Meeting Abstract S9-1.7  Monday, Jan. 7  Physiological response and local adaptation of marine invertebrates to natural variation in the ocean acidification seascape HOFMANN, Gretchen/E; UC Santa Barbara hofmann@lifesci.ucsb.edu Understanding how marine ecosystems will respond to future anthropogenic change – e.g., ocean warming and ocean acidification – is a critical priority for the research community. Central to this […]

Meeting Abstract S9-1.2  Monday, Jan. 7  Interactions between temperature and oxygen and the evolution of body size in invertebrates KLOK, CJ*; HARRISON, JF; Arizona State University; Arizona State University cjklok@asu.edu Temperature is a key factor that affects the rates of growth and development in animals, which ultimately determine body size. While not universal, a widely documented and […]

Meeting Abstract S9-1.4  Monday, Jan. 7  Impacts of warming and ocean acidification on growth of larval and juvenile sea urchins – from the poles to the tropics BYRNE, M; Univ. of Sydney, Australia mbyrne@anatomy.usyd.edu.au The Temperature Size Rule states that temperature increases development rates of ectotherms faster than growth rates, resulting in smaller body sizes at life […]

Meeting Abstract S9-1.5  Monday, Jan. 7  Expect the unexpected: vignettes from multistressor studies that explore global change responses of a range of marine and freshwater organisms. TODGHAM, AE*; STILLMAN, JH TBA

Meeting Abstract S9-1.6  Monday, Jan. 7  Energy homeostasis as a tool to integrate the effects of multiple stressors in animals SOKOLOVA, Inna; University of North Carolina at Charlotte isokolov@uncc.edu Energy balance plays a key role in survival and stress tolerance of all organisms due to the need to balance energy demand with sufficient energy supply for survival. […]

Meeting Abstract S9-1.1  Monday, Jan. 7  Cross-tolerance and cross-talk in the cold: relationships between low temperature and other stressors in insects SINCLAIR, BJ*; MACMILLAN, HA; FERGUSON, LV; SALEHIPOUR, G; University of Western Ontario bsincla7@uwo.ca Insects are the most successful group of terrestrial animals, having overcome the challenges of variable temperatures and desiccating conditions. Overwintering temperate, polar and […]

Meeting Abstract S9-1.3  Monday, Jan. 7  Body temperatures along altitudinal and latitudinal gradients: interactions between phenotypes and multiple environmental stressors BUCKLEY, Lauren B.; Univ. of North Carolina, Chapel Hill buckley@bio.unc.edu The divergence between body and air temperatures is central to patterns of thermal stress associated with climate change. We use biophysical models to estimate body temperatures as […]

Meeting Abstract S8-2.1  Sunday, Jan. 6  “Don’t judge a book by its cover: Discovering two new Verongida genera (Class Demospongiae, Porifera)” DIAZ, M.C.*; THACKER, R.W.T; REDMOND, N.; COLLINS, A.G; Museo Marino, NE, Venezuela; U. Alabama at Birmingham, USA; NMNH, Smithsonian Institution, USA; NMNH, Smithsonian Institution, USA taxochica@gmail.com Integrating morphological and molecular data is crucial when morphological characters […]

Meeting Abstract S8-2.2  Sunday, Jan. 6  The origin of freshwater sponges: when, where, and why? LAVROV, Dennis; Iowa State University dlavrov@iastate.edu All animal phyla originated in the sea but only a few of them have colonized freshwater. The transition to limnic ecosystems required multiple adaptations to cope with highly variable temperatures, salinities, oxygen concentrations, and other parameters […]

Meeting Abstract S8-2.3  Sunday, Jan. 6  Phylogenomics of non-bilaterian animals: pitfalls and challenges WOERHEIDE, G; Ludwig-Maximilians-Universitaet Muenchen woerheide@lmu.de Deep-level metazoan relationships have long been controversial issues. Especially a well resolved and supported phylogeny of non-bilaterian animals is needed to provide a robust framework for reconstructing early metazoan evolution. Expanding molecular (phylogenomic) datasets are increasingly being used to […]
