Tolerance to air exposure of the New Zealand mudsnail Potamopyrgus antipodarum (Hydrobiidae, Mollusca) as a prerequisite to survival in overland translocations [PDF]

open access: yes, 2013
Spreading throughout a new ecosystem is the last step of an exotic species to become invasive. In the case of invasive aquatic molluscs, tolerance to air exposure is one of the main mechanisms allowing overland translocation and spreading.

The double histone fold: Structure, functional implications across the tree of life and relevance to protein design

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The histone fold is one of the most ancient and versatile structural motifs in protein biology, best known for its role in chromatin organization. A remarkable variation of this motif is the double histone fold (DHF), in which two histone folds are encoded within a single polypeptide chain and assemble intramolecularly into a histone‐like ...

Novi prilozi poznavanju alohtone faune mekušaca uzduž ciparske obale: novi stražnjoškržnjaši u ciparskoj fauni [PDF]

open access: yes, 2011
The finding of some alien opisthobranchia previously unknown from Cyprus confirms that Indo-Pacific alien species are spreading at an increasing rate in the Levantine Sea. This work reports on the occurrence of four new alien species recorded in the form

Latitudinal Gradients of Species Richness in Marine Benthos: Insights From Japan's Tidal Flat Areas

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Latitudinal diversity gradients in species richness were observed in the coasts of Japan. Extensive tidal flats and biogeographical connectivity to the Eurasian Continent may cause the unexpected peak in species diversity at the Kyushu region. Mollusca was the dominant taxonomic group, followed by Malacostraca, Annelida, and other benthic groups ...

Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]

open access: yes, 2006
Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

Stunting of the penis in Heleobia parchappii (Mollusca: Cochliopidae) and its relationship with parasitism [PDF]

open access: yes, 2017
Penis anatomy is used to discriminate species of gastropods belonging to the family Cochliopidae; however, this characteristic may be affected by the presence of parasites.

Conspecific Scaffold‐Level Genome Assembly Outperforms Heterospecific Chromosome‐Level Assemblies for Assessing Genetic Indicators in a Threatened Marine Fish

open access: yesEvolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Understanding the genomic architecture of species of conservation concern is essential for fostering effective conservation initiatives. Current biodiversity assessment approaches increasingly incorporate genetic metrics to evaluate the status of species and populations of conservation interest.

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]

open access: yes, 1987
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

AlkaPlorer: A database‐driven explorer for natural alkaloids and derivatives

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1384-1398, May 2026.
The alkaloid database AlkaPlorer integrates over 130,000 compounds across 12,250 species. By linking chemical structures with biological and evolutionary data, it reveals how these molecules evolve and function. This platform serves as a vital resource for AI‐driven discovery in plant metabolism and modern drug development. ABSTRACT Alkaloids, renowned
