Patterns of Autonomous and Conditional Neural Specification for the Brain and Ventral Nerve Cord in Annelida

Evolution &Development, Volume 28, Issue 3, September 2026.
Diagrams of blastomere isolations in Capitella teleta and Platynereis dumerilii showing autonomous head neural tissue (from 1q) and trunk neural tissue (from 2d) as well as a decoupling of D–V axis formation from trunk neural tissue in annelids. ABSTRACT Evolution of central nervous systems is a long‐debated topic.

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

Journal 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 ...

“Keep on rolling”: circulating cells in a botryllid ascidian torpor

Frontiers in Ecology and Evolution, 2023
Hemocytes of the colonial tunicate Botrylloides leachii play important roles throughout the animal’s life span, including transport and storage of nutrients, respiration, regeneration, budding, sexual reproduction, defense responses, and tunic generation.

Consumer diversity drives stronger predation in tropical marine communities

Ecography, Volume 2026, Issue 8, August 2026.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Cellular and molecular mechanisms of regeneration in colonial and solitary Ascidians

Developmental Biology, 2019
Regenerative ability is highly variable among the metazoans. While many invertebrate organisms are capable of complete regeneration of entire bodies and organs, whole-organ regeneration is limited to very few species in the vertebrate lineages. Tunicates, which are invertebrate chordates and the closest extant relatives of the vertebrates, show robust ...

Beta Diversity and Rarity Assessment of Sessile Cryptobenthic Communities Across Depth and Islands Can Inform Coral Reef Conservation

Diversity and Distributions, Volume 32, Issue 8, August 2026.
ABSTRACT Aim This study investigates a poorly known component of coral reefs, the cryptobiome, species that live hidden within the reef matrix, essential for reef functioning and productivity. It focuses on patterns of diversity and rarity of sessile cryptobenthic communities across Mascarene islands, and across shallow and mesophotic habitats (in deep

Antagonistic effect of bacteria associated with ascidians from Thoothukudi coast [PDF]

, 2016
1208-1217The antagonistic properties of marine ascidians and the bacteria associated with them were investigated. Ascidians were collected from submerged structures along the coast of Thoothukudi and four species of solitary ascidians and four colonial ...

Immunotoxicity in ascidians: the case of organotin compounds

, 2000
Although simple filter-feeding organisms, due to their high sensitivity to pollutants, ascidians can provide useful information on the molecular mechanism of action of specific xenobiotics.

Feasibility of restoring native oyster reefs in highly modified urban estuaries

Restoration Ecology, Volume 34, Issue 5, July 2026.
Abstract Introduction Urbanized estuaries are highly altered systems characterized by modified shorelines, degraded marine habitats, and abundant non‐native species. In South Australia's largest urbanized estuary, community‐based restoration initiatives aim to restore native flat oyster reefs (Ostrea angasi) lost over a century ago.
