Fisheries management often relies on single‐species assessments, overlooking multispecies dynamics while facing the added challenge of nonlinear environmental variability. Marine landings of most commercially exploited species in the Southwestern Atlantic have declined for decades and are projected to decrease further under climate change, as ocean warming is expected to reduce fisheries catches and revenues. Despite these tre...

The reproductive cycle of seven common species ( Gobius paganellus , Gobius bucchichi , Gobius cobitis , Parablennius sanguinolentus , Salaria pavo , Tripterygion tartessicum and Symphodus roissali ) on rocky shores in the Gulf of Cadiz and their relationship with the sea surface temperature (SST) is analysed. Partial data on Scorpaena porcus are also given. Fecundity of these short lifespan species shows a positive linear cor...
