This study is devoted to microevolutionary processes in populations of marine snails of subgenus Neritrema (Gastropoda, Littorinidae). We analyzed the microhabitat distribution of 5 cryptic species of molluscs (Littorina saxatilis (Olivi, 1792); Littorina arcana Hannaford Ellis, 1978; Littorina compressa Jeffreys, 1865; Littorina obtusata (Linnaeus, 1758); Littorina fabalis (Turton, 1825)) within the intertidal zone and potentially related morphological and physiological characteristics. The data was collected at two geographic locations (Saltstraumen, Norwegian Sea, 66°58'10.2"N 13°58'26.5"E, collection dates 29.06-5.07.2019; Varangerfjord, Barents Sea, 70°04'03.9"N 29°58'40.1"E, collection dates 09.07-12.07.2019).Additional information may be found in the mentioned paper.
ACKNOWLEDGMENTSThe project was supported by the Russian Scientific Foundation grant 19-14-00321, PI Andrey Granovitch. Metabolomics analysis was performed by the equipment of the Resource Center of St. Petersburg State University “Development of Molecular and Cell Technologies”. Adaptation of the GC-MS protocol for the TMS-analysis and in-house database were made during the realization of the BIN research project АААА-А18-118032390136-5 “Assessment of changes in the correlation structure of metabolic networks in the process of growth and development of fungi and plants from the viewpoint of systemic biology.”
