“…Given their natural isolation this should theoretically be an easy task, and will basically depend on the ability of beekeeping policies to restrict the introduction of foreign honeybees (De la Rúa et al, 2001b, 2003Bouga et al, 2005b).…”

“…Native honeybee populations inhabiting Mediterranean Islands have similarly suffered introgression from foreign honeybee subspecies. Among the Balearic Islands (Spain), only Mallorca seems to harbour a relatively well preserved honeybee population, whereas Formentera, Ibiza and Menorca show evidence of recent introgression events that have substantially changed the genetic pool of the ancestral local populations (De la Rúa et al, 2001b, 2003. Moreover, most native honeybees from Fomentera are likely to have disappeared due to a combination of the effects of diseases and low population size.…”

-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

“…La heterocigosidad media esperada (H e ) de la población insular de M. beecheii (0,411) es algo menor que la obtenida en las poblaciones continentales de M. beecheii estudiadas por QuezadaEuán et al (2007) de México (0,535) y Costa Rica (0,711). Esto es debido, probablemente, al hecho de que las poblaciones estudiadas en este trabajo son insulares y éstas suelen presentar valores más bajos de heterocigosidad tal y como se ha observado en poblaciones insulares de la abeja de la miel A. mellifera (De la Rúa et al, 2001).…”

RESUMENEn este estudio, se ha analizado por primera vez la variabilidad de los loci de microsatélites en la especie silvestre de abejas sin aguijón Melipona colimana. Los datos obtenidos se han comparado con los de una población insular de la especie domesticada M. beecheii. Los resultados del genotipado de los individuos de M. colimana, indican que la secuencia de los loci de microsatélites está conservada dentro del género Melipona. Los parámetros poblacionales estudiados (número de alelos y valores de heterocigosidad) no mostraron diferencias significativas entre las dos especies estudiadas, estando ambos dentro del rango observado en otras especies del género. Estos valores fueron inferiores en la población insular de M. beecheii con respecto a otras poblaciones continentales de la misma especie analizadas previamente, lo cual coincide con lo observado en estudios previos de otros organismos insulares. La especie silvestre M. colimana es susceptible a los efectos de la deforestación, por ello se han comparado parámetros poblacionales de colmenas situadas en una zona deforestada y en otra conservada. La diversidad poblacional no ha mostrado diferencias significativas, probablemente debido a que las perturbaciones del medio estudiado son recientes y aún no se han reflejado en la diversidad genética de estos insectos. SUMMARYIn this study, variability of microsatellite loci has been for the first time analyzed in the wild stingless bee Melipona colimana. Data have been compared with those obtained from an insular population of the managed species M. beecheii. Genotyping results in M. colimana demonstrate that microsatellite loci sequences are conserved within the genus Melipona. Population parameters such as number of alleles and heterocigosity values, were not significantly different between the two studied species, both being within the observed range in other Melipona species. Values of the insular M. beecheii population were lower than in previously studied continental populations of the same species, in agreement with the results obtained in other island organisms. Wild M. colimana colonies are susceptible to deforestation effects, so that, we have compared the genetic parameters of colonies from a deforested area with those of a conserved area. Population diversity was not significantly different, may be due to recent environmental perturbations that are not yet reflected in the genetic diversity of these insects.

“…Nevertheless, anthropogenic factors may rapidly change this pattern because of the great development of mobile beekeeping and man-made replacement of native colonies (Cánovas et al 2008), as it was found on the islands of Formentera and Ibiza (De la Rúa et al 2001) and on the Canary Islands (De la Rúa et al 2002a). It should be noted that the geographic distribution of microsatellite markers in Iberian populations has been possibly changed by apiculture practices during the last 20 years.…”

Microsatellite variability reveals beekeeping influences on Iberian honeybee populations

-The genetic structure of the Iberian honey bee (Apis mellifera iberiensis) was studied by analysing 10 microsatellite loci in 362 workers representative of nine Spanish provinces. Heterozygosity values of Iberian honeybee populations are intermediate between African and west European ones whereas allelic diversity is remarkably high at several loci. There is no definite geographic structure of Iberian honeybee populations. At a peninsular scale, the expected clinal pattern observed with mitochondrial data has been probably lost due to the extensive practice of mobile beekeeping and increased colony trade-off. Due to these practices, it is expected that the genetic homogenisation will increase during the next years. Though this might have positive effects on honey production, putative ecotypes existing in Iberia would be prone to disappear.Apis mellifera / population genetics / synthesis maps
