Knutzen, M.: Turtles in Minature: An Investigation into Hatchling Size Manipulation Eggs Of Apalone mutica were assigned to a yolk manipulation treatment(control, sham, 0.5 g removal, or 1.0 g removal) and incubated in moist vermiculite (-150kPa) at about 30.5 C. Three eggs from each of 7 clutches were assigned to each treatment for a total […]

Truman State University students and evolution a survey
Sanders, N.K.*; Mayo, M.; Stuart, J.: Truman State University students and evolution: a survey. Recent media attention has refocused the American public on the teaching of evolution in public schools. Nationwide, differences in state standards for science education offer a wide variety of possibilities of how to teach about evolution � or not – for […]
To steal or not to steal That is the question Suspension feeding versus kleptoparasitism in a marine snail
IYENGAR, E.V.: To steal or not to steal? That is the question. Suspension feeding versus kleptoparasitism in a marine snail. Although suspension feeding is a dominant feeding mode in the marine realm, is performed by members of many diverse taxa, and has evolved at least seven times within the prosobranchs, suspension feeding is rare among […]
Three-dimensional kinematics of level flight in the Egyptian Fruit Bat, Rousettus aegyptiacus
SKENE, J.A.*; FISCHER, I.M.; HUBER, M.H.; HEDRICK, T.; STOCKWELL, E.S.; SWARTZ, S.M.: Three-dimensional kinematics of level flight in the Egyptian Fruit Bat, Rousettus aegyptiacus To understand the functional and evolutionary significance of the diversity of bat wing morphologies, it is critical to understand the three-dimensional deployment of the wing during flight behaviors. Here, we use […]
The vortex wake of the hawkmoth, Manduca sexta Simulation and Reynolds number effects
Tytell, E.D.; Ellington, C.P.: The vortex wake of the hawkmoth, Manduca sexta: Simulation and Reynolds number effects The vortex wake structure of the hawkmoth, Manduca sexta, was investigated using a vortex ring generator. Based on existing kinematic and morphological data, a piston and tube apparatus was constructed to produce circular vortex rings with the same […]
The predatory legs of Philonthus marginatus (Coleoptera,Staphylinidae) Functional morphology and tarsal ultrastructure
Betz, O.*; Mumm, R.: The predatory legs of Philonthus marginatus (Coleoptera,Staphylinidae): Functional morphology and tarsal ultrastructure Within the Coleoptera, no predatory legs have become known thus far. However, within the staphylinid genus Philonthus representatives of the subgenus Onychophilonthus are distinct from other subgenera by the structure of their prolegs: both sexes have elongated coxae and […]
The impact of mitochondial thermal sensitivity on the swimming capacity of Arctic charr
BOLDUC, M.*; BLIER, P.U.; DUTIL, J.-D.: The impact of mitochondial thermal sensitivity on the swimming capacity of Arctic charr The swimming performance of fish lies on there capacity to convert chemical energy into mechanical energy, trough the contraction of axial muscle. During sustained swimming, ATP required for contraction is mostly supplied by mitochondrial metabolism. Oxygen […]
The effect of surface grades on the joint kinematics of quail during running
Heitmann, D.M.*; Scheunemann, T.L.; Carello, C.A.: The effect of surface grades on the joint kinematics of quail during running Locomotion is a major component to most animals� daily energy budgets. Button Quail (Coturnix chinensis) are ground foragers and therefore spend a predominant amount of time walking and running. However, little is known about how surface […]
The development of radialized and twinned gastropod embryos and its implication for spiralian development
Edsinger-Gonzales, E.*; van der Zee, M.; Dictus, W.J.A.G.; van den Biggelaar, J.A.M.: The development of radialized and twinned gastropod embryos and its implication for spiralian development Establishment of the adult body plan in molluscs requires induction by the blastomere 3D during embryogenesis. To understand 3D’s developmental function, we interfered with its specification in the gastropod, […]
The degree of crowding and its effect on the nesting behavior in the green turtle Chelonia mydas in Oman
ALKINDI, A.Y.A.; MAHMOUD, I.Y.; AL-GHEILANI, H.M.H.; AL-HABSI, A.A.; ALKIYUMI, A.A.; KHAN, H.*: The degree of crowding and its effect on the nesting behavior in the green turtle Chelonia mydas in Oman. The nesting behavior of the green turtle, Chelonia mydas was observed during high population density period (June-October) and low population density period (Nov-May) in […]
