Seasonal drivers of understorey temperature buffering in temperate deciduous forests across Europe

Aim: Forest understory microclimates are often buffered against extreme heat or cold, with important implications for the organisms living in these environments. We quantified seasonal effects of understory microclimate predictors describing canopy structure, canopy composition and topography (i.e. local factors), as well as forest patch size and distance to coast (i.e. landscape factors). Location: Temperate forests in Europe Time period: 2017-2018 Major taxa studied: Woody plants Methods: We combined data from a microclimate sensor network with weather station records to calculate the difference – or offset – between temperatures measured inside and outside forests. We used regression analysis to study the effects of local and landscape factors on the seasonal offset of minimum, mean and maximum temperatures. Results: Maximum temperature during summer was on average cooler by 2.1 °C and minimum temperature during winter and spring were 0.4 °C and 0.9 °C warmer inside than...研究目标：森林林下微气候通常可缓冲极端高温与低温，对栖息于此的生物具有重要意义。本研究量化了林下微气候影响因子的季节效应，涵盖冠层结构、冠层组成与地形（局地因子），以及森林斑块面积、距海岸距离（景观因子）。 研究区域：欧洲温带森林 研究时段：2017-2018年 研究类群：木本植物 研究方法：本研究将微气候传感器网络数据与气象站观测记录相结合，计算林内与林外气温的差值（即气温偏移量）。通过回归分析，探究局地与景观因子对最低、平均及最高气温季节偏移量的影响。 研究结果：夏季林内最高气温平均较林外低2.1℃，冬季与春季林内最低气温分别较林外高0.4℃与0.9℃，且...
