Erratum to: Latitudinal dependence of body condition, growth rate, and stable isotopes of juvenile capelin ( Mallotus villosus ) in the Bering and Chukchi Seas

Capelin occupy a key trophic role and have a broad latitudinal distribution in the northeastern Pacific and Arctic Oceans. Understanding their adaptation to a range of conditions is important to predicting how they will respond to climate change. To quantify the variation in body condition in different physical environments, we measured energy density, RNA/DNA ratios, carbon and nitrogen stable isotope ratios in 62 juvenile capelin along the Western Alaskan coast from Bristol Bay to Point Barrow ranging across approximately 14° of latitude. Energy density correlated positively with latitude, whereas RNA/DNA (instantaneous growth index) was strongly correlated with sea surface temperature, indicating that optimal growth of capelin was achieved at ~9 °C, followed by rapid decreases in RNA/DNA ratios at higher temperatures. δ 13 C and δ 15 N had strong, inverse nonlinear relationships with latitude. Depletion of δ 13 C seen in capelin North of Bristol Bay may be related to the incorporation of allochthonous basal resources into the diets of juvenile capelin from nearby riverine inputs. Observed enrichment of δ 15 N North of Bristol Bay is likely to be related to incorporation of higher trophic level prey items. Given inverse relationship between δ 13 C and δ 15 N, these prey items are likely available due to the increased diversity of basal resources from increased inputs of riverine organic material.
