  A total of 123 sheep belonging to the Djallonke, Mossi, and Burkina-Sahel breeds, along with 41 Spanish Xalda sheep were genotyped for 27 microsatellites. The pair Djallonke-Mossi had the highest between breeds molecular coancestry. Admixture analysis informed on the parental role of the Burkina-Sahel and Djallonke breeds. The Mossi breed was a hybrid population nearer to the Djallonke breed. Only half of the Mossi individuals were correctly assigned to their breed. The Burkina-Sahel and Djallonke breeds can be considered ancestrally different genetic entities. Differentiation between the Djallonke and Mossi breeds may be due to introgression of Sahelian sheep.

This article explores whether mergers and acquisitions (M&As) generate differentiated impacts on the acquiring firms’ R&D expenditures, patents granted, and product innovations. Considering M&As as a way of foreign expansion, we examine whether the technological effects differ between domestic and foreign-owned acquirers, assuming that the effects on the technological efforts and performance may differ across industries. The availability of statistical information for a stable sample of manufacturing companies in Spain during the 1990s allows us to follow a dynamic approach to the issue. Our findings confirm the existence of differentiated effects on technological inputs and outputs across industries, as well as diversity between domestic and foreign-owned firms involved in M&As.

  Upwelling events have been analyzed along the western part of the Cantabrian coast from 1967 to 2007. This analysis shows that the highest number of days under upwelling favorable conditions was observed from June to September (12–14 days per month) with a probability of finding consecutive days under upwelling favorable conditions decreasing from 47% to 17% when events between 1 and 5 consecutive days were considered respectively. This situation was also corroborated by Sea Surface Temperature data which revealed the presence of cold water over the continental shelf, near coast, associated with upwelling favorable winds. This cold water was also observed inside the estuaries located in this area. The water temperature signal measured at the inner part of the Ria de O Barqueiro (NW Iberian Peninsula) from June to September 2008 showed to be negatively correlated with the Upwelling Index calculated in front of the northern Galician coast. This correlation tends to increase as the number of lag days between both variables increases. The maximum value of − 0.8 corresponds to a lag of 5 days.
