The prevalence and abundance of the acanthocephalan exhibited very similar and significantly seasonal change patterns in O. uncirostris and H. bleekeri bleekeri. The infection levels were higher in autumn and winter, but lower in spring and summer. However, the infection levels in Z. platypus kept stable all the year round. There were significant differences among the overall abundance of the acanthocephalan in the three host populations. Nevertheless, the frequency distribution of the parasite in the three kinds of fish was over-dispersed in most seasons and in total as measured by the variance to mean ratio. The variance to mean ratio was not found related to the infection levels.

在感染率和感染丰度方面，寄生于马口鱼和油的木村小棘吻虫呈现出显著的季节变化：秋冬季节感染率和感染丰度都比较高，而春夏季节则比较低；与此不同的是，寄生于宽鳍鱲中的木村小棘吻虫则全年都维持着较稳定的感染水平；木村小棘吻虫种群在三种宿主体内的总体感染丰度差异显著，但都呈聚集分布，三者的方均比与感染率和感染丰度之间无显著相关关系。

In the different zoning of xenoliths, molybdenum and tungsten contents is lower and homogeneous,and be lower than the world\'s average abundance; tungsten compared to molybdenum,the content more homogeneous in xenoliths, compared to mantle\'s average abundance more less. This explains the geochemistry incompatible character homophyly and diversity of molybdenum and tungsten determined their trend enrichment in crust in the course of the mantle evolution and magmatism, among molybdenum more trend enrichment in lower crust but tungsten in middle-upper crust.

包体不同带中，钼、钨的含量较低且较为均一，并低于世界均匀丰度；钨和钼相比，其在包体中的含量更为均一，相对于地幔均匀丰度更小，说明钨、钼的地球化学不相容性的类似性和差异性决定了它们在地幔演化和岩浆过程中倾向富集于地壳中，其中钼更倾向富集于下地壳，钨则更倾向富集于中上地壳。

The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

结果表明：茶园共有杂草16科31属31种，春季（4月）以生长速度较慢、生物量小、株高在30 cm以下的杂草为主，夏季（7月）以生长快、植株高和生物量大恶性杂草为主，秋季（9月）恶性杂草开始减少，酢浆草、白花蛇舌草等生物量小、株高矮的杂草逐渐增多；稻草覆盖处理茶园春、夏和秋季3个观测时期杂草物种丰富度、多样性、均匀度等指数均高于清耕对照，优势集中性指数低于清耕对照；间种白三叶草处理春、夏和秋季3个观测时期杂草总数量和生物量均显著低于清耕对照，夏、秋季杂草平均株高显著低于清耕对照；稻草覆盖和间种白三叶草处理春季茶芽重和产量显著高于清耕对照，鲜叶中游离氨基酸含量高于清耕对照，茶叶感官评审得分高于清耕对照处理。

Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.

本文对冲绳海槽北部80个表层沉积样品中的放射虫进行了系统鉴定和定量统计，研究了放射虫的种类组成与类群特征以及其丰度和分异度的分布；分析了海水温度、盐度、营养盐以及沉积物类型、成分等环境因素对放射虫分布的影响；采用Q-型因子分析，求得放射虫的属种和组合分布特征，探讨了放射虫组合与不同水团、海洋水文结构之间的关系；并对Pisias（1997）建立的估计表层海水年平均温度和其变化范围的放射虫转换函数在研究区的适用性做了检验。

The studies indicate that the abundance of Fluoranthene, Phenanthrene and Pyrene were highly correlated with the total PAHs concentrations with correlation coefficients between 0.625 to 0.999 (α=0.05), suggesting the abundance of these three compounds might be used as good indicators for the total abundance of the PAHs in the soil around the power plant.

PAHs组分中含量相对较高的Fla、Phe和Pyr 3种化合物与各组分及总量间显著相关，Pearson相关系数在0.625～0.999（α=0.05）；可以认为，Fla、Phe和Pyr是研究区燃煤电厂附近农田土壤中PAHs的特征性化合物类型。

The surveyed results show that as compared to the uncovered vegetation area, the existence of soil microbiotic crusts in the Tengger Desert region significantly increases the diversity and abundance of insect species, especially the diversity and abundance in the quadrats mainly covered by moss and lichen crusts are significantly higher than those in the quadrats mainly covered by cyanobacteria and algal crusts.

结果表明：与无结皮覆盖的植被区相比，生物土壤结皮在地表的覆盖显著地增加了昆虫的多样性和种的丰富度，其中以苔藓和地衣为主的结皮覆盖的植被样方中昆虫种的多样性和丰富度显著地高于以蓝藻和藻类为主的结皮样方。

Simple sequence repeats or microsatellites have been used as genetic markers in population genetics because of their abundance and length variation between different individuals. This study examined the SSRs in the completely sequenced Sclerotinia sclerotiorum and Botrytis cinerea genomes . The occurrences, relative abundance, relative density, most common motifs, and the longest SSRs in the two species were analyzed, and compared with other plant pathogenic fungal species, such as Fusarium graminearum, Magnaporthe grisea and Ustilago maydis .

Both three systems showed low abundance of herbivorous fishes. Relative abundance of fishes and coral reefs was least in the anthropogenically impacted systems. However, relative abundance of fishes did not differ in the protected and non-protected systems, suggesting the little effect of marine protection area.

而受人为活动影响的珊瑚礁生态系则显示，破坏的保护区之鱼类和珊瑚比例最少，但藻类最多；然而鱼类比例在保护区和非保护区间，除非是受到高度管制的保护区，鱼类比例会较高外，二区间的鱼类比例差异并不大，显示保护区可能未受到较妥当的保护，无法发挥其效能。
