The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

open access: yesInsect Molecular Biology, EarlyView.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Morphological and metabarcoding dietary analysis of the cunner wrasse (Tautogolabrus adspersus) revealed significant regional variation, with large overlap between its common prey species and biofouling animals living on salmonid sea cages

open access: yesJournal of Fish Biology, EarlyView.
Abstract The stomach‐less cunner wrasse (Tautogolabrus adspersus) has been experimentally used as a biological control agent for salmon lice that infest Atlantic salmon (Salmo salar) and to remove biofouling inside sea cages. The cunner demonstrates a strong population structure, suggesting that its diet, and therefore its usefulness for biological ...

Multiple hybridization events and repeated evolution of homoeologue expression bias in parthenogenetic, polyploid New Zealand stick insects

open access: yesMolecular Ecology, EarlyView.
Abstract During hybrid speciation, homoeologues combine in a single genome. Homoeologue expression bias (HEB) occurs when one homoeologue has higher gene expression than another. HEB has been well characterized in plants but rarely investigated in animals, especially invertebrates.

Wildfire‐Driven Changes in Terrestrial Subsidies Shift Freshwater Microbial and Zooplankton Communities to New Compositional States

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Wildfire frequency and intensity are increasing globally, impacting terrestrial and aquatic ecosystems. Deposition of burned materials into aquatic environments can affect biotic communities and nutrient cycling. We investigated how post‐fire terrestrial deposition shapes microbial and zooplankton community composition and function across time
