在不列颠哥伦比亚省北部沿海的一个倾斜的开放泥炭地，研究了Racomitrium lanterosum，Pleurozium schreberi，Sphagnum austinii，Sphagnum fuscum，Sphagnum rubellum，Sphagnum papillosum，Sphagnum lindbertum，Sphagnum tenellum和Sphagnum pacificum的年内生长模式与当地降水和温度的关系。藓类植物的生长与降水量有很强的相关性，与温度的相关性较小。温度对生长的影响，建议强调生长和降水和温度的组合之间的相关性。泥炭藓的温度阈值。的含量低于P、schreberi和R.羊毛脂泥炭藓的生长速率。的季节性生长模式比空心泥炭藓和草坪泥炭藓少。尽管低垂直增长率，丘泥炭藓属。其生产力高于空心泥炭藓和草坪泥炭藓。冬季生长在这个超海洋区域似乎是重要的。
Intra-annual growth patterns of Racomitrium lanuginosum, Pleurozium schreberi, Sphagnum austinii, Sphagnum fuscum, Sphagnum rubellum, Sphagnum papillosum, Sphagnum lindbergii, Sphagnum tenellum, and Sphagnum pacificum were studied in relation to local precipitation and temperature in a sloping open peatland on the hypermaritime north coast of British Columbia. The growth of mosses was strongly correlated with precipitation and less with temperature. A temperature effect on growth was suggested by the emphasized correlation between growth and a combination of precipitation and temperature. Temperature thresholds for Sphagnum spp. were estimated to be lower than those for P, schreberi and R. lanuginosum. Growth rates of hummock Sphagnum spp. were lower and the seasonal growth pattern was less variable than those of hollow and lawn Sphagnum spp. Despite low vertical growth rates, hummock Sphagnum spp. had higher productivity than hollow and lawn Sphagnum spp. Winter-growth in this hypermaritime region appears to be important.
