Influence of particulate matter air quality on water quality of atmospheric water harvesting Open
Atmospheric water harvesting (AWH) is a decentralized water technology that dehumidifies air to provide water. When atmospheric water is condensed, other atmospheric particles and gases can enter the liquid water. For AWH to serve as drink…

Non-destructive monitoring of tissue-specific, irrigation responsive impedance signals in leaves using microneedles probes Open
A non-destructive methodology for monitoring impedance changes in sorghum leaves was developed and recorded irrigation-dependent responses that differed between leaf tissues. Metal microneedles were used as impedance probes and were shown …

Microneedle-based electrical impedance sensor to monitor plant water status in real time Open
A sensor uses microneedle electrodes and multi-frequency electrical impedance spectroscopy to monitor plant water status in real time. The microneedle can be between 10 and 1000 microns in length, enabling precise placement in a variety of…

Principles of resilient coding for plant ecophysiologists Open
Plant ecophysiology is founded on a rich body of physical and chemical theory, but it is challenging to connect theory with data in unambiguous, analytically rigorous and reproducible ways. Custom scripts written in computer programming la…

Embolism recovery strategies and nocturnal water loss across species influenced by biogeographic origin Open
Drought‐induced tree mortality is expected to increase in future climates with the potential for significant consequences to global carbon, water, and energy cycles. Xylem embolism can accumulate to lethal levels during drought, but specie…

Abstract Drought-induced tree mortality is expected to increase in future climates with the potential for significant consequences to global carbon, water and energy cycles. Xylem embolism can accumulate to lethal levels during drought, bu…

Novel methods for measuring drought stress of crops in the field Open
There is currently no available method for land managers to directly and non-destructively measure the water status of plants in the field. Water status of a plant effects plant growth and function and contributes to end-of-season crop yie…

Is desiccation tolerance and avoidance reflected in xylem and phloem anatomy of two coexisting arid‐zone coniferous trees? Open
Plants close their stomata during drought to avoid excessive water loss, but species differ in respect to the drought severity at which stomata close. The stomatal closure point is related to xylem anatomy and vulnerability to embolism, bu…

Xylem embolism refilling and resilience against drought‐induced mortality in woody plants: processes and trade‐offs Open
Understanding which species are able to recover from drought, under what conditions, and the mechanistic processes involved, will facilitate predictions of plant mortality in response to global change. In response to drought, some species …

Impacts of long‐term precipitation manipulation on hydraulic architecture and xylem anatomy of piñon and juniper in Southwest USA Open
Hydraulic architecture imposes a fundamental control on water transport, underpinning plant productivity, and survival. The extent to which hydraulic architecture of mature trees acclimates to chronic drought is poorly understood, limiting…

Tree water dynamics in a drying and warming world Open
Disentangling the relative impacts of precipitation reduction and vapour pressure deficit ( VPD ) on plant water dynamics and determining whether acclimation may influence these patterns in the future is an important challenge. Here, we re…

Impacts of long-term precipitation manipulation on hydraulic architecture, xylem function, and canopy status in a piñon-juniper woodland Open
The Southwestern US is predicted to become hotter and drier, as global climate change forces increasing temperatures and variability in timing and size of precipitation inputs. Drought stress has become more frequent in recent decades, and…

Responses of two semiarid conifer tree species to reduced precipitation and warming reveal new perspectives for stomatal regulation Open
Relatively anisohydric species are predicted to be more predisposed to hydraulic failure than relatively isohydric species, as they operate with narrower hydraulic safety margins. We subjected co‐occurring anisohydric J uniperus monosperma…

Prolonged experimental drought reduces plant hydraulic conductance and transpiration and increases mortality in a piñon–juniper woodland Open
Plant hydraulic conductance ( k s ) is a critical control on whole‐plant water use and carbon uptake and, during drought, influences whether plants survive or die. To assess long‐term physiological and hydraulic responses of mature trees t…
