Hybrid Douglas-fir trees, with mixed ancestry from coastal and interior varieties, may offer greater resilience to climate change due to their higher water use efficiency and heat tolerance, making them a better choice...

Fast and small stomata optimise the water use efficiency of sugar beet
Can a better understanding of stomatal physiology make sugar beet more productive and resilient into the future?

δ13Cp as proxy for water use efficiency is deceptive in young leaves
During leaf expansion, the measurement gives counterintuitive results.

Short- and long-term responses to elevated carbon dioxide use the same genetic controls
Manipulating stomatal traits could produce more crops for dry regions.
Abscisic acid receptors in Populus canescens aid water use
Botanists show how abscisic acid receptors in poplar can ease drought stress.

Evolution of mating system, life history, and photosynthetic physiology in Clarkia
In the western United States, Clarkia (Onagraceae) taxa vary in mating system, life history, and photosynthetic physiology. Self-fertilizing taxa bloom earlier in the year and have higher rates of photosynthesis than...

Interactive effects of [CO2] and water availability on maritime pine
Evidence from this study indicates that elevated [CO2] not only can aggravate the effects of water deficit on photosynthetic performance and growth of maritime pine but also it can attenuate genotypic differences in...
Antarctic endophytes improve drought tolerance in lettuce plants
Climate change has limited the availability of water for irrigating crops throughout many regions of the world. Indeed, current models of climate change predict that arid and semi-arid zones will be places where...

Becoming a better locksmith: a new method speeds up our ability to unlock secrets of past climates
Chemical isotopes in tree rings can help us learn about past environments, but how can you extract them without interfering with measurements?

Tropical conifer response to altered CO2 concentration
Conifers dominated the lowland tropics 100 million years ago, but have now been largely replaced by angiosperms, coincident with a large decline in atmospheric CO2. Using greenhouse treatments of pre-industrial...
Does greater specific-leaf-area plasticity help plants to maintain a high performance when shaded?
Both phenotypic plasticity and local adaptation may allow widely distributed plant species to either acclimate or adapt to environmental heterogeneity. Given the typically low genetic variation of clonal plants across...
Water stress acclimation in xeric but not riparian Eucalyptus
Experimental drought is well documented to induce a decline in photosynthetic capacity. However, if given time to acclimate to low water availability, the photosynthetic responses of plants to low soil moisture content...
Phosphorus and elevated CO2 enhance drought tolerance
Benefits to crop productivity arising from increasing CO2 fertilization may be offset by detrimental effects of global climate change, such as an increasing frequency of drought. Phosphorus ( P ) nutrition plays an...
Host tree phenology affects vascular epiphytes at the physiological, demographic and community level
The processes that govern diverse tropical plant communities have rarely been studied in life-forms other than trees. Structurally dependent vascular epiphytes, a major part of tropical biodiversity, grow in a three...
