The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

The forest communities with this species can be divided into six groups, which are Cyclobalanopsis stewardiana-Sinarundinaria nitida community, Cyclobalanopsis stewardiana + Quercus engleriana + Carpinus viminea-Sinarundinaria nitida community, Cyclobalanopsis stewardiana-Euryia brevistyla community, Rhododendron ririei + Cyclobalanopsis multinervis-Illicium simonsii community, Fagus lucida + Cyclobalanopsis multinervis + Cyclobalanopsis stewardiana-Sinarundinaria nitida community and Cyclobalanopsis stewardiana-Camellia cuspidata-Illicium simonsii community respectively.

通过使用双向指示种分析和无偏对应分析两种方法进行研究的结果表明，梵净山树干附生尖叶拟船叶藓在群落水平上的分布与森林群落类型相对应，其所在群落可以分成贵州青冈－箭竹群落、贵州青冈＋巴东栎＋雷公鹅耳枷－箭竹群落、贵州青冈－短柱柃群落、大钟杜鹃＋多脉青冈－野八角群落、亮叶水青冈＋多脉青冈＋贵州青冈－箭竹群落和贵州青冈－尖叶山茶－野八角群落6类树附生苔藓植物群落类型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
