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

open access: yesGlobal 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

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

open access: yesFisheries 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

Middle-out reasoning for synthesis and induction [PDF]

open access: yes, 1995
We develop two applications of middle-out reasoning in inductive proofs: Logic program synthesis and the selection of induction schemes. Middle-out reasoning as part of proof planning was first suggested by Bundy et al [Bundy et al 90a].

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

open access: yesInternational 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

open access: yesLimnology 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

open access: yesAustral 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.
