Distribuição da classe Thaliacea (Tunicata) em frente a costa do estado do Rio de Janeiro
Plankton was sampled at 63 station's during “Operação Rio de Janeiro I” in horizontal, vertical and oblique plankton hauls. The class Thaliacea was studied through the ohservation of 17.928 organims divided in 6 species: Salpa fusiformis, Thalia democratica, T. cicar, Doliolum nationalis Doliolum …

Resource Partitioning in Seven Species of Sympatric Intertidal Chitons (Mollusca: Polyplacophora)
… ciliata, ~· lignosa, M. muscosa, and Katharina tunicata; and Ischnochitonidae - Tonicella lineata and Cyanoplax dentiens. Species distribution relative to intertidal height (-0.3m to +0.9m) showed significant differences. M. hindsii, ~· ciliata, M. lignosa, and T. lineata preferred slopes or …

Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates
Trade-offs between filtration rate and swimming performance among several salp species with distinct morphologies and swimming styles were compared. Small-scale particle encounter at the salp filtering apparatus was also explored. Observations and experiments were conducted at the Liquid Jungle …

Taxonomic studies on adult and larval ascidians from California
The primary purpose of this research is to further morphological studies on larval ascidians and to encourage greater reliance on larval structures in ascidian taxonomy. This may necessitate some revisions in current classifications, but it is hoped that such revisions will lead to a better …

Combining microbial functional metagenomics and Caenorhabditis elegans genetics to uncover and characterise novel bioactive compounds
Marine bacteria produce a wide array of biologically active metabolites involved in defence strategies and pathogenesis against a range of metazoans target organisms. In return bacteriovorous metazoans, including nematodes, have developed sophisticated strategies to neutralise or avoid such …
