异龙湖沉水植物分布格局与水环境因子相关性研究

异龙湖为中国云南九大高原湖泊之一,是处于草型向藻型湖泊转化节点上的典型高原湖泊,因历史原因,异龙湖东西湖区水环境条件差异较大,可较好的代表云南高原草型及藻型湖泊类型,因此研究异龙湖的沉水植物时空分布与水环境因子关系,对于我国高原湖泊的保护具有重要意义,且自1980年以来异龙湖沉水植物相关研究成果较少,因此,本研究在异龙湖开展为期一周年的水环境因子及沉水植物调查,对沉水植物分布格局及其与水环境因子之间相互关系进行了研究,以期为异龙湖的沉水植物研究留下珍贵的历史资料,并探索异龙湖沉水植物分布格局及其影响因子,为沉水植物恢复提供数据及技术支撑.结果表明:东西湖区沉水植物的群落结构具有显著差异,西湖区小茨藻(Najas minor All.)、狸藻(Utricularia vulgaris L)、轮叶黑藻(Hydrilla verticillata)等为优势种,东湖区篦齿眼子菜(Potamogeton pectinatus L)、狐尾藻(Myriophyllum verticilla-tum L)为优势种,且西湖区沉水植物的生物量及物种丰度显著高于东湖区.通过相关性分析看出水深、透明度、溶解氧是影响异龙湖沉水植物分布的主要环境因子,总氮、总磷、氨氮及pH是次要影响因子,异龙湖在现状条件下恢复沉水植物应针对不同湖区恢复采用不同的恢复策略,选择不同的沉水植物种类开展恢复工作.

两种水生昆虫头宽与基于图像分析的大小参数关系性分析

对于水生昆虫及其它生物而言,大小是一个重要的功能性状,但是头宽的测量特别耗时和受人为因素影响.随着计算机技术的发展,基于图像分析技术(一种快速测量大小的策略)可获得传统方式难以获得的大小参数,明确这些大小参数与头宽的关系,对推动这些参数的应用具有重要意义.选择两种个体大小差异较大的蜉蝣(梧州蜉和光滑细蜉)作为研究对象,对其头宽与基于数字图像获得的面积,周长,最小矩形的长和宽,最适合椭圆的长轴和短轴和粒径等个体大小参数的相关性进行研究.数字图像采用改进后的描述仪扫描获取;图像分析基于ImageJ软件完成;基于二元直线回归和多元直线回归分析各参数之间的相关性.各种层次的回归分析结果均表明:基于图像分析获得的两种蜉蝣所有个体大小参数均与头宽大小呈极其显著的正相关性,其中面积的相关性最高.并且面积与其它大小参数相关性也极其显著,对个体大小具有较好的代表性.研究结果为推动数字图像分析技术应用在水生昆虫及其它生物的生物学和生态学研究中提供了技术支持和理论依据.
