利用两种活体荧光技术分析北极微藻对光照变化的响应

采用调制叶绿素荧光技术（脉冲-振幅-调制：Pulse-Amplitude-Modulation,简称为PAM技术）和荧光光谱两种技术研究不同光照下的两种北极微藻（北极异帽藻（Heterocapsa arctica）和红胞藻（Rhodomonas sp.）的荧光特性,发现（1）两种藻在三个不同光照水平下（5 000 lux、15 000 lux、25 000 lux）光合生理变化特征相似：随着光照强度增加,光量子产量越低,光合效率越低;在15 000 lux和25 000 lux两个较强光照条件下,最大光合电子传递速率（rETRmax）没有提高,且捕光能力下降;25 000 lux光照强度下,均处于胁迫状态,但对强光的耐受能力增强;（2）两种藻在15 000 lux条件下Chl a荧光强度最高,25 000 lux条件下的Chl a荧光强度都显著降低,受到不同程度的光损伤;类胡萝卜素和多甲藻素是维持北极异帽藻15 000 lux下种群生存的有效色素;藻胆素和Chl c则分别为维持红胞藻5 000 lux和15 000 lux条件下的种群的生存起了积极作用。     

菲尔德斯半岛潮间带生物生态学的研究

198 7年 1 1月 - 1 989年 3月我们连续跨年度在菲尔德斯半岛潮间带 -浅海区域系统地进行了生态学考察 ,获得了宝贵的第一手资料。在生物组成及其生态分布的研究中 ,我们分别选择了长城湾、马尔什基地、生物湾、阿德雷岛、半三角及无名岛进行定期观察、取样 ,它们分别代表了岩石、石砾、泥沙滩、暴浪及隐蔽性内湾等各类生态类型。数量分法的引进是生态学研究中的一大进步 ,使之成为一门精密学科。本文在数量方法的使用中 ,引入了生物量、频度与覆盖度等手段 ,丰富了数量方法的内容。菲尔德斯半岛就象整个南极区域一样 ,其食物网是较为简单的。以黑背海鸥为代表的海鸟和南极鳕 ,南极银鱼等占据了营养级的顶层 ,肉食性的螺类和草食性的帽贝位于中间层次 ,大型底栖与微观浮游藻类构成营养级底层。菲尔德斯半岛习见的微生物种类有黄杆菌、纤维粘细菌、莫拉氏菌等 ,它们是腐食食物网的重要组成部分。菲尔德斯半岛潮间带生物的季节变化一般表现为三种形式。其一是生物群落结构的变化 ;其二是生物分布空间的变化 ;其三是严酷的冬季几乎所有的潮间带生物种类几近绝迹。由于生物季节的短暂与分布空间的狭小 ,生物的种间竞争是相当激烈的。岩相底质的同质性与异质性以及软相底质中的表附与底内生物等不同生态类型 ,     

Siliceous microfossil distribution in the surficial sediments of Lake Baikal

Examination of surficial sediments at 16 stations shows minor, but consistent differences in the numbers and kinds of siliceous microfossils deposited in different regions of Lake Baikal. There is a general north-south decreasing trend in total microfossil abundance on a weight basis. Endemic plankton diatom species are the most abundant component of assemblages at all stations. Chrysophyte cysts are present at all stations, but most forms are more abundant at northern stations. Non-endemic plankton diatom species are most abundant at southern stations. Small numbers of benthic diatoms and sponge spicules are found in all samples. Although low numbers are present in offshore sediments, the benthic diatom flora is very diverse. Principal components analysis confirms primary north-south abundance trends and suggests further differentiation by station location and depth.     

塘坂水库春季养鱼控藻围隔试验研究

塘坂水库作为福州市区的第二水源地,每年4—10月份频繁暴发以微囊藻为优势种的蓝藻水华．为了控制藻类的大量生长,进一步提高库区水质,本研究采用非经典生物操纵理论,进行现场围隔试验．2012年4-5月,在塘坂水库设置围隔放养不同种类的鱼探索其控藻的效果．结果显示：放养鱼类40天后,放鱼组围隔内浮游植物群落结构发生改变,蓝藻所占比例下降,硅藻和绿藻逐渐增加;同时,放养鱼类促使水体叶绿素-a值升高,藻类小型化．     

The use of sedimentary algal pigments to infer historic algal communities in Lake Apopka,Florida

The primary producer community of Lake Apopka, a large (125 km²), shallow (mean depth, 1.7 m), polymictic Florida lake, shifted from macrophyte dominance to phytoplankton dominance in the 1940s. Today, frequent wind resuspension of highly organic, unconsolidated sediments supports a meroplanktonic community that is predominantly diatoms, but during calm periods the algal community is dominated by planktonic cyanobacteria. Sedimentary algal pigments (chlorophyll derivatives and carotenoids) and chemical proxies for nutrient enrichment (polyphosphate, total phosphorus and biogenic silica) in three sediment cores were used to investigate historic changes in primary producers. Sediments were separated into three stratigraphic zones using multivariate statistical techniques. Stratigraphic zonation was established in each core although sediment deposition at one site was insufficient to adequately resolve temporal changes. These results show the importance of selecting suitable sites for paleolimnological studies. The oldest zone represents macrophyte-derived sediments, and the two overlying zones represent phytoplankton-derived sediments deposited since the 1940s. Algal pigments in the most recent sediment zone show little degradation, which might be due to the presence of viable meroplankton in the sediment. After the initial primary producer shift from macrophytes to phytoplankton, the lake experienced a short period of cyanobacterial dominance followed by a period of benthic diatom abundance before being replaced by the present algal community consisting of cyanobacteria and meroplanktonic diatoms. Chlorophyll derivatives and carotenoids were highly correlated with total phosphorus. Historic trends inferred from the data include algal and cyanobacterial productivity that increased with increased phosphorus loading. The study demonstrates that valid paleolimnological proxies for historic eutrophication are available in loosely consolidated sediments of shallow, subtropical lakes.
