Rapid non‐destructive assessment of leaf water status with low‐cost transmittance meters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tools for more efficiently managing agricultural production and the use of limited water resources are required in the context of a growing global population, while the increasing threat posed by droughts and wildfires necessitates improved methods for risk assessment, forecasting and early warning. Quantifying leaf water content is central to

Stomatal density and length as genetic markers of coconut

open access: yes, 1984
Leaf samples of five green coconut varieties and their F1 hybrids were collected to determine stomatal density and size. The same parameters were determined in two color forms of San Ramon.

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Reactive oxygen species, antioxidants and the regulation of plant development

open access: yesThe FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

The Effect of Orthodontic Tooth Movement on Intrabony Periodontal Defects After Guided Tissue Regeneration. Part II: The Evaluation of Clinical and Radiological Parameters in a Randomised Controlled Clinical Trial

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To clinically and radiologically evaluate the healing capacity of intrabony periodontal defects treated with guided tissue regeneration (GTR) with or without the combination of orthodontic tooth movement (OTM). Materials and Methods Thirty‐four individuals presenting with periodontal intrabony defects (IDs) and pathological tooth migration
