Análisis de introgresión en Apis mellifera iberiensis y Apis mellifera mellifer...
Chavez-Galarza, Julio; Henriques, Dora; Johnston, J. Spencer; Rufino, José; Pinto, M. AliceDiferentes estudios han agrupado las subespecies de A. mellifera en cuatro linajes evolutivos basados sobre marcadores morfométricos, ecológicos, microsatélites y mtDNA: Africano (A), Medio Oriente (O), Este y Centro de Europa (C), Norte y Oeste de Europa (M). El linaje M está representado por las subespecies A. m. iberiensis y A. m. mellifera, cuya distribución es la Península Ibérica para la primera y desde l...
clOpenCL : supporting distributed heterogeneous computing in HPC clusters
Alves, Albano Agostinho Gomes; Rufino, José; Pina, António Manuel Silva; Santos, Luís PauloClusters that combine heterogeneous compute device architectures, coupled with novel programming models, have created a true alternative to traditional (homogeneous) cluster computing, allowing to leverage the performance of parallel applications. In this paper we introduce clOpenCL, a platform that supports the simple deployment and efficient running of OpenCL-based parallel applications that may span several ...

Chavez-Galarza, Julio; Henriques, Dora; Johnston, J. Spencer; Azevedo, João; Rufino, José; Costa, Filipe; Pinto, M. AliceA Península Ibérica alberga a maior complexidade e diversidade da abelha melífera na Europa, pelo que desvendar a história evolutiva da subespécie Apis mellifera iberiensis é um desafio. Com o objectivo de decifrar quais os mecanismos subjacentes a esta diversidade, diversos estudos têm sido efectuados. Estudos iniciais usando a morfologia e alozimas mostraram a existência de um gradiente desde África até ao No...
How many SNPs are needed to provide an accurate estimate of lineage C introgres...
Henriques, Dora; Chavez-Galarza, Julio; Johnston, J. Spencer; Rufino, José; Pinto, M. AliceBeekeeping activities, especially queen trading, have shaped the distribution of honey bees subspecies in Europe, which have resulted in extensive introductions of two lineage C subspecies, A. m. ligustica and A. m. carnica, into western Europe. As a consequence, replacement and gene flow between native and commercial populations have been occurring at varying levels across western European populations. Previou...

Chavez-Galarza, Julio; Henriques, Dora; Johnston, J. Spencer; Rufino, José; Pinto, M. AliceGenome-wide scan approaches to detect signatures of selection have become popular tools to study local adaptation at the molecular level and single nucleotide polymorphisms (SNPs) are seemingly the most appropriate marker for that endeavor. SNPs (i) provide a genome-wide coverage, (ii) generate high quality data, (iii) are suitable for automated high throughput technologies allowing genotyping of hundreds to th...

Henriques, Dora; Jara, Laura; Chavez-Galarza, Julio; Rufino, José; De la Rúa, Pilar; Pinto, M. AliceHuman activities have been shaping the distribution of honey bee (Apis mellifera) subspecies in Europe. In fact, during the last decades there has been an extensive introduction of the beekeepers’ favorite eastern European (lineage C) subspecies A. m. ligustica (Italian honey bee) and A. m. carnica (carniolan honey bee) into western Europe. Resulting from these introductions, there has been gene flow, and in so...
