Can stochastic variations in recruitment induce long-term fluctuations in the carrying capacity?
Provedor de dados: 5
Autores: Fromentin, Jean-marc.
Long-term fluctuations in fish abundance are generally attributed to low frequency processes, such as human exploitation and/or environmental and climatic changes. Based on recent studies and simple simulations, this manuscript shows how long-term fluctuations in the carrying capacity and/or spawning stock biomass of a long-live species, such as the Atlantic bluefin tuna, may simply arise from stochastic variations in the recruitment. The implications of such a feature are discussed and compared among different Atlantic tunas and tuna-like species.
