The study of prey-predator interactions between land snails and birds offers important insights into evolutionary and ecological relationships. Here, we report a case study of rock anvils presumably used by the birds and in a cave cavity of a limestone hill in Malaysia. We did not detect any other species in the plots and, therefore, based on our short study duration, we cannot rule out the possibility that other species, such as mammals, preyed on the snails. The predated shell remains of four land snails namely, sp., , and , were found around rock anvils in the nine plots. Finally, we discussed the potential and the limitations of using shell remains of preyed land snails for behavioural, ecological and evolutionary studies between land snails and their predators.

Unlabelled: , the greater Bermuda land snail, is a critically endangered species and one of only two extant members in its genus. These snails are one of Bermuda's few endemic animal clades and their rich fossil record was the basis for the punctuated equilibria model of speciation. Once thought extinct, recent conservation efforts have focused on the recovery of the species, yet no genomic information or other molecular sequences have been available to inform these initiatives.

The remarkable phenotypic plasticity of land snail shells often results in convergent evolution, leading to frequent taxonomic misidentifications and non-monophyletic classifications. The taxonomy of the Holarctic micro land snails related to Euconulus fulvus has been particularly challenging to resolve. This study integrates mitochondrial and nuclear DNA phylogenetics, geometric morphometrics, and climate suitability modeling to clarify the phylogenetic and taxonomic status of an East Asian lineage within this group.

Greece is home to numerous endemic land snail species, sometimes with highly restricted distributions. Several species of , representing all three subgenera, live there. Although the genus was taxonomically revised in 2014, there remained some open questions and the distribution ranges of individual species are still incompletely known.

Recent studies have shown the significant role of introgression in evolution, yet the confident evidence of introgression has come from biased taxa. Although the Mollusca were representative taxa to show introgression-driven evolution, conclusive examination has been rare. Here, we investigated the genetic structure and evolutionary history of terrestrial snails in the Euhadra peliomphala species complex (Heterobranchia: Camaenidae).

We present the first synthesis of all known terrestrial endemic species extinctions in the biogeographical region of Macaronesia, covering all archipelagos (Azores, Madeira, Selvagens, the Canaries, and Cabo Verde) and multiple taxa (arthropods, birds, bryophytes, fungi, land molluscs, lichens, mammals, reptiles, and vascular plants). This list also includes information on the original distribution of extinct species, extinction chronologies, and likely causes of extinction, as reported by the original works' authors. Our survey identified 220 extinction records, with the highest numbers observed among land snails (111 species), arthropods (55), birds (27), and reptiles (15).
