“…These results were analogous to previous findings at the same study site, which found that warming had no effect on TRB and FRP of P. densiflora seedlings [23,28]. The absence of the warming effects on FRP, FRM, and root biomass might result from physiological adaptations of leaves to heat and drought stresses.…”

Air warming (TC: control; TW: +3 • C) and precipitation manipulation (PC: control; PD: −30%; PI: +30%) were established to examine effects of these treatments on fine root production (FRP), fine root mortality (FRM), and total root (coarse and fine root) biomass in 33-to 59-month-old Pinus densiflora Sieb. et Zucc. seedlings for two years. We hypothesized that warming and altered precipitation would affect the growth, death, and biomass of fine roots by changing soil temperature and soil water availability. Mean annual FRP and total root biomass were significantly altered by only precipitation manipulation: they were 29.3% (during the two-year period) and 69.0% (after the entire two years) higher, respectively, in PD plots than in PC plots, respectively. In contrast, only warming had a significant effect on mean annual FRM, being 13.2% lower in TW plots than TC plots during the two-year period. Meanwhile, fine root biomass was affected negatively and simultaneously by both soil temperature and soil moisture. It seemed that fine root dynamics have changed so that they maintain their systems in response to the altered soil temperature and moisture. The current study adds significant knowledge for understanding the fine root dynamics of P. densiflora seedlings under altered temperature and precipitation regimes.

“…Consistent with the different growth responses observed among species in this study, other species of the genera Pinus and Abies showed different growth responses following warming (Wang et al, 1995;Tjoelker et al, 1998;Zhao and Liu, 2009a;Wang et al, 2012;Yang et al, 2013). While RCD, seedling height, and total biomass of first-year P. densiflora increased under warming in this study, those of 2-4-year-old P. densiflora were not found to differ in response to warming in a previous study (Lee et al, 2013). This discrepancy might result from the effect of the growth stage and ontogenetic drift (Saxe et al, 2001).…”

Temperature increase due to climate change may affect the growth and physiological traits of trees. To cope with climate change, it is important to understand the responses of trees to these changes, as well as how these responses vary among species, functional groups, and biomes. In this study, we aimed to examine the species-specific growth and photosynthetic responses of firstyear seedlings of 4 coniferous species to future temperature increase by conducting an open-field experimental warming study. The air temperature in the warmed plots was maintained at 3.02 °C higher than that in the control plots with an open-field experimental warming system. The seeds of Pinus densiflora, Pinus koraiensis, Abies holophylla, and Abies koreana were planted in 2012, and the effects on growth, biomass allocation, leaf area, net photosynthetic rate, and chlorophyll contents of first-year seedlings were measured. Compared to the other species, P. densiflora showed pronounced responses to warming after the growing period, including increase in root collar diameter (RCD) and seedling height respectively by 10% and 6%, total biomass by 45%, net photosynthetic rate by 61%, and total chlorophyll content by 45%. For P. koraiensis, RCD, seedling height, and total chlorophyll contents increased by 7%, 5%, and 20% in warmed plots, respectively. A. holophylla showed an increase in RCD by 7%, whereas A. koreana responded inconsistently to warming. Changes in the seedling height to diameter ratio, organ-specific biomass, leaf area, and specific leaf area were also species-dependent. In addition, altered growth throughout the observation period was due to acclimation and phenological change. This suggests that speciesspecific growth responses to warming are affected by altered net photosynthetic rate, chlorophyll contents, and leaf area. Species-specific responses of first-year seedlings of 4 coniferous species to warming and the relationship between growth and photosynthesis might be applied to estimate the growth and distribution of coniferous species after future temperature rises.

“…P. densiflora can endure drought and barrenness, is an excellent pioneer species for secondary succession, and, thus, is crucial for reforestation and soil and water conservation [30]. The seed propagation of P. densiflora can be used for reforestation in the steeper barren hills.…”

Pinus densiflora is an important evergreen coniferous species with both economic and ecological value. It is an endemic species in East Asia. Global climate warming greatly interferes with species survival. This study explored the impact of climate change on the distribution of this species and the relationship between its geographical distribution and climate demand, so as to provide a theoretical basis for the protection of P. densiflora under the background of global warming. This research used 565 valid data points and 19 typical climatic environmental factors distributed in China, Japan, and South Korea. The potential distribution area of P. densiflora in East Asia under the last glacial maximum (LGM), mid-Holocene, the current situation and two scenarios (RCP 2.6 and RCP 8.5) in the future (2050s and 2070s) was simulated by the MaxEnt model. The species distribution model toolbox in ArcGIS software was used to analyze the potential distribution range and change of P. densiflora. The contribution rates, jackknife test and environmental variable response curves were used to assess the importance of key climate factors. The area under the receiver-operating characteristic curve (AUC) was used to evaluate model accuracy. The MaxEnt model had an excellent simulation effect (AUC = 0.982). The forecast showed that the Korean Peninsula and Japan were highly suitable areas for P. densiflora, and the area had little change. Moreover, during the LGM, there was no large-scale retreat to the south, and it was likely to survive in situ in mountain shelters. The results suggested that Japan may be the origin of P. densiflora rather than the Shandong Peninsula of China. The distribution area of P. densiflora in the mid-Holocene and future scenarios was reduced compared with the current distribution, and the reduction of future distribution was greater, indicating that climate warming will have certain negative impacts on the distribution of P. densiflora in the future. The precipitation of the warmest quarter (Bio18), temperature seasonality (Bio4), mean annual temperature (Bio1) and mean temperature of the wettest quarter (Bio8) had the greatest impact on the distribution area of P. densiflora.
