AbstractThe phylum Labyrinthulomycota comprises diverse marine fungus-like protists that are an abundant and widespread component of the marine microbiota. Despite their ubiquity in marine ecosystems, relatively little is known about the ecology of any of the pathogenic species in the Labyrinthulomycota. Most are thought to exist as saprobes, but many species have been documented as pathogens of marine metazoans and metaphytes. The best studied labyrinthulomycotan pathogen in molluscs is Quahog Parasite Unknown (QPX), which causes mortality events in both wild and cultured hard clams,

Investigations of the Middle-Late Neopleistocene deposits of the Kosika 1 locality and studied malacological complexes permit to understand changes of the main geological events of the territory and to identify molluscs palaeoecologihal habitats. Brakishwater and freshwater lakes existed on the territory after Early Khazarian Sea regression (beginning of the Late Neopleistocene; layer 1). Marine deposits accumulated during Late Khazarian Sea transgression (first half of the Late Neopleistocene; layer 2). Big river (Paleo-Volga) existed after the regression of the Late Khazarian Sea. This river flow to the south in the direction of the coastline retreatment. Fluvial deposits prove river existence (layer 4). Marine deposits with special key mollusc species accumulated during the Khvalynian Sea transgression. Again, river existed after regression of this sea. Alluvium is on the top of the Khvalynian section, it is contain rich complex of the freshwater and marine mollusc species (layer 5). Fluvial-marine deposits form the underwater delta, which accumulated during Late Khvalynian time. These deposits contain shell fragments of freshwater and marine mollusc species. Deposits of the underwater delta form in the relief elongated hills, which are known as Ber bugor among geomorphologists.

Cham Islands (Cu Lao Cham) is a group of 8 small islands in the Quang Nam province, Central Vietnam. There is only one study that mentioned the diversity of marine molluscs in this area. However, the data on species composition have not been digitised and not stored or shared for other purposes. Our paper aims to share the checklist of marine mollusc species (Bivalvia and Gastropoda) species that we collected from the littoral zone of Cham Islands in May 2017. This is the first digitised and online data of marine molluscs in Vietnam. It is very important for researchers in various fields such as the structure and function of ecology and biodiversity monitoring. This study provides a checklist of the marine bivalves and snails in the Cham Islands of Vietnam. Moreover, this first widely shared data of biodiversity in Vietnam can trigger biodiversity data papers in this data-poor country. The data of this study will be important inputs for better understanding biodiversity on the Cham Islands and Vietnam as well as for forming the basis for monitoring, exploitation and conservation of biodiversity in this area. In total, 145 taxa were recorded, 46 bivalve taxa and 99 snail taxa, from which 128 were identified to the species level and 17 were identified to the genus level. There are 116 new species records for the Cham Islands. The specimens are currently deposited in the Institute of Ecology and Biological Resources (IEBR), Vietnam Academy of Science and Technology (VAST).
