Modifications of Prenyl Side Chains in Natural Product Biosynthesis

open access: yesAngewandte Chemie, Volume 136, Issue 52, December 20, 2024.
This review summarizes the unique modifications of prenyl side chains involved in natural product biosynthesis, including epoxidation, dehydrogenation, oxidation of methyl groups to carboxyl groups, C−C bond cleavage and oxidative cyclization. Abstract In recent years, there has been a growing interest in understanding the enzymatic machinery ...

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

open access: yesJournal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Postglacial Echoes: Parasite Genomics Uncover Environmental Changes in Postglacial European Lakes

open access: yesMolecular Ecology, Volume 34, Issue 17, September 2025.
ABSTRACT Postglacial environmental changes have influenced biodiversity and species evolution, yet the genomic and demographic responses of parasites remain underexplored. This study investigates the population genetics and demographic history of the flatworm Phyllodistomum umblae, a generalist trematode at the definitive host level infecting Coregonus
