The egg-cowries comprise a family of specialised carnivorous caenogastropods (Ovulidae Fleming, 1828) that feed by browsing on octocorals, hexacorals and stylasterid hydrozoans. A recent phylogenetic study, employing a Sanger-based multilocus nucleotide dataset, revealed numerous instances of morphological-molecular incongruence and raised the need for a revision of the current classification. To test alternative hypotheses of ovulid classifications, we applied a phylogenomic approach relying on an Exon-capture methodology to 41 samples from 26 genera and 41 species, representative of the subfamily- and genus-level diversity. Tree reconstructions were performed using both Maximum Likelihood and Bayesian inference methods, resulting in a total of five well-supported subfamily-level clades. The genera Jenneria and Pseudocypraea formed a monophyletic clade, sister to Pedicularia, altogether here considered as forming the subfamily Pediculariinae. The monophyly of Ovulinae was upheld, incorporating Quasisimnia. Prionovolvinae as traditionally recognised proved to be a melting pot of diverse genera and species, including Ovula isibasii, challenging conventional morphology-based classifications. To further investigate morphological variation within Ovulidae, we conducted 2D geometric morphometric analyses to assess shape differences. Groups emerging from Principal Component Analysis (PCA) aligned with the traditional, morphology-based classification. The weak phylogenetic signal associated with the morphometric patterns suggested that phylogeny had only a marginal influence on the morphological evolution of this clade, in contrast to the much stronger role played by host adaptation. This phylogenetic reassessment based on robust genomic data, not only helped to refine our taxonomic framework but also underscores the power of molecular insights in investigating complex evolutionary relationships within families such as the Ovulidae. Furthermore, the morphometric multivariate analysis proved efficient in revealing patterns and addressing eco-evolutionary links.

Propolis from Apis mellifera and cerumen from Tetragonula carbonaria are complex mixtures of beeswax, plant resins, and bee secretions whose composition varies with geography and species. Understanding these differences is important for exploring their bioactive potential. This study employs untargeted quantitative 1H NMR metabolomics to characterize A. mellifera propolis from Scandinavia (Denmark and Norway) and Australia, as well as cerumen from T. carbonaria in Australia. Hydrophilic and hydrophobic extracts were analyzed to assess compositional differences across geographical origin and bee species, and to link specific metabolites to radical scavenging activity (RSA). Principal component analysis (PCA) of the 1H NMR spectra showed a marked separation between Scandinavian and Australian propolis. Hydrophilic extracts showed that Scandinavian propolis contains higher levels of aromatic compounds, whereas Australian propolis is richer in carbohydrates. In contrast, cerumen from T. carbonaria exhibits higher amounts of terpenoids. Hydrophobic extracts revealed that Australian propolis has the highest wax content, with shorter chains and more free fatty acids, while Scandinavian propolis samples display uniform wax structures and the highest aromatic content. Multivariate regression using recursive weighted partial least squares (rPLS) to RSA prediction highlighted signals attributable to ferulic acid and p-coumaric acid, which were confirmed by statistical total correlation spectroscopy (STOCSY). These findings demonstrate the utility of quantitative 1H NMR metabolomics for distinguishing botanical and geographic chemotypes of propolis and cerumen. The findings further show that Scandinavian propolis is more consistent with respect to metabolite composition compared to Australian samples, presumably reflecting differences in resin sources for foraging.
