| description |
Physiological responses of marine organisms are influenced by environmental variations, particularly in dynamic habitats. These variations could be at a diel or seasonal scale and require acclimation responses that, at a molecular level, are facilitated by gene expression regulation. Circadian rhythms allow organisms to adjust to recurring environmental changes and to synchronize physiological processes. Increased Hsp70 gene expression allows organisms to protect themselves against heat and other stressors, conferring them a periodically changing thermotolerance. This study aimed at analyzing whether the variability of exogenous factors (temperature, dissolved oxygen, salinity) in diurnal or seasonal scales affects hsp70 expression in cryptic reef fishes in their natural environment. The study model was Lythrypnus dalli, an endemic cryptic reef fish inhabiting shallow waters throughout the Gulf of California. Physical parameters varied seasonally; temperature increased 6°C during the warm season, salinity and dissolved oxygen remained constant. Minimal changes in temperature (±1 °C) occurred diurnally. Expression levels of hsp70 increased significantly during the warm season (p < 0.05), perhaps related to seasonal thermal changes. No differences in hsp70 were observed during the diurnal cycle (p > 0.05). L. dalli has apparently developed phenotypic plasticity to face environmental variability at diurnal and seasonal scales. |

Las respuestas fisiológicas de los organismos marinos son influenciadas por variaciones ambientales, particularmente en hábitats dinámicos. Éstas pueden ser a escala diurna o estacional y requieren respuestas que, a nivel molecular, son facilitadas por inducción de expresión génica. Los ritmos circadianos permiten ajustar cambios ambientales recurrentes y sincronizarlos con procesos fisiológicos. El incremento en la expresión de hsp70 es una estrategia para enfrentar cambios térmicos y otros estresores, confiriendo termotolerancia que cambia periódicamente. El objetivo de este estudio fue analizar si la variabilidad de factores exógenos (temperatura, oxígeno disuelto, salinidad) en escalas diurna o estacional afecta la expresión de hsp70 en peces crípticos en su medio natural. El modelo de estudio fue Lythrypnus dalli, un pez críptico arrecifal que habita el Golfo de California. Los parámetros físicos variaron estacionalmente; la temperatura aumentó 6°C durante la temporada cálida, salinidad y oxígeno disuelto permanecieron constantes. Se observaron cambios mínimos (±1°C) en temperatura en el ciclo diurno. Los niveles de expresión de hsp70 aumentaron durante la estación cálida (p < 0.05). No se observaron diferencias en hsp70 durante el ciclo diurno (p > 0,05). L. dalli aparentemente ha desarrollado plasticidad fenotípica para enfrentar la variabilidad ambiental diurna y estacional.
