Summary: Pacific island land snails exhibit high species and morphological diversity, with the Belau archipelago in the Republic of Palau providing a unique opportunity to study this diversity. The study found evolutionary relationships and geographic ranges among endemic Pacific punctoid species, shedding light on their long evolutionary history and diversification through geographic isolation. Additionally, evidence for species-level shifts and reproductive isolation within specific punctoid species was also uncovered.

Summary: This paper discusses the accumulation and concentration ratio of Cs-137 and stable elements in different parts of the Giant African snail (Lissachatina fulica) after consuming contaminated forage and/or soil over a long period of time. The activity concentration of Cs-137 in their bodies initially increased but significantly reduced after 40 days. The distribution of Cs-137 in the snail's body follows the order of gastrointestinal tract > body = albumin gland > shell. The contamination of snails by Cs-137 is mainly derived from forage rather than soil, despite the higher biological availability of Pb and U in forage compared to soil.

Summary: This study reconstructs temperature and body water composition of terrestrial snails using carbonate clumped isotope values and oxygen isotope composition of their shells, providing insights into regional and sub-regional paleoclimates and paleoecosystems. The study finds different growth patterns in snail shells from different geographical regions, and the δ O-18 (body water) values in snail shells are enriched relative to the δ O-18 (precipitation) values.

Summary: In tropical countries, land snails are an important food source, but the risks of foodborne diseases have not been well quantified. We detected Campylobacter spp., Yersinia spp., Listeria spp., Salmonella spp., or Shiga-toxigenic Escherichia coli in 57%-86% of snails in Cameroon. Therefore, snail meat is likely to contribute to the transmission of enteric diseases in subSaharan African countries.

Summary: Fire has a direct and dramatic effect on soil fauna and non-mobile species like land snails. Understanding how community structure and function change after fire is important for biodiversity management. The study shows that both taxonomic and functional changes occur in land snail communities after a fire.

Summary: The Chile Nino/Nina has a significant impact on regional climate and marine ecosystem in the southeast Pacific. While the prediction system can capture its occurrences and related climate impacts, the predicted magnitudes are weaker than observed, attributing to the inadequacy in reproducing the coastal ocean-atmosphere-land positive feedback. Improving model resolution and ensemble size may enhance the prediction skills of these coastal climate modes.

Summary: The study found that habitat characteristics such as forest continuity, width, and abundance of dead wood significantly influenced the abundance and diversity of snail communities in central European riparian forests. Fragmentation was identified as the main factor affecting the abundance of land snail communities. The total abundance of land snail communities and species richness were good predictors of habitat quality, with snail abundance being more powerful than diversity in indicating riparian forest quality.

Summary: Stephadiscus lyratus, an endemic snail species from southern South America, was found to primarily inhabit cold native forest areas, mainly living on or under humid logs in contact with the ground. The potential distribution range of this species extends to the Valdivian Temperate forests mainly in Chile, but only a small portion of its range falls within protected areas in Argentina and Chile. This, combined with its physiological traits and habitat requirements, indicates that S. lyratus is a potentially vulnerable species.

Summary: This study investigated the genetic patterns of a freshwater microgastropod species, Heleobia atacamensis, in a system highly affected by anthropic activities. The results show that the populations are highly fragmented and mainly influenced by historical geographic isolation, with little impact from contemporary factors. Additionally, no signs of demographic instability were detected, despite high environmental heterogeneity.

Summary: Terrestrial snails living in warm and dry climates have developed strategies to survive high summer temperatures, with many species estivating on vertical supports during the warmest months. Understanding their preferences for estivation sites could lead to new management tools for invasive species. In this study, four invasive snail species were observed to strongly prefer wider supports in both laboratory and field conditions, with one species showing a preference for taller supports as well. The presence of conspecifics or snails of other species did not affect their choices, suggesting the possibility of developing attractive supports for mass-capturing snails in the field.

Summary: This paper reviews the hydrological processes in Chilean temperate forests, covering a range of natural and planted forests in diverse environmental settings. It highlights the importance of forested catchments for local communities, freshwater ecosystems, and downstream economic activities. The review identifies knowledge gaps and proposes future research directions to improve understanding of forest hydrology in Chile.

Summary: This study investigated the land snail diversity and abundance in a threatened limestone hill in Mfamosing, Nigeria. The results showed relatively high diversity and moderate abundance of land snails in this area. The carnivorous Streptaxidae family and the Urocyclidae family dominated in terms of species richness and abundance respectively. The study highlights the importance of urgent conservation measures for the biodiversity hotspot in Mfamosing limestone hill.

Summary: Based on the study, it is suggested that sampling for land snails should be conducted during the wet period to obtain a complete survey of malacofauna. Collection and inspection of soil and litter are also necessary for such a survey. Regular resurveys are crucial for assessing the temporal dynamics of biodiversity patterns.

Summary: The study analyzed the polycyclic aromatic hydrocarbon (PAH) content in Giant African snails collected from different zones in southern Nigeria. It found that some samples exceeded the permissible limits for PAH concentrations, posing potential carcinogenic risks to consumers. The PAHs in these snail samples were mainly sourced from oil spills, biomass combustion, traffic emissions, and gas flaring.

Summary: Land-use change, particularly the expansion of agriculture, leads to biodiversity loss. Ecological intensification, aiming to increase crop yields while conserving biodiversity and ecosystem services, is important. This study assessed vertebrate diversity in apple and cherry crops, finding that diversity and abundance of native species increased in crops surrounded by more natural vegetation. The presence of exotic species explained most differences. Therefore, maintaining natural areas nearby crop fields is crucial for enhancing biodiversity and the ecosystem services provided by native species.

Summary: This study combined citizen science with species distribution models to analyze the ecology and conservation status of the endemic leech Americobdella valdiviana in the Valdivian evergreen forest in southern Chile. The research found high levels of habitat loss and fragmentation in the north and central zones of the species range, leading to its classification as endangered under IUCN Red List criteria. The results highlight the importance of utilizing citizen science, SDM, and spatial analysis to inform conservation actions for poorly known and threatened species.
