Information-theoretic signatures of biodiversity in the barcoding gene

open access: yes, 2018
The COI mitochondrial gene is present in all animal phyla and in a few others, and is the leading candidate for species identification through DNA barcoding.

The early expansion and evolutionary dynamics of POU class genes. [PDF]

open access: yes, 2014
The POU genes represent a diverse class of animal-specific transcription factors that play important roles in neurogenesis, pluripotency, and cell-type specification. Although previous attempts have been made to reconstruct the evolution of the POU class,

Characterization of dermatan sulfate and chondroitin sulfate profiles during brain regeneration in Styela plicata

open access: yesThe FEBS Journal, EarlyView.
Adult ascidians are capable of regenerating their entire brains following injury, and glycosaminoglycans have been shown to either promote or inhibit neuritogenesis. In this study, dermatan 2,6‐disulfate (D2,6S) was identified as the predominant complex carbohydrate in the ascidian brain.

Exploring depth‐related patterns of sponge diversity and abundance in marginal reefs

open access: yesEcology and Evolution
Marine sponges play a vital role in the reef's benthic community; however, understanding how their diversity and abundance vary with depth is a major challenge, especially on marginal reefs in areas deeper than 30 m.

Neosuberitenone, a New Sesterterpenoid Carbon Skeleton; New Suberitenones; and Bioactivity against Respiratory Syncytial Virus, from the Antarctic Sponge Suberites sp.

open access: yesMarine Drugs, 2023
Respiratory syncytial virus (RSV) is a highly contagious human pathogen that poses a significant threat to children under the age of two, and there is a current need for new small molecule treatments. The Antarctic sponge Suberites sp.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

New Sesterterpenes from the Antarctic Sponge Suberites sp.

open access: yesMarine Drugs
Chemical investigation of the Antarctic sponge Suberites sp. has previously led to the identification of new suberitane derivatives, some of which show bioactivity toward respiratory syncytial virus (RSV).

Pilliga Ghosts: The Novel Fungi of the Rivers, Creeks, Lakes, and Dams of the Narrabri Region, Australia

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Freshwater systems of the semi‐arid Narrabri region, Australia, are hotspots of novel fungal and eukaryote diversity, dominated by zoosporic fungi and unclassified lineages. ITS‑based DNA and water chemistry analyses across various water bodies revealed strong seasonal patterns, a scarcity of aquatic hyphomycetes that may reflect environmental ...
