“…Introduction events can be detected by the presence of haplotypes more frequently observed in A. m. ligustica colonies (Franck et al ., b; Dall'Olio et al . ), which are thus considered to be foreign in Sicilian honey bee colonies.…”

Apis mellifera siciliana is a honey bee subspecies prone to be conserved. Conservation measures include maintaining colonies on different islands to serve as parental lines for outcrossing. Molecular diversity and genetic structure of honey bees from Sicily (main island) and Vulcano and Filicudi (conservation islands) were analysed with mitochondrial and microsatellite markers to assess the efficacy of the ongoing conservation effort. Samples from continental Italy and Sardinia island were included for comparison. All the samples of the conservation islands were included in the African (A) evolutionary lineage, while western and northern (M) and eastern (C) European evolutionary lineages were also detected in colonies from the main island (17.1% and 22% respectively), thus highlighting introgression at the mitochondrial level. Nuclear data from conservation and main island populations were compared to evaluate the proportion of admixed honey bees. A higher level of hybridization was found in the central and eastern areas of Sicily main island. Our data describe the efficacy of the conservation islands, and suggest where and how to manage mating stations to further improve the present conservation strategy by recovering additional residual genetic variability of A. m. siciliana. We also propose the establishment of a European network of conservation islands to preserve honey bee subspecies and to implement research studies of adaptation to peculiar climatic conditions.

“…Spanish honeybee populations are the most studied with these molecular markers (Franck et al, 1998;Garnery et al, 1998b;De la Rúa et al, 2002a;Miguel et al, 2007). Italian honeybees have also been intensively analysed due to the frequent exportation of A. m. ligustica queens (Franck et al, 2000aDall'Olio et al, 2007). Other studies on microsatellite variation in honeybee populations from Slovenia (Sušnik et al, 2004), Cyprus (Kandemir et al, 2006) and Turkey (Bodur et al, 2007) demonstrate their usefulness to detect recent events such as introduction of foreign subspecies and ensuing introgressive hybridization.…”

-Europe harbours several endemic honeybee (Apis mellifera) subspecies. Yet the distribution of these subspecies is nowadays also much influenced by beekeeping activities. Large scale migratory beekeeping and trade in queens, coupled with the promiscuous mating system of honeybees, have exposed native European honeybees to increasing introgressive hybridization with managed non-native subspecies, which may lead to the loss of valuable combinations of traits shaped by natural selection. Other threats to European honeybees are factors that have caused a progressive decline in A. mellifera throughout the world in recent years, leading to large economic losses and jeopardizing ecosystem functioning. We review the biodiversity of European honeybees and summarize the management and conservation strategies employed by different countries. A comprehensive picture of the beekeeping industry in Europe is also provided. Finally we evaluate the potential threats affecting the biodiversity of European honeybee populations and provide some perspectives for future research.Apis mellifera / subspecies / biogeography / conservation / Europe / beekeeping

“…Four out of the five mitochondrially characterized evolutionary lineages are endemic around the Mediterranean Basin (Garnery et al, 1993;Arias and Sheppard, 1996;Franck et al, 2000aFranck et al, , 2001Miguel et al, 2007;Cánovas et al, 2008): Several contact areas have been detected with the analyses of allozymes, mitochondrial and microsatellite data: in the Iberian Peninsula between the lineages A and M (Garnery et al, 1995;Smith and Glenn, 1995;Franck et al, 1998;De la Rúa et al, 2002;Miguel et al, 2007;Cánovas et al, 2008) and in the Alpine ridge between lineages M and C (Franck et al, 2000a;Dall 0 Olio et al, 2007). The transition from lineage C to O has been identified in Turkey (Kandemir et al, 2006).…”

Apis mellifera evolutionary lineages in Northern Africa: Libya, where orient meets occident

The distribution of various evolutionary lineages of Apis mellifera subspecies in Africa is still controversial. We sampled honeybees from eight coastal locations and three Saharan oases in Libya and analyzed mtDNA variability with restriction fragment length polymorphisms and the sequence of the tRNAleu-cox2 intergenic region. Haplotypes belonging to the oriental O evolutionary lineage, including four which are newly described, were detected in all investigated locations. Haplotypes belonging to the European M lineage were rarely detected, probably reflecting the effect of sporadic importations. Honeybees belonging to the A lineage were detected in Al Aziziyah and Zlitan close to the Tunisian border. The distribution of the O lineage extends westward up to the border between Libya and Tunisia, a contact area between the O and A lineages. Various Libyan honeybee populations in Saharan oases are characterized by novel and unique haplotypes (O4, O5, O5 0 and O5 00 ). These might be natural relic populations that became isolated when the North African Sahara desert was still grassland (0.126-0.168 Myr ago).
