Disentangling the influence of fishing, demography and environment on population dynamics of Iberian Peninsula waters fish stocks

Overexploitation and climate change are increasingly causing unanticipated changes in marine ecosystems such as higher variability in fish recruitment or shifts in species dominance and distribution that alter the productivity of fish stocks. This study analyses how external and internal drivers inf...
