Abstract:

Abstract Anthropogenic impacts lead to a decrease in the abundance and diversity of communities of living organisms. The rate of recovery of populations is inversely proportional to size: the smaller the size, the greater the potential for population recovery after negative impact. Therefore, under conditions of extremely high levels of anthropogenic impact, small-sized animals are a reliable source of ecosystem state. The aim of the work is to: 1) to evaluate rates of the micromollusc Vallonia pulchella (Müller, 1774) abundance in ecosystems that are subject to extremely high levels of recrea

Abstract:

Micromolluscs comprise a signifi cant proportion of terrestrial malacofaunas in the tropics. As such, inventories and ecological sampling protocols must endeavor to maximize the capture of micromolluscs. Sampling protocols (i.e., appropriate number of sampling plots) for micromolluscs, however, still require refi nement to improve sampling effectiveness. Apart from describing our recommended sampling protocols for micromolluscs, we compared completeness ratios (as a proxy for sampling effectiveness) and species densities and diversities across different vegetation types (i.e., limestone karst

Abstract:

Studies of micromolluscs are essential in the malacology of the 21st century. Our understanding of molluscs has been chiefl y based on large-sized species, and there are little-known taxa that comprise only of small-sized species. In Japan, an obvious change occurred from classic conchology to more advanced microscopic work in the 1990s, but further research must be accelerated to reveal the entire fauna. In this review, a summary of the current state of knowledge is given for all known micromolluscan families distributed in Japan. Since the 1990s new micromolluscs have been described from var

Abstract:

The use of molecular techniques is pervasive in contemporary systematics. We stress the importance of depositing voucher material, particularly for the less well-known micromolluscs, along with images from which specimens can be identifi ed. Appropriate storage is paramount to ensure long-term survival of those voucher specimens. We detail methods of animal extraction that retain the shell as a voucher specimen, and detail salvage of radula and operculum from DNA spin columns. DNA can be extracted from freshly collected micromolluscs, but most dry and wet material in museum collections is not

AbstractCorrelation of lower Cambrian strata is often confounded by provincialism of key fauna. The widespread occurrence of the micromollusc Watsonella crosbyi Grabau, 1900 is therefore an important biostratigraphic signpost with potential for international correlation of lower Cambrian successions. Previous correlations of W. crosbyi from Australia (Normanville Group) suggested an Atdabanian- to Botoman-equivalent age. However, in the upper part of the Mount Terrible Formation, stratigraphic ranges of W. crosbyi and Aldanella sp. cf. golubevi overlap prior to the incoming of vertically burro

Abstract:

The biodiversity of molluscs is highly threatened in marine, terrestrial and freshwater ecosystems worldwide. This research aimed at studying the distribution and conservation status of eight poorly-known micro-snails of the genera <i>Stephacharopa</i> and <i>Stephadiscus</i> in Chile. We performed a comprehensive review of literature and databases to determine the occurrences of the species, which were mapped on vector layers containing protected areas and human development infrastructure to find potential threats. Conservation status assessment was performed following the criteria and tools

Abstract:

In this study, Stenothyra glabra belonging to the truncatelloid family Stenothyridae is redescribed using morphological characters from the shell, operculum, and radula. The species is distinguished from other species in the group by its shell without spotted spiral lines and by its dome-shaped, mostly smooth, protoconch with some pits. Together with the morphological description, the complete mitogenome for the species is provided, which fill a knowledge gap in Stenothyridae. The mitogenome of S. glabra is 15,830 bp in length and has a circular structure. It contains 37 genes: 22 transfer RNA

After an extensive search for the type specimens of Caecum floridanum Stimpson, 1851, we believe that these specimens may have been either lost or destroyed in the Chicago fire (1871). This paper presents a redescription of the species and a neotype is designated based on material from the type locality (Florida). Protoconch and growth stages of C. floridanum are described and illustrated herein. The teleoconch IV of C. floridanum is characterized by strong, wide, low, rounded, closely arranged axial ribs, except last three to four preceding the aperture, which are larger and more widely separ

For the purpose of this volume, micromolluscs were defi ned as molluscs no larger than 5 mm. Such forms play an important role in a variety of research fi elds, such as origin, phylogeny or biodiversity of the phylum. It is widely recognized that the small molluscan fauna is incredibly diverse and replete with signifi cant discoveries to be made, yet few people work

Abstract:

The diversity of the sedimentary environment and molluscs is rich in the intertidal zone of the Yellow Sea and Bohai Sea. At present, many of the investigations focus on macromolluscs, while the diversity of micromolluscs is seriously underestimated. In this study, the survey of micromolluscs was carried out in the intertidal zone of the Yellow Sea and Bohai Sea. The collection and preservation of micromolluscs, as well as the preparation methods of morphological characteristic structures by scanning electron microscopy (SEM) were explored. A total of 20 species were described in this survey.

Abstract:

Micromolluscs are small-sized molluscs (< 5 mm), and include the great majority of undescribed molluscan taxa. Such species require special collecting, sorting and handling techniques and different storage requirements to those routinely used for larger specimens. Similarly, the preparation of shells, opercula, radulae and animals poses some challenges for scanning electron microscopy (SEM). An overview of experiences with various techniques is presented, both positive and negative. Issues discussed include those relating to storage of dry specimens and interaction of specimens with glass,

Abstract:

X-ray micro-CT is demonstrated to be a novel technique to examine soft-tissue anatomy and is used here to reconstruct images of molluscan soft-tissue for the first time. Two micromolluscs ( 1.8 mm diameter) were imaged using micro-CT, and then reconstructed to form 3D models of the tissues. Discrete organs of the alimentary system of large gastropods were also imaged. Osmium tetroxide and phosphomolybdic acid were identified as useful stains and a specimen preparation protocol is presented. Micro-CT is a rapid, non-destructive technique which complements and may in some circumstances replace t

Abstract:

Marine mollusks provide important ecosystem services. They create habitats for benthic organisms, filter water, biodeposit organic carbon in the seafloor, and serve as food sources for other organisms. Studies of mollusk diversity require time-consuming methods to process samples and identify species. Thus, it is not surprising that most studies have focused on macromollusks that can be collected and processed easily, ignoring micromollusk species. Without understanding the ecology and distributions of micromollusks properly, it is impossible to assess their populations and implement adequate

Abstract:

ABSTRACTMollusca, the second‐most diverse animal phylum, is estimated to have over 100,000 living species with great genetic and phenotypic diversity, a rich fossil record, and a considerable evolutionary significance. Early work on molluscan systematics was grounded in morphological and anatomical studies. With the transition from oligo gene Sanger sequencing to cutting‐edge genomic sequencing technologies, molecular data has been increasingly utilised, providing abundant information for reconstructing the molluscan phylogenetic tree. However, relationships among and within most major lineage

Abstract:

ABSTRACT Shell images in digital collections and publications enable taxonomically, geographically and morphologically broad approaches to studying gastropod body size. Because traditional linear size measurements are not directly comparable across morphologically disparate taxa, we propose a transition to landmark-based size measurements, which are less sensitive to shape differences. Traditional and landmark-based size measurements were compared using two study systems: 36 specimens of diplommatinid micromolluscs from the Belau archipelago and 66 marine, freshwater and terrestrial gastropod
