Microhabitat distribution, shell shape, and metabolomes in sympatric populations of closely related species of the genus Littorina (Neritrema) in two sites in the Norwegian and Barents Sea

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 comp...

Description
Summary: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).
