Meeting Abstract 4.2  Monday, Jan. 4  Effects of elevated atmospheric CO2 on growth in newly-settled coral polyps ROGERS-LOWERY, CL; Catawba College clowery@catawba.edu As levels of atmospheric carbon dioxide increase due to anthropogenic causes, it is projected that the pH of the oceans will become more acidic. Lower pH decreases aragonite saturation of seawater and may, as a […]

Meeting Abstract 4.4  Tuesday, Jan. 4  Preventing Damage: Absorbtion of Kinetic Energy in Locust Kicks SUTTON, GP*; BURROWS, M; University of Cambridge; University of Cambridge RScealai@gmail.com While it is well known that insects use cuticular springs to store and quickly release energy, we will show that they also use cuticular springs to absorb and dissipate energy. When […]

Meeting Abstract 4.3  Tuesday, Jan. 4  Dynamic mechanical properties of resilin through the glass transition KING, RJ*; DUDEK, DM; Univ of Utah; Virginia Tech dmdudek@vt.edu Resilin is an almost perfect elastic protein found in many insects. It can be stretched up to 300% of its resting length and is unaffected by creep or stress relaxation. While much […]

Meeting Abstract 4.1  Tuesday, Jan. 4  Cross-linking by protein oxidation in gastropod glues SMITH, A.M.*; BRADSHAW, A.; SALT, M.; BELL, A.; LITRA, N.; Ithaca College, NY; Ithaca College, NY; Ithaca College, NY; Ithaca College, NY; Ithaca College, NY asmith@ithaca.edu Protein oxidation is a common phenomenon that causes protein dysfunction in aging, but it can also be harnessed […]

Meeting Abstract 4.5  Tuesday, Jan. 4  Cellular Materials in Nature GIBSON, LJ*; ASHBY, MF; MIT; Cambridge University ljgibson@mit.edu Cellular materials are widespread in nature. Wood and cork have a honeycomb-like structure with cells that are roughly hexagonal prisms. Trabecular bone, plant parenchyma, adipose tissue, coral and sponge all have a foam-like structure, with polyhedral cells. Natural structures […]

Meeting Abstract 4.4  Wednesday, Jan. 4  Ontogenetic evidence and performance consequences of re-acquisition of planktotrophy in the gastropod family Calyptraeidae MCDONALD, K.A.; Smithsonian Tropical Research Institute characterforming@gmail.com Phylogenetic hypotheses suggest that different lineages of calyptraeid gastropods have regained free-swimming, feeding larvae following loss of the ancestral type of planktotrophic development. This runs counter to expectations based in […]

Meeting Abstract 4.5  Wednesday, Jan. 4  Maternal provisioning in echinoids: the role of egg constituents during pre-feeding larval development MCALISTER, J/S*; MORAN, A/L; Clemson University; Clemson University jmcalis@clemson.edu Marine invertebrates with feeding larvae utilize maternally-provisioned material (protein, lipid, and carbohydrate) in the egg for morphogenesis and metabolism during early pre-feeding larval development. All eggs are not provisioned […]
