Understanding the genetic mechanisms of adaptive population divergence is one of the most fundamental endeavours in evolutionary biology and is becoming increasingly important as it will allow predictions about how organisms will respond to global environmental crisis. This is particularly important for the honey bee, a species of unquestionable ecological and economical importance that has been exposed to incr...
La península ibérica es conocida como un importante foco (hotspot) de diversidad y endemismos de numerosas especies de plantas y animales representando por ello una de las regiones prioritarias por la conservación en Europa. Varios factores geomorfológicos y ambientales contribuyen a esta riqueza, concretamente: la localización geográfica en el extremo sudoeste de Europa, el aislamiento en relación al resto de...
The Iberian honey bee (Apis mellifera iberiensis) has been intensely surveyed for genetic variation with different markers ranging from morphology, allozymes, mitochondrial DNA (mt DNA), to microsatellites. Some of these markers have revealed non-concordant complex patterns of genetic variation, which led scientists to evoke competing hypotheses for the origin of Iberian honey bees. While complex patterns and u...
Estudios explorativos del genoma se ha convertido en un abordaje popular para detectar selección permitiendo un análisis de la adaptación local y especiación a nivel molecular en poblaciones. La abeja ibérica (Apis mellifera iberiensis) ha sido estudiada con una variedad de marcadores genéticos como alozimas, DNA mitocondrial y microsatélites, pero estos han revelado complejos patrones y procesos que aún deben ...
A conservação da diversidade genética das populações locais de abelhas é fundamental à sustentabilidade da actividade apícola. Em primeiro lugar, porque a diversidade genética é a matéria-prima sobre a qual a selecção (natural ou artificial) actua, permitindo a adaptação das abelhas às cada vez mais rápidas alterações ambientais (pesticidas, novos patogénios e parasitas) e às exigências de uma actividade apícol...
Over the last 20 years Iberian honey bees (IHB) have been scrutinized with a variety of genetic markers including morphology, allozymes, mtDNA, and microsatellites. The complex patterns and processes revealed have yet to be fully understood. While mtDNA is useful to reveal the maternal component, biparental markers capture genome-wide effects (admixture, expansions, and contractions) and locus-specific effects ...
Genome scans with many genetic markers provide the opportunity to investigate local adaptation in natural populations and identify candidate genes under selection. The recent advent of high-throughput Single Nucleotide Polymorphism (SNP) genotyping technologies have opened new perspective of research and these markers are commonly observed in functional genes making them ideal markers to study adaptive molecula...

Dissecting genome-wide (expansions, contractions, admixture) from genome-specific effects (selection) is a goal of central importance in evolutionary biology because it leads to more robust inferences of demographic history and to identification of adaptive divergence. The publication of the honey bee genome and the development of high-density SNPs genotyping, provide us with powerful tools, allowing us to iden...
The Iberian Peninsula has been recognized as a hot spot of diversity and endemisms for numerous plant and animal species, and the honeybee is no exception. Honeybees occur naturally in Europe, Africa and the Middle East. In this vast range of habitats, adaptation to the diverse ecological conditions has led to evolution of over 29 subspecies, which have been grouped into five lineages. The Iberian Peninsula har...
