Paleontology and Paleoecology of Interglacial Guano Deposits in Mammoth Cave, KY

Mammoth Cave guano deposits contain a rich record of troglofauna spanning the last 125,000 years. In particular, chiropteran remains from Chief City provide insight into ecosystem dynamics of the cave area during the last interglacial. This paper presents results of paleontological excavations undertaken in 2008. Sub-fossil remains (N=1134) in Chief City guano deposits are dominated by chiropteran taxa. Although all identified taxa are extant, the combination of Myotis leibii and Tadarida brasiliensis is an association without modern analogue. Stable isotope analyses of guano indicate a C3 prey signature characteristic of forested habitat. This was unexpected given the prevalence of T. brasiliensis, a species that is typically associated with open environments. Ecomorphological consideration of wing shape trends in these assemblages indicate that interglacial faunas are dominated by fast-flying, open-space taxa (T. brasiliensis) while late Holocene and Historic assemblages contain more taxa that utilized closed forest or forest gaps

Designing hollow nano gold golf balls.

Hollow/porous nanoparticles, including nanocarriers, nanoshells, and mesoporous materials have applications in catalysis, photonics, biosensing, and delivery of theranostic agents. Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without silica. The template consisted of 100 nm polystyrene beads attached to a larger silica core. Selective gold plating of the core followed by removal of the polystyrene beads produced a golf ball-like nanostructure with 100 nm pits. Dissolution of the silica core produced a hollow/porous golf ball-like nanostructure

The State of the Region: Hampton Roads 2002

This is Old Dominion University\u27s third annual State of the Region report.While it represents the work of many individuals connected in various ways to the university, the report does not constitute an official viewpoint of the University, or it\u27s president, Dr. Roseann Runte. Our State of the Region reports maintain the modest goal of making Hampton Roads an even better place to live. We are proud of our region\u27s many successes, but realize that it is possible to improve the region\u27s performance. Yet, in order to improve our performance, we must have accurate information about where we are and a sound understanding of the policy options open to us. This year\u27s report places particular emphasis upon providing up-to-date information on how Hampton Roads compares to other regions nationally.https://digitalcommons.odu.edu/economics_books/1016/thumbnail.jp
