Ruiz Legacy Program Abstract: SSpecies introductions have increased dramatically in number, rate, and magnitude of impact in recent decades. In marine systems, invertebrates are the largest and most diverse component of coastal invasions throughout the world. Ascidians are conspicuous and well-studied members of this group, however, much of what is known about their invasion history is limited to particular species or locations. Here, we provide a large-scale assessment of invasions, using an extensive literature review and standardized field surveys, to characterize the invasion dynamics of non-native ascidians in the continental United States and Alaska. -

Populations were found along the eastern Connecticut shoreline in October 2009. At one site C. lepadiformis had a mean percent cover of 19.95% (±4.16 S.E.). A regional survey suggests that the invasion is relatively localized. Genetic analysis confirms our morphological identification and places the introduced population in the previously described ‘Atlantic clade’. While it appears Clavelina lepadiformis is currently in the incipient stage of introduction in eastern Connecticut waters, its spread to other areas in the region could lead to competition with resident members of shallow water epifaunal assemblages and shellfish species. -

Awesome Ascidians a Guide to the Sea Squirts of New Zealand Version 2, 2016

AWESOME ASCIDIANS is a fully illustrated e-guide to the sea squirts of New Zealand. It is designed for New Zealanders like you who live near the sea, dive and snorkel, explore our coasts, make a living from it, and for those who educate and are charged with kaitiakitanga, conservation and management of our marine realm. It is one in a series of electronic guides on New Zealand marine invertebrates that NIWA’s Coasts and Oceans centre is presently developing. The e-guide starts with a simple introduction to living sea squirts, followed by a colour index, species index, detailed individual species pages, and finally, icon explanations and a glossary of terms. As new species are discovered and described, new species pages will be added and an updated version of this e-guide will be made available online. Each sea squirt species page illustrates and describes features that enable you to differentiate the species from each other. Species are illustrated with high quality images of the animals in life. As far as possible, we have used characters that can be seen by eye or magnifying glass, and language that is non technical. -

Abstract: Marine tunicates are identified as a potential source of marine natural products (MNPs), demonstrating a wide range of biological properties, like antimicrobial and anticancer activities. The symbiotic relationship between tunicates and specific microbial groups has revealed the acquisi- tion of microbial compounds by tunicates for defensive purpose. For instance, yellow pigmented compounds, “tambjamines”, produced by the tunicate, Sigillina signifera (Sluiter, 1909), primarily Citation: Ramesh, C.; Tulasi, B.R.; originated from their bacterial symbionts, which are involved in their chemical defense function, indi- Raju, M.; Thakur, N.; Dufossé, L. cating the ecological role of symbiotic microbial association with tunicates.

An Elongated COI Fragment to Discriminate Botryllid Species And
www.nature.com/scientificreports OPEN An elongated COI fragment to discriminate botryllid species and as an improved ascidian DNA barcode Marika Salonna1, Fabio Gasparini2, Dorothée Huchon3,4, Federica Montesanto5, Michal Haddas‑Sasson3,4, Merrick Ekins6,7,8, Marissa McNamara6,7,8, Francesco Mastrototaro5,9 & Carmela Gissi1,9,10* Botryllids are colonial ascidians widely studied for their potential invasiveness and as model organisms, however the morphological description and discrimination of these species is very problematic, leading to frequent specimen misidentifcations. To facilitate species discrimination and detection of cryptic/new species, we developed new barcoding primers for the amplifcation of a COI fragment of about 860 bp (860‑COI), which is an extension of the common Folmer’s barcode region. Our 860‑COI was successfully amplifed in 177 worldwide‑sampled botryllid colonies. Combined with morphological analyses, 860‑COI allowed not only discriminating known species, but also identifying undescribed and cryptic species, resurrecting old species currently in synonymy, and proposing the assignment of clade D of the model organism Botryllus schlosseri to Botryllus renierii. Importantly, within clade A of B. schlosseri, 860‑COI recognized at least two candidate species against only one recognized by the Folmer’s fragment, underlining the need of further genetic investigations on this clade. This result also suggests that the 860‑COI could have a greater ability to diagnose cryptic/ new species than the Folmer’s fragment at very short evolutionary distances, such as those observed within clade A. Finally, our new primers simplify the amplifcation of 860‑COI even in non‑botryllid ascidians, suggesting their wider usefulness in ascidians. -

The Ebro Delta is one of the major centres of bivalve production in the 30 20 Mediterranean and is affected by proliferation of ascidian species (mostly introduced 31 21 forms). Knowledge of the patterns of settlement and growth of the fouling species is 32 22 mandatory to attempt mitigation measures. We deployed settlement PVC plates from May 33 34 23 to September 2015 at different depths (0.2, 1 and 2 m) in the Ebro Delta oyster 35 24 aquaculture facilities. We then monitored the occurrences of all species and the area cover 36 25 of a selected subset of 6 species on a monthly basis from June 2015 to December 2016. -
Earliest Japanese Record of the Invasive European Ascidian Clavelina Lepadiformis Complex (Urochordata: Ascidiacea)
