| Аннотация |
Gonatus fabricii is the most abundant cephalopod species in Arctic waters, and the only squid that completes its entire life cycle there. In order to understand its ecological role in the
Arctic, we conducted stable isotope analyses of beaks from all ontogenetic groups from west and east Greenland waters and the Barents Sea, complemented with morphological data. The values
of both δ13C and δ15N of G. fabricii were not related to sex. Values of δ13C showed a small ontogenetic increase, and these values were geographically distinct, with highest levels found in the
western part of the study area. Values of δ15N showed a dramatic ontogenetic increase (i.e. 10.0? δ15N; 2.6 trophic levels), from epipelagic juvenile forms to large bathypelagic adults, without significant
geographical variation. The observed maximum value of δ15N (14.9 ?) is the highest ever recorded in cephalopod beaks. The estimated trophic level (up to 5.1) compares only to top vertebrate
predators in the Arctic |
