The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

open access: yesOikos, Volume 2026, Issue 4, April 2026.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

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.

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.
