Meeting Abstract 75.3 Monday, Jan. 6 08:30 The consequences of thermal stress on early embryonic development: from cells to the whole-organism LOCKWOOD, B.L.*; MONTOOTH, K.L.; Indiana University; Indiana University bllockwo@indiana.edu For ectothermic organisms like Drosophila, changes in environmental temperature alter cellular processes. During early development, a rapid series of mitotic divisions bring an embryo from having a […]

Electro-dynamic suction pumping in Ascidian Hearts
Meeting Abstract 74.7 Monday, Jan. 6 09:30 Electro-dynamic suction pumping in Ascidian Hearts BAIRD, A. J.*; MILLER, L. A.; University of Carolina, Chapel Hill abaird@live.unc.edu Dynamic suction pumping is characterized by a bidirectional elastic wave and a non-linear frequency flow relationship. This pumping mechanism has been proposed as the driving mechanism for the vertebrate embryonic heart at […]
