Broad phylogenomic sampling improves resolution of the animal tree of life
This data reinforce several previously identified clades that split deeply in the animal tree, unambiguously resolve multiple long-standing issues for which there was strong conflicting support in earlier studies with less data, and provide molecular support for the monophyly of molluscs, a group long recognized by morphologists.

The Genome of the Ctenophore Mnemiopsis leidyi and Its Implications for Cell Type Evolution
The genome of the ctenophore the warty comb jelly or sea walnut, Mnemiopsis leidyi, is sequenced and it is concluded that c tenophores alone, not sponges or the clade consisting of both ctenphores and cnidarians, are the most basal extant animals. Expand
Bioluminescence in the sea.
A review of recent advances in understanding of the molecular basis of bioluminescence, its physiological control, and its significance in marine communities explores recent advances, including the chemical and molecular, phylogenetic and functional, community and oceanographic aspects. Expand
A molecular phylogenetic framework for the phylum Ctenophora using 18S rRNA genes.
The first molecular phylogenetic analysis of the phylum Ctenophora, by use of 18S ribosomal RNA sequences from most of the major taxa, suggests that the ctenophores form a distinct monophyletic group that is most closely related to the cnidarians. Expand
Best Practices for Scientific Computing
We describe a set of best practices for scientific software development, based on research and experience, that will improve scientists' productivity and the reliability of their software.
Questioning the Rise of Gelatinous Zooplankton in the World's Oceans
It is concluded that the current paradigm in which it is believed that there has been a global increase in gelatinous Zooplankton is unsubstantiated, and a strategy for addressing the critical questions about long-term, human-related changes in the sea as they relate to gelatinousZooplanka blooms is developed.

Recurrent jellyfish blooms are a consequence of global oscillations
All available long-term datasets on changes in jellyfish abundance across multiple coastal stations are analyzed, using linear and logistic mixed models and effect-size analysis to show that there is no robust evidence for a global increase in Jellyfish abundance. Expand
Molecular phylogenetics of the siphonophora (Cnidaria), with implications for the evolution of functional specialization.
Maximum likelihood and Bayesian analyses of morphological data suggest that the transition rate for decreased functional specialization is greater than the Transition rate for increased functional specialization for three out of the four investigated categories of polyps and medusae. Expand
Evolutionary relationships among scyphozoan jellyfish families based on complete taxon sampling and phylogenetic analyses of 18S and 28S ribosomal DNA.
The molecular phylogeny presented here will facilitate more robust study of phenotypic evolution in the Scyphozoa, including the evolution characters associated with mass occurrences of jellyfish. Expand
