SWARTZ, S. M.; BISHOP, K. L.; ISMAEL AGUIRRE, M. F.; STOCKWELL, E. S.; SKENE, J. A.: Large-scale deformations in the wing bones of flying bats During flight, bat wings move through space in a three-dimensionally complex way. When we quantify wingbeat amplitudes and frequencies, we capture some proportion of that complexity, but neglect some aspects […]

Computer Modeling of Complex Integumentary Structures Digitally Generated Birds and Feathers
SUMIDA, S.S; REDD, J.; BRUDERLIN, A.: Computer Modeling of Complex Integumentary Structures: Digitally Generated Birds and Feathers Digital modeling of muscles, bones and integument of dinosaurs and mammals has progressed farther than any other group to date. Homeotherms present particular difficulties due to the complexity of their insulating hair or feathers. Modeling complex integumentary structures […]
Suction Feeding Performance in the Largemouth Bass Micropterus salmoides Linking Buccal Cavity Kinematics using Sonomicrometry to Pressure
SANFORD, C. P.*; WAINWRIGHT, P. C. : Suction Feeding Performance in the Largemouth Bass Micropterus salmoides: Linking Buccal Cavity Kinematics using Sonomicrometry to Pressure Suction feeding in fishes is the result of highly coordinated explosive expansion of the buccal cavity that results in the generation of subambient pressures. Buccal expansion draws water into the oral […]
Functional and morphological bases of intraspecific variation in the feeding ecomorphology of largemouth bass, Micropterus salmoides
HUSKEY, S.H.*; TURINGAN, R.G.: Functional and morphological bases of intraspecific variation in the feeding ecomorphology of largemouth bass, Micropterus salmoides The strength of intraspecific ecomorphological studies is in their ability to focus on adaptive processes within a single species, thus eliminating the inherent confounding effects of phylogeny present in interspecific comparisons. To investigate the effects […]
Coupled vs decoupled feeding systems diet-induced plasticity in the feeding mechanism of Archosargus probatocephalus
FOUGEROLLE, M.F.*; TURINGAN, R.G.: Coupled vs. decoupled feeding systems: diet-induced plasticity in the feeding mechanism of Archosargus probatocephalus The biomechanical basis for the ability of A. probatocephalus to consume both soft and hard prey organisms within its environment was examined in an attempt to understand the mechanisms that underlie the ubiquitous distribution of this species. […]
African Swamps and Respiratory Tradeoffs Interdemic Variation in an Air-Breathing Catfish, Clarias Liocephalus
MCCUE, M.D.; CHAPMAN, L.J.: African Swamps and Respiratory Tradeoffs: Interdemic Variation in an Air-Breathing Catfish, Clarias Liocephalus All air-breathing fishes are bimodal and use their air-breathing organs to extract atmospheric oxygen and gills to extract aquatic oxygen, however there is great variation among species in their dependence on aerial respiration. This study was designed to […]
Proboscis Evolution in Mammalia Preliminary Studies
CLIFFORD, A.B.; WITMER, L.M.: Proboscis Evolution in Mammalia: Preliminary Studies Specialized narial anatomy in Mammalia is involved in such diverse functions as manipulation, vocal and visual communication, sensation (both mechanosensory and olfactory), and physiological regulation (water and heat balance). Various clades have independently evolved a specialized narial structure often referred to as a proboscis. This […]
Lung Ventilation during Treadmill Locomotion in Terrapene carolina
LANDBERG, Tobias*; MAILHOT, Jeffrey; BRAINERD, Elizabeth L.: Lung Ventilation during Treadmill Locomotion in Terrapene carolina. Turtles are unique in that their shells essentially contain a fixed volume. As a result, when the head or limbs are retracted or protracted, air may be forced into or out of the lungs. Resting turtles may actively ventilate the […]
Growth versus repair responses to loading in mammalian limb bones
LIEBERMAN, DE; PEARSON, OM; POLK, JD: Growth versus repair responses to loading in mammalian limb bones Bones respond to mechanical loading either through growth (modeling) or repair (remodeling), but how and why bones modulate these two processes is poorly understood. Most models propose that modeling and remodeling are coordinated to maintain mechanical equilibrium, adapting functionally […]
Foot Morphology and Water-bounding in the Nazca Booby
MORGAN, S. M. *; ASHLEY-ROSS, M. A.; ANDERSON, D. J.: Foot Morphology and Water-bounding in the Nazca Booby Nazca Boobies (Sula granti) have totipalmate feet, meaning they have webbing between all four of their toes. These birds use their unique feet in several aspects of their biology, including aiding them in taking off from the […]
