Intraspecific Variation in Thermal Performance Suggests the Presence of Range‐Edge Divergence and Phenotypic Compensation of Northern Individuals in an Introduced Species

Global Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim Intraspecific variation in functional traits may indicate adaptation to environmental gradients and is crucial to understanding species distributions and range dynamics. We tested the hypotheses that: (1) thermal performance of Littorina littorea follows a countergradient cline, reflecting compensation in northern individuals and (2) local

A Morphological Characterization of High Yield Chitin from Periwinkle Shells

Journal 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 ...

Long‐Term Mobility of a Harvested, Rocky‐Reef Gastropod

Fisheries Management and Ecology, Volume 32, Issue 5, Page 189-202, October 2025.
ABSTRACT Stocks of Turbo militaris (Turbinidae) are under increasing harvesting pressure, but management is currently hampered by data deficiency. Management decisions for rocky‐reef gastropod fisheries should consider long‐term species mobility, yet this is often poorly understood. Therefore, mark‐recapture was used to evaluate annual displacement and

Investigating the influence of periwinkle shell powder on the thermal and mechanical performance of high-density polyethylene composites

Materials Research Express
In this study, the shell powder of Littorina littorea commonly called periwinkle was used as an eco-friendly filler in High-Density Polyethylene (HDPE) to form periwinkle/HDPE composites (PHPC).

Synthesis and Characterization of Nanocrystalline Hydroxyapatite (HAp) Utilizing Marine Mollusk Waste

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
ABSTRACT This experiment utilized oceanic mollusks, including Oliva sayana, Babylonia japonica, and Conasprella bermudensis, to synthesize hydroxyapatite (HAp). Orthophosphoric acid was reacted with the powdered components of marine mollusks, resulting in spherical and nanorod HAp.

Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

Limnology and Oceanography Letters, Volume 10, Issue 5, Page 680-691, September 2025.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Sea Country Change: Projected Poleward Range Shifts for Bioculturally Important Marine Gastropods Under Climate Change

Austral Ecology, Volume 50, Issue 9, September 2025.
ABSTRACT Turban snails (known as Gugumbal in Gumbainggir Country) are bioculturally important Sea Country molluscs distributed throughout south‐eastern Australia. Like most shallow water marine species, climate change is anticipated to result in poleward range shifts, or possibly even regional extinctions.

Combining co‐introduction with patch‐size optimization as a novel strategy to maximize seagrass restoration

Ecological Applications, Volume 35, Issue 4, June 2025.
Abstract Coastal ecosystem engineers, such as mussels, oysters, salt marsh grasses, and seagrasses, typically shape their environment by ameliorating stressors when they grow beyond a critical population size. In doing so, they not only facilitate themselves but also provide habitat for diverse communities, which in turn, can engage in reciprocal ...
