Lauren Houdek ('09, Biology). James J. Whalen Academic Symposium, Ithaca College. April, 2009. Under the supervision of Jean Hardwick. Her presentation was entitled, "Enzyme Expression in Neurons that Regulate Guinea Pig Cardiac Function".
Andy Smith presented a talk in the symposium, "Biomaterials: properties, variation and evolution", at the annual conference of the Society for Integrative and Comparative Biology. The talk was titled “Multiple cross-linking mechanisms in molluscan adhesive gels”, and was co-authored by two IC students, Sarah Garcia and Aaron Bloom. Boston, MA. January 2009.
Abstract:
Some terrestrial slugs produce remarkably sticky and elastic gels as defensive secretions. Previous work on these gels has shown that metals play a central role in their cross-linking. The transition metals iron and zinc are common in these gels, as are calcium and magnesium. A major question is how these metals cross-link the gel, and whether there is more than one mechanism by which they do so. Chelation of metals with EDTA for an extended time breaks down the mechanical integrity of the gel, thus demonstrating a direct effect of the metals on gel mechanics. Furthermore, metals, particularly calcium, were shown to have a general stiffening effect on commercial gels at the concentrations seen in the glue. Metal removal does not completely break down the gel, however, as size exclusion chromatography experiments show that the major cross-links involve a 40 kDa protein and these are unaffected by metal chelation after the glue sets. If chelation occurs before the glue sets, however, this cross-link does not form either. Measurements of the stiffness of commercial gels with metals and glue proteins added separately and together show that both stiffen gels on their own, but the effect is merely additive; they are not necessarily interdependent. The findings suggest that the mechanical strength of the gel depends in part on metals such as calcium and zinc forming direct cross-links and also on other cross-links involving the 40 kDa protein, which are catalyzed by metals before the glue sets.

Andy Smith presented the talk, "Metals, molluscan glues and gel mechanics" at the annual meeting of the Society for Integrative and Comparative Biology, January 6, 2008 in San Antonio, Texas.
Metals, molluscan glues and gel mechanics. SMITH. A. M. Ithaca College. Molluscan adhesive gels possess many useful properties, most notably their remarkable combination of strength and deformability, as well as their ability to adhere to wet, irregular surfaces. Recent work has found that the glue of the terrestrial slug Arion subfuscus contains substantial amounts of iron, manganese, zinc and some copper. Furthermore, the presence of transition metals was critical for the glue to set. This study addresses the relative roles of the different metals. Do they all function similarly, with similar effectiveness? Are they incorporated into the glue in a similar way? We used atomic absorption spectroscopy to characterize the metal content of several different gastropod glues. We also tested the effect of these metals on the mechanics of several commercial gels. The metal content of the glue from the terrestrial snail Helix aspersa and the terrestrial slugs A. subfuscus and Ariolimax columbianus was markedly similar. When hydrated, all three had over 40 mM calcium and 0.07-0.08 mM iron. A. subfuscus also had 0.9 mM zinc while A. columbianus had 0.5 mM manganese. For comparison, sodium and chloride concentrations were roughly 10 mM. Soaking A. subfuscus glue in EDTA caused all the metal concentrations to drop to 1-5% of their original value, except iron, which was not significantly different (t-test, P = 0.18). All the metals stiffened agar and pectin gels. Notably, despite its poor solubility iron was 20-40x as effective as calcium. Zinc was roughly 10x as effective as calcium. These results suggest that iron is more effective in controlling the gel mechanics than other metals, and it is more tightly incorporated into the glue. The other metals are present in higher concentrations, so they would still contribute substantially, but likely in different ways.

Kirwin Providence and Sarah Kessler presented a poster entitled, “Desmid Adhesion Mechanisms: A prelude to eukaryotic and biofilm formation”. 2007 Annual Symposium in Plant Biology, University of Massachusetts-Amherst. October 2007.
Abstract:
Adhesion is a fundamental cellular process used by all kingdoms of life. The formation of biofilms (highly structured microbial communities) requires the secretion of adhesive substances. In many freshwater wetland ecosystems, photosynthetic algae (desmids) play important roles in the formation, structure, and function of biofilms.
Central to most adhesion processes is the production and secretion of extracellular polymeric substance (EPS). The EPS is a carbohydrate rich matrix of molecules that is secreted beyond the cell wall. Previous research demonstrates that proteins are embedded in desmid EPS. This observation suggests that proteins (either independently, or in concert with EPS) may support cell binding to substrates.
Using the desmid Penium Margaritaceum as the model organism, we test the hypothesis that proteins mediate initial desmid-substrate binding. This binding event is important in that it is a prerequisite supporting the transitioning from the planktonic realm to biofilm formation and subsequent benthic community development.
We demonstrate that EPS-devoid cells are able to adhere to abiotic substrates. This binding is dependent on peripheral proteins associated with the desmid cell wall and or plasma membrane. These observations increases our knowledge about this major group of microorganisms that may be keystone species in wetland habitats, and ones that profoundly affect environmental concerns such as water quality, pollution remediation, and disease control.
Susan Swensen and Marian Brown (Provost's Office) presented a series of ten posters entitled "Exploring Positive Growth: The Sustainability Initiative at Ithaca College." The conference, "Greening of the Campus VII" was held at Ball State University, Muncie, IN. September 2007. View the full report as a PDF here.
Abstract:
Ithaca College has undertaken a campus-wide sustainability initiative with three major areas of focus: faculty research into related fields of study and active support for curriculum modification to infuse considerations of sustainability into courses across disciplines; campus operational reforms to become more sustainable and to provide a supportive living-learning environment that models the theory and principles presented in our classrooms; and communication within our campus community and outreach to our surrounding community in the region. We will offer a comprehensive poster session that includes presentations and displays from all the various participants involved in the Ithaca College sustainability initiative; this will include (but not be limited to) each of the following related programs and activities: Curriculum and Research, Campus Operations, and Communication and Outreach.

Bruce Smith and Will Brogan ('07) gave a poster presentation entitled “Habituation of male /Arrenurus manubriator (Acari: Hydrachnida) to female sex pheromone”. Mid-Atlantic Ecology Conference (Mid-Atlantic branch meeting, Ecological Society of America). York, PA March 2007.
Abstract:
Male Arrenurus manubriator mites were tested to determine whether response to female pheromone decreased with increased duration of exposure. Groups of virgin males were housed with a single virgin female for 1, 24, 48 or 72 hours. Males were exposed to pheromones during this period, but were not allowed direct contact with the female. The males’ response was tested in a circular arena divided into an central circle and an outer ring. Groups of 50 males were introduced to the arena, and either 0.6 ml of untreated water (negative control) or female-conditioned water (test groups and positive control) was injected into the center of the dish. Observations over time were used to determine when maximal responses to pheromone occur, and hence the optimal time for comparisons among treatments. Five groups of positive controls confirmed that sufficient pheromone was present and that males were responsive, and also indicated that the peak response occurred approximately 180 sec. after introducing pheromone to the arena. In trials involving 1 and 24 hr. pre-exposure to pheromone, males responded just as strongly to pheromone as did positive control groups. After 48 and 72 hours of exposure to female pheromone, significantly fewer males responded during observation intervals.

Andy Smith presented "Adhesive gels from snails and slugs: strong, highly flexible glues that depend on iron" at the annual meetings of the Adhesion Society. Tampa, FL. February 2007
Abstract:
Gastropod molluscs such as snails and slugs can create strong, temporary adhesion using dilute gels. These gels consist of over 95% water, yet can adhere to a wide variety of surfaces with tenacities that typically range from 100 to 500 kPa. Because of the novel characteristics of these glues, there is good potential for biomimetic applications. Thus, a major goal is to identify the mechanism that makes these dilute gels adhesive. The key structural feature of these glues is the presence of gel-stiffening proteins that have been called “glue proteins”. Recent work has identified several important biochemical features of these proteins, the most striking of which is their association with iron. Removing or binding this iron with a highly specific iron chelator blocks the ability of the glue proteins to function in a variety of different assays. These observations suggest several possible mechanisms by which the glue proteins may act.
Andy Smith presented “Gluing with an iron fist: crosslinking in molluscan adhesive gels “ at the Society for Integrative and Comparative Biology Meeting. Phoenix, AZ. January 2007.
Abstract:
Many gastropod molluscs produce strong adhesion with soft, dilute gels. A major question is how such gels can become powerful adhesives. Previous research has identified specific glue proteins that appear to crosslink the gels and may be involved in interfacial adhesion, but the mechanism has not yet been identified. We studied the rapidly-setting defensive glue secreted by the slug Arion subfuscus. The proteins that constitute this gel are sensitive to the presence of iron. Atomic absorption spectroscopy on the dissolved glue and iron-specific stains on blots of the proteins show that the primary glue protein has iron bound at approximately a 1:1 molar ratio. This is the only protein in the glue that binds to iron strongly. Removal or binding of this iron with a high-affinity, iron-specific chelator shows that iron plays a major role in the function of the gel. Chelation of iron may inhibit the setting of the glue, as demonstrated by a marked increase in solubility when the chelator is added before the glue sets. Chelation also completely blocks the ability of the glue proteins to function in a gel-stiffening assay. This evidence suggests that iron associated with the glue proteins participates in crosslinking reactions that are essential for the mechanics and integrity of the gel. A mechanism involving iron could explain the ability to form strong, non-specific adhesion with dilute glues in an aqueous environment.
