Scaling and kinematics of tongue projection in chameleons
Price, C.L.*; Meyers, J.J.; Herrel, A.; Nishikawa, K.C.: Scaling and kinematics of tongue projection in chameleons Within a year from hatching, chameleons can grow up to two orders of magnitude. This rapid increase in body size likely imposes constraints on the function of chameleon muscles used for prey capture. In this study, we looked at […]
Isometric contractile properties of anuran jaw muscles and their relationship to feeding mechanics
LAPPIN, A.K.*; NISHIKAWA, K.C.; PIEROTTI, D.J.: Isometric contractile properties of anuran jaw muscles and their relationship to feeding mechanics All terrestrial frogs examined to date use tongue prehension to capture prey. Three categories of feeding behavior have been identified in frogs with respect to tongue performance during prey capture. Tongue performance characteristics that vary markedly […]
Hypoglossal sensory feedback control during feeding in the toad Bufo alvarius
DESROCHERS, D.M.*; NISHIKAWA, K.C.: Hypoglossal sensory feedback control during feeding in the toad Bufo alvarius This study explores the role of hypoglossal sensory feedback during feeding in the toad Bufo alvarius. Prior studies indicate that sensory feedback from the hypoglossal nerves can trigger inhibition of both tonic and phasic activity of the jaw levator muscles. […]
Does morphology correlate with prey capture kinematics in leptodactylid frogs
CARRE-O, C.A.*; NISHIKAWA, K.C.: Does morphology correlate with prey capture kinematics in leptodactylid frogs? Leptodactylid frogs exhibit diversity of the tongue and jaw mechanics during prey capture. Two mechanisms of prey capture have been seen in leptodactylids: inertial elongation and mechanical pulling. Phylogenetic analyses suggest that inertial elongation has evolved independently from mechanical pulling several […]
