| 1 | Elevational patterns of carbon,nitrogen and phosphorus in understory bryophytes on the eastern slope of Gongga Mountain,China显示文摘Aims The nutrient uptake,requirement and releasing rates of bryophytes are very different from those of tracheophytes.However,it is diffi-cult to make a quantitative evaluation of bryophytes’roles in nu-trient cycling and their specific eco-physiological adaptations due to lack of knowledge of their concentrations and stoichiometric ratios of carbon(C),nitrogen(N)and phosphorus(P).To fill this gap,the present study aims to investigate:(i)what are the elevational trends of C,N and P concentrations and stoichiometric ratios of bryophytes?(ii)whether C,N and P concentrations and stoichio-metric ratios of bryophytes differ between different bryophyte types(in terms of the growth form and living substrate)?and(iii)how do the exponent scalings of N and P of bryophytes change along the elevational gradient?Methods We measured and calculated the C,N,P concentrations and stoi-chiometric ratios of bryophytes from four elevations on the eastern slope of Gongga Mountain(22 species in total).Differences in these traits among elevations,and between different bryophyte types were compared.The log-log allometric regression parameters of N and P at each elevation were also determined and compared.Important Findings The C,N and P concentrations of bryophytes showed decreasing trends with increasing elevations.More specifically,erect bryo-phytes possessed higher C and N concentrations than those of pros-trate species,and terricolous species had higher P concentration than that of corticolous and saxicolous species.Bryophytes from different elevations had an invariant allometric regression slope for P versus N.Future research at a larger scale is in need for a more generalized law of bryophytes. | Zhe Wang Chunyan Pi Xiaoming Li Weikai Bao | 2019 | Journal of Plant Ecology2019，12，4： | 3 |
