Retired Educators Tour

This is a private tour scheduled for retired educators and led b docent Randall Smith.

The Gold Throne of Tutankhamun

The “Gold Throne” (Carter object no. 91; Cairo JE 62028) is one of the best-known objects from the tomb of Tutankhamun (KV62). It is also one of the more intriguing, since its backrest scene shows clear evidence of having been altered in antiquity. What were the nature and extent of these changes? And what light do they shed on the complexities of the later Amarna Period?

Meet the Artists of “Marking Time to a Changing Climate”

The artists of the current exhibit in the Bannister Building, Marking Time to a Changing Climate, will describe their work.

Please note that there is a public tour of the art exhibit in the half hour before the talks.

Parris Humphrey PhD Defense

The public portion of the PhD Defense Talk is from 10AM-11AM.  

Tree rings go global: the use of large networks in environmental change research

A major goal of current environmental change research is to add more realism to projections of ecosystem functioning in a warming world. This requires a large-scale understanding of plant responses to climate variability and change. Forests in particular are a major player in the coupled biosphere-climate system and critically determine terrestrial carbon cycling. Studying tree growth on multiple spatiotemporal scales is thus a prerequisite to develop robust benchmarks e.g. for vegetation model simulations of forest productivity.

Longitudinal Variation in Wood Accumulation Along the Stem of Populus grandidentata: Implications for Forest Carbon Monitoring

Direct measures of forest wood production are often based on measures of individual tree growth along the stem, often taken at a single height: basal height (1.3 meters). This assumes that a measurement of wood production at a single height is representative of wood production along the whole stem. In violation of this assumption, it is known that trees do accumulate wood differentially along the stem.

A Tree-Ring Perspective on the Impact of Climate Change on North American Tree Growth

The fate of forests in a warming world is of major ecological, societal, and economic concern. Forests play a key role in the combined carbon-water-nutrient cycle, including important ecosystem services and feedbacks to the climate system. Historically, forests have been an important carbon sink because of an excess of net primary production (NPP) compared to ecosystem respiration, but the future of this carbon sink is increasingly in question, as NPP may decline in a warming world.
