Pleistocene malacofauna of the Požarevac Danube area (NE Serbia) [PDF]
The results of recent analyses of loess samples from the localities: Ćirikovac, Klenovnik, Novi Kostolac, Zatonje and Kisiljevo, confirm the idea that malacological associations identify biotope characteristics.

A Phylogenomic Backbone for Gastropod Molluscs
AbstractGastropods have survived several mass extinctions during their evolutionary history resulting in extraordinary diversity in morphology, ecology, and developmental modes, which complicate the reconstruction of a robust phylogeny. Currently, gastropods are divided into six subclasses: Caenogastropoda, Heterobranchia, Neomphaliones, Neritimorpha ...

Tuning gastropod locomotion: Modeling the influence of mucus rheology on the cost of crawling [PDF]
Common gastropods such as snails crawl on a solid substrate by propagating muscular waves of shear stress on a viscoelastic mucus. Producing the mucus accounts for the largest component in the gastropod's energy budget, more than twenty times the amount ...

Sialic acids in gastropods [PDF]
The occurrence of N‐acetylneuraminic acid and N‐glycolylneuraminic acid residues in preparations of the slug Arion lusitanicus (Gastropoda) was determined by sodium dodecyl sulphate electrophoresis of the proteins followed by lectin blots stained with the sialic acid specific lectin from Maackia amurensis, by the sensitivity of this binding to ...

The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches.

High bioaccumulation of cadmium and other metals in Patagonian edible gastropods [PDF]
High concentrations of metals are accumulated by edible marine resources, affecting human health. Marine gastropods have been commercially captured and consumed in Argentina for decades without official regulations or studies to guarantee their safety ...

The effect of temperature, soil nitrogen and gastropods on _Thuja plicata_ growth and reproduction [PDF]
Humans are changing the environment. For example, nitrogen deposition, rising temperatures, and non-native species are influencing plant communities. These changes have and will continue to affect trees, thus, understanding the response of species to ...
