The molecular mechanisms of defensive‐grade organic acid biosynthesis in ground beetles
Insect Molecular Biology, EarlyView.Formic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.

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

Journal of Biogeography, EarlyView.ABSTRACT Aim The relationships between environmental variables and macroinvertebrate assemblages depend on spatial extent, but the relative importance of local and regional factors remains unclear. Understanding these scale‐dependent relationships is crucial for improving biodiversity assessments and ecosystem management.
