The general audience will be invited to leave after the presentation and Q & A session.Title: Quantifying Scale Dependence of Hydraulic Conductivity in Glacial Sediments for Improving Predictions of Plume BehaviorAbstract:Methods targeting a range of measurement scales are used to quantify the variability in hydraulic conductivity (K) for ice marginal sediments comprising a shallow unconfined aquifer at a contaminated groundwater site. Grain size analysis is used to estimate K at the decimeter...

The general audience will be invited to leave after the presentation and Q & A session.Title: A Phylogenetic Reconstruction of North American Goniopholidid CrocodyliformesAbstract: Goniopholididae are distant relatives of crocodiles and alligators from the Jurassic and Cretaceous (201- 66 mya) of North America and Europe. They are the first in this lineage with a body plan and, presumably, ecological role superficially resembling those of modern crocodylians. The flat, triangular skull and...

What types of plants, animals, and fungal life might you find at the Ashton Prairie Living Laboratory? Let's find out!  Join researchers in collecting, observing, and recording biodiversity at the Ashton Prairie Living Laboratory in our 5th Annual BioBlitz. Your findings will inform a major research project and will contribute to the fifth data point in a multi-year documentation of how diversity changes at this site over time. Collections will be housed with the UI Museum of Natural History...
