Carbon Tree Demonstration

Carbon Tree animation is based on the measurements at the SMEAR II station and on the Carbon Tree website you can monitor how the medium-sized pine in Southern Finland exchanges carbon dioxide in real time. In addition to the website, there is also the Interactive Carbon Tree exhibition stand (see photo on the left), including physical user interface that allows a viewer to adjust environmental conditions of the Carbon tree: one can, for instance, increase the air temperature by warming the sensor with a hand or increase CO2 concentration by blowing air towards it. The changes affect carbon flow immediately.

Beetles, Mammals, and Plants: Is Climate Driving Range Shifts Since the Last Glacial Maximum

In this exercise, students will learn how organisms responded to the change in climate since the last glacial maximum (LGM) in North America. Using the Neotoma database and ArcGIS Online, students will create taxon modern distribution maps for the species of beetles, mammals, and plants found at the Conklin Quarry fossil site in eastern Iowa. By comparing the modern species ranges of these taxa, students will interpret what the environment may have been like in eastern Iowa during the LGM.
