Meeting Abstract 10.4 Jan. 4 New Insights on the Evolution of Metazoan Photoreceptors PLACHETZKI, David C.*; OAKLEY, Todd H.; Univ. of California, Santa Barbara plachetzki@umail.ucsb.edu Duplication and divergence models are commonly invoked as a means of explaining evolutionary processes. While these concepts are usually applied to the gene and species levels, here we examine their role in […]

Mitochondrial genomics of sponges Implications for animal phylogeny and evolution
Meeting Abstract 10.1 Jan. 4 Mitochondrial genomics of sponges � Implications for animal phylogeny and evolution LAVROV, DV*; HAEN, KM; WANG, X; Iowa State University dlavrov@iastate.edu Mitochondrial DNA of bilaterian animals is typically a small, circular-mapping molecule that encodes 37 tightly packed genes. MtDNA of choanoflagellate Monosiga brevicollis, the closest unicellular out-group of animals, is four times […]

The Ventral Pouches of Lunge-Feeding Great Whales Play Central Dynamic Roles in Prey Capture and Filtration
Meeting Abstract 9.8 Jan. 4 The Ventral Pouches of Lunge-Feeding Great Whales Play Central Dynamic Roles in Prey Capture and Filtration KOT, B.W.; Univ. of California, Los Angeles bkot@ucla.edu Among the largest and most visible anatomical features of the great whales (rorquals; Mammalia: Balaenoptera) are their antero-ventral pleated pouches. These pouches are major components of the filter […]
The Ontogeny of Epiglottal Movement during Swallowing in Mammals
Meeting Abstract 9.7 Jan. 4 The Ontogeny of Epiglottal Movement during Swallowing in Mammals GERMAN, R.Z.*; CROMPTON, A.W.; THEXTON, A.J.; Johns Hopkins University; Harvard University; King’s College, London rz.german@jhmi.edu In mammalian feeding, the path that food takes crosses the airway. The function of the epiglottis, the superior cartilage of the larynx, during swallowing is debated and developmental […]

Extreme forces and jaw size variation in trap-jaw ants
Meeting Abstract 9.1 Jan. 4 Extreme forces and jaw size variation in trap-jaw ants SPAGNA, J.C.*; PATEK, S.N.; VAKIS, A.I.; SUAREZ, A.V.; University of Illinois, Urbana-Champaign; University of California, Berkeley; University of Illinois, Urbana-Champaign; University of Illinois, Urbana-Champaign jspagna@uiuc.edu The trap-jaw ant Odontomachus bauri (Formicidae: Ponerinae), produces the fastest self-propelled animal prey strikes known to science, averaging […]
Energy maximization strategies of two surface deposit-feeding gastropods
Meeting Abstract 9.0 Jan. 4 Energy maximization strategies of two surface deposit-feeding gastropods. MAHON, H. K. *; DAUER, D. M.; Old Dominion University; Old Dominion University hmahon@odu.edu Surface deposit-feeders rely on a poor food source; therefore, many have evolved strategies to increase sediment processing efficiency and to maximize net energy gain. Two strategies are patch selection and […]
Cracking the weevil behavioral plasticity of feeding as a function of prey hardness in the collared lizard
Meeting Abstract 9.3 Jan. 4 Cracking the weevil: behavioral plasticity of feeding as a function of prey hardness in the collared lizard HENNINGSEN, J.P.*; LAPPIN, A.K.; NISHIKAWA, K.C.; Northern Arizona University; Northern Arizona University; Northern Arizona University jhenning@nsm.umass.edu A number of studies have demonstrated that lizards modify their feeding behavior based upon prey characteristics. However, in their […]
