弹尾目昆虫对重金属污染的反应，不同的种之间有很大的差别，其中，裸长角属对Cu污染反应不灵敏，陷等属、棘属对Cu污染反应敏感，随着污染程度的加剧，它们的数量明显减少；小等属和长属对Cu、Zn、Cd、Pb等重金属元素的复合污染反应很敏感，而裔符属、球圆属、土属、圆属和鳞长属对重金属复合污染反应很迟钝，在这些重金属复合污染严重的农田中仍能很好地生存繁衍。

Numerically, Limacina trochiformis was the main dominant specis in spring, attributed to its low temperature adaptation. Atlanta peroni was the dominant species in summer and Creseis acicula was the dominant species in autumn due to their adaptation to relatively high temperature. Agadina stimpsoniji was the dominant species in winter, adapted to low temperature.

Before the treatment of drought stress, most of communities can be classified into following seven types with biomass of dominant species which took account of 60% in the plots: Triumfetta bartramia, Urena lobata, Cynodon dactylon, Gahnia tristis, Ageratum houstonianum, A/rtemisia argyi and Ambrosia artemisiifolia. There was no dominant species in other communities. Totally, there are 33 common species distributed in these plots.

在群落自然生长一年后，根据群落内物种生物量所占比例，将样地群落划分为七个优势物种类型(优势物种生物量所占比例均在60%以上，盖度在群落内均最大)：刺蒴麻、肖梵天花、狗牙根、黑莎草、藿香蓟、家艾和豚草，其余为均匀度较高没有优势物种的样地。

While the adsorptions of 1-propanol and 1-Br-propane at 100℃ give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 ℃ shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150℃, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO〓 catalyst.

2原位IR光谱实验结果表明：200℃时丙烷/O〓混合气在催化剂表面吸附后的IR谱与同温度下异丙醇吸附的IR谱相似，均检测到吸附态丙酮物种和丙烯醛物种的IR谱峰；溴代异丙烷和异丙醇在催化剂表面吸附后均转化为异丙氧基，异丙氧基主要转化为丙烯和丙酮，丙烯进一步转化为丙烯醛；溴代正丙烷和正丙醇在催化剂表面吸附后均转化为正丙氧基，正丙氧基主要转化为丙醛；丙烯在催化剂表面吸附后转化为σ-氧烯丙基和异丙氧基，升温后σ-氧烯丙基转化为丙烯醛而异丙氧基转化为丙酮。

While the adsorptions of l-propanol and 1-Br-propane at 100 癈 give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 癈 shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150 癈, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO2 catalyst.

In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.

我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异，经由子叶面积大小的测量，欧洲苦苣苔成员两片子叶呈现相似的生长速率，因此维持两片子叶等大的特徵，然而堇兰的大小子叶的确具有不同的生长速率，使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。
