“…A number of species, especially those most abundant in polluted harbors, can tolerate and accumulate as adults heavy metals such as arsenic, cadmium, chromium, cobalt, copper, iron, lead, mercury, selenium, tin (as tributyltin), and zinc (Papadopoulou and Kanias 1977;Philp et al 2003). All of these metals, but especially tributyltin, have dosedependent toxic effects on the development of embryos and larvae (Cima et al 1996;Bellas et al 2001;Beiras et al 2003) and on many enzyme functions including those involved in the immune response (Tujula et al 2001;Cima et al 2002;Azumi et al 2004;Cima and Ballarin 2004).…”

The last comprehensive reviews of ecology and natural history of ascidians were included in the excellent 1971 publication by Millar on the biology of ascidians and the 1991 treatise on New Caledonia ascidians by Monniot, Monniot, and Laboute. Several hundred papers have been published since that time, greatly expanding our knowledge of environmental tolerances and responses to increasing levels of anthropogenically derived toxins in marine waters, energetics and feeding strategies, predator-prey relationships, competition both intra-and inter-specific that include many studies of self-nonself recognition in colonial species, modes and environmental regulation of reproduction and development, symbionts, natural-product chemistry as antifouling and antipredator defenses, and dispersal mechanisms. The relatively new field of molecular genetics is revealing the presence of cryptic species and is helping to determine the origin of anthropogenically transported individuals, an important and growing problem that affects natural ecological relationships in marine communities worldwide. We are learning more about the difficult-to-study abyssal and Antarctic species. There have been great advances in our understanding of the importance in open-ocean food webs of the planktonic Appendicularia and Thaliacea. Also included in this review is a brief discussion of recent work on the Cephalochordata and Hemichordata.

“…In polluted areas, ascidians can take up and accumulate metals and toxic substances, acting as active filters for purification and cleaning of coastal waters and becoming important pollution bio‐indicators ( Papadopolou & Kanias 1977; Naranjo et al . 1996 ).…”

Isolation and characterization of microsatellite loci in the ascidian Ciona intestinalis (L.)

“…Ascidians are benthic animals that populate coastal marine habitats with strong natural fluctuations of physico‐chemical parameters and high levels of pollution (Caputi, Crocetta, Toscano, Sordino, & Cirino, ; Carver, Chisholm, & Mallet, ; Dybern, ; Lambert, ; Simkanin, Davidson, Dower, Jamieson, & Therriault, ). These invertebrates are non‐selective filter feeders that uptake and bioaccumulate metals and other pollutants from the environment (Ignatiades & Becacos‐Kontos, ; Papadopoulou & Kanias, ; Radford, Hutchinson, Burandt, & Raftos, ). Due to their tolerance to biotoxic metals (Beiras et al, ), ascidian species such as Ciona robusta ( Ciona intestinalis type A) are considered potential bioindicators of metals in marine and estuarine habitats (Bellas, Vázquez, & Beiras, ; Gallo & Tosti, ; Papadopoulou & Kanias, ).…”

Mechanisms of resistance to pollutants have not been well elucidated to date, but ascidians likely defend themselves against the effects of metal‐based pollutants by using different strategies such as detoxification, antioxidant systems, and reduced metabolism (Ueki, Uwagaki, Yamamoto, & Michibata, ).…”

Temporal correlation of population composition and environmental variables in the marine invader Ciona robusta

et al. 2019

The capacity for ascidians to inhabit coastal sea floor worldwide relies on their peculiar tolerance to environmental variables and pollution, which is considered, together with high levels of genetic diversity, among the main drivers of their invasive potential. In spite of the continued interest in the genetics of invasive species, little attention has been paid toward the microevolutionary processes that drive structure and fate of ascidian populations over time under chemically polluted conditions. Understanding the interplay between environmental and population dynamics is critical to predict the biodiversity of marine coastal ecosystems. In the present study, a local population of the ascidian Ciona robusta living in the Fusaro Lagoon has been monitored over a 13‐month period of sampling. Physico‐chemical parameters (temperature, salinity, turbidity, dissolved oxygen, heavy metals), genetic composition (microsatellites, ITS‐2), abundance and biomass (wet and dry weight) were assessed with the aim to infer fine‐scale temporal variation of population structure with respect to rapid environmental change. Analysis of biomass showed that C. robusta is highly sensitive to salinity and oxygen concentrations. Further, genetic analysis suggested a highly dynamic population structure, likely due to the strong clustering of temporal samples and distinct responses to environmental conditions, including bioaccumulation of heavy metals. Here, we hypothesize that rapid variation in allele frequencies of neutral markers in C. robusta populations may increase the ability of the species to colonize habitats that are subject to strong variation and are under heavy human pressure.
