Barcoding of the cytochrome oxidase I (COI) indicates a recent introduction of Ciona savignyi into New Zealand and provides a rapid method for Ciona species discrimination [PDF]
, 2012 Mitochondrial cytochrome oxidase I (COI) gene sequencing (DNA barcoding) of Ciona specimens from New Zealand (NZ) led to the first record of the solitary ascidian Ciona savignyi in the Southern Hemisphere. We sought to quantify C.

Continued persistence of non-native ascidians in Southern California harbors and marinas [PDF]
Aquatic Invasions, 2023 Non-native ascidians have long dominated the artificial structures in southern California’s (United States) marinas and harbors. To determine the change in ascidian abundance and community composition over the last several decades, in 2019–2020 we ...

Effects of temporal variability of disturbance on the succession in marine fouling communities in northern-central Chile [PDF]
, 2007 We investigated the effects of temporal variability in a disturbance regime on fouling communities at two study sites in a northern-central Chilean bay. Fouling assemblages grown on artificial settlement substrata were disturbed by mechanical removal of ...

Phagocytosis in the colonial ascidian Botryllus schlosseri
Developmental & Comparative Immunology, 1994 Phagocytosis by Botryllus schlosseri hemocytes is influenced by temperature, pH, concentration, and physicochemical properties of the test particles and requires Ca2+ or Mg2+ ions to occur. Phagocytes recognize glucosyl or mannosyl residues on the surface of yeast cells, and a respiratory burst is associated with phagocytosis, as indicated by increased

Transcriptome dynamics in the asexual cycle of the chordate Botryllus schlosseri [PDF]
, 2016 Background: We performed an analysis of the transcriptome during the blastogenesis of the chordate Botryllus schlosseri, focusing in particular on genes involved in cell death by apoptosis. The tunicate B.

Ascidiacea (Chordata, Tunicata) de Uruguay (Atlántico SO): Checklist y consideraciones zoogeográficas [PDF]
, 2018 The diversity of ascidians from the Southwestern Atlantic between 30°S and 40°S (southern Brazil, Uruguay and northern Argentina) remains as one of the poorest known of the West Atlantic.
