Meeting Abstract 97-10  Wednesday, Jan. 6 14:15  Slotted feathers aren’t just for efficiency KLAASSEN VAN OORSCHOT, B*; TOBALSKE, B.W.; Univ. of Montana brett.kvo@umontana.edu http://www.brettkvo.com Soaring birds including hawks and vultures exhibit emarginated primary feathers that collectively create a slotted wing-tip. Research has indicated these wing-tip slots reduce induced drag, resulting in a more efficient wing (i.e. better […]

Meeting Abstract 97-1  Wednesday, Jan. 6 13:30  Premaxillary protrusion in the ribbonfishes: extreme suction production in the mesopelagic realm? FERRY, LA*; PAIG-TRAN, EW; Arizona State; Cal State Fullerton Lara.Ferry@asu.edu http://morphology.asu.edu Jaw (premaxillary) protrusion is thought to be a key innovation correlated with the subsequent radiation and diversification of fishes. Extreme amounts of protrusion are associated with suction […]

Meeting Abstract 97-9  Wednesday, Jan. 6 14:10  Optimal quadrupedal locomotion SRINIVASAN, M.; The Ohio State University srinivasan.88@osu.edu http://movement.osu.edu/publications.html Horses walk at slow speeds, trot at intermediate speeds, and gallop at high speeds. Other quadrupeds, including trained horses, can perform a variety of other gaits, such as an amble, pace, canter, tolt, etc. Here, we use a series […]
