Meeting Abstract 89.2 Friday, Jan. 7 Seeing through rocks: Chitons use calcium carbonate lenses to form images SPEISER, D.I.*; JOHNSEN, S.; Duke University; Duke University dis4@duke.edu Certain chitons, including the Caribbean Acanthopleura granulata, have hundreds of small (80-100 µm), lens-bearing eyes embedded in their dorsal shell plates. Using energy-dispersive x-ray spectroscopy (EDS) and x-ray diffraction, we found […]

Oxidative damage reduces reproductive output in the cooperatively breeding Florida Scrub-Jay
Meeting Abstract 88.5 Friday, Jan. 7 Oxidative damage reduces reproductive output in the cooperatively breeding Florida Scrub-Jay HEISS, Rebecca S. *; SCHOECH, Stephan, J. ; University of Memphis rsheiss@memphis.edu Oxidative damage results from the inability of an organism to cope with reactive oxygen species, formed as byproducts of metabolism. The resulting damage to various classes of biomolecules […]
