Phenology and Productivity of C₃ and C₄ Grasslands in Hawaii

Creator:: Pau, Stephanie and Still, Christopher J.
Abstract:: Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by controlling for...

Assessing earth system model predictions of C-4 grass cover in North America: From the glacial era to the end of this century

Creator:: Still, Christopher J., Cotton, Jennifer M., and Griffith, Daniel M.
Abstract:: Aim C-4 grasses are distinct from C-3 grasses, because C-4 grasses respond in a different manner to light, temperature, CO2 and nitrogen and often have higher resource-use efficiencies. C-3 and C-4 grasses are typically represented in earth system models (ESMs) by different plant functional types (PFTs). The ability of ESMs...

The response of the ¹⁸O/¹⁶O composition of atmospheric CO₂ to changes in environmental conditions

Creator:: Buenning, Nikolaus, Noone, David, Randerson, James, Riley, William J., and Still, Christopher
Abstract:: This study investigates the response of the global mean and spatial variations of the δ¹⁸O value of atmospheric CO₂ (δCₐ) to changes in soil CO₂ hydration rates, relative humidity, the δ¹⁸O value of precipitation and water vapor, visible radiation, temperature, and ecosystem flux partitioning. A three-dimensional global transport model was...

Evaluating spatial patterns of drought-induced tree mortality in a coastal California pine forest

Creator:: Baguskas, Sara A., Peterson, Seth H., Bookhagen, Bodo, and Still, Christopher J.
Abstract:: In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality has occurred in the past in the stand we studied, this...

Creator:: Greer, Burke T., Still, Christopher, Howe, Glenn T., Tague, Christina, and Roberts, Dar A.
Abstract:: Quaking aspens (Populus tremuloides Michx.) are found in diverse habitats throughout North America. While the biogeography of aspens' distribution has been documented, the drivers of the phenotypic diversity of aspen are still being explored. In our study, we examined differences in climate between northern and southwestern populations of aspen, finding...

Polyploidy influences plant-environment interactions in quaking aspen (Populus tremuloides Michx.)

Creator:: Greer, Burke T., Still, Christopher, Cullinan, Grace L., Brooks, J. Renee, and Meinzer, Frederick C.
Abstract:: Quaking aspen (Populus tremuloides Michx.), a widespread and keystone tree species in North America, experienced heat and drought stress in the years 2002 and 2003 in the southwestern United States. This led to widespread aspen mortality that has altered the composition of forests, and is expected to occur again if...

Switching Hemispheres: A New Migration Strategy for the Disjunct Argentinean Breeding Population of Barn Swallow (Hirundo rustica)

Creator:: Garcia-Perez, Belen, Hobson, Keith A., Powell, Rebecca L., Still, Christopher J., and Huber, Gernot H.
Abstract:: Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...

Voter Displeasure: The Role of Dislike For the Opposition In the 2016 U.S. Presidential Election

Creator:: Schiek, Andrew
Abstract:: One of the surprising things about the 2016 presidential election was how much each presidential candidate was disliked. In this historic election, questions about whether voters made their decisions by supporting their candidate or voting against another have arisen. Studies have been done in the past that examine which traits...
