DEGNAN, BM*; ADAMSKA, M; University of Queensland; University of Queensland: Pre-mesoderm: the expression of Wnts during sponge gastrulation and their ancestral role in metazoan development While the original body plan from which all living metazoans evolved remains obscure, recent insights into the genome and development of basal animals, such as cnidarians, ctenophores and sponges, suggest […]

Mesoderm development in arthropods a view from crustaceans
PRICE, Alivia L.*; PATEL, Nipam H.; The Salk Institute; Univ. of California, Berkeley; Howard Hughes Medical Institute: Mesoderm development in arthropods: a view from crustaceans The Arthropoda is a highly diverse group of organisms including the Chelicerata, Myriapoda, Crustacea, and Insecta. Studies of comparative development in arthropods can benefit from the vast amount of knowledge […]
An Endodermal Origin of Mesoderm
BURTON, Patrick M*; PANG, Kevin; KRONE, Cassandra; MARTINDALE, Mark; FINNERTY, John; University of Maryland; University of Hawaii; Boston University; University of Hawaii; Boston University: An Endodermal Origin of Mesoderm Mesoderm played a critical role in the radiation of triploblastic bilaterians, allowing the evolution of more complex body plans than their diploblastic predecessors. The diploblastic phylum […]
A Nanos ortholog is required for endomesoderm specification in the snail Ilyanassa
KINGSLEY, Evan P.; RABINOWITZ, Jeremy; LAMBERT, J. David*; University of Rochester; University of Rochester; University of Rochester: A Nanos ortholog is required for endomesoderm specification in the snail Ilyanassa In the several animal phyla with spiralian development, most of the mesodermal structures are thought to derive from one particular cell, the 4d micromere. This cell […]
Transgenerational Offspring Size Effects in Marine Invertebrates
MARSHALL, D.J.; University of Queensland: Transgenerational Offspring Size Effects in Marine Invertebrates In marine invertebrates, the larval and adult stages of many species are often ecologically distinct and as consequence these stages have been traditionally been viewed as physiologically separate. More recently, we have begun to recognize that metamorphosis does not represent a new beginning […]
Recruitment of marine organisms around Wellington, New Zealand a model natural system to examine causes and consequences of variability in larval quality in mussels and reef fish
PHILLIPS, N.E.*; SHIMA, J.S.; Victoria University of Wellington; Victoria University of Wellington: Recruitment of marine organisms around Wellington, New Zealand: a model natural system to examine causes and consequences of variability in larval quality in mussels and reef fish Accumulating evidence from laboratory experiments on a range of marine taxa indicates that variation in larval […]
REVISITING SYNCHRONOUS SPAWNING IN SEAWEEDS IS IT JUST ABOUT SEX
PEARSON, GARETH A*; SERRAO, ESTER A; Universidade do Algarve; Universidade do Algarve: REVISITING SYNCHRONOUS SPAWNING IN SEAWEEDS � IS IT JUST ABOUT SEX? External fertilization is common in the marine environment. However, in the intertidal zone the prevailing hydrodynamic conditions may reduce the effectiveness of external fertilization as a reproductive strategy by dilution of the […]
Multiple paternity and subsequent fusionrejection interactions in a colonial ascidian
YUND, P.O.*; JOHNSON, S.L.; CONNOLLY, L.E.; Univ. of New England; Univ. of Maine; Univ. of New England: Multiple paternity and subsequent fusion/rejection interactions in a colonial ascidian The production of genetically variable offspring is a central function of sexual reproduction. The genetic composition of offspring subsequently affects many processes that operate on adults. Although much […]
Influence of early life history traits on recruitment success and early survival in a coral reef fish
SPONAUGLE, S.*; GRORUD-COLVERT, K.; RSMAS, Univ. of Miami; RSMAS, Univ. of Miami: Influence of early life history traits on recruitment success and early survival in a coral reef fish For organisms with complex life histories, life history traits of early stages may influence the survival of subsequent stages. We surveyed and collected 13 monthly cohorts […]
Functional properties of algal life cycles
THORNBER, C.S.; Univ. of Rhode Island: Functional properties of algal life cycles Many species of algae have complex, multiphasic life cycles. These species contain multiple independent, free-living stages that they either obligately or selectively cycle between. The inherent complexities of these life cycles provide unique opportunities for investigating the ecological dynamics and tradeoffs between the […]
