First Frozen Repository for Coral Sperm in the Southwestern Atlantic: A Tool to Support Reef Conservation

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Coral reefs are among the most biodiverse ecosystems on Earth, yet they are rapidly declining due to climate change and other anthropogenic stressors. Population reductions threaten sexual reproduction in sessile coral species, as increased distances between colonies hinder gamete encounters.

Occurrence of ascidian Molgula sp. from the coastal waters of Visakhapatnam, India [PDF]

open access: yes, 2011
Ascidians referred to as ‘sea squirts’ constitute a major component of biofouling community in coastal waters. Knowledge of diversity of ascidians in the waters around India is very less.

De novo draft assembly of the Botrylloides leachii genome provides further insight into tunicate evolution [PDF]

open access: yes, 2018
Tunicates are marine invertebrates that compose the closest phylogenetic group to the vertebrates. These chordates present a particularly diverse range of regenerative abilities and life-history strategies.

Multi‐Omics‐Driven Adaptive Management of Biological Invasions: Toward a Proactive, Predictive, and Integrative Framework

open access: yesBiological Diversity, Volume 2, Issue 4, Page 163-192, December 2025.
A proactive, predictive, and integrative framework that integrates multi‐omics innovations with ecological modeling and big data analytics to guide adaptive interventions and governance in invasive species management. By integrating multi‐omics insights with advanced ecological modeling, remote sensing, artificial intelligence, and cross‐disciplinary ...

Phylogenetic Relationships between Solitary and Colonial Ascidians, as Inferred from the Sequence of the Central Region of their Respective 18S rDNAs.

open access: yesThe Biological Bulletin, 1992
Ascidians (tunicates) are primitive chordates. In spite of their elevated phylogenetic position in the animal kingdom, ascidians have evolved a varied reproductive repertoire; some of them live as individuals (solitary ascidians), while others form ...

The colonial ascidian Diplosoma listerianum enhances the occurrence of the hydrozoan Obelia sp. during early phases of succession [PDF]

open access: yes, 2018
Recruitment patterns of sessile species often do not reflect the composition of the local propagule pool. This is, among other processes, attributed to the stimulation or inhibition of settlement by resident species.

Long‐term warming and record‐breaking marine heatwaves in the Hauraki Gulf, northern New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1678-1689, December 2025.
ABSTRACT As global oceans warm, long‐term temperature records are critical in understanding and interpreting warming trends and the significance of marine heatwaves (MHWs) in coastal environments. Daily measurements of sea surface temperature (SST) have been taken since 1967 at the Leigh Marine Laboratory, Hauraki Gulf, northern New Zealand. We analyse

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 ...

Changing bryozoan fauna in Otago Harbour reflects growing urbanisation and globalisation

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 957-978, December 2025.
ABSTRACT A comparison between historic reports dating from 1884 (78 records of 35 species) to the bryozoan fauna present today (98 colonies of 14 species) reveals considerable faunal change in Otago Harbour / Te Wai Ōtākou (45° 50'S 170° 38'E) in Dunedin, east coast of South Island, Aotearoa New Zealand.

Temporal stability of bacterial symbionts in a temperate ascidian [PDF]

open access: yes, 2015
In temperate seas, both bacterioplankton communities and invertebrate lifecycles follow a seasonal pattern. To investigate whether the bacterial community associated with the Mediterranean ascidian Didemnum fulgens exhibited similar variations, we ...
