Meeting Abstract P3.41  Wednesday, Jan. 6  Phylogeny and nematocysts of the invasive species Cordylophora caspia WOLLSCHLAGER, J. M.; Ohio State University, Columbus Ohio Wollschlager.2@buckeyemail.osu.edu The Ponto-Caspian invasive hydrozoan Cordylophora caspia contains four genetic lineages. Nonetheless, the species has not been formally split, nor has there been a clear pattern of use for older names like Cordylophora lacustris. […]

Meeting Abstract P3.64  Wednesday, Jan. 6  Ozone-induced gene dysregulation in rat and Tokay gecko lung cells: A comparative approach YAMASHITA, R.*; SAITO-REIS, C.; TAKAI, J.; DOHM, M.R.; Chaminade University, Honolulu mdohm@chaminade.edu Ground-level ozone (O3), a significant oxidant component of urban air pollution, is linked to excess lung disease and morbidity in humans. Effects on wildlife are not […]

Meeting Abstract P3.57  Wednesday, Jan. 6  Oxidative stress in response to cold acclimation in threespine sticklebacks (Gasterosteus aculeatus) KAMMER, A.R.*; O’BRIEN, K.M.; University of Alaska Fairbanks; University of Alaska Fairbanks arkammer@alaska.edu We sought to quantify levels of oxidative stress during cold acclimation and to determine if increases in reactive oxygen species (ROS) might be responsible for stimulating […]

Meeting Abstract P3.71  Wednesday, Jan. 6  Origin and development of the hypertrophied cypriniform pharyngeal jaws SOU, E*; HERNANDEZ, LP; George Washington University; George Washington University emilys525@gmail.com Significant hypertrophy of the pharyngeal jaws characterizes most cypriniforms. Here we use both a phylogenetic approach, as well as an ontogenetic analysis of growth to examine the origin and evolution of […]
