Diversity in Resource Use Strategies Promotes Productivity in Young Planted Tree Species MixturesNARA Subscribed
Mixed‐species forestry is a promising approach to enhance productivity, increase carbon sequestration, and mitigate climate change. Diverse forests, composed of species with varying structures and functional trait profiles, may have higher functional and structural diversity, which are attributes relevant to a number of mechanisms that can influence productivity. However, it remains unclear whether the context‐dependent roles...
Multiyear Drought Strengthens Positive and Negative Functional Diversity Effects on Tree Growth ResponseNARA Subscribed
Mixed‐species forests are proposed to enhance tree resistance and resilience to drought. However, growing evidence shows that tree species richness does not consistently improve tree growth responses to drought. The underlying mechanisms remain uncertain, especially under unprecedented multiyear droughts. We used a network of planted tree diversity experiments to investigate how neighborhood tree diversity and species' functio...
Forests and woodlands are the major source of wild medicinal plants worldwide. In our study, we aimed to identify the factors influencing the yield and polyphenol content of Aegopodium podagraria L., Galium aparine L., Rubus fruticosus L., Rubus idaeus L., Stachys sylvatica L. and Urtica dioica L., the common and abundant medicinal plant species in the study areas. We showed that European temperate forests are potentially an i...
Tree drought–mortality risk depends more on intrinsic species resistance than on stand species diversityNARA Subscribed
Increasing tree diversity is considered a key management option to adapt forests to climate change. However, the effect of species diversity on a forest's ability to cope with extreme drought remains elusive. In this study, we assessed drought tolerance (xylem vulnerability to cavitation) and water stress (water potential), and combined them into a metric of drought–mortality risk (hydraulic safety margin) during extreme 2021...
Thermal limits of survival and reproduction depend on stress duration: A case study of Drosophila suzukiiNARA Subscribed
Studies of ectotherm responses to heat extremes often rely on assessing absolute critical limits for heat coma or death (CT max ), however, such single parameter metrics ignore the importance of stress exposure duration. Furthermore, population persistence may be affected at temperatures considerably below CT max through decreased reproductive output. Here we investigate the relationship between tolerance duration and severity...
Lions and brown bears colonized North America in multiple synchronous waves of dispersal across the Bering Land BridgeNARA Subscribed
The Bering Land Bridge connecting North America and Eurasia was periodically exposed and inundated by oscillating sea levels during the Pleistocene glacial cycles. This land connection allowed the intermittent dispersal of animals, including humans, between Western Beringia (far northeast Asia) and Eastern Beringia (northwest North America), changing the faunal community composition of both continents. The Pleistocene glacial...
Current climate change aggravates human health hazards posed by heat stress. Forests can locally mitigate this by acting as strong thermal buffers, yet potential mediation by forest ecological characteristics remains underexplored. We report over 14 months of hourly microclimate data from 131 forest plots across four European countries and compare these to open‐field controls using physiologically equivalent temperature (PET)...
