Resumen

The Mexican Pacific was influenced by ‘‘La Mancha’’ and ‘‘El Niño’’, from 2014 and until 2016. The
increase in sea surface temperature influenced the feeding habits of the bat ray (Myliobatis californica)
in the northwest of Baja California Sur, Mexico. To evaluate possible changes in the diet, stomach
content analysis and analysis of stable isotopes of carbon (δ
13C) and nitrogen (δ
15N) in muscle was
performed during normal (2012 and 2013) and anomalous years (2014, 2015, and 2016). During the
normal years, the main prey was the crab Dynomene spp. (% Prey Specific Relative Importance Index
(PSIRI) = 29.3) and the stomatopod Hemisquilla californiensis (% PSIRI = 10.6). In contrast, during the
anomalous years, these preys were replaced by the pelagic red crab Pleuroncodes planipes (% PSIRI =
28.5) and peanut worms Sipunculus spp. (% PSIRI = 7.9). During normal years the median isotopic values
recorded were: δ
13C = −16.2h and δ
15N = 15.2h. During the anomalous years, δ
13C was −16.3h and
δ
15N was 15.1h. Between the different periods no trophic (p (probability) > 0.05) or isotopic overlaps
(p > 0.3) were found. The change in the diet of M. californica during the anomalous years is an
adaptive response to the increase in water temperature caused by ‘‘La Mancha’’ and ‘‘El Niño’’. The
massive presence of P. planipes on the northwest coast of Baja California Sur is associated with the
increase in water temperature, which makes P. planipes a food source for M. californica
