Structural similarities reveal an expansive conotoxin family with a two‐finger toxin fold

open access: yesProtein Science, Volume 34, Issue 11, November 2025.
Abstract Venomous animals have evolved a diverse repertoire of toxins with considerable pharmaceutical potential. The rapid evolution of peptide toxins, such as the conotoxins produced by venomous marine cone snails, often complicates efforts to infer their evolutionary relationships based solely on sequence information.

Urban Ponds and the Emerging Role of Garden Ponds: Ecosystem Services and Disservices, Multifunctionality, and Trade‐Offs

open access: yesWIREs Water, Volume 12, Issue 6, November/December 2025.
Urban ponds and garden ponds—a specific subset of the former, usually located in private gardens—are both typical examples of ponds in the urban landscape. They deliver multiple ecosystem services but can also contribute to ecosystem disservices. The role of garden ponds is largely unknown compared to other urban ponds.

Comparative Genomics of Sex‐Determination‐Related Genes Reveals Shared Evolutionary Patterns Between Bivalves and Mammals, but Not Fruit Flies

open access: yesMolecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT The molecular basis of sex determination (SD), while being extensively studied in model organisms, remains poorly understood in many animal groups. Bivalves, a diverse class of molluscs with a variety of reproductive modes, represent an ideal yet challenging clade for investigating SD and the evolution of sexual systems.
