Numerous conference presentations, invited seminars, and publications have resulted from this work (see Publications). In addition, we have developed an educational video that demonstrates feeding processes in bivalves, and I have participated in the making of an Open University, teaching video that explores the functional biology of suspension feeders.

A. Videos for general interest and education
||Particle Selection in Oysters: medium format (see Ward et al. 1997, Nature, 390: 131-132)
||* NEW ** Summary of Particle Feeding in the Mussel, Mytilus: medium format
B. Video produced by the BBC for the Open University (UK).
||This video summarizes suspension feeding processes in bivalves and
includes endoscopy sequences. It was produced as part of Open University's Uniformity and Diversity series. Click on the link to the left and then select "Investigating Bivalves."
C. Videos to support data and interpretations presented in Ward et al. (1998, L&O, 43: 741-752) and Ward et al. (2000, L&O, 45: 1203-1210)
These video sequences demonstrate the important points concerning in vivo observations of feeding and our particle capture model. Please see the above papers for a full explanation of data presented in the video clips.
Note: Video clips have been compressed to reduce disk storage space and down-loading time. For best viewing, dim room lights and adjust monitor brightness and contrast if needed. Quality of images will vary depending on quality of the video card and monitor of your computer system. Original images are of higher quality.
Digitized, video micrographs of particle kinematics above and along the frontal surface of the ctenidia (=gill) of two filibranchiate bivalves. Particles (white dots) were positioned on micrographs to illustrate specific paths obtained by motion analysis.
Numbers indicate cumulative frame advances for a given position of the particle (0.033-s time steps, NTSC). The x indicates position of particle when it first contacted a given ctenidial filament. Scale bars are about 100 µm.
