Spinulosa gradually increased with the increase of water depth when the water depth was less than 2 meters, the biomass of V.

水深2 m以下，随着水深的增加，刺苦草的地上生物量和地下生物量逐渐增加；水深超过2 m后，生物量显著减少，刺苦草的有性繁殖受限。

Historically, extensive hydrologic connectivity among populations might have facilitated long-distance gene flow and resulted in the pattern of genetic variation revealed in this study, and also played great roles in population dynamics and population persistence of V. spinulosa in this region.

长江中下游湖泊与长江干流历史上高的连通性对刺苦草在这一区域的遗传多样性水平和遗传结构形成起了重要的作用；同时，历史上的江湖一体化格局也促进了刺苦草在这一区域的种群扩散和维持。

In order to investigate the effects of different shading levels (Shading levels were: control 0, 50%, 80%, 90%) on the trade-off relations between sexual reproduction and clonal multiplication of Vallisneria spinulosa, a natural greenhouse experiment was carried out by winter tuber of Vallisneria spinulosa being collected from Poyang Lake in the Jiangxi Province.

以采自江西鄱阳湖的刺苦草冬芽为实验材料，在自然温室中经历了全不遮阳、部分遮阳等4种处理，研究不同遮阳处理产生的光线差异对刺苦草的有性繁殖和无性繁殖方式的资源配制的影响。

Pipiens pallens occurred in 1-1.5 hours after sunfall, the latter was later and was in 20 mins.

三带喙库蚊和淡色库蚊的叮刺高峰一般是在日落后11.5h，持续约30min，淡色库蚊的叮刺高峰略迟20min。

From the appearance characteristics of plant community,the synusia structure of plant community in Minqin desert grassland was composed of simple herbaceous and shrub layer,and individual plants was dwarf,small crown,low biomass,with an average altitude of 0.60 m and lower than 1.00 m~2 crown;except for Nitraria,Zygophyllaceae and Caragana,the fresh weight of per plant biomass of most plant were below 1000 g / individual.

8从植物群落的外貌特征来看，民勤荒漠草地各植物群落的层片结构是由简单的灌木层和草本层组成，且植物个体矮，冠幅小，生物量低，平均高度在0.60m以下，冠幅在1.00m~2以下；生物量除了白刺、泡泡刺和柠条外，大多数植物的单株生物量鲜重都在1000 g/株以下。

At least two subspecies, the Quill Rat and the Thorned Beast, are known to fire their quills without provocation.

目前所知至少有两个种类，硬毛老鼠和多刺野兽，会不经挑釁而直接发射牠们的刺。
