ROBERTS, S. P.*; FEDER, M.E.; POSLUSZNY, J.A: Developmental and fitness consequences of natural thermal stress and hsp70 copy number in Drosophila melanogaster Natural heat exposure of larval Drosophila melanogaster results in high rates of larval mortality and severe developmental defects in eclosing adults. Transgenic increases in copy number of the gene encoding the major inducible […]

FERRY-GRAHAM, L.A.; WAINWRIGHT, P.C.; LAUDER, G.V.: Sources of fluid flow during feeding in bluegill sunfish as identified using DPIV Two key predictions of the fluid mechanics literature have never been tested empirically in suction feeding fishes. First, it is expected that the velocity of flow into the mouth during buccal expansion will decrease exponentially with […]

MONROY, J.A.; ANDERSON, C.W.; NISHIKAWA, K.C.: Neural control of feeding in microhylid frogs In this study, we investigated the neural pathways involved in the control of feeding behavior in microhylid frogs. Microhylid frogs use a muscular hydrostatic mechanism to protract their tongues and have the unusual ability to aim their tongues independently of their heads […]

PLATT, J.P.*; TURINGAN, R.G.: Kinematic and behavioral consequences of diet-induced phenotypic plasticity in the feeding morphology of sheepshead, Archosargus probatocephalus Studies of phenotypic plasticity in fishes commonly focus on the correlation between diet and morphology of the feeding apparatus, but few studies have directly measured the performance consequences of diet-induced morphological changes. We conducted a […]

SWANSON, B.O.: Intra-specific competition in a polymorphic cichlid, Herichthys minckleyi: Does variation in jaw morphology lead to resource partitioning? At least two distinct prey processing morphotypes are observed in the Cuatro CiÉnegas cichlid (Herichthys minckleyi). One morphotype has gracile pharyngeal jaws with papilliform pharyngeal teeth. The other morphotype has robust pharyngeal jaws and molariform pharyngeal […]

WAINWRIGHT, P.C.*; FERRY-GRAHAM, L.A.; WALTZEK, T.B.; HULSEY, C.D.; CARROLL, A.M.; SVANBACK, R.: Evaluating suction feeding performance in fishes There is no widely-accepted metric for evaluating suction feeding performance, in spite of the widespread use of this method of prey capture among vertebrates. We studied the efficacy of Suction Distance, the distance over which the prey […]

OCONNOR, P.M.; Ohio University College of Osteopathic Medicine: Pulmonary Pneumaticity in the Postcranial Skeleton of Extant Anseriforms Anseriform birds were surveyed to examine how the degree of postcranial pneumaticity varies in a behaviorally and size-diverse clade of birds. This study attempts to extricate the relative effects of phylogeny, body size, and behavioral specializations (e.g., diving) […]

CLIFFORD, A. B.; WITMER, L. M.; Ohio University, DBS; Ohio University, DBMS: Nasal Structures in Moose (Cervidae: Alces) Moose are a species of deer possessing a conspicuous overhanging muzzle. The functional significance of this apomorphic proboscis has remained obscure, and thus, we studied the anatomy of moose noses in an attempt to shed light on […]

RAFFERTY, K.L.; HERRING, S.W.*; Univ. of Washington; Univ. of Washington: In Vivo Biomechanics of the Snout The snout is a large diameter, thin-walled tubular structure that receives loads from the teeth. It can be conceptualized both as a rigid object and as an assemblage of several bones that interface at sutures. To gain a better […]

BERGMANN, P.J.*; RUSSELL, A.P.; University of Calgary, Calgary; University of Calgary, Calgary: Growth of the original tail in iguanian lizards: Are segmental patterns of growth conserved? The original tail of lizards is composed of discrete, serially repeating vertebrae. Segmental (vertebral) patterns of tail growth were modeled using principal component analysis and compared to geometric mean […]
