The population size of the single non-pollinating fig wasp species hardly shows the negative correlations with pollinator's. The total population size of all NPFWs is positively correlated to the pollinator's. It might be the evolutionary adaptation for coexistence of the many species within a syconium.

自然种群数量分析表明，单个非传粉榕小蜂物种的种群数量几乎不与传粉榕小蜂种群数量呈负相关，而所有非传粉榕小蜂物种的种群个体总量与传粉榕小蜂的种群个体数呈正相关，这可能是多个物种共存于单个榕果内的进化适应。

In this study, we utilized the protein technology to compare the varieties of the sarcoplasmic protein, myofibrillar protein and Urea, SDS extraction of total protein profile in the 5 species of fresh filefish, including Cantherhines dumerilii, Aluterus scriptus, Aluterus monoceros, Monacanthus chinensis and Stephanolepis cirrhifer. Then, these protein profiles were employed to identify the fish species.

Widely distributed in Central America of fresh water and salt waters, the United States for the main freshwater aquaculture species. 1999 U.S. freshwater aquaculture production accounted for about 81 percent of the large warm-water species of fish, fork spots to fish tail as the Ministry of Agriculture to promote the country's fresh water breeding improved varieties have a very obvious advantages: First of Table no scales no small thorn, processing convenience and the other is the quality and refine, nutrient-rich, easy to digest and absorb the third is of miscellaneous eating habits, fast-growing, high yield, strong adaptability and easy to keep the fourth character is tame, like cluster activities , High density of aquaculture, particularly the pond custody and cage culture Fifth Tansi, easy fishing, Youdiao suitable for the development of leisure industry.

广泛分布于美洲中部的淡水和咸水水域，为美国的主要淡水养殖的品种。1999年约占美国淡水养殖总产量的81%，该鱼种是大型温水性淡水鱼类，斑点叉尾回鱼作为农业部向全国推广的淡水养殖的优良品种具有很明显的优点：一是体表无鳞没有小刺，加工方便；二是内质细嫩，营养丰富，容易消化吸收；三是食性杂，生长快，产量高，适应性强，易于饲养；四是性格温顺，喜好集群活动，可以高密度的养殖，特别是池塘主养和网箱养殖；五是贪食，易垂钓，适合发展休闲游钓业。

The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料开花以前具有比较高的根系活力、可溶性蛋白含量、SOD和CAT活性；开花以后，根系活力、旗叶可溶性蛋白含量、SOD和CAT活性快速下降，MDA含量快速上升，衰老加快；相关分析表明，延缓小麦旗叶衰老进程，可以促进花后氮素和干物质运转，增加花后氮素和干物质积累，提高籽粒产量和籽粒氮素积累量。
