Plasticity in Hatching in Response to Predators and Individual Variation in Duration, Frequency, and Seasons of Brooding in the Barnacle Balanus glandula
Meeting Abstract 87.5 Sunday, Jan. 6 Plasticity in Hatching in Response to Predators and Individual Variation in Duration, Frequency, and Seasons of Brooding in the Barnacle Balanus glandula STRATHMANN, R.R.*; BRANSCOMB, E.S.; VEDDER, K.; Univ. of Washington, Friday Harbor rrstrath@u.washington.edu Hatching in response to predation reduces a potential cost of holding larvae until conditions in the plankton […]
Molecular and Morphological Description of Stomatopod Larvae
Meeting Abstract 87.1 Sunday, Jan. 6 Molecular and Morphological Description of Stomatopod Larvae FELLER, KD*; PORTER, ML; CRONIN, TW; UMBC; University of South Dakota; UMBC kfeller1@umbc.edu The stomatopod larval phase is adapted for survival in the pelagic environment. Larvae have thus evolved an overall morphology that is separate from the adult, making them difficult to identify since […]
Egg size and exogenous food level interact to affect larval growth in tropical Echinometra spp sea urchins
Meeting Abstract 87.2 Sunday, Jan. 6 Egg size and exogenous food level interact to affect larval growth in tropical Echinometra spp. sea urchins MCALISTER, J/S*; MORAN, A/L; College of the Holy Cross; Clemson University jmcalist@holycross.edu Planktotrophic larvae of marine invertebrates develop and grow by utilizing energy and materials from a combination of maternally-supplied endogenous egg reserves and […]
The Molecular Basis of the Leech O-P Equivalence Group and the Evovability of Metazoan Patterning Mechanisms
Meeting Abstract 87.1 Monday, Jan. 6 10:15 The Molecular Basis of the Leech O-P Equivalence Group and the Evovability of Metazoan Patterning Mechanisms KUO, D.-H.; National Taiwan University, Taipei, Taiwan dhkuo@ntu.edu.tw The O-P equivalence group is a classical experimental paradigm in leech embryology. In leeches and their clitellate annelid allies, embryogenesis largely follows a stereotyped pattern of […]
Notch signaling may have evolved to control cellular differentiation and growth during development of metazoan animals
Meeting Abstract 87.3 Monday, Jan. 6 10:45 Notch signaling may have evolved to control cellular differentiation and growth during development of metazoan animals LAYDEN, MJ*; MARTINDALE, MQ; University of Florida layden@whitney.ufl.edu The emergence of multicellular animals possessing distinct differentiated cell types requires a mechanism to regulate the cellular decision to differentiate or remain undifferentiated. Notch is a […]
How many times might complex brains have evolved
Meeting Abstract 87.5 Monday, Jan. 6 11:15 How many times might complex brains have evolved? MOROZ, LL; Univ. of Florida moroz@whitney.ufl.edu The origin of complex centralized brains and elementary cognitive functions are two major evolutionary transitions in the history of our planet. We integrate a large-scale comparative neuronal transcriptome (>200 species) and genomic sequencing data (from several […]
