Abstract Aims We investigated the growth and decomposition of Sphagnum, a principal plant involved in peat accumulation in wetlands, in subtropical wetlands. Methods We selected a Sphagnum-dominated wetland in southwestern Hubei Province as the study area. In situ growth and litter decomposition experiments in different microhabitats were carried out, and the chemical composition of litter was measured in laboratory to examine the processes of its growth and decomposition. Important findings The average height of Sphagnum in hummock and hollow were 2.9 and 2.7 cm, and the net production was 270.94 and 370.88 g·m -2, respectively, after 12 months. Growth time and microhabitats significantly affected on the height growth and the net production, and there was an interaction between time and microhabitats. However, the growth trend in two microhabitats was significantly different. The average growth rate of Sphagnum under the two microhabitats (July to October 2017) was 0.33 mm·d-1, which was higher than that in the cold temperate zone. In addition, the decomposition time had an significant effect on the decomposition amount of Sphagnum, and the residual rate decreased first and then increased with time. By the end 12-month period, the final residual rates in hollow, hummock and pool were 100.67%, 90.54% and 85.63%, respectively. The content of carbon (C), carbon nitrogen (N) ratio (C:N) and polyphenols in the litters decreased, while the nitrogen content increased. During the first 3 months of decomposition, a significant difference of decomposed litter was found between the microhabitats, but no significant difference later on.

DOI:10.1890/07-1822.1URLPMID:19449698 [本文引用: 2] Landscape heterogeneity causes spatial variation in disturbance regimes and resilience. We asked whether the resilience of bryophyte (liverwort and moss) assemblages to clear-cutting differs between streamside and upland boreal forests in northern Sweden. We hypothesized that bryophyte survival and recolonization rates are higher in streamside areas, thus raising resilience. Conversely, disturbance-intolerant but also invading species should be more frequent here, potentially reducing resilience. In each of 18 sites, we compared two 0.1-ha plots (one streamside and one upland) located in old forest that had never been clear-cut with two matching plots in young stands established after clear-cutting of old forests 30-50 years earlier. We used the magnitude of the difference in assemblages between old and young stands as a measure of change and, therefore, resilience (large difference implying low resilience). Species assemblages were more resilient in streamside than in upland forests. Species composition changed significantly in upland but not in streamside forests. Reductions in species richness were more pronounced in upland forests for total richness and for eight subgroups of species. Two results indicated lower survival/recolonization in upland forests: (1) species had a stronger association with old stands in upland areas, and (2) among species present in both the old streamside and old upland plot in a site, fewer appeared in the young upland than in the corresponding streamside plot. Simultaneously, a higher proportion of species invaded streamside areas; 40 of the 262 species encountered in streamside forests increased their occupancy by two or more sites compared to only two of 134 species in uplands. We suggest that in boreal forests spatial variation in resilience of assemblages of forest organisms intolerant of canopy removal is related to factors governed mainly by topography. More generally, we argue that landscape-scale variation in resilience of assemblages is influenced by spatial variation in (1) stress and resource availability, (2) number of disturbance-intolerant species, and (3) magnitude of environmental changes brought about by a disturbance with a specific intensity. We also suggest that rapid recovery in the short term does not necessarily imply higher long-term ability to return to the pre-disturbance state.

Biochemical determinants of litter quality in 15 species of Sphagnum 1 2018
... 泥炭藓的分解相比生长更为复杂, 其分解过程不仅受地表植被类型、生境、气候条件及氮沉降等环境因素的影响(Gerdol et al., 2007; Breeuwer et al., 2008; 李伟等, 2013), 同时也受不同物种间本身属性的差异(李伟等, 2013; Bengtsson et al., 2018; 刘媛媛等, 2018)和土壤养分含量的差异(Bragazza et al., 2007)所影响.本研究3种微生境下泥炭藓凋落物野外分解12个月后最终残留率平均为92.28%, 略高于刘媛媛等(2018)在长白山哈泥泥炭地的研究结果(90%).同样是泥炭藓湿地, 李伟等(2013)在长白山的研究发现泥炭藓凋落物经历14个月的分解后最终残留率为80.8%, 显著低于本研究结果.这可能与不同凋落物本身的化学属性及研究区的环境有关.研究表明, 凋落物C:N越高, 分解越快(Limpens & Berendse, 2003).与李伟等(2013)及刘媛媛等(2018)在长白山的研究相比, 本研究中泥炭藓初始C:N较低, 而分解却更慢, 这可能与本研究区凋落物本身多酚含量更高、土壤pH较低及土壤碳氮含量更低有一定关系.研究表明, 较高的多酚含量(Jassey et al., 2011)、较低的pH (Tahvanainen & Haraguchi, 2013)及较低的土壤养分含量(Bragazza et al., 2007)会抑制凋落物的分解.另外, 温度也是影响凋落物分解的一个重要因素.以往的研究表明, 较高的温度会促进凋落物的分解(Zhang et al., 2017), 也有研究认为较高的温度对凋落物的分解无显著影响(Breeuwer et al., 2008).本研究区温度显著高于寒温带地区, 然而分解率却低于寒温带地区, 可能与研究区其他环境因子对凋落物分解的抑制作用较强有关, 比如研究区土壤酸性高于寒温带地区, 凋落物多酚含量也更高. ...

... 泥炭藓湿地是由适应能力强和耐周期性干旱的泥炭藓属(Sphagnum)植物以及草本植物沼泽化形成的一种特殊湿地类型(中国湿地植被编辑委员会, 1999).由于其净初级生产力(NPP)大于分解力, 持续吸收大气中的CO2, 并积累了大量的泥炭(Gorham, 1991; Yu, 2012), 因此, 在全球碳循环中发挥着重要作用.泥炭藓属植物作为泥炭藓湿地的优势植物, 在部分地区其盖度可达100%, 其植物残体能为湿地提供巨大的生物量(Clymo & Hayward, 1982; Orwin & Ostle, 2012), 储存在泥炭藓属植物及其残体中的碳甚至高于每年固定在所有陆地植物体中的碳量(Clymo & Hayward, 1982).泥炭藓属植物是湿地土壤碳的重要来源, 其固定的碳占据了全球土壤碳库的30% (Yu et al., 2010), 在土壤碳累积过程中发挥着关键作用(Li et al., 2004; Lang et al., 2009).因此, 研究泥炭藓的生长及凋落物的分解对于揭示湿地碳循环具有重要意义. ...

Experimental climate effect on seasonal variability of polyphenol/phenoloxidase interplay along a narrow fen-bog ecological gradient in Sphagnum fallax 1 2011
... 泥炭藓的分解相比生长更为复杂, 其分解过程不仅受地表植被类型、生境、气候条件及氮沉降等环境因素的影响(Gerdol et al., 2007; Breeuwer et al., 2008; 李伟等, 2013), 同时也受不同物种间本身属性的差异(李伟等, 2013; Bengtsson et al., 2018; 刘媛媛等, 2018)和土壤养分含量的差异(Bragazza et al., 2007)所影响.本研究3种微生境下泥炭藓凋落物野外分解12个月后最终残留率平均为92.28%, 略高于刘媛媛等(2018)在长白山哈泥泥炭地的研究结果(90%).同样是泥炭藓湿地, 李伟等(2013)在长白山的研究发现泥炭藓凋落物经历14个月的分解后最终残留率为80.8%, 显著低于本研究结果.这可能与不同凋落物本身的化学属性及研究区的环境有关.研究表明, 凋落物C:N越高, 分解越快(Limpens & Berendse, 2003).与李伟等(2013)及刘媛媛等(2018)在长白山的研究相比, 本研究中泥炭藓初始C:N较低, 而分解却更慢, 这可能与本研究区凋落物本身多酚含量更高、土壤pH较低及土壤碳氮含量更低有一定关系.研究表明, 较高的多酚含量(Jassey et al., 2011)、较低的pH (Tahvanainen & Haraguchi, 2013)及较低的土壤养分含量(Bragazza et al., 2007)会抑制凋落物的分解.另外, 温度也是影响凋落物分解的一个重要因素.以往的研究表明, 较高的温度会促进凋落物的分解(Zhang et al., 2017), 也有研究认为较高的温度对凋落物的分解无显著影响(Breeuwer et al., 2008).本研究区温度显著高于寒温带地区, 然而分解率却低于寒温带地区, 可能与研究区其他环境因子对凋落物分解的抑制作用较强有关, 比如研究区土壤酸性高于寒温带地区, 凋落物多酚含量也更高. ...

Effect of pH on phenol oxidase activity on decaying Sphagnum mosses 1 2013
... 泥炭藓的分解相比生长更为复杂, 其分解过程不仅受地表植被类型、生境、气候条件及氮沉降等环境因素的影响(Gerdol et al., 2007; Breeuwer et al., 2008; 李伟等, 2013), 同时也受不同物种间本身属性的差异(李伟等, 2013; Bengtsson et al., 2018; 刘媛媛等, 2018)和土壤养分含量的差异(Bragazza et al., 2007)所影响.本研究3种微生境下泥炭藓凋落物野外分解12个月后最终残留率平均为92.28%, 略高于刘媛媛等(2018)在长白山哈泥泥炭地的研究结果(90%).同样是泥炭藓湿地, 李伟等(2013)在长白山的研究发现泥炭藓凋落物经历14个月的分解后最终残留率为80.8%, 显著低于本研究结果.这可能与不同凋落物本身的化学属性及研究区的环境有关.研究表明, 凋落物C:N越高, 分解越快(Limpens & Berendse, 2003).与李伟等(2013)及刘媛媛等(2018)在长白山的研究相比, 本研究中泥炭藓初始C:N较低, 而分解却更慢, 这可能与本研究区凋落物本身多酚含量更高、土壤pH较低及土壤碳氮含量更低有一定关系.研究表明, 较高的多酚含量(Jassey et al., 2011)、较低的pH (Tahvanainen & Haraguchi, 2013)及较低的土壤养分含量(Bragazza et al., 2007)会抑制凋落物的分解.另外, 温度也是影响凋落物分解的一个重要因素.以往的研究表明, 较高的温度会促进凋落物的分解(Zhang et al., 2017), 也有研究认为较高的温度对凋落物的分解无显著影响(Breeuwer et al., 2008).本研究区温度显著高于寒温带地区, 然而分解率却低于寒温带地区, 可能与研究区其他环境因子对凋落物分解的抑制作用较强有关, 比如研究区土壤酸性高于寒温带地区, 凋落物多酚含量也更高. ...
