Ecological drivers and phylogenetic patterns of leaf minimum conductance variability in vascular plants

New Phytologist, EarlyView.
Summary Stomatal closure prevents significant water losses during drought events. Yet, leaves are not perfectly hermetic and dehydration ensues through residual water losses, known as minimum conductance (gmin), which is highly relevant since it informs on the water depletion dynamics under stress.

A novel compact 4 x 4 Multi-slot MIMO antenna for N78/79, Wi-Fi 5/6, and V2X/DSRC for 5G in Sub-6 GHz band

Advanced Electromagnetics
In this article, a novel multi-slot 2-port and 4-port compact wideband MIMO antennas are designed for 5G communication in the sub-6 GHz band. The multi-slot antenna contains a rectangular patch with two square cuts at the lower corner of it.

Thermal Safety Margins and Peak Leaf Temperatures Predict Vulnerability of Diverse Plant Species to an Experimental Heatwave

Plant, Cell &Environment, EarlyView.
ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

Heat treatment duration affects in vitro‐induced photosynthetic impairment and development of necrotic leaf tissue in three Mediterranean oak species

Plant Biology, EarlyView.
Longer lasting heat treatment durations induced photosynthetic impairment at lower temperatures and caused the development of proportionally more necrotic tissue at lower temperatures in leaves of three Mediterranean oak species. Abstract Short heat treatments are commonly used to estimate the leaf‐level thermal tolerance of tree species. The effect of

On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

Plant Biology, EarlyView.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

The oral microbiota and periodontal health in orthodontic patients

Periodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
