Pyrosome fecal pellet production: Implications for grazing and carbon export
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 ...

Distribution of pelagic tunicates in the western part of the Bay of Bengal [PDF]
A total of thirty-three species and two varieties of pelagic tunicates are reported from the western part of the Bay of Bengal. The influence of the prevailing water movements, temperature and salinity on the distribution of pelagic tunicates at the ...

Giant phytoplankton revealed by in situ imaging
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

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

Data from: Tunicates and not cephalochordates are the closest living relatives of vertebrates
Tunicates or urochordates (appendicularians, salps and sea squirts), cephalochordates (lancelets) and vertebrates (including lamprey and hagfish) constitute the three extant groups of chordate animals.

Transforming Life Science Through Chromosome‐Level Genome Assemblies
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

Phallusiasterol C, A New Disulfated Steroid from the Mediterranean Tunicate Phallusia fumigata
A new sulfated sterol, phallusiasterol C (1), has been isolated from the Mediterranean ascidian Phallusia fumigata and its structure has been determined on the basis of extensive spectroscopic (mainly 2D NMR) analysis. The possible role in regulating the

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 ...
