模型可以从原始数据中学习到更加详细的特征信息,提高陷落柱的识别精度,
