This note reports a method for studying the relationship between crystals and the organic matrix in calcified structures by means of decalcification of single thin sections. The mollusc shell has been used in developing the method. Electron microscope studies of the organic matrix of the mollusc shell have been carried out by making replicas of the normal or etched shell surfaces (Gr5goire, 195...

The importance of invertebrate herbivores in regulating plant communities remains unclear, due to the absence of long-term exclusion experiments. An experiment in an English grassland involving long-term exclusions of insect and mollusc herbivores, along with rabbit fencing, showed strong, but opposing, effects of the invertebrate herbivores. Plant species richness declined and biomass increase...

As one of the essential components of the fossil record, shells of molluscs provide crucial data for taxonomic, phylogenetic or evolutionary studies. The mollusc shell has often very few discrete morphological characters, and its most important character is its three-dimensional (3-D) geometry, which is well diversified, continuous and highly integrated. However, standard morphometric methods r...

The objectives of our survey were to determine the most important environmental factors within buffer zones that influenced mollusc communities and evaluate ecological conservation value natural aquatic habitats (NAHs) support species. Analysis spatial structure catchments was based on a set landscape metrics. Land cover classes determined, radius 500 m from sampling point marked out. Mollusc s...

Morphological and molecular data of type material of the nudibranch mollusc Dendronotus primorjensis Martynov, Sanamyan, Korshunova, 2015 from the Sea of Japan are summarised and compared with those of Dendronotus dudkai Ekimova, Schepetov, Chichvarkhina, Chichvarkhin, 2016. The clear conclusion is that the latter is a junior synonym of Dendronotus primorjensis.
