Causal drivers of Barents Sea capelin (Mallotus villosus) population dynamics on different time scales
Abstract The dynamics of marine populations are usually forced by biotic and abiotic factors occurring at different intensity levels and time scales. Deriving the time frame within which each factor has a causal influence is important for predicting population trajectories. This paper presents a sta...
