Spectral decomposition unlocks ascidian morphogenesis. [PDF]

Elife
Describing morphogenesis generally consists in aggregating the multiple high-resolution spatiotemporal processes involved into reproducible low-dimensional morphological processes consistent across individuals of the same species or group.

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.

Colonial Ascidian Populations at Inshore Coral Reefs of Norfolk Island, South Pacific

Diversity
Subtropical coral reefs such as the lagoonal reefs of Norfolk Island in the remote South Pacific are vastly understudied, with many benthic species unrecorded in the scientific literature.

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

Advanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Caelestines A-D, brominated quinolinecarboxylic acids from the Australian ascidian Aplidium caelestis [PDF]

, 2010
Four new brominated natural products, caelestines A-D (1-4), have been isolated from the Australian ascidian Aplidium caelestis. The structures of 1-4 were determined by analysis of their NMR and MS data.

Spatial Variability in a Symbiont-Diverse Marine Host and the Use of Observational Data to Assess Ecological Interactions

Diversity, 2022
Despite a rich taxonomic literature on the symbionts of ascidians, the nature of these symbioses remains poorly understood. In the Egyptian Red Sea, the solitary ascidian Phallusia nigra hosted a symbiotic amphipod and four copepod species, with ...

Review of the fauna associated with wild and farmed mussels and oysters in the Mediterranean

Biological Reviews, EarlyView.
ABSTRACT Mussels and oysters are important ecosystem engineers which modify the physical and chemical characteristics of the environment and create habitats that support highly diverse associated communities. In the Mediterranean Sea, the native Mediterranean mussel Mytilus galloprovincialis and the European flat oyster Ostrea edulis, together the ...

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Patterns, drivers and implications of ascidian distributions in a rapidly deglaciating fjord, King George Island, West Antarctic Peninsula

Ecological Indicators, 2021
We report strong evidence for the utility of ascidian communities as sentinel organisms for monitoring nearshore Antarctic marine ecosystem response to climate-induced warming and glacial melting. Ascidians are one of the most common Antarctic epibenthic
