Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

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

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
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

Biofouling reduction by lantern nets exchange and its relationship with production and survival of Argopecten purpuratus in Samanco Bay, Peru

Journal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract The aquaculture of Argopecten purpuratus (Peruvian scallop) is a profitable activity with positive impacts on the local economy. However, the development of biofouling on the culture lantern nets generates negative environmental impacts that affect its sustainability.

Biostratigraphy and correlation of the Cambrian Series 2 (Stage 4) to Miaolingian (Wuliuan) Thorntonia Limestone, south‐eastern Georgina Basin (Queensland, Australia)

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The Australian Cambrian stratigraphic record is one of the most complete for any continent. However, there is a general division, with older Cambrian rocks in South Australia (predominantly Terreneuvian, Stage 2 to Miaolingian, Wuliuan) and younger rocks in northern Australia (mostly latest Series 2, Stage 4 and younger), with minimal ...

Between the Poles: Rethinking Global Patterns in Sea Anemone Biodiversity

Journal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim To assess global sampling coverage of sea anemones and global species richness across four different spatial resolutions, and analyse these along latitudinal gradients to investigate true bimodality and the extent to which these patterns have been influenced by uneven sampling efforts. Location The study encompasses a global scale.

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 4, Page 198-213, June 2025.
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.
