Meeting Abstract 130.4  Tuesday, Jan. 7 14:15  The effect of parity (oviparous vs. viviparous) on morphological evolution among Phrynosomatidae OUFIERO, C.E.*; GARTNER, G.E.A.; Towson University; Museum of Comparative Zoology coufiero@towson.edu A major transition in life-history evolution is the shift from egg-laying (oviparity) to live birth (viviparity). Viviparity has evolved independently multiple times among vertebrate taxa, with an […]

Meeting Abstract 130.8  Tuesday, Jan. 7 15:15  Reconciling morphology, molecules, and species diversity with phoronid phylogenetic relationships. SANTAGATA, S.; Long Island University-Post scott.santagata@gmail.com Phoronids are tubiculous marine invertebrates closely related to brachiopods. Previous phylogenetic work by Santagata and Cohen (2009) found only weak congruence between the morphological and molecular based analyses. Here, I present an improved molecular […]
