SHADWICK, R.E.*; STEFFENSEN, J.F.: The cost and efficiency of aerobic locomotion in the chub mackerel (Scomber japonicus). The cost of aerobic locomotion in the chub mackerel was investigated at different steady swimming speeds in a water tunnel respirometer. Eight fish, 25 to 30 cm in length (L), and 145-199g mass were used at 14-15oC. O2 […]

Stakebake, E.F.; Meyers, R.A.*: The albatross shoulder lock: A biomechanical and immunohistochemical study. As a postural behavior, gliding and soaring flight in birds requires less energy than flapping flight. Slow tonic and slow twitch muscle fibers are specialized for sustained contraction with high fatigue resistance and are typically found in muscles associated with posture. Albatrosses […]

Kozlowski, C.P.*; McIntyre, J.C.; Moore, P.A.: The Winning Effect in Agnostic Encounters of Crayfish is a Time Dependment Phenomenon Previous studies have shown that fighting behavior is the fundamental method for determining dominance between crayfish. Many factors are responsible for determining dominance, including the crayfish’s previous fighting experiences. It has been shown that a crayfish […]

MEAD, K. S.: The Mechanisms Of Turbulent Action: How Does Hydrodynamic Shear Stress Affect Fertilization And Development In Sea Urchins? Marine invertebrates that reproduce by external fertilization release their eggs and sperm into the water column. For animals living in the surf zone, this means that their gametes are exposed to high energy dissipation rates […]

Kymbr L. Wright; Dr. Stan Kuczaj: The Effects of Time of Day on Mother-Infant Association Patterns of Bottlenose Dolphins (Tursiops truncatus) in Captivity Behavioral data on association patternsbetween mothers and their infants are spares. This study compares the behavioral patterns of four mother-infant pairs over a two-month period. The data was collected using instantaneous sampling […]

KRAUS-EPLEY, K.E.*; MOORE, P.A.: The Effects of Antennal Lesions on Orientation Behavior of the Crayfish, Orconectes rusticus Numerous animals use chemical cues within their environments to execute various behaviors. One of these behaviors is orientation to a food source. Crayfish, in particular, can orient to food sources under a number of different conditions. It has […]

Sheets, D.H.*; Zelditch, M.L.: Studies of Shapes with Bilateral Symmetry The first step in any comparison of shapes is putting them in a common framework or registration, which is done by superimposition. Superimposition involves placing shapes on top of each other, mathematically rescaling them, and sometimes rotating them so that they differ as little as […]

WEBSTER, M.D.*; CHAPLIN, S.B.: Student initiated projects in animal physiology lab instruction. To enhance student learning of physiological concepts, build a departmental culture of inquiry, and motivate students to pursue studies of animal biology, we use independent laboratory projects as a primary mode for instruction in our comparative animal physiology courses. Students are first exposed […]

BERTRAM, J.E.A.*; RUINA, A.; COX, D.E.; KATSANOS, C.S.: Speed, step length and frequency in human walking: evaluating the optimization criteria. Locomotion is an active process that involves an interaction between physiological and physical features of an organism. The result of this interaction is the overt functional behavior of the system, its capabilities and limitations. But […]

Cupp, P.V.: Spatial Distribution and Site Fidelity in Green Salamanders, Aneides aeneus. Individual green salamanders, Aneides aeneus (N=94) were captured and identified by the unique pattern of black spots on their heads. Individuals were then returned to the rock crevices from which they had been removed. Additional visits were made to the same areas in […]
