Extreme drought events reduce the productivity of forest ecosystems. One approach for estimating effects on forests is by assessing their resilience. The objective this study was to estimate resilience rates at different heights along tree stem Pinus durangensis Martínez. radial growth 200 cross sections extracted four stems (0.07–0.15, 1.3, 6.3, and 11.0–12.0 m) analyzed subsequently transformed into ring-width indices (RWI). These were correlated with Standardized Precipitation-Evapotranspiration Index a six-month time scale (accumulated six months in period February–May; SPEI06FM). Seven extreme identified (1890, 1902, 1956, 1974, 1999, 2006, 2011), before, during, after each event determined. Based index values, resistance, recovery, calculated. results indicated significant correlation (p ≤ 0.05) between annual increment climate (0.56 0.80). Climatic sensitivity higher lower part stem, mean (MS) expressed population signal (EPS) values 0.38 0.97, respectively. Resistance ranged from 0.44 0.76 better stem. Resilience changed over time. Regardless height latest (1999, 2011) have led trees, indicating that recovery capacity has decreased. Therefore, forestry practices area may consider managing density as strategy regulate stress competition increase tolerance trees drought.

The Qinghai-Tibetan Plateau (QTP) is a global center of cold and dry, where the most extensive fragile alpine vegetation exists. Quantitative analysis drought event characteristics response to on QTP indispensable for understanding increasing events in warming climate which exacerbate adverse influence extremely ecosystems. Here, using standardized precipitation evapotranspiration index (SPEI) normalized difference (NDVI) from 2000 2018, this study analyzed events, their temporal impacts, stability QTP. Results showed that: have clear spatial heterogeneity. When compared east monsoon region, western regions higher frequency lower intensity events. Drought has significant effects grassland areas during growing season, reach peak July August. 0–1-month 3-month time scales were optimal lagged accumulated respectively. heterogeneity varied with eco-geographical types. Generally, forest high resistance (74.09) resilience (2.26), followed by crop areas.

Recently, forests in the Tianshan Mountains have shown a marked decline growth and an increased mortality rate because of more frequent severe effects extreme drought, which threatens ecosystem services they provide. To achieve forest conservation sustainable development benefits, it is crucial to understand post-drought recovery trajectory tree its driving factors. In this study, we quantified performance dominant species after drought events determined influences climate factors on resilience using tree-ring proxy data. The results showed that moisture conditions may determine trees. for 1997 was higher than 1974, be attributed subsequent period experiencing very high precipitation, whereas year following 1974 dry (Standardized Precipitation Evapotranspiration Index < 0). Because favorable period, observed relationship between resistance closer fit hypothetical "line full resilience" sets constant value 1, allowing trees recover fully at any given resistance. Trees lower mean values index (RC) average (ARR) total reduction (TGR) (RE) event 1997. We distinguished relative influence temperature precipitation different phases Boosted Regression Tree (BRT) model. during variation were most influential variables recovery. Specifically, explained up 20 % variance RC, TGR, RE, ARR. These findings deepen our understanding impacts prolonged growth, could aid developing management strategies respond drought.

The constant rise in the global temperature and unpredictable shifts precipitation patterns are two of main effects climate change. Therefore, there is an increasing amount interest identification tree species, provenances genotypes capable withstanding more arid conditions tolerating drought stress. In present review, we focus our attention on generally susceptible conifers describe different strategies that plants adopt to respond We approaches taken studies conifer adaptations low water availability, advantages limitations each, results obtained with each these recent years. Then discuss how morphological, physiological genetic data may find practical applications forest management, particular next-generation breeding programs. Finally, provide some recommendations for future research. particular, suggest extending a broader selection species genera, number adult plants, those gene expression, distinguishing between types stress can withstand during its life cycle. integration coming from disciplines will be key factor knowledge about trait as complex resistance.

More frequent and severe droughts have affected forest ecosystems throughout Europe in recent decades. In Central Europe, large-scale dieback of Norway spruce has, for example, been observed, whereas decline was so far less widespread Eastern Europe. To assess the potential future impacts drought on southeastern part its natural distribution, studies resilience are urgently needed. Here, we use a tree-ring network consisting more than 3000 trees from 158 managed stands different ages distributed along elevational gradients Carpathians to growth responses drought. Specifically, analyzed differences components (e.g., resistance, recovery, resilience, recovery period) with elevation tree age, used 'line full resilience' concept comprehensively resilience. Our results show that at low elevations (<800 m) is characterized by lowest resistance drought, though has high while (>1400 m), higher associated recovery. general, older were found need time recover. Resilience decreases water deficit, suggesting risk ongoing climate change, urging adaptative management. • Spruce assessed using Carpathians. suffers most elevations, it recovers quickly. Older risk.
