“…Even with evidence that both the length of the growing season and the availability of soil moisture in the driest parts of the growing season limit growth, it is surprising that annual snowfall amount and estimated snowpack duration (from satellite imagery) had no significant effects. Though lengthening of the growing season could be expected to have positive effect on growth, most past work highlights the negative effect of earlier snowmelt on growth and abundance (Harte and Shaw 1995;Inouye et al 2000;Wipf and Rixen 2010;Klimešová, Doležal, and Št'astná 2013), with a primary reason that earlier snowmelt may expose apical buds to damage from frost (Molau 1997;Inouye 2008;Wipf and Rixen 2010). One factor that may help explain the apparent lack of effect from snow related variables is the rugged terrain of the alpine, which may cause large variation in the actual microsite accumulation and duration.…”

“…When a decreased amount of winter snowpack is coupled with an advanced snowmelt, the resulting lower springtime available soil moisture negatively effects aboveground forb biomass (Harte and Shaw 1995;Inouye et al 2000;Lambrecht et al 2007). The exact timing of snowmelt is important since snow provides insulation from freezing wind exposure in the late winter and early spring, which could kill apical buds and thus interrupt the annual growth cycle (Galen and Stanton 1995;Inouye et al 2000;Wipf and Rixen 2010;Klimešová, Doležal, and Št'astná 2013). Due to this frost damage, early snowmelt has been directly connected to decreased growth (Harte and Shaw 1995;Inouye et al 2000;Wipf and Rixen 2010).…”

“…Many herbs contain annual growth rings in their perennial underground organs (Dietz and Ullmann 1998;Dietz and Schweingruber 2002). Like dendrochronology, herbchronology finds significant variation between climate and annual growth increments of herbaceous species in montane (Dietz, von Arx, and Dietz 2004;von Arx and Dietz 2006;Klimešová, Doležal, and Št'astná 2013) and other landscapes (Liu and Zhang 2010;Dee and Palmer 2017;Hiebert-Giesbrecht et al 2017). Physiologically, belowground annual growth rings correlate with annual climatic factors because the xylem in part functions in the winter storage of photoassimilate (Wargo 1979;Lacointe 2000;.…”

The alpine ecosystem of the Rocky Mountains is experiencing significant increases in growing season length, summer maximum temperatures, and shifting patterns in precipitation. Alpine herbs are specifically sensitive to these changes. Biomass accumulation and reproductive effort are often negatively affected by elevated temperatures and earlier snowmelt. Here, we assess the use of herb-chronology, the study of annual growth rings in the woody underground organs, to retroactively monitor effects of monthly to seasonal climate on growth of the alpine forb species Penstemon whippleanus. We explored methods for building the strongest growth chronology possible by comparing the mean interseries correlations (MICs) of the whole population to that of groupings by cohorts, spatial locations, and random groupings using a permutation procedure. MIC for the whole population was low (0.034). Our permutation grouping performed best, producing a maximum MIC of 0.263. Using the permutation-derived chronology (2008-2015), we found significant decrease in growth with increased maximum temperatures in July, decreased May rainfall, increased drought between April and August, and lower minimum temperatures in September. Herb-chronology proved useful for understanding growth dynamics with climate in this alpine system; expanding this practice to similar systems could elucidate unknown effects of shifting climate on annual growth of alpine herbaceous species.

“…1). The rosette of alternate leaves is produced by an apical meristem on top of horizontally-growing epigeogenous rhizomes occurring c. 2-10 cm belowground (Klime sov a et al, 2013). The leaves surround the entire rhizome, leaving leaf scars after death.…”

Alpine plant growth and reproduction dynamics in a warmer world

et al. 2020

Climate warming may stimulate growth and reproduction in cold-adapted plants, but also reduce their performance due to warming-induced drought limitation. We tested this theory using a unique experiment with the alpine forb Rumex alpinus. We examined how climate warming over the past four decades affected its annual rhizome growth, leaf production and flowering, and whether responses varied between alpine, subalpine and montane populations. Before the period of accelerated warming in the 1970s and 1980s, the primary limitation on growth had been cold temperatures and short growing seasons. Increased summer temperatures in the 1990s and 2000s enhanced rhizome growth and leaf production, but not flowering. Alpine and subalpine plants profit more than montane plants, currently producing three times longer annual rhizome increments and twice as many leaves as 40 yr ago, and achieving nearly the same values as montane plants. During the warmest 2005-2015 period, growth became contingent on summer precipitation and began to decrease across all populations, likely due to an increasing water shortage in dense monospecific stands. Warming releases plants from cold limitations but induces water shortage. Rumex alpinus exceeds its thermal optimum and becomes water-limited as the climate warms. Our results suggest that warming-induced responses in alpine plants will not be onesided shifts to higher growth and reproduction, but rather multidimensional and spatiotemporally variable.

“…R. alpinus is a rhizomatous perennial with a horizontal rhizome growing at a depth of 5–10 cm. Because a new segment of the rhizome develops each year, the plant’s growth and age can be determined from the number of segments (Klimešová et al 2013). It has been reported that a rhizome can be as much as 120 cm long and can even persist for 35 years (Št’astná et al 2010; Št’astná et al 2012).…”

Alpine dock (Rumex alpinus) is a native plant species in many European mountain ranges. It comes from moist brushwood and open tall herb communities, though it has invaded mountain pastures. This troublesome weed forms permanent monodominant stands characterised by low nature conservation and agricultural values. However, to the best of our knowledge, there are no studies assessing the impact of R. alpinus on invaded communities. Therefore, in this study we examined the potential effect of an R. alpinus on species richness, diversity and the composition of invaded vegetation in Tatra National Park, Poland. Invaded plots dominated by R. alpinus had, compared to uninvaded control plots, significantly reduced species richness, as well as low Shannon and Simpson diversity and Pielou evenness indices’ values; the species richness decline in the pairs of invaded-uninvaded plots was as much as 37.7%. Analysing changes in diversity from an increase in R. alpinus coverage revealed that Shannon, Simpson and Pielou’s diversity indices’ values did not considerably change up to 30% of R. alpinus coverage, but a further increase in R. alpinus coverage led to a steep decline in diversity. There was exception in a number of species per plot, which decreased steadily along with the increase of R. alpinus coverage. Multivariate analysis indicated a significant shift in the composition of invaded plots in relation to uninvaded plots, resulting from the shared increase of more shadow-tolerant and higher soil base-, nutrient- and moist-demanding species.Electronic supplementary materialThe online version of this article (10.2478/s11756-018-0148-9) contains supplementary material, which is available to authorized users.
