We used Generalized Additive Models and satellite environmental data. Mainly sea surface temperature, but also currents, surface height, and primary production were significantly correlated with both species’ early stages distributions. Anchovy optimal temperature upper limit was not detected, but sardine eggs and larvae presented a small-ranged bell-shape curve relationship to SST with an upper SST threshold around 13 °C. Sardine spawning during winter appeared to be dependant not only on in-situ environmental conditions but also on summer conditions prior to the spawning event. Model predictions of the larval and spawning habitat distribution showed clear differences between developmental stages and between species, confirming a worsening of the sardine habitat with time. Considering the further increase of surface temperature predicted in the years to come, the survival of the sardine in the region could be compromised | Descripción: | 12 pages, 3 figures, 3 tables, supplementary data https://doi.org/10.1016/j.marenvres.2021.105381 | Versión del editor: | https://doi.org/10.1016/j.marenvres.2021.105381 | URI: | http://hdl.handle.net/10261/245804 | DOI: | 10.1016/j.marenvres.2021.105381 | ISSN: | 0141-1136 |
