Evidence for a Role of Hox2 in Atrial Siphon Fusion of the Ascidian Ciona

Development, Growth &Differentiation, Volume 68, Issue 8, October 2026.
ABSTRACT The hallmark of sessile adult ascidians is a vase‐like shape with a single oral and atrial siphon. Ciona, however, develops two atrial siphons after metamorphosis, which subsequently fuse into one. The mechanisms underlying this fusion are unknown. This study suggests that Hox2 controls this process.

Giant phytoplankton revealed by in situ imaging

Limnology 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

Selective Feeding and Microalgal Consumption Rates by Crown-Of-Thorns Seastar (Acanthaster cf. solaris) Larvae

Diversity, 2017
Outbreaks of the crown-of-thorns seastar (CoTS) represent a major cause of coral loss on the Great Barrier Reef. Outbreaks can be explained by enhanced larval survival supported by higher phytoplankton availability after flood events, yet little is known

Spatial Variability in Phytoplankton Response to Projected Increases in Iron and Temperature in the Ross Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Ross Sea supports massive phytoplankton blooms and exhibits the highest marine primary productivity rates due to seasonal relief of iron and light limitations. Although Earth System Models project regional increases in temperature and iron supply, there is uncertainty regarding the response of different phytoplankton communities. To assess

Interactive effects of flame retardant triphenyl phosphate and disposable face mask fibers in marine diatom Chaetoceros sp., and their effects on dietary exposure to marine crustacean Artemia salina

Environmental Sciences Europe
Plastic microfibers released from disposable face masks and triphenyl phosphate (ThP) are emerging contaminants of concern in the marine environment. However, there is a lack of scrutiny on their combined effect and dietary uptake in marine ecosystems ...

Exploration of Overlooked Aduncodinium‐Like (Pfiesteriaceae, Dinophyceae) Diversity

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT The dinoflagellate genus Aduncodinium was erected to encompass Katodinium glandula, belonging to the family Pfiesteriaceae. Other described species, like K. asymmetricum, show Aduncodinium‐like characters and probably belong to this genus. These two species are commonly reported in the literature.
