Betula ermanii range-wide provenance trial: Survival, height, diameter, and productivity data

Understanding the response of Betula ermanii populations to climate change is crucial for conservation efforts. Range-wide provenance trials provide valuable insights into local adaptation and phenotypic plasticity, aiding in the maintenance of productivity in boreal and alpine forest ecosystems. This study aimed to evaluate the impact of climate change on survival and productivity of B. ermanii, and to formulate conservation strategies for future climates. Using survival and growth data from provenance trials, models were developed and applied to projected climate scenarios obtained from WorldClim. Results indicated that populations at the southern edge and thermal limit experienced more pronounced declines in survival and productivity compared to others. Particularly, the southern-edge population struggled to survive in situ under severe climate warming, while the high-altitude edge population faced challenges in surviving ex situ. These findings emphasize the necessity of integrating..., Betula ermanii, a wind-pollinated deciduous tree species, is a significant component of Japan's deciduous broad-leaved forests, particularly prevalent in subalpine regions and forest margins, where it often forms pure forests. Seeds of B. ermanii were gathered during the autumns of 2016 and 2017 from 11 natural populations across its distribution zones. These seeds were grown in the nursery at the University of Tokyo Hokkaido Forest (UTHF) in April 2018. Following two growing seasons, containerized saplings were planted at 11 sites across Japan in autumn 2019 and spring 2020. Each planting site received 20 seedlings per population, with exceptions for Akkeshi (AKS), Goyo-San (GYS), and Choukai-San (CKS). This endeavor resulted in a total of 2013 seedlings (183 seedlings × 11 planting sites). Random planting designs were implemented for each site to mitigate spatial autocorrelation issues. Survival counts, height, and diameter measurements were conducted in autumn from 2020 to 2023.

理解岳桦（Betula ermanii）种群对气候变化的响应对于保护工作至关重要。全域种源试验为研究局部适应和表型可塑性提供了宝贵见解，有助于维持北方和高山森林生态系统的生产力。本研究旨在评估气候变化对岳桦（B. ermanii）存活与生产力的影响，并制定面向未来气候的保护策略。利用种源试验的存活与生长数据，研究人员构建模型并将其应用于从WorldClim获取的未来气候情景预测中。结果表明，与其他种群相比，分布在南缘和热极限区域的岳桦种群在存活和生产力方面出现了更为显著的下降。特别是南缘种群在剧烈气候变暖下难以原地存活，而高海拔边缘种群则面临异地存活的挑战。

岳桦（Betula ermanii）是一种风媒传粉的落叶树种，是日本落叶阔叶林的重要组成部分，尤其在亚高山区域和森林边缘广泛分布，并常形成纯林。2016年和2017年秋季，研究人员从岳桦（B. ermanii）分布区的11个自然种群中采集种子。这些种子于2018年4月在东京大学北海道森林（UTHF）苗圃中培育。经过两个生长季后，容器苗于2019年秋季和2020年春季在日本全国11个地点进行种植。每个种植点的每个种群种植20株幼苗，但厚岸（Akkeshi，AKS）、御岳山（Goyo-San，GYS）和鸟海山（Choukai-San，CKS）除外。此次种植共涉及2013株幼苗（183株幼苗×11个种植点）。每个种植点均采用随机种植设计，以缓解空间自相关问题。2020年至2023年秋季期间，研究人员对幼苗的存活数量、高度和直径进行了测量。
