Amyloid and allorecognition in the colonial ascidian Botryllus schlosseri. [PDF]

open access: yes, 2017
Allorecognition, i.e., the ability of intraspecific nonself recognition is widely distributed among colonial, sessile marine organisms in the form of colony specificity. In the cosmopolitan compound ascidian Botryllus schlosseri, colony specificity is controlled by a highly polymorphic Fu/HC locus: two colonies sharing at least one alleleat the Fu/HC ...

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

open access: yesRestoration Ecology, Volume 34, Issue 5, July 2026.
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.

Ecology of intertidal and sublittoral cryptic epifaunal assemblages. II. Nonlethal overgrowth of encrusting bryozoans by colonial ascidians

open access: yes, 1988
Total overgrowth of encrusting cheilostome bryozoans by sheet-like colonial ascidians is commonly observed in epifaunal sessile assemblages on marine hard substrata.

The impacts of biological invasions

open access: yesBiological 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

Colony specificity in Botrylloides leachi. I. Morphological aspects [PDF]

open access: yesInvertebrate Survival Journal, 2006
We studied colony specificity in the colonial ascidian Botrylloides leachi which, as in other botryllid ascidians, leads to either fusion or non-fusion between contacting colonies.

Reef fish assemblages impacted by sponges overgrowing corals

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Numerous stressors are driving long‐term declines in coral cover on coral reefs, significantly impacting reef fish biodiversity and community structure. The benthic space made available by declining coral cover is often occupied by increases in other organisms, including macroalgae, encrusting ascidians, and sponges.

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

open access: yesReviews 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 ...

Comparing competitive interactions and settlement success among native and non-indigenous species in marine hard bottom communities of colonial ascidians, from the Bay of Plenty, New Zealand [PDF]

open access: yes, 2020
The requirement for space in marine hard bottom assemblages is paramount for life. Due to the crowded nature and demand for space in these sessile assemblages, bare space that is freed is quickly occupied. The intense push and pull for space within these

Common and divergent pathways in alternative developmental processes of ascidians [PDF]

open access: yes, 2006
Colonial ascidians offer opportunities to investigate how developmental events are integrated to generate the animal form, since they can develop similar individuals (oozooids from eggs, blastozooids from pluripotent somatic cells) through very ...

The Microbiome of the Worldwide Invasive Ascidian Didemnum vexillum

open access: yesFrontiers in Marine Science, 2020
All multicellular organisms, including ascidians, host diverse microbial communities that are essential for their evolution. The global invader Didemnum vexillum is a colonial species native to Japan with two main genetic clades, A (the only invasive ...
