Meeting Abstract 144.5 Monday, Jan. 7 The Effect of Phylogeny on Morphological Characteristics of the Skeleton in Pleuronectiformes BLACK, C.R.*; BERENDZEN, P.B.; Univ. of Northern Iowa; Univ. of Northern Iowa corinthi@uni.edu Pleuronectiformes, commonly known as flatfishes, are a highly specialized order of fishes displaying obvious asymmetrical morphology. When flatfish hatch, they are symmetrical. As development continues, one […]

Developmental influences on variation and asymmetry of the jaw
Meeting Abstract 144.3 Monday, Jan. 7 Developmental influences on variation and asymmetry of the jaw. FISH, JL*; DEPEW, MJ; MARCUCIO, RS; Univ. of California, San Francisco; Univ. of California, San Francisco; Univ. of California, San Francisco jennifer.fish@ucsf.edu Evo-devo as a discipline seeks to understand how variation is generated in a way that can influence evolution. Variation is […]
Developmental and genetic basis of a morphological novelty in East African cichlids
Meeting Abstract 144.4 Monday, Jan. 7 Developmental and genetic basis of a morphological novelty in East African cichlids CONCANNON, M.R.*; ALBERTSON, R.C.; UMass Amherst; UMass Amherst mrconcan@cns.umass.edu The production of novel phenotypic variation provides new traits on which selection can act and is often associated with expanded ecological opportunity. For this reason the developmental and genetic origins […]
Conservation of primaxial regionalization in the evolution of the snake body form
Meeting Abstract 144.6 Monday, Jan. 7 Conservation of primaxial regionalization in the evolution of the snake body form HEAD, J.J. *; POLLY, P.D.; University of Nebraska-Lincoln; Indiana University jhead2@unl.edu Shifts and reduction in Hox gene expression domains have been proposed as a primary mechanism in the evolution of the elongate, “deregionalized” axial skeleton of snakes and other […]
A novel transcriptional regulator, lbh, regulates cranial neural crest development and craniofacial evolution in East African cichlids
Meeting Abstract 144.2 Monday, Jan. 7 A novel transcriptional regulator, lbh, regulates cranial neural crest development and craniofacial evolution in East African cichlids POWDER, KE*; ALBERTSON, RC; Univ Massachusetts; Univ Massachusetts kepowder@bio.umass.edu East African cichlids exhibit a rapid and extensive adaptive radiation. One major axis of their divergence is trophic specialization, which is reflected in their craniofacial […]
