“…The wood cores were dried at room temperature, mounted, and polished with successive coarse-grit sandpapers (100 and 360) and four finer-grit sandpapers (400, 600, 1000, 1200, and 2000), until the xylem cellular structure was visible in the transverse section. Wood dust inside vessel lumina was removed with heat by using a hair dryer [13]. The surface as not refilled with white chalk, since the wood was dark enough to increase the contrast of the vessels.…”

“…We used the historical drought years (characterized by a low wet season precipitation sum, higher temperatures, and longer dry season) recorded for Mexico (1929-1930, 1940, 1963, 1970, 1972, 1976, 1983, 1991, 1999, 2012, 2015-2016, and 2018-2019) obtained from the Mexican Drought Atlas (http://drought.memphis.edu/MXDA/Default.aspx; [45]). This allowed the recognition of narrow tree rings (≤1.00 mm) in the digital images of wood cores developed before, during, and after a drought event [13].…”

The Mexican tropical montane cloud forest trees occur under special and limited climatic conditions; many of these species are particularly more sensitive to drought stress. Hydric transport in leaf veins and wood features are influenced by climatic variations and individual intrinsic factors, which are essential processes influencing xylogenesis. We assessed the plastic response to climatic oscillation in two relict-endangered Magnolia schiedeana Schltdl. populations and associated the architecture of leaf vein traits with microenvironmental factors and wood anatomy features with climatic variables. The microenvironmental factors differed significantly between the two Magnolia populations and significantly influenced variation in M. schiedeana leaf venation traits. The independent chronologies developed for the two study forests were dated back 171–190 years. The climate-growth analysis showed that M. schiedeana growth is strongly related to summer conditions and growth responses to Tmax, Tmin, and precipitation. Our study highlights the use of dendroecological tools to detect drought effects. This association also describes modifications in vessel traits recorded before, during, and after drought events. In conclusion, our results advance our understanding of the leaf vein traits and wood anatomy plasticity in response to microenvironmental fluctuations and climate in the tropical montane cloud forest.

“…Strong vessel plasticity from M. schiedeana, given drought events ( Figure 4), enhances the statement of its need for specific microclimatic. Rodríguez-Ramírez et al [32] found that Mexican beech trees develop similar vessel trait adjustments, which may indicate that this forest type may be very sensitive to drought and thus susceptible to climate change [17,63,64]. On the other hand, M. vovidesii appears to show resilience to climatic variations such as strong DY, this is seen as a response to climatic variations such as strong DY (Figure 4).…”

“…The relationship between vessel traits and drought events ( Figure 4) reflects that both Magnolia species are capable to effectively allocate carbon during high hydric stress. These anatomical adjustments can allow Mexican trees of diverse functional types to continue growth during Fall, even if they are evergreen, semi-deciduous or deciduous trees [22,32,61,65,66].…”

The distribution of Mexican Magnolia species´ occur under restricted climatic conditions. As many other tree species from the tropical montane cloud forests (TMCF), Magnolia species appear to be sensitive to drought. Through the use of dendrochronological techniques, this study aims to determine the climate influence on the vessel traits of M. vovidesii and M. schiedeana which are endangered tree species that are endemic to the Sierra Madre Oriental in eastern Mexico. Because most of the tree species in TMCFs are sensitive to climate fluctuations, it is necessary to investigate the differences in the climatic adaptability of the vessel architecture of these trees. This could allow us to further understand the potential peril of climate change on TMCFs. We compared vessel frequency, length and diameter in drought and non–drought years in two Mexican Magnolia species. We used tree–rings width and vessel traits to assess the drought effects on Magnolias’ diffuse–porous wood back to the year 1929. We obtained independent chronologies for M. vovidesii with a span of 75 years (1941–2016), while for M. schiedeana we obtained a span of 319 years (1697–2016). We found that temperature and precipitation are strongly associated with differences in tree–ring width (TRW) between drought and non–drought years. Our results showed anatomical differences in vessel trait response between these two Magnolia species to climatic variation. We suggest that our approach of combining dendroclimatic and anatomical techniques is a powerful tool to analyse anatomic wood plasticity to climatic variation in Magnolia species.
