Symbiotic copepods from the ascidians, a hidden diversity of the Mediterranean Sea: Haplostomides magnus n. sp. (Cyclopoida: Botryllophilidae)

The European Zoological Journal
This paper reports the first occurrence of five species of symbiotic copepods associated with ascidian species collected in two Sicilian harbours (southern Italy) in the central Mediterranean Sea.

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.

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, EarlyView.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.

Propagation method and species drive survival patterns across reef zones in coral seeding on the Great Barrier Reef

Restoration Ecology, EarlyView.
Abstract Introduction Coral reef restoration increasingly relies on scalable methods, yet outcomes vary across species, propagation techniques, and habitats. Coral seeding, where coral propagules are settled on deployment units before outplanting, provides a flexible approach that accommodates both asexual (e.g. microfragments) and sexual (e.g.

Structure and anticoagulant properties of sulfated glycosaminoglycans from primitive Chordates

Anais da Academia Brasileira de Ciências, 2002
Dermatan sulfates and heparin, similar to the mammalian glycosaminoglycans, but with differences in the degree and position of sulfation were previously isolated from the body of the ascidian Styela plicata and Ascidia nigra.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Metabolite profiling of ascidian Styela plicata using LC–MS with multivariate statistical analysis and their antitumor activity

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
To identify the metabolite distribution in ascidian, we have applied an integrated liquid chromatography– tandem mass spectrometry (LC–MS) metabolomics approach to explore and identify patterns in chemical diversity of invasive ascidian Styela plicata. A

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...
