A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

open access: yesBoreas, Volume 55, Issue 2, Page 585-599, April 2026.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Shelf‐Life Study of Refrigerated, Vacuum‐Packaged, Ready‐to‐Eat Hot‐Smoked, South African Choromytilus meridionalis

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
The South African Choromytilus meridionalis is a marine aquaculture bivalve species underutilised for human consumption as a ready‐to‐eat (RTE) product. Hot smoking is a widely used method for preparing RTE seafood products. This study investigated the physicochemical (pH, water activity, and colour), lipid oxidation, and microbiological ...

Bioaccumulation of Heavy Metals in Finfish and Shellfish Samples From Tano River, Ghana: A Food Safety Issue

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
This study investigates mercury (Hg), cadmium (Cd), and arsenic (As) contamination in water, sediments, finfish, and shellfish from the Tano River in Ghana’s Western North Region. Forty‐eight fish and shellfish samples (12 species) and 27 paired water/sediment samples were analyzed.

A Morphological Characterization of High Yield Chitin from Periwinkle Shells

open access: yesJournal of Casting & Materials Engineering, 2020
Research on obtaining chitin from periwinkle shell is scarce due to the very low yield of chitin from this kind of shell. Thisstudy reports a method of processing periwinkle shells to obtain high yield, bio-medically suitable chitin. The experimentwas designed using IM and 2M concentrations of HCl for demineralization and a 1M NaOH concentration for ...

Development of Eco-Friendly Transformer Oil from Neem Seed Oil using Periwinkle Waste Shell as Catalyst

open access: yesEnvironmental and Climate Technologies, 2022
The urge for a sustainable and non-polluting industry has raised the need for a search for an alternative insulating fluid that could be used in transformers, because of the negative environmental effect of mineral-based insulating fluids. Natural esters

Latitudinal variation in the constitutive and inducible defences of a canopy‐forming rocky intertidal seaweed

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3718-3731, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A long‐standing theory in biogeography is that stronger biotic interactions at lower latitudes select for better‐defended phenotypes. However, greater environmental variability at temperate latitudes may also shape defensive strategies by increasing temporal or local ...

A fully automated heart frequency logger for shelled invertebrates and associated data processing R package

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 12, Page 2797-2806, December 2025.
Abstract Measuring cardiac frequency provides a non‐invasive approach to quantifying sublethal stress responses of invertebrates to environmental stressors, such as heat stress. Existing cardiac monitoring methods rely on limited‐performance hardware, and data processing is still largely manual or semi‐automated.
