Resumen:

Main physiological functions such as cell proliferation, metabolism, growth, immune response, reproduction, and behaviors follow a circadian rhythm. These regular oscillations require their orchestration in order to gain in homeostasis and health, and the temporal coordination of these depends on reciprocal signaling among the hierarchically organized oscillating structures. The generation of circadian rhythms is determined by a self-sustained program of genetic expression denominated the circadian clock. The burrower crayfish Procambarus acanthophorus spends long periods building deep tunnels to reach the water table during the dry season, and its digging behavior follows a nocturnal circadian rhythm. Thus, this species has a close relationship with the soil, and the properties of this abiotic factor exert a deep influence on the life history of P. acanthophorus, determining its population dynamic; additionally, it impacts physiological processes such as the parameters of its circadian behaviors. In this regard, soil could comprise for this burrower an ecological factor with high perceived value that influences ecological aspects, but also physiological functions such as growth, reproduction, and organization of the circadian system. Apparently, all of these induced effects depend on modification of the genetic program that establishes the temporal coordination of circadian rhythms in P. acanthophorus. © 2018 Nova Science Publishers, Inc.
