Dark diversity of flea (Siphonaptera) assemblages in South American rodents: Latitudinal and altitudinal gradients

open access: yesEcological Entomology, Volume 51, Issue 5, Page 983-992, October 2026.
The dark diversity of compound flea communities increased from north to south. The dark diversity of compound flea communities increased from lower to higher altitudes. The dark diversity of component flea communities also increased from north to south but did not vary with altitude.

Paracamallanus cyathopharynx (Baylis, 1923) Infection in Clarias gariepinus (Burchell, 1822): Linking the Morphology of Wound‐Inflicting Structures to Histopathology

open access: yesJournal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT Paracamallanus cyathopharynx (Baylis, 1923) specimens were collected from the rectum of the African sharptooth catfish, Clarias gariepinus in Lake Heritage, Crocodile River in the Limpopo River system and in the Vaal River below the Vaal Dam. Attached and unattached parasites were studied with light and scanning electron microscopy along with ...

De Novo Assembly and Comparative Analysis of the Complete Mitochondrial Genome of Mesenchytraeus (Annelida, Enchytraeidae)

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This present the first mitochondrial genome dataset for 13 Mesenchytraeus species from the Changbai Mountain glacial refugium. Beyond characterizing standard genomic features, we perform comparative analyses of gene order, nucleotide composition, codon usage, and control region structure.

Complementary but Not Interchangeable: A Comparison of eDNA and Bulk Sample Metabarcoding for the Assessment of Groundwater Invertebrate Communities

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
Bulk‐ and eDNA‐metabarcoding were compared across 50 groundwater sites (monitoring wells, springs, hydrants) to assess invertebrate communities. Both recovered different community structures with limited overlap (13.8% OTUs); eDNA was dominated by non‐stygobionts, and bulk samples by stygobionts.

Selective Packaging of miR‐22 and miR‐29 Orthologues into Extracellular Vesicles of the Porcine Whipworm Trichuris Suis

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.
ABSTRACT Helminths modulate host immunity, and in this respect, the porcine whipworm Trichuris suis has been explored clinically as an immunotherapy for inflammatory diseases. T. suis secretes a complex mixture of excretory/secretory products (ESP), including extracellular vesicles (EVs), nanosized membranous particles with bioactive cargoes of lipids,
