The water potential at turgor loss point (Ψtlp ) has been suggested as a key functional trait for determining plant drought tolerance, because of its close relationship with stomatal closure. Ψtlp may indicate tolerance plants, which maintain gas exchange lower midday potentials soil availability declines also have . We evaluated 17 species from seasonally dry habitats, representing range life-forms, under well-watered and conditions, to determine how relates sensitivity (pre-dawn closure:...
Understanding which hydraulic traits are under genetic control and/or phenotypically plastic is essential in understanding how tree species will respond to rapid shifts climate. We quantified Eucalyptus obliqua L'Her. across a precipitation gradient the field describe (i) trait variation relation long-term climate and (ii) short-term (seasonal) ability of adjust (i.e., phenotypic plasticity). Seedlings from each population were raised controlled conditions assess (iii) strong control. In...
ABSTRACT Proteaceae are adapted to acquire P from nutrient‐impoverished soils; many function at very low leaf levels, but killed by fertilization. Phosphorus toxicity develops a remarkably external concentration. Previous studies have described in Proteaceae, the physiological basis for it remained unclear. The aim of present study was elucidate Hakea prostrata R. Br. (Proteaceae). Triticum aestivum L. (Gramineae), Medicago truncatula Gaertn., Lupinus albus (both Fabaceae) and R.Br. were...
Cities around the world are embracing stormwater control measures (SCMs) to reduce environmental damage caused by impervious runoff. At same time, there is a push increase tree canopy cover green neighborhoods and mitigate urban heat. Establishing SCMs that include trees may achieve these two objectives, but it important understand which design characteristics promote or health growth. We therefore undertook an 18-month streetscape experiment comparing four pit SCM designs, along with...
Directing stormwater runoff to irrigate urban trees has the potential simultaneously: (i) reduce volume of generated by impervious surfaces and (ii) tree drought stress increase growth. Many papers promote this concept, but few have quantified both benefits. In study, we retention performance infiltration trenches retrofitted alongside established street We compared for different soil types, phenological types inlet designs over a period 18 months. Retention was low on average (18.3%) highly...
Abstract Over their lifetime, trees are repeatedly exposed to droughts. It is therefore important understand whether repeated drought exposure makes more or less tolerant. Here, we investigated the effect of droughts on functional trait expression and tree function in Eucalyptus obliqua. Further, tested previous enabled avoid leaf death for longer under a subsequent severe drought. Trees were subjected 1 year 2 drought–rewatering cycles (drought treatment) well-watered conditions, before...
Many cities are developing ambitious future canopy cover targets in recognition of urban trees' numerous benefits. Selecting fast-growing and climate-adapted tree species is important to help achieve these targets. The assessment growth performance challenging, but essential for selecting that grow different environments. Often, remote sensing used measure change at a landscape or neighbourhood scale forests, rarely individual scales. In this study, we developed novel spatial analysis method...
Abstract Succulence describes the amount of water stored in cells or organs, regardless plant life-form, including woody and herbaceous plants. In dry environments, plants with greater survival often have leaf succulence. However, it is unclear how succulence relates to drought resistance strategies, isohydry (closing stomata maintain status) anisohydry (adjusting cell turgor tolerate low status), which exist on a continuum that can be quantified by hydroscape area (larger indicates more...
Green roofs can reduce stormwater runoff in urban areas by capturing rainfall. The extent of this capture is partially influenced vegetation type and cover, which be manipulated to optimise run-off reduction. However, the absence routine maintenance, planted green roof often replaced 'weedy' spontaneous species with unknown rainfall retention qualities. To better understand role mitigation, we undertook a 100-day simulation involving 14 plant that occur spontaneously on Mediterranean-type...
This study describes the physiological response of two co-occurring tree species (Eucalyptus marginata and Corymbia calophylla) to seasonal drought at low- high-quality restored bauxite mine sites in south-western Australia. Seasonal changes photosynthesis (A), stomatal conductance (g(s)), leaf water potential (ψ), osmotic relative content (RWC) pressure-volume analysis were captured over an 18-month field (i) determine nature severity stress relation site quality (ii) identify any...
Quantifying pollutant removal by stormwater wetlands requires intensive sampling which is cost-prohibitive for authorities responsible a large number of wetlands. Wetland managers require simple indicators that provide practical means estimating performance and prioritising maintenance works across their asset base. We therefore aimed to develop vegetation cover metrics derived from monitoring water level, as likely nutrient Over two-year period, we measured levels at 17 used both predict...
Abstract This research aimed to investigate coarse root systems of Jarrah ( Eucalyptus marginata Donn ex Sm.) trees at a 13‐year‐old restored bauxite mine site in south‐western Australia. Excavations an area with small (low‐quality site) revealed that deep ripping equipment failed penetrate the cemented lateritic subsoil, restricting roots (roots >5 mm diameter) top 0.5 m soil profile, resulting fewer (1,344 stems/ha) and smaller (mean height 4.5 m) trees. An adjacent within same pit...
