MicroRNA regulation of alternative phenotypic development of the annual killifish, Austrofundulus limnaeus
Meeting Abstract P2.16 Saturday, Jan. 5 MicroRNA regulation of alternative phenotypic development of the annual killifish, Austrofundulus limnaeus ROMNEY, AMIE*; PODRABSKY, JASON; Portland State University; Portland State University arom2@pdx.edu The annual killifish, Austrofundulus limnaeus, is capable of severe metabolic depression during embryonic development as a facultative phenotype termed diapause. However, a small percentage of genetically related individuals […]
Metamorphosis in the Demosponge Amphimedon queenslandica
Meeting Abstract P2.88 Saturday, Jan. 5 Metamorphosis in the Demosponge Amphimedon queenslandica NAKANISHI, N*; SOGABE, S; DEGNAN, B; University of Queensland n.nakanishi@uq.edu.au We examined the pattern of cell proliferation, differentiation, migration and death during metamophosis from a free-swimming larva into a juvenile in the demosponge Amphimedon queenslandica. Our experimental approach combined immunohistochemistry (e.g. anti-phosphorylated histone H3), dye […]

Macroevolutionary diversity of amniote limb proportions is congruent with predictions from developmental interactions
Meeting Abstract P2.81 Saturday, Jan. 5 Macroevolutionary diversity of amniote limb proportions is congruent with predictions from developmental interactions YOUNG, N.M.; University of California, San Francisco nathan.m.young@gmail.com Mammals, birds, and reptiles exhibit remarkable diversity in limb proportions. These evolved differences are thought to principally reflect selection on variation in fetal and postnatal segmental growth. However, early conserved […]
Looking at invisibility anti-reflective structures and strategies in hyperiid amphipods
Meeting Abstract P2.55 Saturday, Jan. 5 Looking at invisibility: anti-reflective structures and strategies in hyperiid amphipods BAGGE, L.E.*; JOHNSEN, S.; Duke University; Duke University laura.bagge@duke.edu Transparency is a common camouflage strategy for animals inhabiting marine pelagic environments. Transparent species are almost perfectly invisible when viewed under ambient light conditions in the mesopelagic zone; however, at shallower depths, […]
Lateralization in aggressive behavior and brain morphology in the green anole lizard (Anolis carolinensis)
Meeting Abstract P2.185 Saturday, Jan. 5 Lateralization in aggressive behavior and brain morphology in the green anole lizard (Anolis carolinensis) PATTON, M.S.*; MEGAHED, T.; JOHNSON, M.A.; Trinity University mpatton@trinity.edu Lizards are an ideal organism for studies of laterality in brain and behavior due to the lizard visual system; each eye is located on opposing sides of the […]
