Meeting Abstract 47-1  Sunday, Jan. 5 10:30 – 10:45  Developing an automated pipeline for quantifying animal pigmentation using deep learning ALVARADO, SG*; KRUPAKAR, H; Queens College CUNY; GE Healthcare sebastian.alvarado@qc.cuny.edu http://www.alvaradolab.com Coloration is a salient trait across the animal kingdom that can allow an individual to become cryptic, conspicuous, or social. While some developmental patterns in pigmentation […]

Pizer, M.*; Wray, G.A.: The Evolution and Development of Left-Right Asymmetry in Echinoderms Echinoderms have a bilaterally symmetrical larva that becomes left-right asymmetric when adult structures begin to develop. These structures form primarily on the left side of the larva, eventually producing a pentaradially symmetrical adult. This unusual symmetry transition is one of the most […]

SEAVER, E.C.*; PAULSON, D.; IRVINE, S.Q.; MARTINDALE, M. Q.: Sequence and developmental expression of the engrailed gene in the polychaete Chaetopterus The number of times a segmented body plan has evolved in the metazoa is a currently debated issue. We are interested in understanding whether the annelids and arthropods share a common segmented ancestor and […]

deMaintenon, M.J.: Patterns of reproductive system development in the caenogastropods; systematic and evolutionary implications. The reproductive system is one of the most complex and variable of gastropod organ systems, and is often also the last organ system to develop. The level of anatomical variation of the reproductive system, coupled with its late development, renders it […]

Golenberg, E.M.: Floral Developmental Regulation and Sexual Lability in Spinach In dioecious, cultivated spinach, Spinacia oleracea, the presence or absence of reproductive organs is determined by organ primordia initiation rather than by degeneration of existing organ primordia as found in maize, sorrel, and campion. Male and female flowers differentiate morphologically early in floral morphogenesis (stage […]

NEDERBRAGT, A.J.*; DICTUS, W.J.A.G.; VANLOON, A.E.: Conserved Gene Networks in Development: The Engrailed and Dpp Homologues in Molluscan Shell Development During Drosophila development the engrailed/hedgehog/decapentaplegic gene network functions in setting up boundaries between different compartments, e.g. between anterior and posterior compartments in imaginal discs. Here, engrailed is expressed in cells on one side of the […]

FREEMAN, G.: A Developmental Basis for the Cambrian Explosion: Evidence from Extant Brachiopods Paleontological evidence indicates that a large number of new animal phyla, in addition to classes and orders within phyla, were first observed during the Cambrian. One possible basis for the genesis of new morphologies during this period may have been the ease […]

BOWKER, G.B.: The role of electrostatic forces in wind pollination Electrostatic forces are found throughout the terrestrial environment. Even when the weather is clear, a 100 Volt per meter (V/m) electric field is present between the atmosphere and ground. Consequently, organisms in electrical contact with the ground have negative charge induced on their surfaces. The […]
