Sexual dimorphism in courtship and copulatory neuromuscular systems of Anolis lizards
Meeting Abstract 25.1 Friday, Jan. 4 Sexual dimorphism in courtship and copulatory neuromuscular systems of Anolis lizards JOHNSON, M. A.*; WADE, J.; Michigan State University; Michigan State University micheleajohnson@gmail.com To reproduce, many animals must perform both courtship and copulatory behavior. However, the neuromuscular systems that control these two types of behavior have rarely been investigated in the […]

Metabotropic Glutamate Signalling System in a Freshwater Sponge
Meeting Abstract 25.6 Friday, Jan. 4 Metabotropic Glutamate Signalling System in a Freshwater Sponge ELLIOTT, GRD*; LEYS, SP; University of Alberta; University of Alberta gelliott@ualberta.ca Ephydatia muelleri propagates contractions across the sponge body to expel waste or stagnant water. The entire behaviour consists of a peristaltic contraction of the incurrent canals that progresses to the excurrent canals, […]
