Protein Science, Volume 35, Issue 5, May 2026.Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Forecasting the Risk of Reinvasion by the Giant African Snail in Ogasawara, Japan
Biotropica, Volume 58, Issue 3, May 2026.This study used SDMs constructed in multiple regions to predict the suitable habitats of Achatina fulica on Chichijima in the Ogasawara Islands. The model constructed on another island with a wide distribution range showed the highest predictive accuracy.

Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]
, 2013 In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Drivers of Microbiome Composition Among Helminth Parasites Sharing the Same Insectivorous Bat Host
Molecular Ecology, Volume 35, Issue 10, May 2026.ABSTRACT Parasitic metazoans are increasingly recognised to form close associations with microbial taxa. Under the holobiont concept, these associations are an eco‐evolutionary unit under joint selection. However, for most parasitic helminth species and particularly those associated with wildlife, these interactions and their effect on parasite ...

Evolutionary history of the Tricladida and the Platyhelminthes: an up-to-date phylogenetic and systematic account [PDF]
, 2012 Within the free-living platyhelminths, the triclads, or planarians, are the best-known group, largely as a result of long-standing and intensive research on regeneration, pattern formation and Hox gene expression.

Molecular Ecology, Volume 35, Issue 10, May 2026.ABSTRACT Faster evolution of mitochondrial genomes relative to nuclear genomes creates selective pressure on nuclear genes involved in mitochondrial function to preserve mitonuclear compatibility required for energy production. In isolated populations, such coevolution occurs independently.

Beyond BLASTing : ribonucleoprotein evolution via structural prediction and ancestral sequence reconstruction [PDF]
, 2016 Primary homology in DNA and protein sequence has long been used to infer a relationship between similar sequences. However gene sequence, and thus protein sequence, can change over time.
