My current research focus is on plant phenology of trees and herbs in temperate deciduous forests. I have been documenting the timing of bud break, leaf expansion, leaf senescence, and flowering and fruiting for the last 12 years in a local forest fragment, Trelease Woods. This background data set serves as the springboard to address questions that can be answered experimentally. It also provides a long-term data set to evaluate questions about how global climate change is altering phenology. Currently, I am using the long-term data set to collaborate with investigators at the Harvard Forest and in France to determine the extent to which phenology imposes limitation on a species range distribution. Particular focus has been on plants growing in the shade of the canopy trees and how they may alter their phenology to avoid canopy shade and exploit high light periods. I have documented that, in addition to ephemeral herbs, the leaf phenology of understory saplings predates canopy closure in the spring by as much as three weeks. Subsequent studies have explored the environmental cue underlying this early phenology. I have found that adults and saplings use the same amount of thermal degree hours as their cue, but saplings accumulate degree hours faster and hence begin to leaf out earlier. I have also determined that these understory plants have the physiological capacity to take advantage of the added light in spring to enhance their carbon gain. A current experiment uses shade cloth to eliminate the high light spring phase of the understory individuals and is documenting their growth and mortality responses. Experiments with herbs determine the extent to which the herbs depend on the high light period and whether early cold temperatures or summer canopy shade impose greater limits on the phenology and growing period of many herbaceous species. My graduate students work in both temperate (Illinois, Utah, Louisiana) and tropical (Panama, Costa Rica, Peru, Ecuador, Honduras) habitats and generally focus on aspects of community ecology, especially seed and seedling ecology. Recent Ph.D. projects include dispersal, seed and seedling biology of the nutmeg tree by monkeys, restoration of abandoned pastures using living fence stakes to accelerate forest succession, community attributes that limit invasion by cheatgrass and garlic mustard, seedling ecology explaining patterns of primary tree succession on newly created river sandbars, historical factors explaining the rise in dominance of sugar maple in Illinois forests, and the inhibition of seedling recruitment by dwarf and arborescent tropical palms.

My research concerns the population and community ecology of tropical trees, with a particular interest in understanding how soil nutrient availability and soil microbial communities shape the composition and diversity of tree communities. Much of my work is carried out with collaborators at the <a href="http://www.stri.si.edu">Smithsonian Tropical Research Institute</a>, in Panama, either on <a href="http://www.stri.si.edu/english/visit_us/barro_colorado/index.php">Barro Colorado Island</a> or at the <a href="http://www.stri.si.edu/english/research/facilities/terrestrial/fortuna/index.php">Fortuna Forest Reserve</a>, where I maintain a network of forest dynamics plots described <a href="http://www.life.illinois.edu/dalling/publications/105.pdf">here</a>

My research program is focused on improving mechanistic understanding of: <ol> <li>Plant responses in natural and agricultural ecosystems to global environmental change</li> <li>Adaptation of food and fuel crops to global environmental change</li> <li>Sustainability of biofuel feedstocks</li> </ol> This will enhance understanding of how the environment impacts ecosystem goods and services including biodiversity, productivity, water cycling and food supply. To do this we combine molecular, biochemical, physiological and ecological tools to assess plant performance in manipulative field experiments and controlled environment chambers. On-going projects: <ol> <li>A systems-level analysis of drought and density response in the model C4 grass Setaria viridis</li> <li>EBI 2011: Sustainability of woody biofuel feedstocks</li> <li>Plants iView – an after school program in plant biology</li> <li>Altered Root-To-Shoot Signaling And Osmotic Adjustment As Key Determinants Of Soybean Stress Tolerance Under Drought And Elevated [CO2]</li> <li>Agroecosystems: Effects of changes in climate, carbon dioxide and ozone over the Central United States</li> <li>How will productivity, evapotranspiration & insect herbivory of the Midwest agroecosystem respond to the combined drought and elevated [CO2] anticipated for 2050?</li> </ol>
