Photosynthetic temperature responses in leaves and canopies: why temperature optima may disagree at different scales Open
Understanding how canopy-scale photosynthesis responds to temperature is of paramount importance for realistic prediction of the likely impact of climate change on forest growth. The effects of temperature on leaf-scale photosynthesis have…

Isotopic steady state or non-steady state transpiration? Insights from whole-tree chambers Open
Unravelling the complexities of transpiration can be assisted by understanding the oxygen isotope composition of transpired water vapour (δE). It is often assumed that δE is at steady state, thereby mirroring the oxygen isotope composition…

Reconciling Top‐Down and Bottom‐Up Estimates of Ecosystem Respiration in a Mature Eucalypt Forest Open
Ecosystem respiration (R eco ) arises from interacting autotrophic and heterotrophic processes constrained by distinct drivers. Here, we evaluated up‐scaling of observed components of R eco in a mature eucalypt forest in southeast Australi…

Progress in forecasting carbon, water and energy fluxes in improved and degraded pastures: data-model comparison near Sydney Australia  Open
Livestock grazing contributes to greenhouse gas (GHG) emissions, soil degradation and erosion, and loss of biodiversity. Regenerative pasture management includes improvements such as sowing high-diversity seed mixtures with legumes and oth…

Elevated atmospheric <span>CO<sub>2</sub></span> suppresses silicon accumulation and exacerbates endophyte reductions in plant phosphorus Open
Many temperate grasses are both hyper‐accumulators of silicon (Si) and hosts of Epichloë fungal endophytes, functional traits which may alleviate environmental stresses such as herbivore attack. Si accumulation and endophyte infection may …

Similar patterns of leaf temperatures and thermal acclimation to warming in temperate and tropical tree canopies Open
As the global climate warms, a key question is how increased leaf temperatures will affect tree physiology and the coupling between leaf and air temperatures in forests. To explore the impact of increasing temperatures on plant performance…

Optimal stomatal theory predicts <span>CO<sub>2</sub></span> responses of stomatal conductance in both gymnosperm and angiosperm trees Open
Summary Optimal stomatal theory predicts that stomata operate to maximise photosynthesis ( A net ) and minimise transpirational water loss to achieve optimal intrinsic water‐use efficiency (iWUE). We tested whether this theory can predict …

Green-up and brown-down: Modelling grassland foliage phenology responses to soil moisture availability Open
Grassland responses to drought are strongly mediated by leaf phenology, with greening and browning being highly sensitive to soil moisture. However, this process is represented overly simplistically in most vegetation models, limiting thei…

Tapping into the physiological responses to mistletoe infection during heat and drought stress Open
Mistletoes are important co-contributors to tree mortality globally, particularly during droughts. In Australia, mistletoe distributions are expanding in temperate woodlands, while their hosts have experienced unprecedented heat and drough…

Radially transmitted changes in hydraulic and osmotic pressures help explain reversible and irreversible patterns of tree stem expansion Open
It is easy to measure annual growth of a tree stem. It is hard to measure its daily growth. The reason for this difficulty is the microscopic scale and the need to separate processes that simultaneously result in reversible and irreversibl…

Increasing aridity will not offset CO<sub>2</sub>fertilization in fast‐growing eucalypts with access to deep soil water Open
Rising atmospheric [CO 2 ] ( C a ) generally enhances tree growth if nutrients are not limiting. However, reduced water availability and elevated evaporative demand may offset such fertilization. Trees with access to deep soil water may be…

Whole‐tree mesophyll conductance reconciles isotopic and gas‐exchange estimates of water‐use efficiency Open
Summary Photosynthetic water‐use efficiency (WUE) describes the link between terrestrial carbon (C) and water cycles. Estimates of intrinsic WUE (iWUE) from gas exchange and C isotopic composition (δ 13 C) differ due to an internal conduct…
