Vanadium accumulation in ascidians: A system overview [PDF]

, 2015
Several families of ascidians accumulate extremely high levels of vanadium in their blood cells. The concentration of vanadium has been determined in each species; the highest concentration, found in Ascidia gemmata, reaches 350mM, corresponding to 107 ...

The Mediterranean Sea on the Bench: Unveiling the Marine Invertebrate Sidnyum elegans as a Source of Novel Promising Therapeutic Tools Against Triple-Negative Breast Cancer

Marine Drugs
This study aims to unveil the marine invertebrate Sidnyum elegans, a Mediterranean ascidian, as a natural resource for the early development of new treatments for triple-negative breast cancer (TNBC). Nine different fractions obtained via medium-pressure

Kelp‐boulder transplants for habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Degraded habitats present a major barrier to the survival and recovery of threatened marine species, particularly where structural or biogenic complexity has been lost, and natural regeneration ability is uncertain. Despite growing interest in habitat restoration, techniques rarely deliver rapid improvements at the necessary ...

Taxonomic and Metabolite Diversity of Actinomycetes Associated with Three Australian Ascidians

Diversity, 2017
Actinomycetes are known to be the most prolific producers of biologically active metabolites. Here, we investigated the host species-specificity and the related secondary metabolites of actinomycetes that are associated with three different Australian ...

From environmental heterogeneity to stability: Beta‐diversity stabilizes biomass across space

Ecology, Volume 107, Issue 9, September 2026.
Abstract Understanding how biodiversity influences ecosystem stability across heterogeneous landscapes is a central challenge in ecology. The spatial insurance hypothesis proposes that turnover in species composition stabilizes ecosystem processes in heterogeneous environments if species dominate in the habitats to which they are best adapted.

The chemistry of Algoa Bay ascidians [PDF]

, 2016
This thesis investigates the chemistry of 25 ascidian species collected from Algoa Bay, South Africa with a concerted focus on metal accumulation by these ascidians and the possible interaction of these metals with ascidian metabolites. Chapter 2 details

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, Volume 95, Issue 9, Page 1762-1777, September 2026.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

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.

Functional Properties of Ascidians By-products: Nutritional and Medicinal Value

, 2013
The generation of ascidians by-products has been a crucial problem to solve in regards to environmental or resource utilization. Researchers have investigated various methods of utilization, and those efforts provide great opportunities to develop high ...

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 ...
