Central de combustión interna Guerrero Negro IV

El proyecto tiene por objeto describir un proceso de licitación pública ofrecido por la Comisión Federal de Electricidad de México para satisfacer la demanda de electricidad en Baja California Sur. Para realizar este proyecto, se han estudiado las mejores opciones para poder diseñar y construir en el futuro cercano una planta basada en un motor de combustión interna de 6,54 MW. También se ha realizado un estudio económico de coste de capital y explotación de la central, donde se tendrá en cuenta la totalidad de gastos y costes generados por la misma, estableciendo un valor de coste/unidad eléctrica generada.

Trans-Pacific migrations of the loggerhead turtle (Caretta caretta) demonstrated with mitochondrial DNA markers.

Juvenile loggerhead turtles (Caretta caretta) have recently been documented in the vicinity of Baja California and thousands of these animals have been captured in oceanic fisheries of the North Pacific. The presence of loggerhead turtles in the central and eastern North Pacific is a prominent enigma in marine turtle distribution because the nearest documented nesting concentrations for this species are in Australia and Japan, over 10,000 km from Baja California. To determine the origin of the Baja California feeding aggregate and North Pacific fishery mortalities, samples from nesting areas and pelagic feeding aggregates were compared with genetic markers derived from mtDNA control region sequences. Overall, 57 of 60 pelagic samples (95%) match haplotypes seen only in Japanese nesting areas, implicating Japan as the primary source of turtles in the North Pacific Current and around Baja California. Australian nesting colonies may contribute the remaining 5% of these pelagic feeding aggregates. Juvenile loggerhead turtles apparently traverse the entire Pacific Ocean, approximately one-third of the planet, in the course of developmental migrations, but mortality in high-seas fisheries raises concern over the future of this migratory population.
