“…The growth of P. pumila in the south is limited by temperature during the growing season. This might be because the average elevation of the southern sampling sites (1,310 m) is higher than that of the central and northern sites; average annual precipitation is also greater (Li et al, 2020). Therefore, moisture is not the main factor limiting the growth of P. pumila in the southern part of the study area.…”

“…The positive correlations between P. pumila growth and minimum temperature highlight the importance of winter and spring temperatures in the north (Figure 4). Frost may affect shrub growth at high latitudes before the growing season (Li et al, 2020). In a cold environment, spring temperatures and the length of the growing season are important factors limiting the production and differentiation of xylem cells (Morales et al, 2012;Lenz et al, 2013;Yang et al, 2020).…”

Understanding the responses of shrub growth to climate changes is key to accurately predicting the dynamic changes in the boreal forest ecosystem. A shrub-ring network based on 12 sites was established to explore the response of Pinus pumila growth to climate change in northeastern China. The sampling sites are distributed along the latitudinal gradient of 44.10° to 52.58° and were divided into three regions: south, central, and north. The results show that there have been significant differences in P. pumila growth trends at different latitudes in recent decades. From 1950 to 1980, P. pumila in the southern and central regions grew faster than in the northern region. From 1981 to 2014, however, the growth of P. pumila increased in the north but slowed in the south and central regions. The temperatures of the previous winter and current spring are the main factors limiting the growth of P. pumila in the north and south. In the central and southern regions, the growth of P. pumila is negatively correlated with precipitation of the previous and current summers. In the north, summer temperatures from 1981 to 2014 gradually inhibit the growth of P. pumila, while summer precipitation has a positive impact on growth. Our model indicates that the radial growth trend of P. pumila in the north is likely to decline as the climate warms. Surprisingly, the growth of P. pumila in the south is predicted to benefit from warming under the RCP4.5, RCP6.0, and RCP8.5 scenarios. Therefore, P. pumila may not expand northward in the context of climate warming.

“…In contrast, elevated nighttime temperature has been found to increase nighttime plant respiration and leaf photosynthesis during the following day through a reduction in carbohydrate feedback inhibition [11,16]. Moreover, warmer growing-season temperature favors tree growth in northern boreal forest that is limited by cold temperature but the effect can shift to be negative in southern boreal forest [17][18][19][20]. In contrast, climate warming during the non-growing season affects spring phenology and thereby tree growth during the following growing season [12].…”

Climate change is exerting profound impacts on the structure and function of global boreal forest. Compared with their northern counterparts, trees growing at the southern boreal forest and the temperate-boreal forest ecotone likely show distinct responses to climate change. Based on annual basal areal increment (BAI) of Dahurian larch (Larix gmelinii Rupr.) plantations with similar ages, tree densities and soil nutrient conditions, we investigated the tree growth responses to inter-annual climate variations at an Asian temperate-boreal forest ecotone and nearby boreal sites in northeast China. Annual BAI changed nonlinearly with cambial age in the form of a lognormal curve. The maximum annual BAI showed no significant difference between the two bioregions, while annual BAI peaked at an elder age at the boreal-temperate forest ecotone. After eliminating the age associated trend, conditional regression analyses indicate that residual BAI at the boreal sites increased significantly with higher growing-season mean nighttime minimum temperature and non-growing-season precipitation, but decreased significantly with higher growing-season mean daytime maximum temperature during the past three decades (1985–2015). In contrast, residual BAI at the boreal-temperate forest ecotone only showed a positive and weak response to inter-annual variations of growing-season precipitation. These findings suggest distinct effects of inter-annual climate variation on the growth of boreal trees at the temperate-boreal forest ecotone in comparison to the southern boreal regions, and highlight future efforts to elucidate the key factors that regulate the growth ofthe southernmost boreal trees.

[Ecosistemas no se hace responsable del uso indebido de material sujeto a derecho de autor] Relación de la variabilidad climática con el crecimiento diamétrico de ocho especies arbóreas de bosque seco en Costa Rica Introducción El crecimiento de las plantas se produce por la captura de carbono en el proceso de fotosíntesis; allí se generan azúcares que posteriormente son distribuidos a los diferentes compartimentos del individuo (Van der Maaten et al 2016); en el caso de los árboles, en el fuste los azúcares, en su mayoría, son transformados en celulosa, hemicelulosa y lignina, elementos que constituyen el tejido leñoso conocido como madera (Li et al 2020). Particularmente, el crecimiento diamétrico se correlaciona con la captación de carbono atmosférico (Hu et al 2018), debido a que el cambium genera nuevas estructuras de floema y xilema en los cuales se almacena carbono (i.e.…”

Factores como patógenos, daños mecánicos, disponibilidad de nutrientes, características químicas y físicas del suelo, y en especial la influencia del clima inciden en la capacidad de absorción de carbono, lo cual afecta directamente en el crecimiento del individuo y, por lo tanto, el desarrollo del bosque o ecosistema (Wang y Hamzah 2019).…”

El crecimiento de árboles en el bosque seco tropical tiene una relación significativa con el clima el crecimiento se desarrolla en la época lluviosa y en época seca el crecimiento se estanca. Sin embargo, son pocas las especies con las que se cuenta de estudios de crecimiento. Por tanto, el estudio caracterizó los efectos de la variación climática en el crecimiento diamétrico (Cd) de las ocho especies arbóreas de mayor importancia en un bosque seco tropical en Costa Rica. Se seleccionaron 12 árboles por especie, en los cuales se midió el Cd entre el 2015 y el 2018, complementado con mediciones climáticas (temperatura, precipitación, humedad relativa y horas luz) y determinación de la densidad de la madera (Dm). Se desarrollaron ecuaciones de Cd con variables climáticas y se evaluaron relaciones de Dm con Cd. Los resultados mostraron que el Cd anual es de 3.04 mm en Albizia niopoides; 2.83 mm en Bursera simaruba, 2.07 mm en Cordia alliodora, 1.92 mm en Cordia panamensis, 0.68 mm en Hymenaea courbaril; 3.82 mm en Luehea speciosa; 1,63 mm en Machaerium biovulatum y 0,30 mm en Handroanthus impetiginosus; se encontró una fase de crecimiento en la estación lluviosa y leves contracciones diamétricas en la estación seca. Con la correlación significativa de Cd con precipitación y temperatura media anual se determinó una relación positiva entre Dc y precipitación y negativa entre Cd y temperatura promedio, lo cual permitió desarrollar ecuaciones lineales de predicción de crecimiento con R2 superiores a 0,61 y errores menores a 1,00. Finalmente, se determinaron relaciones entre Cd y Dm; conforme Dm fue menor se obtuvieron mayores Cd.
