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.

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.
