“…This region is located in a high-elevation boreal forested zone with adequate soil moisture content. Temperature is the major limiting element for the growth of cold-land vegetation; thus, the forests in this region are less affected by the cumulative effect of drought [97,98]. This is consistent with the results of the cumulative effect of drought on global vegetation GPP, both of which have the shortest cumulative time scales in forested areas [27].…”

In the context of global warming, the strength and frequency of drought events are projected to grow in the future, and the onset of drought can have dramatic effects on vegetation growth in terrestrial ecosystems. Central Asia is the largest non-territorial drought area in the world, and the response of vegetation to drought events is extremely sensitive in the area. However, few studies have quantified and compared the vegetation gross primary productivity (GPP) response to the lagged and cumulative effects of drought. In this research, the solar-induced chlorophyll fluorescence GPP and Standardized Precipitation Evaporation Index (SPEI) were used to analyze the time and space patterns of vegetation GPP and the SPEI in Central Asia and to quantify and compare the lagged and cumulative effects of drought on the GPP of various vegetation types. During the period from 2000 to 2018, the general trends of vegetation GPP showed a slight increase in Central Asia, with the ratio of variation being 1.35 g C m−2 y−1 and a spatially decreasing distribution from north to south. SPEI showed a trend of decreasing and then increasing over a period of 19 years, with a slight decreasing (drying) trend and a rate of change of −0.02 y−1, and the overall spatial pattern was drying out from north to south. In 13 months, 72.44% of regional droughts had lagged impacts on vegetation. The maximum correlation coefficients of vegetation and the lagged effectiveness of drought were concentrated in the range of 0.15–0.35, and the high correlation was distributed in southern and northwestern Kazakhstan, which are prairie regions. Of the regions in Central Asia, 75.86% showed cumulative drought effects concentrated at 9–12 months. The maximum correlation coefficients were concentrated in the range of 0.20–0.50, and the high correlation regions were primarily situated in south Kazakhstan and east Uzbekistan. Comparing the correlation coefficients of the lagged effect of vegetation GPP and SPEI with the cumulative effect shows that the cumulative rather than lagged impacts of drought on vegetation cover were found in 86.75% of the regions in Central Asia. This research enhances our comprehension of the influence of drought events on ecosystems in arid regions and has a certain reference value for helping arid region ecosystems to cope with global climate change.

“…Since the roles of climate factors vary by month, we conducted a correlation analysis between the TRWi and the monthly temperature and precipitation indices for each month of the growing year. In order to eliminate the influence of variable autocorrelation, the first-order difference was used for the correlation analysis ( Li et al., 2021 ). Each bar or color dot in the following correlation figures means the Pearson product-moment correlation coefficient between the first-order difference of STDs and that of monthly climatic factors.…”

Understanding the factors affecting the growth of plantation forests can reduce the loss of economic and ecological values caused by plantation forest subhealth. Plantation forests are widely distributed in hilly areas with microtopographic features. Microtopography influences climatic factors associated with plant growth, during not only general time but also extreme events like droughts. However, little research has been conducted on the effects of microtopography on the plantation forest growth. In this paper, we selected Pinus tabulaeformis planted in a hilly site, and studied the effect of microtopography on the climate–growth relationship and drought response of a typical plantation in Northeast China using dendroecological methods. We found: 1) Between hill positions, temperature caused a climatic growth difference. Compared to the hilltop, the correlation of annual growth on the hillside with monthly temperature was more negative in July–August and less positive in January–April. 2) Between aspects, precipitation intensities caused a climatic growth difference. Compared to the sunny slope, the correlation of annual growth on the shady slope with monthly total precipitation below 10 mm/day was less positive (May–June) or more negative (March–April and July), while that with monthly total precipitation above 10 mm/day was more positive in most months.3) Drought response varied significantly based on hill position and aspect. There was no significant difference in resistance between hill positions, while recovery and resilience on the hilltop were greater than those on the hillside.Resistance, recovery, and resilience were all lower on the sunny slope than those on the shady slope. Overall, microtopography exists the effects on the growth of plantation forests, both in terms of climate-growth relationships in general climate and in response to drought when extreme events. Meanwhile, the climatic factors that caused the difference in growth of plantation forests between hill positions and aspects differed. The difference in growth between hill positions was caused by temperature, while that between aspects was caused by precipitation intensity. Drought response difference reflected the legacy effect of drought on plantation growth, which could lead to subsequent changes in climate-growth relationships. These findings demonstrate that strengthening the research of forest trees on microtopography is necessary for accurate carbon sink assessment and precise forest management.

“…La finalización tardía de la estación de crecimiento puede representar una desventaja para los brotes debido a la probabilidad mayor de sufrir daños por heladas tempranas (Lindner et al, 2010). Los árboles de P. hartwegii en el presente estudio tuvieron un periodo promedio de crecimiento similar al de los árboles de P. sylvestris L. mongolica (151 días) en las montañas Hinggan en China (Li et al, 2021), pero mayor al de los árboles de P. halepensis Mill. (125 días) en el sur de Cataluña, España (Camarero et al, 2022).…”

“…El crecimiento de las plantas de P. hartwegii está influenciado por condiciones climáticas locales como variación en temperatura, disponibilidad de humedad e intensidad y frecuencia del viento, como en otras especies que crecen en ecosistemas de altas elevaciones en las zonas montañosas (Case y Duncan, 2014). La temperatura cumple un papel importante en la fenología y crecimiento de las especies de árboles dominantes y en consecuencia en la estructura y función de los bosques de coníferas en zonas frías y templadas (Li et al, 2021). El cambio climático influye en eventos fenológicos de las plantas, como en el periodo de crecimiento, fecha de rompimiento de latencia de las yemas en primavera y terminación de crecimiento de los brotes en verano (Jeong et al, 2011;Shen et al, 2014).…”

Pinus hartwegii crece aproximadamente entre 3000 y 4200 msnm en el límite de la vegetación arbórea en las montañas de México y América Central. Es importante analizar el hábito de crecimiento de los árboles y la posibilidad para adaptarse a los cambios ambientales. De acuerdo con lo anterior, el objetivo del presente estudio fue comparar el crecimiento del brote apical de plantas de P. hartwegii en unidades de muestreo en tres altitudes en la montaña Tláloc por un año. Se establecieron tres unidades de muestreo de 1000 m2 a 3629, 3824 y 4012 msnm en esta montaña en Texcoco, Estado de México. Se midieron el diámetro y longitud de los brotes apicales de las plantas menores de 2.5 m de altura cada 30 días. Se registró el crecimiento del brote entre mayo de 2021 y mayo de 2022. Se detectaron diferencias significativas (P ≤ 0.05) entre altitudes para las características estudiadas. Los diámetros promedio de los brotes variaron entre 15.14 ± 0.59 y 22.65 ± 0.73 mm. Las longitudes promedio de los brotes fueron de 10.87 ± 0.93 a 19.53 ± 2.37 cm. Los brotes apicales iniciaron el crecimiento, en promedio, entre los 74 ± 2.20 y 101 ± 6.60 días del año, y finalizaron, en promedio, entre los 214 ± 6.57 y 263 ± 9.71 días del año. El periodo de crecimiento varió en promedio entre 125 ± 13.86 y 177 ± 9.80 días. La correlación entre el diámetro del brote y la precipitación media anual fue moderada (r = 0.605, P ≤ 0.0001). La longitud promedio y diámetro promedio del brote fueron mayores a los 4021 msnm. El brote apical inició el crecimiento primero en las plantas a los 3629 msnm y finalizó el crecimiento al último en las plantas a los 4021 msnm donde el periodo de crecimiento fue mayor.
