The physiological basis of dishonest signals of strength in males of the fiddler crab Uca vomeris
Meeting Abstract 60.2 Thursday, Jan. 6 The physiological basis of dishonest signals of strength in males of the fiddler crab Uca vomeris. BYWATER, CL*; WHITE, C; WILSON, RS; The University of Queensland; The University of Queensland; The University of Queensland c.bywater@uq.edu.au Unreliable signals of weapon strength (signals that are poor indicators of strength) are considered problematic for […]
The dynamics of physiology-trait relationships implications for honest signal theory
Meeting Abstract 60.1 Thursday, Jan. 6 The dynamics of physiology-trait relationships: implications for honest signal theory SAFRAN, Rebecca J.; University of Colorado, Boulder rebecca.safran@colorado.edu An implicit assumption underlying several models within current sexual selection theory is that the physiological costs of sexual signals are static or fixed. In particular, the handicap and good genes indicator models of […]
Diving in soccer When does it pay to be dishonest
Meeting Abstract 60.5 Thursday, Jan. 6 Diving in soccer: When does it pay to be dishonest? DAVID, GK; WILSON, RS*; ORTIZ-BARRIENTOS, D; The University of Queensland; The University of Queensland; The University of Queensland r.wilson@uq.edu.au Deception is a highly controversial topic in animal communication. Many models attempt to explain how deceptive signalling persists in natural systems as […]
Call timing in the treefrog Dendropsophus ebraccatus the role of the aggressive call
Meeting Abstract 60.4 Thursday, Jan. 6 Call timing in the treefrog Dendropsophus ebraccatus: the role of the aggressive call REICHERT, M.S.; University of Missouri, Columbia msrgh9@mizzou.edu In frog choruses acoustic competition to attract mates can be severe. One striking form of acoustic competition in many species is the precise timing of calls relative to those of other […]
Analyzing the Costs and Benefits of Vocal Matching in Budgerigars a Test of the Password Hypothesis
Meeting Abstract 60.3 Thursday, Jan. 6 Analyzing the Costs and Benefits of Vocal Matching in Budgerigars: a Test of the Password Hypothesis YOUNG, A.M.*; WRIGHT, T.F.; New Mexico State University; New Mexico State University annay@nmsu.edu In budgerigars (Melopsittacus undulatus), vocal matching of an immigrant bird’s contact call to that of its new flock has been experimentally demonstrated, […]
Source Segregation Based on Spectral Cues A Mechanism for Hearing in Mixed-Species Frog Choruses
Meeting Abstract 59.1 Thursday, Jan. 6 Source Segregation Based on Spectral Cues: A Mechanism for Hearing in Mixed-Species Frog Choruses? BEE, M.A.*; NITYANANDA, V.; Univ. of Minnesota, Twin Cities; Univ. of Minnesota, Twin Cities mbee@umn.edu In humans, overlapping sounds can be perceptually separated and assigned to different sources in the environment based on differences in their acoustic […]
Morphological constraint and behavioral adaptation in the visual ecology of Megalagrion damselflies
Meeting Abstract 59.5 Thursday, Jan. 6 Morphological constraint and behavioral adaptation in the visual ecology of Megalagrion damselflies WALGUARNERY, J.W.*; BUTLER, M.A.; University of Hawaii, Manoa justinww@hawaii.edu The theory of sensory drive states that sensory receptors, sensory signals and signaling behaviors are functionally linked, and will therefore adapt jointly to maintain effective transmission of visual information under […]
Butterflies learn to like novel wing patterns, but learning that more is better is easier than learning that less is more
Meeting Abstract 59.3 Thursday, Jan. 6 Butterflies learn to like novel wing patterns, but learning that more is better is easier than learning that less is more WESTERMAN, E.L.*; MONTEIRO, A.; Yale University; Yale University erica.westerman@yale.edu Sexual ornaments and the preferences for these ornaments are gained and lost throughout evolutionary time. One factor that may influence the […]
Body Patterns of The Humboldt Squid Dosidicus gigas Diversity in a Uniform World
Meeting Abstract 59.6 Thursday, Jan. 6 Body Patterns of The Humboldt Squid Dosidicus gigas: Diversity in a Uniform World TRUEBLOOD, L.A.*; SEIBEL, B.A.; La Sierra University; University of Rhode Island lloyd.trueblood@lasierra.edu Cephalopods rapidly alter their external appearance, arguably better than any other group of organisms. Ethograms describe body appearance by separating body patterns into components of color, […]
