Roles of oxygen and tidal cycle for embryonic incubation and hatching
Meeting Abstract S8.3 Thursday, Jan. 6 Roles of oxygen and tidal cycle for embryonic incubation and hatching ISHIMATSU, Atsushi*; GRAHAM, Jeffrey B; Nagasaki Univ., Nagasaki, Japan; Univ. of California, San Diego a-ishima@nagasaki-u.ac.jp Reproduction on mudflats requires that eggs are protected from different environmental challenges during development and hatch when environmental conditions are favorable for juvenile survival. Mudskippers […]
Predator and conspecific induced hatching in a marine snail
Meeting Abstract S8.8 Thursday, Jan. 6 Predator and conspecific induced hatching in a marine snail MINER, BG*; DONOVAN, DA; MORGAN, C; Western Washington University; Western Washington University; Western Washington University benjamin.miner@wwu.edu Inducible defenses are well studied in adult marine invertebrates. Some of the pioneering studies by Harvell, Lively, and Palmer on inducible defenses demonstrated that adult marine […]
Plasticity in Stage at Hatching that Controls Pelagic Duration and Dispersal in Marine Invertebrate Larvae
Meeting Abstract S8.9 Thursday, Jan. 6 Plasticity in Stage at Hatching that Controls Pelagic Duration and Dispersal in Marine Invertebrate Larvae OYARZUN, F. X.*; STRATHMANN, R. R.; University of Washington rrstrath@u.washington.edu Plasticity in hatching potentially adjusts risks of benthic and planktonic development for diverse benthic marine invertebrates. The proportionate effect on duration of larval swimming would be […]
Introduction to the Symposium – Eggs as organisms environmentally cued hatching and adaptive embryo responses to risk and opportunity
Meeting Abstract S8.1 Thursday, Jan. 6 Introduction to the Symposium – Eggs as organisms: environmentally cued hatching and adaptive embryo responses to risk and opportunity WARKENTIN, K.M.; Boston University, MA kwarken@bu.edu Most animals begin life as eggs, protected and constrained by a capsule, shell, or other barrier. As embryos develop, their needs and abilities change, and at […]
Hatching strategies in parasitic monogeneans (platyhelminths) that facilitate host infection
Meeting Abstract S8.10 Thursday, Jan. 6 Hatching strategies in parasitic monogeneans (platyhelminths) that facilitate host infection WHITTINGTON, I.D.*; KEARN, G.C.; South Australian Museum/University of Adelaide, Australia; University of East Anglia, Norwich, UK ian.whittington@samuseum.sa.gov.au In parasites, environmental cues have great potential to influence egg hatching and enhance infection success. Monogeneans are parasitic platyhelminths that are among the most […]
Hatching plasticity in amphibians evolution, trade-offs, cues and mechanisms
Meeting Abstract S8.5 Thursday, Jan. 6 Hatching plasticity in amphibians: evolution, trade-offs, cues and mechanisms WARKENTIN, K.M.; Boston University, MA kwarken@bu.edu At least 28 amphibian species from 7 families of frogs and salamanders alter hatching timing in response to conditions affecting egg or larval mortality. Some terrestrially laid or stranded embryos wait to hatch until they are […]
Evidence for Environmentally-cued Hatching in Reptiles
Meeting Abstract S8.4 Thursday, Jan. 6 Evidence for Environmentally-cued Hatching in Reptiles DOODY, J. Sean; Monash University, Melbourne, Australia sean.doody@monash.edu Reptilian embryos typically suffer high mortality from both biotic and abiotic sources (e.g., predation, pathogens, flooding, desiccation). When these threats are imminent embryos can escape the danger by accelerating or delaying hatching. Herein I review published and […]
