Última Reproductive investment in Atlantic cod populations off Newfoundland: Contrasting trends between males and females ArchiMer Baulier, Loic; Morgan, M. Joanne; Lilly, George R.; Dieckmann, Ulf; Heino, Mikko. Life history theory predicts selection for higher reproductive investment in response to increased mortality among mature individuals. We tested this prediction over the period from 1978 to 2013 for three populations of Atlantic cod (Gadus morhua) off Newfoundland. These populations were heavily fished for a long period. We considered changes in standardized gonad weight as a proxy for changes in gonadal investment. We accounted for the allometry between gonad and body weight, individual body condition, water temperature, and potential spatial and density-dependent effects. Males display significant temporal trends in gonadal investment in all populations; in agreement with theoretical predictions, these trends show increased gonadal investments during the...
