英文摘要	The relevance of forests in mitigating biodiversity loss and the negative effects of climate change on the biota is largely shaped by below -canopy microclimatic conditions, which are buffered, cooler and more humid compared to adjoining open habitats. Water -filled tree holes (dendrotelms, DTs) are special tree -related microhabitats that host semi -aquatic communities and are important substrates or water sources for numerous taxa (e.g., birds, mammals, insects, fungi, bryophytes). Despite their microrefugia-role might be more pronounced under climate change -induced drought events, little is known about their microclimate and its potential drivers. In an abandoned Turkey oak -dominated coppice stand in Hungary, the microclimates of 80 paired dendrotelms and adjacent forest plots were measured in the summer of 2021. Compared to nearby open areas, under closed forests, air temperature maxima were up to 5 degrees C cooler, DTs had an additional negative offset of 2.5 degrees C and increased air humidity by 15 percentage points (5% vs. 20 %). The local microclimate of DTs and the adjacent closed forest differed significantly in means and extremes of air temperature, relative humidity and vapour pressure deficit, which was mainly driven by DT entrance area and water volume and seemed independent from local stand structure. On the contrary, nearby below -canopy microclimate was shaped by the distance from forest edge, incoming light and tree density. Water volume in DTs also influenced local forest microclimates up to 0.5-1 m from the entrances. As the frequency and severity of extreme weather events such as heatwaves are likely to intensify due to climate change, the importance of microhabitats and habitat trees for invertebrates and vertebrates will increase further, and will additionally contribute to the microclimatic refugia role of forests. Active protection of veteran trees under the scheme of continuous cover forestry or conservation -oriented management is essential facing climate change to mitigate its negative effects on forest biodiversity.
