Sexual dimorphism in courtship and copulatory neuromuscular systems of Anolis lizards
Meeting Abstract 25.1 Friday, Jan. 4 Sexual dimorphism in courtship and copulatory neuromuscular systems of Anolis lizards JOHNSON, M. A.*; WADE, J.; Michigan State University; Michigan State University micheleajohnson@gmail.com To reproduce, many animals must perform both courtship and copulatory behavior. However, the neuromuscular systems that control these two types of behavior have rarely been investigated in the […]
Rapid modification of preoptic area egr-1 and vasotocin mRNA by social opportunity
Meeting Abstract 25.3 Friday, Jan. 4 Rapid modification of preoptic area egr-1 and vasotocin mRNA by social opportunity BURMEISTER, SS*; LEBONVILLE, CML; FERNALD, RD; Univ. of North Carolina; Univ. of North Carolina; Stanford Univ. sburmeister@unc.edu In the cichlid fish Astatotilapia burtoni, male-male interactions determine social status which, in turn, has a number of physiological and behavioral consequences. […]
Metabotropic Glutamate Signalling System in a Freshwater Sponge
Meeting Abstract 25.6 Friday, Jan. 4 Metabotropic Glutamate Signalling System in a Freshwater Sponge ELLIOTT, GRD*; LEYS, SP; University of Alberta; University of Alberta gelliott@ualberta.ca Ephydatia muelleri propagates contractions across the sponge body to expel waste or stagnant water. The entire behaviour consists of a peristaltic contraction of the incurrent canals that progresses to the excurrent canals, […]

The optics and evolution of scallop eyes
Meeting Abstract 25.10 Monday, Jan. 5 The optics and evolution of scallop eyes SPEISER, D.I.*; JOHNSEN, S.; Duke Univ.; Duke Univ. dis4@duke.edu Scallops can possess upwards of one hundred eyes along their valve margins. These eyes contain two distinct retinas and form images by the reflection of light off a concave spherical mirror. It is thought that […]
Stable isotope analysis a quantitative approach to linking diet and morphological specialization in mantis shrimp
Meeting Abstract 25.7 Monday, Jan. 5 Stable isotope analysis: a quantitative approach to linking diet and morphological specialization in mantis shrimp DEVRIES, M.S.; Univ. of California, Berkeley msdevries@berkeley.edu Many animals have specialized feeding structures used to consume specific prey types. Mantis shrimp provide an excellent system to study the relationship between morphological and diet specialization, because their […]
Resonant Feathers Enable Sound Production in Machaeropterus deliciosus (Aves)
Meeting Abstract 25.2 Monday, Jan. 5 Resonant Feathers Enable Sound Production in Machaeropterus deliciosus (Aves) BOSTWICK, Kimberly/S*; ELIAS, Damian; MASON, Andrew; MONTEALEGRE-Z, Fernando; Cornell University; University of British Columbia; University of Toronto Scarborough; University of Bristol ksb6@cornell.edu Male Club-winged manakins produce a unique, sustained, tonal sonation while perched during courtship. The sound is hypothesized to result from […]
