From the Adriatic to Northern Norway—geographic differences in moult increment and moult probability of the European lobster ( Homarus gammarus ), across the natural range
Abstract This study collated existing data on lobster moult increment from studies across the range of Homarus gammarus, together with new tagging data from Orkney, United Kingdom. Generalized additive models were used to investigate geographical differences in absolute moult increment and moult pro...
