Functional diversity of zooplankton declined sharply with increasing eutrophication in hypereutrophic fishponds, despite stable species richness. Community assembly shifted from competition to habitat filtering, leading to functional homogenization (redundancy) and altered interactions among functional guilds. Ponds with total phosphorus below 300 μg/L

The morphology and cellulosic composition of the tunic was studied in pelagic tunicates (3 pyrosomas, 2 doliolids, and 13 salps). The tunic is transparent and gelatinous, consisting of an electron-dense cuticular layer with a fibrous tunic matrix. The thickness and density of the cuticular layer and of the tunic matrix differ from species to species ...

The Biodiversity of Peter I Island—The Most Remote Island in the World
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

ABSTRACT Understanding diet composition is essential for unravelling trophic interactions in aquatic ecosystems. DNA metabarcoding, utilising various variable regions of the 18S rRNA gene, is increasingly employed to investigate zooplankton diet composition.

Molecular Evolution and Gene Diversity of Dermatan Sulfate Sulfotransferases in Ascidians
ABSTRACT Ascidians (Chordata, Tunicata) are model organisms for studying molecules, particularly sulfated glycosaminoglycans (GAGs), due to their phylogenetic proximity to vertebrates and unique GAG variants. Over‐sulfated dermatan sulfate (DS) contributes to proteoglycan diversity and cellular processes in metazoans.

Binary specification of nerve cord and notochord cell fates in ascidian embryos [PDF]
In the ascidian embryo, the nerve cord and notochord of the tail of tadpole larvae originate from the precursor blastomeres for both tissues in the 32-cell-stage embryo. Each fate is separated into two daughter blastomeres at the next cleavage.

Biomass‐to‐volume ratio as a central continuous functional trait for marine zooplankton
Abstract Gelatinous zooplankton are an important component of many ecosystems and important for ecosystem structure and carbon cycling. However, this group is generally not considered in biogeochemical models. Here we investigate the biomass‐to‐volume ratio as an underappreciated “master trait” that allows for the incorporation of a large diversity of ...
