Are the swimming kinematics of blind cavefish (Astyanax mexicanus) adapted for active flow-sensing
Meeting Abstract P3.99 Wednesday, Jan. 6 Are the swimming kinematics of blind cavefish (Astyanax mexicanus) adapted for active flow-sensing? TAN, D*; PATTON, P; COOMBS, S; Bowling Green State University dstan@bgsu.edu When visual cues are poor or unavailable, animals often use a form of active sensing in which they produce their own signal energy to probe various features […]
Are modular characters labile in deep-sea bamboo corals
Meeting Abstract P3.43 Wednesday, Jan. 6 Are modular characters labile in deep-sea bamboo corals? DUEÑAS, L.F.*; SANCHEZ, J.A.; Universidad de los Andes, Bogotá, Colombia; Universidad de los Andes, Bogotá, Colombia lf.duenas161@uniandes.edu.co Character lability has been associated with morphological traits that appear multiple times in the tips of a given phylogeny. Labile traits could confer advantages for adaptation […]

Acute Stress Differentially Affects Myostatin Expression in Rainbow Trout, Oncorhynchus mykiss
Meeting Abstract P3.116 Wednesday, Jan. 6 Acute Stress Differentially Affects Myostatin Expression in Rainbow Trout, Oncorhynchus mykiss GALT, Nicholas*; BILLING, Samantha; BIGA, Peggy; North Dakota State University Nicholas.Galt@ndsu.edu Teleosts exhibit multiple myostatin (mstn) isoforms that are differentially regulated, suggesting that teleost mstn exhibits greater functional diversity. Mstn mRNA expression is found in a variety of tissues in […]
Acoustic resonance of the middle-ear in Alligator—implications for behavioral correlations
Meeting Abstract P3.77 Wednesday, Jan. 6 Acoustic resonance of the middle-ear in Alligator—implications for behavioral correlations. DUFEAU, DL*; WITMER, LM; Ohio University; Ohio University dd299405@ohio.edu The middle-ear space of crocodylians, and the pneumatic diverticula arising from it, are greatly expanded. This expanded sinus system invades the braincase to the extent that broad contralateral communications are created, resulting […]
