Molecular diversity and selective sweeps in Iberian honey bee
Muñoz, Irene; Henriques, Dora; González-Veiga, Manuel; Chávez-Galarza, Julio; Pinto, M. AliceDeciphering the genetic basis of the process of adaptation of organisms has been and remains one of the fundamental goals of evolutionary biology. Genomes contain information related to the history of natural populations. The Iberian honey bee (Apis mellifera iberiensis Engel 1999) exhibits a complex genetic diversity pattern of clinal variation shaped not only by evolutionarily neutral processes but also by se...
A novel SNP-based tool for estimating C-lineage introgression in the dark honey...
Pinto, M. Alice; Henriques, Dora; Browne, Keith A.; Barnett, Mark W.; Parejo, Melanie; Kryger, Per; Freeman, Tom C.; Muñoz, Irene; Garnery, LionelThe natural distribution ofthe honeybee (Apis mellifera L.) hás been changed by humans in recent decades to such an extent that the formerly widest-spread European subspecies, Apís mellifera mellifera, is threatened by extinction through introgression from highly divergent commercial strains in large tracts of its range. Conservation efforts for A. m. mellifera are underway in multiple European countries requir...

Polymorphisms in cytochrome P450 versus cline distribution of evolutionary line...
Muñoz, Irene; Henriques, Dora; De la Rúa, Pilar; Pinto, M. AliceHoney bees (Apis mellifera) are the most prominent and economically important pollinator species worldwide. However, the reported decline of its populations in several regions of the world over the last decades is of concern. The causes are manifold, including the spread of pathogens and parasites, malnutrition and habitat loss, climate change and xenobiotics, especially pesticides. Among the main mechanisms us...

Modulación de la diversidad genética de Apis mellifera iberiensis por xenobióticos
Muñoz, Irene; Henriques, Dora; De la Rúa, Pilar; Pinto, M. AliceDescifrar la base genética de la resistencia metabólica de los polinizadores ante xenobióticos es uno de los retos primordiales en el contexto actual de "crisis ambiental global". Esta cuestión es fundamental para uno de los polinizadores más importantes: la abeja de la miel Apis mellifera. El reciente declive de sus poblaciones está siendo ampliamente estudiado y entre sus causas se incluyen factores como los ...
SNP assay validation in honey bee populations and allele frequency determinatio...
Muñoz, Irene; Martín-Hernández, Raquel; Higes, Mariano; De la Rúa, Pilar; Pinto, M. AliceSingle nucleotide polymorphisms (SNPs) have a great potential in genetic identification and introgression studies of honey bees (Apis mellifera). To achieve SNPs full power in genetic analysis, they must be screened in a rapid, accurate and cost-effective manner. Matrix-assisted laser desorption-ionization–time-of-flight (MALDI–TOF) mass spectrometry is a promising tool for the high-throughput screening of SNPs...

Muñoz, Irene; Henriques, Dora; Jara, Laura; Johnston, J. Spencer; Chávez-Galarza, Julio; De la Rúa, Pilar; Pinto, M. AliceThe honeybee (Apis mellifera) has been threatened by multiple factors including pests and pathogens, pesticidesand loss of locally adapted gene complexes due to replacement and introgression. In western Europe, the geneticintegrity of the native A. m. mellifera (M-lineage) is endangered due to trading and intensive queen breeding withcommercial subspecies of eastern European ancestry (C-lineage). Effective cons...
Spatial genetic structure in the saddled sea bream (Oblada melanura [Linnaeus, ...
Calò, Antonio; Muñoz, Irene; Pérez-Ruzafa, Ángel; Vergara-Chen, Carlos; García-Charton, José AntonioMarine protected areas (MPAs) and networks of MPAs are advocated worldwide for the achievement of marine conservation objectives. Although the knowledge about population connectivity is considered fundamental for the optimal design of MPAs and networks, the amount of information available for the Mediterranean Sea is currently scarce. We investigated the genetic structure of the saddled sea bream ( Oblada melan...
