Influence of energy expenditures on ultradian rhythms of activity and metabolic rate in root vole
Meeting Abstract P3.131 Jan. 6 Influence of energy expenditures on ultradian rhythms of activity and metabolic rate in root vole GEBCZYNSKI, A.K.; University of Bialystok, Poland andgebcz@uwb.edu.pl Microtine species are known to have an ultradian pattern of activity. Earlier study suggested that period of activity oscillations decreased after magnification of the average energy expenditure. Moreover, the lack […]
Inferring ancestral function in morphologically redundant complex traits
Meeting Abstract P3.33 Jan. 6 Inferring ancestral function in morphologically redundant complex traits BANBURY, B.L.*; ALFARO, M.E.; Washington State University; Washington State University bbanbury@wsu.edu Ancestral state reconstruction methods are commonly used by biologists interested in inferring patterns of evolution in functional traits. However, functional traits typically possess two relevant levels of design: the emergent functional property itself […]
Inferring Binocular Visual Field Overlap in Non-Avian Dinosaurs Based on an Extant Avian Scaling Model
Meeting Abstract P3.44 Jan. 6 Inferring Binocular Visual Field Overlap in Non-Avian Dinosaurs Based on an Extant Avian Scaling Model HALL, M.I.*; HEESY, C.P.; CARRANO, M.T.; Midwestern University; Midwestern University; Smithsonian Institution margaretihall@yahoo.com The primary sensory mode of prey location by predatory theropod dinosaurs is the subject of continued speculation. The potential development of stereoscopically based depth […]
Increased mite parasitism as a cost of testosterone in male Striped Plateau Lizards, Sceloporus virgatus
Meeting Abstract P3.129 Jan. 6 Increased mite parasitism as a cost of testosterone in male Striped Plateau Lizards, Sceloporus virgatus COX, Robert M*; JOHN-ALDER, Henry B; Ohio State University; Rutgers University cox.541@osu.edu The sex steroid testosterone (T) coordinates the seasonal and sex-specific expression of numerous physiological, behavioral, and morphological traits that contribute to male reproductive success. However, […]
INFORMATION ENCODED IN THE EARLY ONTOGENETIC SHELLS OF PLANKTONIC GASTROPOD LARVAE KELLETIA KELLETII AS A MODEL FOR PALEOBIOLOGICAL INFERENCE
Meeting Abstract P3.11 Jan. 6 INFORMATION ENCODED IN THE EARLY ONTOGENETIC SHELLS OF PLANKTONIC GASTROPOD LARVAE: KELLETIA KELLETII AS A MODEL FOR PALEOBIOLOGICAL INFERENCE VENDETTI, Jann; Univ. of California, Berkeley jannv@berkeley.edu The developmental mode of extant and extinct gastropod taxa can be inferred from morphological characters of the gastropod larval shell. Planktotrophy, lecithotrophy, and direct modes of […]
Hydrodynamic stability of swimming turtles correlations with shell shape
Meeting Abstract P3.62 Jan. 6 Hydrodynamic stability of swimming turtles: correlations with shell shape? RIVERA, G.*; BLOB, R. W.; Clemson University grivera@clemson.edu Hydrodynamic stability in swimming animals can be defined as the ability to resist recoil movements of the body and maintain a given trajectory. Morphological features, such as body depth and rigidity, have been suggested to […]
Hold Em or Fold Em Hindlimb Flight Posture in Birds
Meeting Abstract P3.51 Jan. 6 Hold �Em or Fold �Em? Hindlimb Flight Posture in Birds SHEPARD, L.S.*; MEYERS, R.A.; Weber State University, Ogden, UT; Weber State University, Ogden, UT rmeyers@weber.edu While flying, birds hold their legs in one of two different ways: either in an extended position with the legs trailing behind the body or in a […]
Hindlimb flexor muscle strain during swimming in the toad, Bufo marinus
Meeting Abstract P3.68 Jan. 6 Hindlimb flexor muscle strain during swimming in the toad, Bufo marinus MILLER, Dery*; GILLIS, Gary; Mount Holyoke College; Mount Holyoke College ggillis@mtholyoke.edu A number of electromyographic (EMG) analyses of limb function during anuran swimming have shown that major hindlimb extensor muscles are activated nearly simultaneously once per locomotor cycle. In contrast, recent […]
