Meeting Abstract 45.5  Saturday, Jan. 5  How similar are regeneration and fission in naidine annelids? BELY, A.E.**; ZATTARA, E.; BURTON, P.M.; SIKES, J.M.; NYBERG, K.G.; Univ. of Maryland, College Park abely@umd.edu Many animals with high regeneration potential can also reproduce by asexual agametic reproduction (eg, fission, budding). In groups such as annelids, both phylogenetic and developmental evidence […]

Meeting Abstract 45.2  Saturday, Jan. 5  Fish fingers and the origin of limbs: A compendium of recent progress DAVIS, M.C.; Kennesaw State University mdavi144@kennesaw.edu Recent comparative developmental studies and paleontological discoveries have provided us with exciting new insights into how the unique attributes of the tetrapod limb, namely digits, may have evolved. Developmental studies in the basal […]

Meeting Abstract 45.1  Saturday, Jan. 5  Appendage Regeneration in Animals: a framework for future research MAGINNIS, TL; The University of Montana, Missoula taramaginnis@austin.rr.com Many organisms have the ability to shed an appendage (autotomy) to escape a predator or fouled molting event. Despite its immediate advantage on survivorship, autotomy can have important consequences for locomotion, foraging, survivorship, and/or […]

Meeting Abstract 45.1  Monday, Jan. 5  Visual spectral sensitivity underlying orientation and rhythmic behaviors in the talitrid amphipod Talorchestia longicornis COHEN, Jonathan/H*; FORWARD, JR., Richard/B; CRONIN, Thomas/W; Eckerd College; Duke University Marine Laboratory; University of Maryland, Baltimore County cohenjh@eckerd.edu Talorchestia longicornis is a supratidal talitrid amphipod inhabiting coastal and estuarine sandy beaches along the Atlantic coast of […]

Meeting Abstract 45.3  Monday, Jan. 5  Reconciling Open- and Closed-Loop Experiments in Sensorimotor Control of Drosophila ROTH, E.*; REISER, M.B.; COWAN, N.J.; Johns Hopkins University; Howard Hughes Medical Institute; Johns Hopkins University eatai@jhu.edu In optomotor yaw regulation experiments, a rigidly tethered fly (Drosophila) modulates yaw torque to frontally fixate a moving vertical stripe. In closed-loop experiments, the […]

A.; Eastern Oregon University; Eastern Oregon University; Eastern Oregon University shaun.cain@eou.edu How the brain of animals make decisions based on conflicting sensory information is an important component of the nervous control of behavior. […]

Meeting Abstract 45.4  Monday, Jan. 5  Changes in synaptic connections between mechanosensory neurons in leeches mediates species-specific behavior patterns. BALTZLEY, MJ*; GAUDRY, Q; KRISTAN, JR., WB; St. Mary’s College of Maryland; University of California, San Diego; University of California, San Diego mjbaltzley@smcm.edu We characterized the behavioral responses of two species of leeches, Hirudo verbana and Erpobdella obscura, […]

Meeting Abstract 45.2  Monday, Jan. 5  Behavioral context modulates the loss of local feedback sensors on flight in the moth Manduca sexta. WILLIS, Mark/A.*; AVONDET, Jennifer/L.; Case Western Reserve University; Case Western Reserve University maw27@case.edu Information from local feedback sensors is known to have profound effects on flight motor patterns, and has been shown to affect maneuvering […]
