Diferentes 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...
The recognition that the Dark European honey bee, Apis mellifera mellifera, is increasingly threatened in its native range has led to the establishment of conservation programmes and protected areas throughout western Europe. Previous molecular surveys showed that, despite management strategies to preserve the genetic integrity of A. m. mellifera, protected populations had a measurable component of their gene p...
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...
A 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...
Beekeeping 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...
Genome-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...

Estudos prévios usando diferentes marcadores do ADN mitocondrial sugerem que a Península Ibérica tem sido uma área de contacto secundário natural entre duas linhagens divergentes de abelhas (linhagem Africana e linhagem da Europa ocidental) formando um cline com orientação sudoeste-nordeste. Porém, é provável que com a crescente intensificação da actividade apícola haja uma alteração do padrão de diversidade mo...
