The inaudible impact: physiological stress responses to ultrasonic exposure in the solitary ascidian Ciona intestinalis

Frontiers in Marine Science
Ultrasonic technologies are increasingly deployed in coastal and marine environments for antifouling, sonar, underwater communication, and ballast water treatment; however, their biological effects on sessile invertebrates remain poorly understood.

Immunotoxicity in ascidians: the case of organotin compounds

, 2000
Although simple filter-feeding organisms, due to their high sensitivity to pollutants, ascidians can provide useful information on the molecular mechanism of action of specific xenobiotics.

Toxic grip of copper(I) and booster dichlofluanid in coastal ecosystems: unraveling the impact of antifouling paints on sea urchin development

Frontiers in Marine Science
Copper-based antifouling paints supplemented with organic booster biocides are a major source of chemical contamination in coastal marine ecosystems. However, the combined effects of copper(I) and emerging booster biocides on non-target marine organisms ...

Possible Evolutionary Precursors of Mast Cells: The ‘Granular Cell’ Immunocyte of Botrylloides leachii (Tunicata; Ascidiacea)

Journal of Marine Science and Engineering
Vertebrate mast cells are the first cells to initiate the inflammatory response. The origin of these highly specialised innate immunity cells in chordates is an intriguing unanswered question, and tunicates represent the best candidates to address this ...

Iceland: a laboratory for non-indigenous ascidians [PDF]

, 2020
Non-indigenous species (NIS) represent a serious problem worldwide, where ascidians are one of the most important taxa. However, little has been done to document the non-indigenous ascidians in Iceland, and over the past decade only two species had been ...

Ascidians Collected in Tanzania

Journal of East African Natural History, 1997
Ascidians were collected in Tanzania in January 1996 by SCUBA diving. Among 31 species reported here, nine are new. Several species were also recently collected in Mozambique. Full descriptions are given with figures and colour plates. The present collection of Tanzanian ascidians significantly increases the number of species known in the tropical ...

Secondary contacts and genetic admixture shape colonization by an amphiatlantic epibenthic invertebrate

Evolutionary Applications, 2020
Research on the genetics of invasive species often focuses on patterns of genetic diversity and population structure within the introduced range. However, a growing body of literature is demonstrating the need to study how native genotypes affect both ...

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
