Genetic integrity of the Dark European honey bee (Apis mellifera mellifera) fro...
Pinto, M. Alice; Henriques, Dora; Chavez-Galarza, Julio; Kryger, Per; Garnery, Lionel; Zee, Romée van der; Dahle, Bjørn; Soland-Reckeweg, GabrieleThe 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...
Introgression of lineage c honey bees into black honey bee populations: a genom...
Henriques, Dora; Chavez-Galarza, Julio; Kryger, Per; Johnston, J. Spencer; De la Rúa, Pilar; Rufino, José; Dall'Olio, Raffaele; Garnery, LionelThe black honey bee, Apis mellifera mellifera L., is probably the honey bee subspecies more threatened by introgression from foreign subspecies, specially lineage C A. m. carnica and A. m. ligustica. In fact, in some areas of its distributional range, intensive beekeeping with foreign subspecies has driven A. m. mellifera populations to nearly replacement. While massive and repeated introductions may lead to lo...

Effect of linkage disequilibrium on inferences of population structure and intr...
Chavez-Galarza, Julio; Henriques, Dora; Kryger, Per; De la Rúa, Pilar; Johnston, J. Spencer; Rufino, José; Pinto, M. AliceIdentification of population structure, a primary goal in population genetics, is easily performed because there is a number of methods available, implemented by user-friendly software packages. However, the user must be cautious when inferring population structure because spurious results may be obtained when there is strong linkage disequilibrium. With recent development of high-density SNPs we have now more ...
A review of methods for discrimination of honey bee populations as applied to E...
Bouga, Maria; Alaux, Cedric; Bienkowska, Malgorzata; Büchler, Ralph; Carreck, Norman; Cauia, Eliza; Chlebo, Robert; Dahle, Bjorn; Dall'Olio, RaffaeleHere, scientists from 19 European countries, most of them collaborating in Working Group 4: “Diversity and Vitality” of COST Action FA 0803 “Prevention of honey bee COlony LOSSes” (COLOSS), review the methodology applied in each country for discriminating between honey bee populations. Morphometric analyses (classical and geometric) and different molecular markers have been applied. Even if the approach has bee...
Queen rearing and selection practices and their impact on the genetic diversity...
Bouga, Maria; Arnold, Gerard; Bienkowska, Malgorzata; Büchler, Ralph; Garnery, Lionel; Ivanova, Evgeniya; De Jong, David; De la Rúa, Pilar; Kence, MeralThe Apimondia working group on honey bee diversity and fitness (AWG 7) was created on October 25, 2010 as a Scientific Working Group of Apimondia. The aim of this AWG is to collect information on honey bee queen rearing practices, and examine their impact on the genetic variability and general health of honey bee colonies. The AWG consists of 23 members from 16 different countries. The world wide survey being c...
