Trimethylamine oxide accumulation as a function of depth in Hawaiian midwater fishes
Meeting Abstract 49-1 Tuesday, Jan. 5 10:00 Trimethylamine oxide accumulation as a function of depth in Hawaiian midwater fishes BOCKUS, A.B.*; SEIBEL, B.A.; University of Rhode Island; University of Rhode Island abockus@my.uri.edu Trimethylamine oxide (TMAO) is a common osmolyte and counteracting solute. It is believed to combat the stress induced by hydrostatic pressure as some deep-sea animals […]
The endoplasmic reticulum chaperones control canalization of animal development under environmental stress
Meeting Abstract 49-7 Tuesday, Jan. 5 11:30 The endoplasmic reticulum chaperones control canalization of animal development under environmental stress SATO, A; Ochanomizu University sato.atsuko@ocha.ac.jp http://www-p.cc.ocha.ac.jp/bio-atuko/ Canalization is a result of intrinsic developmental buffering that ensures phenotypic robustness under genetic variation and environmental perturbation. As a consequence, animal phenotypes are remarkably consistent within a species under a wide […]

Small RNA gene expression and localization in anoxia tolerant annual killifish embryos
Meeting Abstract 49-5 Tuesday, Jan. 5 11:00 Small RNA gene expression and localization in anoxia tolerant annual killifish embryos RIGGS, C.L.*; PODRABSKY, J.E.; Portland State University; Portland State University rclaire@pdx.edu Embryos of the annual killifish Austrofundulus limnaeus can live without oxygen for a matter of hours, or over 100 days, depending on their developmental age. Studying the […]
Gene expression during development and diapause in a vertebrate extremophile
Meeting Abstract 49-4 Tuesday, Jan. 5 10:45 Gene expression during development and diapause in a vertebrate extremophile ROMNEY, A. L. *; PODRABSKY, J. E.; Portland State University; Portland State University arom2@pdx.edu http://www.pdx.edu/podrabsky-lab/ The annual killifish, Austrofundulus limnaeus, survives in harsh and unpredictable environments through their ability to enter into embryonic diapause. Diapause is a pre-programmed exit from […]
