“…One of the features of the climate of the studied area is that cooler years are usually related to increased precipitation and high temperature can reflect droughts to some degree [70]; this could represent a link between the results of this study and the study of Feliksik [28]. A negative influence of temperature was also found for the previous July (Figure 6a), which is in agreement with other studies from Poland and Lithuania [66,67,71], where an adverse effect of the previous summer's temperature was recorded. This effect could be related to water stress, temperature impact on respiration, bud initiation, and other processes that can reduce carbohydrate reserves [71].…”

“…It could be conjectured that it starts earlier at lower elevations. For most of the study sites the positive response to temperature is usually restricted to May; a similar response has been observed for larch growing in the lowlands of central and northeast Poland [66] and Lithuania [67]. For some locations the positive influence of a warm April was also observed, similarly as observed for larch from Lithuania [67].…”

“…Similarly, in a study from an experimental plot in mid-east Poland [71], tree-ring growth of larch was mainly related to summer precipitation and was explained by the high water needs of larch (e.g., [75,76]. A positive influence of summer precipitation (mainly June-July, but sometimes also May) was recorded for sites in other regions of Poland located north of the study area [60,66,77] and Lithuania [67]. In the presented study, a mainly positive response to July precipitation is indicated; however, significant correlations were recorded only for some of the analyzed sites (Figure 6b).…”

Abstract:The climate-growth relationship of larch (Larix decidua Mill.) in the Polish Carpathian Mountains was studied. We explored the spatial variability of the common signal observed in larch tree-ring growth, distinguished regions with uniform tree-ring growth patterns (dendrochronological signal), and determined the climatic factors that are particularly important for the growth of larch in this area. Uniformity in the growth reaction across the analyzed area was found in the positive response to May temperatures (significant correlation values range from 0.21 to 0.48); this indicates that the warm beginning of the growing season is important for larch growth across the study area. The signal variability from west to east found in the principal components analysis (PCA) results and differences in climate response between analyzed sites suggest their relation to increasing influence of the continental climate to the east. However, the observed relationship is not stable and does not occur systematically. Although the climate-growth response of larch at lower elevations is highly variable, a positive influence of July precipitation and a negative influence of April precipitation, and previous May and July temperature can be observed. The growth of larch from the highest study sites (Tatra Mountains, above 950 m a.s.l.) is related to temperature. This is manifested by a strong positive correlation with temperature during late spring, early summer, and the end of the previous growing season, and a negative or no response to late spring/summer precipitation. No relation between the observed correlations and slope aspect was found.

“…A dendrochronological study on European larch (Larix decidua Mill.) in Lithuania indicated that precipitation during the vegetation period was the most important environmental factor influencing growth during the pointer years (Vitas 2015). In this study tree-ring width of European larch positively correlated with precipitation in June and with air temperature in April and May, but showed negative correlation with air temperatures of the previous summer (Vitas 2015).…”

Climate-growth relationships and pointer year analysis of a Siberian larch (Larix sibirica Ledeb.) chronology from the Mongolian mountain forest steppe compared to white birch (Betula platyphylla Sukaczev)

et al. 2017

Background: Forest area, stand quality and growth of Siberian larch in Mongolia have decreased significantly over recent decades. This forest decline is frequently attributed to factors such as unregulated logging, increased ecological disturbances (primarily fire) and climate change. In this study, we analyzed climate-growth response and pointer years for Siberian larch observed in the Altansumber forest research area in the Mongolian mountain forest steppe zone. We compare our results with previously published results of white birch from the same area. Methods: We built a reference chronology from wood core samples taken from 30 trees in three neighboring larch stands. Climate-growth relationships were analyzed monthly and seasonally over the period 1962-2009 using climate data from the Eroo weather station. Pointer year analysis covered the same time frame. Results: Our analysis of the larch chronology showed that precipitation during autumn of the previous year and directly before the growing season of the current year was the most decisive factor determining tree-ring growth. Regional pointer year analysis further indicated that a humid summer and autumn followed by a warm spring support current-year tree-ring growth in these larch stands. Our findings were comparable to a white birch study in the same area. The larch trees, however, showed stronger growth performance and were more tolerant of higher temperatures, notably in spring during peak fire season.Conclusions: Water availability is the decisive factor for larch growth in the mountain forest steppe zone. The chronologies showed no climatic indication of insect infestations. Differences in climate-growth relationships of birch and larch trees during peak fire season may to some degree be explained by their respective means of protecting themselves against low-intensity surface fires (e.g. thick bark of larch). These fire events occur regularly in the region and are influenced by climatic factors. Our analysis and comparison of climate tree-growth relationships may be valuable for developing climate-and disturbance-resilient forestry practices in Mongolian mountain forest ecosystems.

Phenotypic Plasticity (abbreviated as PP in the article) commonly refers to the ability of a genotype (an individual's gene collection) to adjust its phenotype (the set of observable traits of the same individual) under different environmental conditions (Arnold et al., 2019;Bradshaw, 1965;Pigliucci & Pigliucci, 2001). This mechanism plays a crucial role for the development and survival of individuals facing new adverse environmental conditions (Silvestre et al., 2012), especially if we refer to sedentary and long-living organism such as forest trees (Bradshaw, 1965;Santini et al., 2018). Due to their long existence, trees have to face climatic fluctuations of variable frequencies and intensities (Rehfeldt et al., 2001) and thus have higher chances to come across extreme weather events. PP however is also a very important mechanism to adapt to rapid environmental change
