摘要
随着气候变化的加剧,树木面临更高的干旱风险,从而影响未来的森林构成。本研究比较了黑松(Pinus nigra)在其南北分布范围内对气候的敏感性和恢复力,为在不断变化的环境条件下进行适应性森林管理提供指导。研究分析了黑松北部分布区(斯洛文尼亚)七个地点和南部分布区(土耳其西部)三个不同地点的 211 棵黑松的树环核心,包括黑松亚种和黑松亚种 pallasiana。我们研究了气候-生长动态,评估了温度和降水与树环宽度指数的相关性,并分析了恢复力指数。利用遥感数据评估了地表反射率和光合作用活动的差异。我们的研究结果揭示了南部和北部黑叶楠木种群之间不同的气候-生长模式,降水主要影响南部的生长,而降水和温度都影响北部的生长。考虑到每个种群的具体地点条件,恢复力指数进一步表明,P. nigra subsp.由于降水的限制,北部地区的地点表现出最低的抗性。受温度限制的地点表现出最高的抗逆性,表明干旱对树木生长的潜在长期影响。我们的发现加深了我们对南欧两个黑松亚群的气候-生长反应和恢复机制的了解。
Distinct spatial patterns in climate-growth relationships, vegetation and resilience indices of Black pine (Pinus nigra J.F. Arnold) from its northern and southern distribution range
As climate change intensifies, trees face heightened drought risks, impacting future forest composition. This study compares the climate sensitivity and resilience of black pine (Pinus nigra) across its north-south distribution range, guiding adaptive forest management amidst changing environmental conditions. Tree-ring cores from 211 P. nigra trees across seven sites in northern distribution (Slovenia) and three different sites in southern distribution range (Western Turkey), including the subspecies P. nigra subsp. nigra and P. nigra subsp. pallasiana, were analyzed. We investigated climate-growth dynamics, evaluating temperature and precipitation correlations with tree-ring width indices, and analyzed resilience indices. Leveraging remote sensing data, disparities in surface reflectance and photosynthetic activity were assessed. Our findings reveal distinct climate-growth patterns between southern and northern P. nigra populations, with precipitation predominantly shaping growth in the south and both precipitation and temperature influencing growth in the north. Given the site-specific conditions of each population, resilience indices further suggest that P. nigra subsp. pallasiana exhibits stronger drought tolerance. Sites in the northern range show the lowest resistance due to precipitation limitation. Temperature-limited sites demonstrate the highest resilience, indicating potential long-term effects of drought on tree growth. Our findings enhance our understanding of the climate-growth responses and resilience mechanisms in two subpopulations of Pinus nigra in Southern Europe.
