“…High gibberellin accumulation could reduce the number of bamboo shoots withdrawn ( Chen et al., 2022 ). In addition, it was found that stronger light was beneficial to clone plants to produce more ramets ( Li et al., 2018 ). The gap was formed in the bamboo forest after cutting, and the temperature heterogeneity of the stratum was good ( Shen et al., 2020 ).…”

Strip cutting can effectively reduce the cutting cost of bamboo forests and promote the transformation and upgradation of bamboo forests through mechanization and modernization. Despite the rapid accumulation of Moso bamboo biomass, the dynamics of five years changes in stand characteristics and productivity after cutting remain unclear. This is critical for formulating efficient bamboo forest management measures. In this paper, plots with an 8 m width strip cut (SC) and respective reserved belts (RB) were selected as the research object, and the traditional management forest (CK) as control. The dynamic characteristics of stand, biomass distribution pattern, and productivity change in the different treatment plots were studied for 5 years after cutting. The results showed that cutting increased the number of shoots and new bamboo, and decreased the diameter at breast height, height to crown base, and height of new bamboo (p<0.05). Cutting reduces the productivity of both SC and RB, and allocates more biomass to the bamboo leaves to capture light in SC (p<0.05). Over time, the characteristics of new bamboo in SC reached the level of CK, and the density of standing bamboo, and productivity, were higher than those in CK. However, the number and productivity of new bamboo decreased significantly in the RB (p<0.05), which reflected the density restriction effect of bamboo forest. Further analysis showed that the increase in productivity in SC and CK was mainly from Moso bamboo at II and III “du”, which positively correlated with the soil contents of total nitrogen, total phosphorus, and available phosphorus. It was suggested that after three On-year restorations, the SC could reach the level of CK, however it is necessary to density manage RB from the second On-year after cutting.

“…Research shows that, for example, clonal plants can sense the heterogeneity of their microenvironment and make choice between qualitatively different patches by placing ramets to beneficial patches (Bazzaz, 1991;Hutchings and John, 2004;Roiloa and Retuerto, 2012;Oborny and Hubai, 2014;Waters and Watson, 2015). Such foraging behavior likely belongs among the important characteristics enabling the dominance of clonal plants in many ecosystems (Wang et al, 2016;Waters et al, 2016;Dong et al, 2018;Li et al, 2018;Latzel and Münzbergová, 2018;Quan et al, 2018;Chen et al, 2019). Majority of studies explained the microhabitat foraging behavior of clonal plants by morphological plasticity and/or photosynthetic adjustments (Salzman, 1985;Evans and Cain, 1995;Wijesinghe and Hutchings, 1999;Roiloa and Retuerto, 2006a,b,c;Xiao et al, 2006Xiao et al, , 2011Waters and Watson, 2015;Waters et al, 2016;Ye et al, 2015;Quan et al, 2018).…”

Ultraviolet B Radiation Triggers DNA Methylation Change and Affects Foraging Behavior of the Clonal Plant Glechoma longituba

Clonal plants in heterogeneous environments can benefit from their habitat selection behavior, which enables them to utilize patchily distributed resources efficiently. It has been shown that such behavior can be strongly influenced by their memories on past environmental interactions. Epigenetic variation such as DNA methylation was proposed to be one of the mechanisms involved in the memory. Here, we explored whether the experience with Ultraviolet B (UV-B) radiation triggers epigenetic memory and affects clonal plants’ foraging behavior in an UV-B heterogeneous environment. Parental ramets of Glechoma longituba were exposed to UV-B radiation for 15 days or not (controls), and their offspring ramets were allowed to choose light environment enriched with UV-B or not (the species is monopodial and can only choose one environment). Sizes and epigenetic profiles (based on methylation-sensitive amplification polymorphism analysis) of parental and offspring plants from different environments were also analyzed. Parental ramets that have been exposed to UV-B radiation were smaller than ramets from control environment and produced less and smaller offspring ramets. Offspring ramets were placed more often into the control light environment (88.46% ramets) than to the UV-B light environment (11.54% ramets) when parental ramets were exposed to UV-B radiation, which is a manifestation of “escape strategy.” Offspring of control parental ramets show similar preference to the two light environments. Parental ramets exposed to UV-B had lower levels of overall DNA methylation and had different epigenetic profiles than control parental ramets. The methylation of UV-B-stressed parental ramets was maintained among their offspring ramets, although the epigenetic differentiation was reduced after several asexual generations. The parental experience with the UV-B radiation strongly influenced foraging behavior. The memory on the previous environmental interaction enables clonal plants to better interact with a heterogeneous environment and the memory is at least partly based on heritable epigenetic variation.

“…The reverse trend in declining nitrogen might be due to translocation of nitrogen to other parts of rhizomes, which was previously found in clonal plants (Evans 1988;Eckstein and Karlsson 1999). In addition, clonal integration was found to signi cantly increase nitrogen availability in the rhizosphere of offspring culms but decrease in mother culms through responses of soil microorganisms (Li et al 2018). Nitrogen is crucial to increase plants' photosynthetic performance under low light conditions (Luo et al 2022), and thus translocation of nitrogen is necessary to balance carbon budget among culms within the colony, especially for young culms waiting in the understory under stronger interspeci c competition.…”

Contexts The invasion of fast growing Phyllostachys edulis (Moso bamboo) into forest is likely further favored by climate change, creating more transitional regions within forests. Such forest-bamboo transitional zones provide windows to look at ecological processes driving bamboo’s interaction with competing species across space. Objectives We tested the hypothesis that spatial patterns at scales of ecotone and individual stems can inform bamboo’s invasive spread and its competitive engulfing strategy, with the allocation of biomass and resources within a bamboo colony being a key life-history strategy to facilitate its spatial spread. Methods We used remote sensing imagery and field survey data to analyze the dynamics of bamboo-tree transitional boundaries in Tianmu Mountain Nature Reserve (TMNR) of southeastern China. We evaluated bamboo’s invasive spread and its allocation of resources along the transitional gradient. Results Both remote sensing and field data showed bamboo recovery and advancement into tree territories after the extensive logging of bamboo but with a slower spread compared to historical records. The spatial distributions of bamboo and tree stems were not random at their transitional interfaces and were affected by competition. Successful invasion of bamboo required close coordination between stems and rhizomes within a colony, as they served different functions in clonal integration. Conclusions Our study initiates a mechanistic, scale-dependent analysis of bamboo invasion strategies, which provides insights on how to accurately predict future bamboo distributions under climate change accounting for interspecific competition and bamboo’s clonal integration of resources.
