Growth and resilience responses of Scots pine to extreme droughts across Europe depend on predrought growth conditions

Abstract: Global climate change is expected to further raise the frequency and severity of extreme events, such as droughts. The effects of extreme droughts on trees are difficult to disentangle given the inherent complexity of drought events (frequency, severity, duration, and timing during the growing season). Besides, drought effects might be modulated by trees’ phenotypic variability, which is, in turn, affected by long‐term local selective pressures and management legacies. Here we investigated the magnitude and th… Show more

“…Our results support our hypothesis that drought sensitivity varies among trees at different altitudes and among age groups, indicating that trees display different strategies among these categories to withstand the effects of drought (Bose et al, 2020). The results further support previous conclusions that the ecological resilience of trees to extreme drought varies along climatic gradients and the spatial heterogeneity of habitats (Gazol et al, 2016;Sánchez-Salguero et al, 2018).…”

“…7) showed that the Rt, Rc, and Rs of P. yunnanensis features a regular variation with drought frequency and conditions rather than remaining unchanged. This pattern suggests the increased frequency of drought would weaken the resistance and recovery of trees, the vulnerability of trees to drought increased after the successive drought episodes (Serra-Maluquer et al, 2018; Bose et al, 2020). Subsequent droughts generally have a more deleterious impact than initial droughts, the increased drought frequency and duration could result in "cumulative effects" and persistent physiological damage, and further decrease tree resilience to subsequent droughts (Hacke et al, 2001;Sala et al, 2012).…”

“…Further, we documented an increased role of moisture availability on Scots pine growth in the second interval which was particularly important for most of the sites (dune ridge and bottom) located in the southern sub-region ( Supplementary Figure S4). Our findings might indicate that in general warmer and drier winter-spring/summer seasons (von Storch et al, 2015) cause more drought stress for trees at the coastal sand dune sites, however, this drought stress is not equal across the tree-ring network due to a multitude location-specific site-, tree-, and drought related factors as well as their interactions (Bose et al, 2020).…”

“…In the central part of the species distribution in Europe, i.e., in a transition zone from boreal to temperate forests and toward the south of its distributional range, winter or winter-spring temperatures mainly and positively influence Scots pine growth (RW: Pärn, 2002;Hordo et al, 2011;Balanzategui et al, 2018;Metslaid et al, 2018;Matisons et al, 2019;Harvey et al, 2020;EBI: Seftigen et al, 2020). In addition to temperature, moisture availability has also been documented as a growth-limiting factor (RW: Helama and Lindholm, 2003;Vitas, 2004Vitas, , 2006Erlickytė and Vitas, 2008;Drobyshev et al, 2011;Düthorn et al, 2013;Bose et al, 2020;RW and EBI: Seftigen et al, 2020). At the southern distribution margin, plant water availability (RW: Bogino et al, 2009;Buras et al, 2018a), precipitation (RW: Sánchez-Salguero et al, 2015a), and winter, spring, or summer temperatures (RW: Herrero et al, 2013;Sánchez-Salguero et al, 2015a,b) modulate Scots pine growth.…”

“…There is evidence that climate change increases drought impacts on tree growth and vitality, e.g., [12][13][14], and concomitant damages, such as insect attacks [15,16] or wildfires [17]. Due to climate change, forest planners are challenged by a precarious future.…”
