(Peer reviewed; Journal article, 2023)Demographic correlations are pervasive in wildlife populations and can represent important secondary drivers of population growth. Empirical evidence suggests that correlations are in general positive for long-lived ... -
Eyes on the future: buffering increased costs of incubation by abandoning offspring
Hanssen, Sveinn Are; Erikstad, Kjell E.; Sandvik, Hanno; Tveraa, Torkild; Bustnes, Jan Ove (Peer reviewed; Journal article, 2023)Life history theory states that the resources invested in current reproduction must be traded off against resources needed for survival and future reproduction.
