Meeting Abstract 27-5  Saturday, Jan. 4 14:30 – 14:45  Activin/Nodal signaling is required for establishing the dorsal-ventral axis in Capitella teleta LANZA, AR*; SEAVER, EC; Whitney Laboratory for Marine Bioscience, University of Florida alexislanza@gmail.com TGF-beta superfamily signaling regulates a variety of developmental processes and has a conserved role in patterning the dorsal-ventral body axis. Within this signaling […]

Demes, B.*; Chiu, J.; Truong, C.; Qin, Y.; Larson, S.: The role of the primate fibula in weight-bearing of the leg Among mammals, primates have relatively robust fibulae. We investigated the role of the primate fibula in weight-bearing in an in vitro study of the deformation of the two leg bones in a chimpanzee, baboon […]

DUDEK, D.M.*; FULL, R.J.: Spring-like behavior of the legs of running insects The dynamics of many terrestrial organisms during running are similar to those of a bouncing spring-mass system. This observation has led to the search for spring-like behavior in the tendons of mammals. The dynamics of running cockroaches have been modeled as a spring-mass […]

Meijer, K*; Libby, T.M.; Full, R.J.: Passive stability provided by the musculo-skeletal properties of an insect leg. Cockroaches have an amazing ability to run over rough terrain. It has been hypothesized that their ability to perform stable locomotion in unstructured environments is facilitated by the mechanical properties of their muscles and exoskeleton. To investigate the […]

COX, D.E.*; BERTRAM, J.E.A.: Hypothesis testing as a lab exercise: a simple walking study This paper describes a laboratory exercise designed to provide students with experience testing a hypothesis by systematically isolating and controlling determinant variables. The study involves the analysis of walking and is performed by the students on a subject from within their […]
