“…The need to conserve genetic diversity in wild bee populations and understanding its structure and function to design successful breeding and conservation programs has been highlighted recently (López-Uribe, Soro & Jha, 2017). Because of several potential causes, populations of both managed and wild bees have been reported to be declining during the last decade in different parts of the world (Biesmeijer et al 2006).…”

La península Ibérica alberga una gran diversidad de abejorros, pero falta mucha información sobre su biodiversidad en esta zona. Para evitar esto y facilitar estudios de conservación, presentamos dos novedosos ensayos para la amplificación múltiple de seis y cinco loci de microsatélites respectivamente. Ambos ensayos funcionaron con éxito para la mayoría de las especies estudiadas en las poblaciones ibéricas. Se detectaron las obreras hermanas y se infirieron parámetros genético-poblacionales en la especie manejada B. terrestris y en las especies silvestres B. monticola y B. mesomelas, demostrando la capacidad de estos ensayos para estudios de biodiversidad de especies de abejorros tanto manejadas como silvestres.

“…A endogamia reduz a heterozigosidade com o passar das gerações . A alta diversidade genética em abelhas é importante porque influencia na saúde, resistência a patógenos e no fitness das colônias comerciais de Apis sp (López-Uribe et al 2017;Mattila & Seeley 2007;Oldroyd & Fewell 2007;Page 1980;Seeley & Tarpy 2007).…”

“…Investigações forenses da origem de animais e plantas traficados também necessitam de unidades de gerenciamento delimitadas para ações de investigação e intervenção (Alacs et al 2010;Nazareno & dos Reis 2014;. A identificação de unidades de manejo também é central para o monitoramento de frequências alélicas e a distribuição da diversidade genética neutra e adaptativa, gerando dados que podem ser usados em programas de cruzamento, tanto em populações livres quanto em cativeiro López-Uribe, Soro & Jha, 2017b). Em cativeiro, o uso de poucos fundadores ou protocolos errôneos de reprodução pode causar perda da variabilidade genética, comprometendo os esforços de recuperação da espécie e tornando o gerenciamento genético de extrema importância para conservação da biodiversidade de espécies comerciais (Féral, 2002;Schwartz, Luikart, & Waples, 2007).…”

Efeitos da meliponicultura na diversidade genética de Melipona quadrifasciata 1836 (Apidae, Meliponini) na região sul do Brasil

Social stingless bees have been manipulated by man since the pre-European civilization era; management practices include artificial colony division/multiplication and nest transport. We evaluated the effects of common management practices on the genetic diversity of Melipona quadrifasciata within its native range in southern Brazil. The proposed research hypotheses are: 1) Genetic diversity in meliponaries reflects natural variation and population genetic structuring; 2) Migrant nests can be identified; 3) Meliponaries in which colonies are artificially divided suffer from inbreeding. We employed microsatellite and mitochondrial DNA markers to test these hypotheses. The genetic diversity in our sample was compatible with that of feral populations investigated by other researchers, although this diversity was heterogeneously distributed. We observed that meliponaries subjected to intensive colony multiplication exhibited signs of inbreeding. We also found haplotypes of various origins in meliponaries into which colonies had been introduced, which affected local diversity and resulted in the homogenization of allele frequencies in various regions. Although no genetic structuring was observed, a clinal genetic differentiation was found based on microsatellite markers. The mtDNA analyses showed geographic displacement of the queens, in addition to the introduction of haplotypes from the southeastern region of the country. Population differentiation and isolation by distance could not be used to effectively delimit management units based on natural gene flow. We suggest that efforts to preserve genetic diversity should focus on regulating management practices, allowing gene flow only via natural vegetation fragments, and that diversity management should focus on local regions, reflecting geographic and sociopolitical scenarios already utilized in other environmentally oriented natural population management plans.

Population genomics and phylogeography of Colletes gigas, a wild bee specialized on winter flowering plants

Diet specialization may affect the population genetic structure of pollinators by reducing gene flow and driving genetic differentiation, especially in pollen‐specialist bees. Colletes gigas is a pollen‐specialist pollinator of Camellia oleifera , one of the most important staple oil crops in China. Ca . oleifera blooms in cold climates and contains special compounds that make it an unusable pollen source to other pollinators. Thus, C . gigas undoubtedly plays a key role as the main pollinator of Ca . oleifera , with biological and economic significance. Here, we use a population genomic approach to analyze the roles of geography and climate on the genetic structure, genetic diversity, and demographic history of C . gigas . A total of 1,035,407 SNPs were identified from a 582.77 Gb dataset. Clustering and phylogenetic analyses revealed a marked genetic structure, with individuals grouped into nine local clusters. A significant isolation by distance was detected by both the Mantel test ( R = .866, p = .008) and linear regression ( R 2 = .616, p < .001). Precipitation and sunshine duration were positively and significantly ( R ≥ .765, p ≤ .016) correlated with observed heterozygosity ( H o ) and expected heterozygosity ( H e ). These results showed that C . gigas populations had a distinct phylogeographic pattern determined by geographical distance and environmental factors (precipitation and sunshine duration). In addition, an analysis of paleogeographic dynamics indicated that C . gigas populations exhibited patterns of glacial expansion and interglacial contraction, likely resulting from post‐glacial habitat contraction and fragmentation. Our results indicated that the peculiar phylogeographic patterns in C . gigas populations may be related to their specialization under long‐term adaptation to host plants. This work improves our understanding of the population genetics in pollen‐specialist bees. The distinct genetic clusters identified in this study should be taken into consideration for the protection and utilization of this specialized crop pollinator.
