Meeting Abstract S9.3 Wednesday, Jan. 6 Paxβ: a lophotrochozoan gene family implicated in spiral cleavage SHANKLAND, M.*; SCHMERER, M.W.; NULL, R.W.; U. of Texas at Austin hastypig@mail.utexas.edu The Paxβ gene family is restricted to the bilaterian superphylum Lophotrochozoa. A conserved intron:exon organization suggests that the ancestral Paxβ arose by duplication and divergence of a Pax2/5/8 gene. This […]

D quadrant specification in a leech (Helobdella; sp) comparison with other spiralians
Meeting Abstract S9.8 Wednesday, Jan. 6 D quadrant specification in a leech (Helobdella; sp.): comparison with other spiralians WEISBLAT, D.A.*; CHO, S.J.; LYONS, D.C.; VALLéS, Y.; WANG, J.K.; Univ. of California, Berkeley; Univ. of California, Berkeley; Duke University; Univ. of California, Berkeley; Univ. of California, Berkeley weisblat@berkeley.edu In spiralian development, D quadrant specification is key to forming […]
Cracking the code of the spiralian quartets RNA segregation in Ilyanassa
Meeting Abstract S9.11 Wednesday, Jan. 6 Cracking the code of the spiralian quartets: RNA segregation in Ilyanassa LAMBERT, J D; Univ. of Rochester dlamber2@mail.rochester.edu In spiralian embryos, the animal-vegetal axis is divided into tiers of cells with similar developmental potentials. These tiers are quartets of micromeres that are born from the macromeres in the same cleavage cycle, […]
Cell and molecular mechanisms involved in the establishment of the D quadrant in the Gastropod, Crepidula fornicata
Meeting Abstract S9.2 Wednesday, Jan. 6 Cell and molecular mechanisms involved in the establishment of the D quadrant in the Gastropod, Crepidula fornicata HENRY, JJ*; PERRY, KJ; University of Illinois; University of Illinois j-henry4@illinois.edu In spiralian embryos cells of the D quadrant play a key role in establishing the dorsoventral axis and in organizing subsequent development of […]
Using intraspecific variation to assess the capacity for acclimation and adaptation of thermal tolerance in fish
Meeting Abstract S9.5 Friday, Jan. 7 Using intraspecific variation to assess the capacity for acclimation and adaptation of thermal tolerance in fish SCHULTE, P.M.*; DHILLON, R.S.; HEALY, T.M.; University of British Columbia pschulte@zoology.ubc.ca Understanding the extent to which organisms can acclimate or adapt to changes in environmental temperature is likely to be a critical component of our […]
Thermal genetic adaptation in the water flea Daphnia and its impact – an experimental evolution approach
Meeting Abstract S9.7 Friday, Jan. 7 Thermal genetic adaptation in the water flea Daphnia and its impact – an experimental evolution approach DE MEESTER, Luc*; STOKS, Robby; VAN DOORSLAER, Wendy; GEERTS, Aurora; ORSINI, Luisa; University of Leuven; University of Leuven; University of Leuven; University of Leuven; University of Leuven Luc.DeMeester@bio.kuleuven.be We present results on rapid genetic adaptation […]
The world is not flat defining the thermal landscapeagain
Meeting Abstract S9.1 Friday, Jan. 7 The world is not flat: defining the thermal landscape…again SEARS, Michael W.*; ANGILLETTA, Michael J.; Bryn Mawr College; Arizona State University msears@brynmawr.edu Although climates are rapidly changing on a global scale, these changes cannot easily be extrapolated to the local scales experienced by organisms. In fact, such generalizations might be quite […]
The role of evolutionary theory in predicting responses to environmental warming
Meeting Abstract S9.2 Friday, Jan. 7 The role of evolutionary theory in predicting responses to environmental warming ANGILLETTA, M. J.*; SEARS, M. W.; Arizona State Univ., Tempe; Bryn Mawr College, Bryn Mawr angilletta@asu.edu Because populations adapt to environmental changes, predicting the impacts of climate change requires a quantitative evolutionary theory. Both statistical and mechanistic models can help […]
Shrinking Islands in the Sky Trait- and Microclimate-based Forecasts of the Range Dynamics of Montane Species Under Climate Change
Meeting Abstract S9.10 Friday, Jan. 7 Shrinking Islands in the Sky? Trait- and Microclimate-based Forecasts of the Range Dynamics of Montane Species Under Climate Change KOZAK, Kenneth H; University of Minnesota kozak016@umn.edu Many of the species that inhabit montane biodiversity hotspots occur exclusively in high-elevation habitats. Consequently, montane biotas are thought to be particularly susceptible to anthropogenic […]
Physiological adaptation to climate change in a montane insect
Meeting Abstract S9.6 Friday, Jan. 7 Physiological adaptation to climate change in a montane insect DAHLHOFF, EP*; RANK, NE; Santa Clara University; Sonoma State University edahlhoff@scu.edu The willow beetle Chrysomela aeneicollis is an ideal model system for investigating physiological mechanisms by which climate change impacts natural systems. Beetles are found at high elevation in California’s Sierra Nevada, […]
