The population structure of North African A. mellifera subspecies has been overlooked. Here, WG generated from drones were analyzed to assess population structure and the conservation status of three A-lineage subspecies: A. m. lamarckii (Egypt, 68 samples), A. m. intermissa (Algeria, 69 samples), and A. m. sahariensis (Algeria, 68 samples; Morocco, 26 samples). Population structure was assessed by SNMF and PCA...

Honey is highly susceptible to adulteration. Currently, the assessment of its geographical origin remains one of the most difficult tasks, which is typically performed by melyssopalynology. Recently, the attention has shifted towards indirect approaches such as the entomological origin based on geographical distribution patterns of honey bee subspecies. Although queens’ trade has impacted the natural subspecies...

A abelha melífera, Apis mellifera, é composta por 31 subespécies que se encontram distribuídas na Ásia, África e Europa. O objetivo deste trabalho é desvendar a estrutura populacional e verificar o estado de conservação de três subespécies do Médio Oriente, as quais têm sido pouco estudadas. Para isso, foi extraído o DNA a partir de tóraxes inteiros de machos de 329 amostras de A. m. lamarckii (Egito, 68 amostr...

Beekeeping is an ecologically and economically important activity in the Mediterranean that is increasingly under threat from a combination of factors. In the MEDIBEES (Monitoring the Mediterranean honey bee subspecies and their resilience to climate change for the improvement of sustainable agro-ecosystems) PRIMA project we aim to identify honey bees that show resilience to stressors associated with climate ch...
