Effects of color variation and physiological state on ascidian microbiomes

open access: yesMicrobiologyOpen
Ascidians, known for their color variation, host species‐specific microbial symbiont communities. Some ascidians can also transition into a nonfiltering (resting) physiological state.

Pyrosome fecal pellet production: Implications for grazing and carbon export

open access: yesLimnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract This study quantifies the fecal pellet production and pellet sinking rates of the pyrosome Pyrosoma atlanticum in the Southern California Current across a range of conditions, from the productive nearshore to the oligotrophic offshore. Fecal pellet production rates averaged 1310 ± 76 pellets h−1, resulting in the production of up to 390,380 ...

Giant phytoplankton revealed by in situ imaging

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Calcium Binding Dramatically Stabilizes an Ancestral Crystallin Fold in Tunicate βγ-Crystallin [PDF]

open access: yes, 2016
The tunicate (Ciona intestinalis) βγ-crystallin represents an intermediate case between the calcium-binding proteins ancestral to the vertebrate βγ-crystallin fold and the vertebrate structural crystallins.

A simple inland culture system provides insights into ascidian post-embryonic developmental physiology

open access: yesOpen Biology
Maintenance and breeding of experimental organisms are fundamental to life sciences, but both initial and running costs, and hands-on zootechnical demands can be challenging for many laboratories. Here, we first aimed to further develop a simple protocol

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Transforming Life Science Through Chromosome‐Level Genome Assemblies

open access: yesGenes to Cells, Volume 31, Issue 5, September 2026.
Chromosome‐level genome assemblies provide a framework for “glocal biology” in species of interest, linking local molecular features to chromosome architecture and evolutionary context. When integrated with pangenome analysis, comparative multi‐omics, genome language models, and experimental approaches, these assemblies enable hypothesis generation and

The Uncultured Gamma Proteobacterium and Culturable Associated-Bacteria from Tunicate Herdmania momus [PDF]

open access: yes
Tunicate associated bacteria have been widely known as secondary metabolite producers. Beside the culturable bacteria, little is known about uncultured tunicate associated bacteria.

New Clavelina (Ascidiacea) Species from the Bahamas

open access: yesTaxonomy
The ascidian fauna of the Bahamas remains grossly understudied. Here, we examined specimens of the genus Clavelina collected from four Bahamian islands using morphological observations and genetic barcoding.

Circumglobal Distribution of the Benthic Ctenophore Vallicula multiformis (Rankin 1956), Documented Through Diverse Observation Types

open access: yesJournal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim To improve our understanding of the distribution of Vallicula multiformis, we integrate a series of diverse observation types, including citizen science records, published literature, metagenomic datasets, published sequences, and newly acquired material, to evaluate whether geographically isolated records reflect a single broadly ...
