Uncovering A Natural History Mystery At The University Of Akron, Gary M. Holliday, Lara Roketenetz
Proceedings from the Document Academy
Students were engaged in a combination of detective work, biology, archives, art, and education/outreach to prepare a collection of taxidermied birds donated to the University of Akron by the Rhodes family in the early 1900s for public access and exhibition. Students had the opportunity to learn from leading experts regarding the historical significance of biological collections, proper preservation protocols, digitizing and archival practices, and the urgency of science education and communication for a public audience. Many campus and community partners were involved, including experts from local museums and nature centers.

The oral behavior of drinking includes interactions between the tongue, jaw, and liquid being ingested to provide hydration to the animal. Different mechanisms may be used to ingest liquid such as lapping, licking, or sucking. The objective of the study was to compare the mechanism of lapping across marsupial species through comparison of the length of gape cycle, and the amplitude of jaw pitch and tongue protraction between the two marsupial species, Didelphis virginiana and Monodelphis domestica. I hypothesized that there would be no differences in any of the variables for the lapping mechanism between species. Previous work demonstrates …

Both the number and the density of flowering plants in a population can be important determinants of pollinator abundance and behavior. We report the joint effects of population size and density on pollinator visitation and pollination success for Lupinus perennis (Fabaceae). Focusing on five pairs of populations, we matched one small population (125-800 flowering plants) with one distinctly larger population (1000-3000 flowering plants). In these pairs, population size did not affect pollinator communities or pollination success. All measures of pollination success increased significantly with density. Only bee behavior (number of flowers probed per inflorescence) exhibited a significant interaction of size …
