| ABSTRACT Lionfish was studied in the mesophotic environment. 237 specimens were observed, most in the upper mesophotic zone. Males were larger than females and differences between sexes in growth models were found. Sixteen prey items were identified, the most important being the teleost families Acanthuridae and Monacanthidae, and the crustacean Penaeidae. The mean of δ13C was -17.08 ± 0.36 ‰ and δ15N was 8.68 ± 0.46 ‰, with no differences between sexes. Lionfish occupies a less extensive isotopic niche in mesophotic environment than in shallow sectors; there is an isotopic niche overlap between sexes. Likewise, lionfish has specialized trophic habits. All specimens were mature and in females regression phase predominated. In females, condition factor... |

| Continuous measurements were taken of oceanographic and meteorological parameters for two stations of the Global Ocean Observing System of the Southwest Caribbean, framed in the INAP project. The response of the surface layer, to atmospheric events, allowed to differentiate the pass of two cold fronts by Johnny Cay station (San Andres Island) and the arrival of the "Veranillo" in the sensors of Tesoro Island (Islas del Rosario, Cartagena). The cold fronts produced a decrease in the atmospheric pressure, air temperature, caused radical changes in wind direction and speed followed by precipitation. This situation lowered the sea surface temperature, the surface layer pH and rose momentarily the sea level. The "Veranillo" came to Archipelago of Rosario... |
