Description of a New Species of Eusynstyela (Ascidiacea: Stolidobranchia) from Okinawa, Japan with Molecular Insight into Its Phylogenetic Position

open access: yesSpecies Diversity
The colonial styelid genus Eusynstyela Michaelsen, 1904 comprises 12 species. Seven colonies of Eusynstyela were collected via SCUBA diving from three coastal sites in Okinawa, Japan, between 2018 and 2023.

Crustaceans as Key Prey: Insights Into the Dietary Partitioning of Four Carnivorous Fishes in the Nansha Islands, South China Sea

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
This study, through a combination of morphological analysis, molecular identification, and stable isotope analysis, confirmed that crustaceans are the primary food source for these fishes. Small carnivorous fishes reduce niche overlap by selectively feeding on different types of crustaceans—a strategy supported by the abundant crustacean resources in ...

Heat limits scale with metabolism in ectothermic animals

open access: yesJournal of Animal Ecology, Volume 94, Issue 6, Page 1307-1316, June 2025.
We show that the extent to which ectotherms can increase their heat limits is strongly linked to how metabolic rate scales with temperature. This is a new perspective on what sets temperature limits in organisms, and will be important for understanding and predicting how different animals will respond to future warming.

A Biosynthetic and Taxonomic Atlas of the Global Lichen Holobiont

open access: yesEnvironmental Microbiology, Volume 27, Issue 6, June 2025.
This analysis of 794 publicly available lichen shotgun metagenomic datasets, covering 467 unique lichen species from 34 countries, revealed that lichens are complex holobionts. They harbour a variety of fungal, algal, and bacterial players with remarkable biosynthetic capabilities.
