Attributing the temperature response of tree seedling growth to underlying mechanisms Open
Studies of plant responses to temperature often focus on rates photosynthesis and respiration. However, within-plant utilisation and allocation of carbon are also strongly affected. It is unclear how much each of these processes contribute…

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…

The temperature optima for pollen germination and pollen tube growth of coconut (<i>Cocos nucifera</i> L.) strongly depend on the growth temperature Open
Understanding trait variation in response to temperature is important to predict how crops respond to rising temperature. Although we have a sound understanding of the effects of increasing temperature on growth and development of crops, a…

Impact of Mild Water Stress During the Flowering Stage on Leaf Functional Traits and Yield of Selected Cowpea Varieties Grown in The Low Country Dry Zone of Sri Lanka Open
Cowpea [Vigna unguiculata (L.) Walp.] is an important legume growing in tropical regions. Cowpea is grown in the Dry Zone of Sri Lanka as an inter-season crop. Rising temperatures and unpredictable precipitation patterns are major factors …

Acclimation of Ecophysiological and Agronomic Traits to Increasing Growth Temperature in Three Cowpea Genotypes Grown in Anuradhapura, Sri Lanka Open
The future of food crop production is uncertain due to the negative effects of global warming. Cowpea is grown in warm environments including in Sri Lanka, where less is known about the potential acclimation of ecophysiological and agronom…

Effect of Water Stress during Seed Production and Storage Time on Germination and Seedling Growth of Cowpea Grown in the Dry Zone of Sri Lanka Open
The water stress during the flowering stage of cowpea reduces the seed yield of the same season, but its effect on seed germination and seedling growth in the following season remains poorly understood. This study was carried out to determ…

Triose phosphate utilization limitation: an unnecessary complexity in terrestrial biosphere model representation of photosynthesis Open
Triose phosphates are the principal product of photosynthesis. They are used within the chloroplast for starch synthesis, or translocated to the cytosol where they are used to fuel sucrose synthesis. Use of triose phosphate releases inorga…

Low sensitivity of gross primary production to elevated CO <sub>2</sub> in a mature eucalypt woodland Open
The response of mature forest ecosystems to a rising atmospheric carbon dioxide concentration (Ca) is a major uncertainty in projecting the future trajectory of the Earth's climate. Although leaf-level net photosynthesis is typically stimu…

No evidence for triose phosphate limitation of light‐saturated leaf photosynthesis under current atmospheric CO<sub>2</sub> concentration Open
The triose phosphate utilization ( TPU ) rate has been identified as one of the processes that can limit terrestrial plant photosynthesis. However, we lack a robust quantitative assessment of TPU limitation of photosynthesis at the global …

Acclimation and adaptation components of the temperature dependence of plant photosynthesis at the global scale Open
Summary The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models ( GVM s). The response may vary geographically, owing to genetic adaptation to climate, and…

Trees tolerate an extreme heatwave via sustained transpirational cooling and increased leaf thermal tolerance Open
Heatwaves are likely to increase in frequency and intensity with climate change, which may impair tree function and forest C uptake. However, we have little information regarding the impact of extreme heatwaves on the physiological perform…
