Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

open access: yesJournal of Quaternary Science, Volume 41, Issue 2, Page 333-360, February 2026.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Optimizing Computed Tomography (CT) for Structurally Complex Organisms: A Case Study of Gastropod Shell Features

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We developed and tested a computed tomography (CT) protocol to estimate shell volume as a method instead of using water and sand. We compared the estimates obtained using this protocol (OCT, optimized CT) with traditional methods (water and sand) and with a CT previous setting (NOCT, nonoptimized CT).

Refuge trifecta: intertidal gastropods use pits to escape heat, wave action and predation

open access: yesOikos, Volume 2025, Issue 10, October 2025.
Refuges play a critical role in ecology and evolution. In hard intertidal shores, small pits attract benthic invertebrates such as gastropods, however, there exists little mechanistic understanding of the processes driving the active usage of these microhabitat features. We conducted a series of laboratory experiments to assess whether the marine snail

Evolution of Duplicated Hox Gene Clusters in Land Snails and Slugs

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 6, Page 363-368, September 2025.
Molluscs of the order Stylommatophora underwent an ancient genome duplication. We show that stylommatophoran snails and slugs have two broken and incomplete Hox gene clusters; HoxA generally has 9 genes, HoxB usually has 7 genes. After duplication of an ancestral 11‐gene Hox cluster, there was patchwork retention of duplicated genes.

Imposex incidence in Stramonita haemastoma (Gastropoda: Muricidae) from the Mediterranean and Atlantic coast after Tributyltin global ban

open access: yesJournal of Sea Research, 2018
Abstract The development of male genital tract by female gastropods, or imposex, can be caused by the tributyltin used in antifouling paints. A spatial survey of imposex in the gastropod Stramonita haemastoma was conducted across five Western Mediterranean and eleven North-Eastern Atlantic sites, in order to monitor the effectiveness of the ...

Shell occupation by the endemic western Atlantic hermit crab Isocheles sawayai (Diogenidae) from Caraguatatuba, Brazil

open access: yesBrazilian Journal of Biology
The aim of this study was to characterize the pattern of shell occupation by the hermit crab Isocheles sawayai Forest and Saint-Laurent, 1968, from the Caraguatatuba region.

Habitat heterogeneity in the assemblages and shell use by the most abundant hermit crabs (Anomura: Diogenidae and Paguridae): does the occupied shell species differ according to gender and species?

open access: yesNauplius
The goal of this study was to identify patterns of shell occupation by different species of hermit crabs from the southern Brazilian coast. In total, 644 individuals were collected, represented by six hermit species.

Shell occupation by the hermit crab Dardanus insignis (Decapoda, Diogenidae) from the north Coast of São Paulo state, Brazil

open access: yesBrazilian Journal of Biology
The pattern of shell occupation by the hermit crab Dardanus insignis (Saussure, 1858) from the subtropical region of southeastern coast of Brazil was investigated in the present study. The percentage of shell types that were occupied and the morphometric

Unexpected mosaic distribution of two hybridizing sibling lineages in the teleplanically dispersing snailStramonita haemastomasuggests unusual postglacial redistribution or cryptic invasion

open access: yesEcology and Evolution, 2017
AbstractMolecular approaches have proven efficient to identify cryptic lineages within single taxonomic entities. Sometimes these cryptic lineages maybe previously unreported or unknown invasive taxa. The genetic structure of the marine gastropodStramonita haemastomahas been examined in the Western Mediterranean and North‐Eastern Atlantic populations ...
