Three key functions are required for the long-term persistence of tree populations in a landscape. Broadly speaking, trees must acquire and allocate resources to maintain or increase their biomass, to tolerate or resist stress, and to pass genetic material to new generations. Yet the three central resource allocation pathways of growth, defence and reproduction have […] More
How will coastal ecosystems change when some seedling can tolerate rising tides, and others cannot? More
How much water does it take to turn an arid land into a hotbed of new life? More
Carbon released from the land surface is one of the largest fluxes of carbon dioxide (CO2) between the atmosphere and the Earth’s surface, with plant respiration accounting for about half of this flux. As a result, terrestrial biosphere models are highly sensitive to changes in plant respiratory processes. The thermal acclimation response of plant respiration […] More
As trees photosynthesize, using carbon from the atmosphere to grow and store energy, they also lose water to the air (transpire). During a drought, continuing to photosynthesize and transpire puts trees at risk of damaging their hydraulic conductivity and overall health. With growing seasons expected to lengthen with climate change in the northwestern USA, the […] More
Drosophyllum lusitanicum, also known as the Portuguese sundew or dewy pine, is unusual even for carnivorous plants in that it lives in dry environments. Typically, carnivorous plants live in nutrient-poor wetlands, so does it really gain much from carnivory? More
Salix herbacea, as other arctic-alpine species, likely found a refuge from the Ice Age in the Apennines. As the climate changed around them, the trees survived in a fragmenting population. This fragmentation has genetic consequences. More
Mosses are reacting to rising temperatures in the Antarctic in different ways. The tiny plants could cause big changes to the food web. More
