The earliest cowries: the origin of cypraeoid gastropods

open access: yesActa Palaeontologica Polonica
Cowries, the family Cypraeidae, form a diverse and conspicuous group of gastropods living in tropical to subtropical seas. Their shell is convolute (last whorl covers all previous ones) with a narrow, slit-like siphonate aperture bearing denticles ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Developing a Fecal DNA Method With Blocking Primers to Determine Red Knots' (Calidris canutus) Diets Noninvasively

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
The blocking primer suppressed Red Knot DNA while improving detection of other prey taxa. We detected horseshoe crab in the Fall fecal samples, suggesting their use goes beyond the spring migration period of the Red Knots. ABSTRACT Understanding the diets of migratory shorebirds such as the Red Knot (Calidris canutus) is essential for evaluating ...

DNA Extraction Optimisation for Minute Land Snails of Vertigo Müller, 1773 (Gastropoda: Vertiginidae): A Comparative Evaluation of Six Methods, Including a Non‐Destructive Shell‐Preserving Protocol

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We compared six DNA extraction methods for minute Vertigo land snails, including a rapid non‐destructive HotSHOT protocol that preserves shells. The shell‐preserving protocol produced sequenceable DNA from very small and conservation‐relevant specimens while retaining voucher morphology.

A problematic zygopleuroid gastropod Acanthostrophia revisited [PDF]

open access: yes, 2010
SEM examination of the type series of Acathostrophia acanthica CONTI & FISCHER, 1984 from Middle Jurassic of Italy has shown that this gastropod most likely belongs to the family Protorculidae as previously suggested by NÜTZEL (1998). It is also similar

Diet and Prey Selection of Migratory Shorebirds on Virginia Mudflats Revealed by Fecal DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
Fecal DNA metabarcoding revealed species‐specific diets of migratory shorebirds on Virginia mudflats, highlighting mudflats as diverse foraging habitats and uncovering a previously undocumented biofilm pathway in mid‐Atlantic shorebird food webs.

Soil Contamination Around the Copper Smelter and the Use of Soil Microarthropods as Bioindicators

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 11384-11403, September 2026.
ABSTRACT Soil contamination from smelter emissions, including heavy metals (HM), rare earth elements (REEs), and sulfur, poses a significant threat to soil ecosystems. In the immediate vicinity of the Głogów Copper Smelter, HM concentrations were several times higher than in more distant forest stands.
