  • Improved phylogenetic resolution within Siphonophora (Cnidaria) with implications for trait evolution 
    Munro, Catriona; Siebert, Stefan; Zapata, Felipe; Howison, Mark; Damian Serrano, Alejandro; Church, Samuel H.; Goetz, Freya E.; Pugh, Philip R.; Haddock, Steven H. D.; Dunn, Casey W. (2018)
    Siphonophores are a diverse group of hydrozoans (Cnidaria) that are found at most depths of the ocean - from the surface, like the familiar Portuguese man of war, to the deep sea. They play important roles in ocean ecosystems, ...
  • Phylogenomic Analyses Support Traditional Relationships within Cnidaria 
    Zapata, Felipe; Goetz, Freya E.; Smith, Stephen A.; Howison, Mark; Siebert, Stefan; Church, Samuel H.; Sanders, Steven M.; Ames, Cheryl Lewis; McFadden, Catherine S.; France, Scott C.; Daly, Marymegan; Collins, Allen Gilbert; Haddock, Steven H. D.; Dunn, Casey W.; Cartwright, Paulyn (2015)
    Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic ...
  • Repeated loss of variation in insect ovary morphology highlights the role of development in life-history evolution 
    Church, Samuel H.; de Medeiros, Bruno A. S.; Donoughe, Seth; Reyes, Nicole L. Marquez; Extavour, Cassandra G. (2021)
    The number of offspring an organism can produce is a key component of its evolutionary fitness and life history. Here we perform a test of the hypothesized trade-off between the number and size of offspring using thousands ...
  • Stem cells in Nanomia bijuga (Siphonophora), a colonial animal with localized growth zones 
    Siebert, Stefan; Goetz, Freya E.; Church, Samuel H.; Bhattacharyya, Pathikrit; Zapata, Felipe; Haddock, Steven H. D.; Dunn, Casey W. (2015)
    BACKGROUND: Siphonophores (Hydrozoa) have unparalleled colony-level complexity, precision of colony organization, and functional specialization between zooids (i.e., the units that make up colonies). Previous work has shown ...
