<p>Earth’s forests face grave challenges in the Anthropocene, including hotter droughts increasingly associated with widespread forest die-off. But despite the vital importance of forests—especially historical forests—to global ecosystem services, their fates in a warming world remain highly uncertain. Critically missing is quantitative determination of hotter-drought climatic drivers at globally-distributed, ground-based, tree-mortality sites. We established a precisely geo-referenced global database documenting climate-induced mortality events spanning all tree-supporting biomes from 154 studies since 1970. Here we quantify a lethal global hotter-drought fingerprint from these tree-mortality sites across 675 locations encompassing 1,303 database plots. Frequency of these lethal climate conditions accelerates under projected warming, up 140% by +4℃. Our database, soon available at tree-mortality.net, provides initial footing for further community development of quantitative, ground-based monitoring of global tree mortality (e.g., still including peer-reviewed observations, but importantly also those from forestry professionals, land managers, and citizen scientists). Furthermore, our database immediately enables critical predictive model validation and improved remote sensing of mortality. While our initial database enabled empirical quantification of a global climate signal for hotter-drought triggered tree mortality, ongoing and online contributions to the database (with efforts to be more spatially representative) will enable myriad future analyses and progress toward understanding the role of hotter-drought in the mechanistically complex process of tree mortality. Our global fingerprint of lethal hotter-drought confirms many of Earth’s forests are increasingly imperiled by further warming.</p>

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

The aim of this study was to examine the influence of climate conditions and ripening on total phenols (TP), total monomeric anthocyanins (TAC) and antioxidant capacity (AC) of Maraska and Oblačinska sour cherries. For that reason, TP using Folin-Ciocalteau reagent, TAC by pH-differential method and AC via DPPH method were determined in Maraska and Oblačinska sour cherry samples harvested in Zadar and Osijek area in 2014 at three maturity stages. Despite that statistical analysis showed significant differences in TP and AC between cultivars and growing locations, obtained results revealed considerable functional properties of both cultivars. Still, Maraska achieved higher TP, TAC and AC values compared to Oblačinska. Furthermore, Mediterranean climate conditions positively affected on bioactive compounds accumulation in both cultivars, where generally the highest contents of examined bioactive compounds were accomplished at the latest harvest date.

Trunk Diameter Fluctuations

The present research aimed to evaluate the water dynamics of grapevines trained in Cordon and Guyot systems by coupling sap flow and trunk diameter measurements under Mediterranean climate conditions. The study was conducted in a vineyard with Touriga-Nacional located at the Douro Valley, Portugal, during 2017. The results showed daily trunk diameter fluctuations (TDFs), with the contraction, recovery and increment phases and higher sap flow (SF) rates at earlier stages. Under harsh pedoclimatic conditions, SF was reduced and TDF flattened. Rehydration and stomatal mechanisms were mostly associated with these responses. Guyot vines showed higher changes in TDF for the same SF values, whereas the TDFs of Cordon vines remained practically unchanged over maturation. Guyot vines generally showed increased values of cumulative increment and maximum daily trunk shrinkage. Although Guyot vines had a similar leaf area index (LAI), they showed higher SF/LAI ratios than Cordon vines. These results highlight the effect of the shorter length of the hydraulic pathways of the Guyot training system, in contrast to the higher trunk and the permanent horizontal branch (cordon) of the Cordon training system, indicating good adaptation to local pedoclimatic conditions. The study pointed to the complementary use of both techniques in the evaluation of grapevine water dynamics.
