Why did Gingko almost disappear during the TriassicโJurassic mass extinction when ferns did so well? The answer has relevance for future atmospheric changes.
Soil water availability is an important mechanism filtering plant species. Twenty-five herbaceous dicot species were grown under controlled conditions in order to measure a suite of physiological traits associated with...
Plants grow in a variable environment. While the effects of various environmental factors such as CO2 concentration, temperature, air humidity, and blue light on steady-state photosynthesis have been well documented...
Climate change is expected to bring warmer temperatures and more variable precipitation patterns worldwide, patterns that will depend on the ability of the worldโs flora to take up carbon under these new conditions. In...
Selected Eucalyptus globulus clones can grow to a height of up to 14m in 3 years, receiving an average rainfall of 630โmm yearโ1 with a 4-month summer drought. Working with plants under a year old from five clones...
Modern clubmosses (Lycophytes) are a vestige of their gargantuan carboniferous ancestors that dominated the paleoflora flora for millions of years. The group has a broad global distribution ranging from tundra to...
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...
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...
Stomatal closure can be caused by an increase in internal CO2 concentration resulting from ozone-induced inhibition of carbon assimilation by chloroplasts; however, if stomata can close as a direct response to O3 then...
