Meeting Abstract 122-7 Tuesday, Jan. 7 11:45 – 12:00 Treefrog egg-clutch biomechanics and their effect on embryo escape-hatching behavior GüELL, BA*; CALDWELL, MS; WARKENTIN, KM; Boston University; Gettysburg College; Boston University bguell@bu.edu https://brandonguell.wordpress.com/ Arboreal embryos of phyllomedusid treefrogs hatch prematurely to escape snake predation, cued by low frequency vibrations in their egg clutches. Escape success varies between […]

Evaluating the use of hydrogel stabilization for reinforcing nervous tissues before iodine diffusion TAYLOR, MS*; O’BRIEN, HD; GIGNAC, PM; Oklahoma State University Center for Health Sciences; Oklahoma State University Center for Health Sciences; Oklahoma State University Center for Health Sciences matthew.s.taylor@okstate.edu As a […]
On the Nonlinear Mechanics of the Honeybee Thorax
Meeting Abstract 122-4 Tuesday, Jan. 7 11:00 – 11:15 On the Nonlinear Mechanics of the Honeybee Thorax JANKAUSKI, MA; Montana State University mark.jankauski@montana.edu http://mjankauski.com The thorax (or thorax-wing assembly) of flying insects is widely believed to behave as a resonant mechanical oscillator. Thorax resonance is likely critical to the function of asynchronous muscles and may reduce the […]
Convergent evolution of ultra-black butterfly scales
Meeting Abstract 122-6 Tuesday, Jan. 7 11:30 – 11:45 Convergent evolution of ultra-black butterfly scales DAVIS, AL*; NIJHOUT, HF; JOHNSEN, S; Duke University al.davis@duke.edu Understanding animal coloration is important for investigating sexual selection, speciation, and animal signaling. Despite a growing number of papers investigating structural colors, the role of nanostructures in creating black color patches has largely […]
At the nexus of iodine staining duration and specimen size repeated-measures study to improve visualization of vertebrate soft-tissue anatomy using diceCT imaging
Meeting Abstract 122-1 Tuesday, Jan. 7 10:15 – 10:30 At the nexus of iodine staining duration and specimen size: repeated-measures study to improve visualization of vertebrate soft-tissue anatomy using diceCT imaging GIGNAC, PM*; KLEY, NJ; Oklahoma State University Center for Health Sciences; Stony Brook University paul.gignac@okstate.edu http://www.dicect.com Diffusible iodine-based contrast-enhanced computed tomography (diceCT) facilitates three-dimensional imaging of […]
Adipose tissue in diving animals measuring the potential for gas exchange
Meeting Abstract 122-3 Tuesday, Jan. 7 10:45 – 11:00 Adipose tissue in diving animals: measuring the potential for gas exchange SMITH, MG*; WESTGATE, AJ; KOOPMAN, HN; Harvard University; UNC Wilmington; UNC Wilmington mollygablersmith@gmail.com Diving tetrapods are a biologically diverse group; however, they are all under similar constraints: oxygen limitation and increased hydrostatic pressure at depth. Adipose tissue […]

Spider vasa is required for early embryogenesis but not for germline specification
Meeting Abstract 122.3 Monday, Jan. 7 Spider vasa is required for early embryogenesis but not for germline specification SCHWAGER, E.E.*; MENG, Y; EXTAVOUR, C.G.; Harvard University; Harvard University; Harvard University eschwager@oeb.harvard.edu Metazoans specify their germline either early in development by maternally transmitted cytoplasmic factors (inheritance), or later in development by signaling factors from neighboring tissues (induction). The […]
Notch signaling during neural development in the annelid Capitella teleta
Meeting Abstract 122.1 Monday, Jan. 7 Notch signaling during neural development in the annelid Capitella teleta TOLCHIN, S; MEYER, NP*; Clark Univ. nmeyer@clarku.edu Central nervous system development begins with fate specification of neural precursor cells, which generate the brain and nerve cord. Comparisons between vertebrates and arthropods have provided important insights into neural development, but studies in […]
