Evolution of Complex Life Cycles Is Performance Constrained across Metamorphosis
Meeting Abstract 11-1 Monday, Jan. 4 08:00 Evolution of Complex Life Cycles: Is Performance Constrained across Metamorphosis? FREDA, P.J.*; MORGAN, T.J.; RAGLAND, G.J.; Kansas State University; Kansas State University; Kansas State University pfreda@ksu.edu Organisms are not static over their lifetimes. Characteristic change as the genome unfolds across ontogeny. This change can be extreme, especially over the course […]
Development of a non-feeding trochophore-like pilidium
Meeting Abstract 11-3 Monday, Jan. 4 08:30 Development of a non-feeding trochophore-like pilidium HUNT, M*; MASLAKOVA, SA; Oregon Institute of Marine Biology, University of Oregon mhunt@uoregon.edu The pilidium larva is an idiosyncrasy defining one nemertean clade, the Pilidiophora. It forms the juvenile from a series of isolated rudiments called imaginal discs, then erupts through and eats the […]
