Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

Environmental Toxicology, Volume 41, Issue 11, Page 1125-1138, November 2026.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Composición, abundancia y distribución de las poblaciones de gasterópodos de importancia comercial en La Guajira, Caribe colombiano Composition, abundance and distribution of populations of commercially important gastropods in La Guajira, Colombian Caribbean

Revista de Biología Tropical, 2013
En el Caribe continental colombiano el aprovechamiento del recurso caracol y el estado de sus poblaciones han sido poco estudiados, esto se refleja en la carencia de un ordenamiento pesquero.

Flashy Neighbours: Psilocladus mantilleri Zeballos, Nunes, Silveira & Rosa, sp. nov., the First Termitariophile Firefly Larva (Coleoptera: Lampyridae)

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Fireflies are semelparous beetles whose immature stages are largely unknown. The comparatively few larvae known span diverse ecological niches, such as ground‐dwellers, aquatic (freshwater or marine), semi‐aquatic and arboreal. Psilocladus costae Vaz, Silveira & Rosa, 2020—a bromeliad dweller—is the only species of its genus and subfamily in ...

Diet of schistosome vectors influences infection outcomes

Ecosphere
Resource availability can alter infection outcomes through its impact on host immunity and on parasite reproduction. On one hand, enhanced nutrition could favor immunity, limiting the parasite, and on the other hand, it could favor establishment and ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, Volume 249, Issue 5, Page 1021-1032, November 2026.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Snail coprophagy: the encounter filter, food preferences, and rat lungworm (Angiostrongylus cantonensis) prevalence

Parasite
Understanding the factors driving infection prevalence among host species is crucial for effective disease mitigation. Angiostrongylus cantonensis, the rat lungworm, causes neuroangiostrongyliasis and serves as an excellent model for studying infection ...

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, Volume 55, Issue 6, Page 830-845, November 2026.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Marchantia polymorpha Defense Against Snail Herbivory

Plant-Environment Interactions
During the course of evolution, higher plants have developed efficient strategies to cope with herbivory from arthropods. Upon perception of herbivore‐derived cues, the jasmonic acid (JA) signaling pathway is activated and triggers the expression of ...

Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.
