Scanning Electron Micrograph of Pedicellaria – Judge's Choice 2014

P. ochraceous pedicellaria responding to contact with another species of sea star taken by Haila Schultz ’16 on our Hitachi S3400N SEM. These comparisons will shed light on competition between sea star species and development of pedicellaria size.


Fluorescence in situ Hybridization of sulfide-oxidizing bacteria – People's Choice 2014

Sediment from Commencement Bay visualized with fluorescent probes specific for sulfate-reducing bacteria taken by Cheyenne Dewey '16 on our Nikon D-Eclipse C1 Microscope. Identification of populations of these bacteria could serve as an indicator for toxic environmental conditions.


Scanning Electron Microscopy of Lichen Holdfasts - Winner Fall 2013

Observation of tissue segregation in a folios lichen (Parmelia spp.) taken by Kelsey Crutchfield-Peters '14 on our Hitachi S3400N SEM. It is important in studying how tissue structure, and symbiont abundance, changes within the lichen in response to environmental factors.
