TESTING OF CONSTRUCTION MATERIALS FOR CAVITATION RESISTANCE

The article presents the results of experimental studies of the cavitation erosion of structural materials widely used in aviation hydraulic drives. The effect of the air saturation of the working fluid on the intensity of the cavitation erosion of structural materials was determined.

Functional traits explain growth response to successive hotter droughts across a wide set of common and future tree species in Europe

Plant Biology, EarlyView.
Functional traits can explain significant tree growth reductions in response to the 2018–2020 drought for a wide set of 71 species including angiosperms and gymnosperms. Moreover, four distinct response types emerged: ‘Sufferer’, ‘Late sufferer’, ‘Recoverer’ and ‘Resister’, with gymnosperms predominately appearing as ‘Sufferer’ and ‘Late sufferer ...

Positive mixture effects in pine–oak forests during drought are context‐dependent

Plant Biology, EarlyView.
Mixture effects in drought‐stressed pine‐oak forests are context‐dependent, with Gambel oak and ponderosa pine benefiting from their complementarity under semi‐arid conditions. Abstract The increasing severity and frequency of droughts will play a pivotal role in shaping future forest ecosystems worldwide.

Recurrent hot droughts cause persistent legacy effects in a temperate Scots Pine forest

Plant Biology, EarlyView.
A series of hot drought events caused persistent legacy effects in a Scots Pine forest, with severe negative impacts on ecosystem carbon fluxes. Abstract Recent hot‐dry events have caused significant impacts and legacy effects in temperate ecosystems. Here, we investigate legacy effects of the 2018 hot drought on a Pinus sylvestris L.

Impact of emerging compound droughts on forests: A water supply and demand perspective

Plant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...
