Large Scale Mitochondrial Evidence of C-lineage Dominance in European Honey Bees
Li, Fernanda; Lopes, Ana; Costa, Maíra; Henriques, Dora; Quaresma, Andreia; Yadró García, Carlos A.; Albo, Alexandre; Čereškienė, Laima BlažytėIn Europe, distribution of the several endemic honey bee (Apis mellifera) subspecies has suffered a considerable shift in the last century. In particular, beekeepers tend to favour subspecies of Eastern European ancestry (C-lineage), such as the Italian honey bee (A. m. ligustica), due to their perceived docility and high honey production. As a result, large scale migratory beekeeping and trade of C-lineage que...
Exploiting the mitogenomes of apis mellifera subspecies to develop an authentic...
Honrado, Mónica; Henriques, Dora; Santos, Joana; Yadró Garcia, Carlos A.; Martín-Hernández, Raquel; Nanetti, Antonio; González, Amelia VirginiaHoney 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...
Maternal origin of honeybee (Apis mellifera) colonies from across Europe
Lopes, Ana; Costa, Maíra; Tounakti, Sahar; Henriques, Dora; Quaresma, Andreia; Yadró Garcia, Carlos A.; Albo, Alexandre; Blažytė-Čereškienė, LaimaWorldwide commercial beekeeping poses a threat to the native origin of the honeybee (Apis mellifera), with beekeepers favouring subspecies of Eastern European C-lineage ancestry, due to their docile behaviour and high honey production traits. In many parts of western and northern Europe, queens of Western European M-lineage ancestry have been massively replaced by queens of C-lineage ancestry, and this has led ...
Semi-automated sequence curation for reliable reference datasets in ITS2 vascul...
Quaresma, Andreia; Ankenbrand, Markus J.; Garcia, Carlos Ariel Yadró; Rufino, José; Honrado, Mónica; Amaral, Joana S.; Brodschneider, RobertOne of the most critical steps for accurate taxonomic identification in DNA (meta)-barcoding is to have an accurate DNA reference sequence dataset for the marker of choice. Therefore, developing such a dataset has been a long-term ambition, especially in the Viridiplantae kingdom. Typically, reference datasets are constructed with sequences downloaded from general public databases, which can carry taxonomic and...
An unprecedented large-scale survey of honey bee mitochondrial diversity in Eur...
Li, Fernanda; Costa, Maíra; Lopes, Ana Rita; Gonçalves, Telma; Henriques, Dora; Quaresma, Andreia; Yadró Garcia, Carlos A.; Albo, AlexandreEurope is home to ten Apis mellifera subspecies, which belong to three mitochondrial lineages: the Western European (M), Eastern European (C), and African (A). However, the long-standing human-mediated movement of queens, primarily of C-lineage ancestry, has threatened the genetic integrity of many of these native subspecies through introgression and replacement. This has led to the establishment of conservatio...
Wing geometric morphometrics of european honey bee populations
Costa, Maíra; Gonçalves, Telma; Lopes, Ana; Vitrio, Nathalia; Albo, Alexandre; Blažytė-Čereškienė, Laima; Brodschneider, Robert; Brusbardis, ValtersWing venation patterns have long been used to identify honey bee subspecies, singly or in combination with other morphological traits, using different approaches. Beekeepers have traditionally used identification methods that only require estimations of the Cubital Index, Hantel Index, and/or Discoidal Shift Angle. However, these measures do not consider all the information carried by wing patterns, and a more ...
Honey bee (Apis mellifera) wing images: a tool for identification and conservation
Oleksa, Andrzej; Cauia, Eliza; Siceanu, Adrian; Puskadija, Zlatko; Kovačić, Marin; Pinto, M. Alice; Rodrigues, Pedro J.; Hatjina, FaniThe honey bee (Apis mellifera) is an ecologically and economically important species that provides pollination services to natural and agricultural systems. The biodiversity of the honey bee in parts of its native range is endangered by migratory beekeeping and commercial breeding. In consequence, some honey bee populations that are well adapted to the local environment are threatened with extinction. A crucial...
Bio-Monitoring of environmental pollution using the citizen science approach
Steen, Jozef van der; Amaral, Joana S.; Baveco, Hans; Blanco Muñoz, Patricia; Brodschneider, Robert; Brusbardis, Valters; Buddendorf, BasHoneybee colonies are excellent bio-samplers of biological material such as nectar, pollen, and plant pathogens, as well as non-biological material such as pesticides or airborne contamination. The INSIGNIA-EU project aims to design and test an innovative, non-invasive, scientifically proven citizen science environmental monitoring protocol for the detection of pesticides, microplastics, heavy metals, and air p...
Authoritative subspecies diagnosis tool for European honey bees based on ancest...
Momeni, Jamal; Parejo, Melanie; Nielsen, Rasmus O.; Langa, Jorge; Montes, Iratxe; Papoutsis, Laetitia; Farajzadeh, Leila; Bendixen, ChristianWith numerous endemic subspecies representing four of its five evolutionary lineages, Europe holds a large fraction of Apis mellifera genetic diversity. This diversity and the natural distribution range have been altered by anthropogenic factors. The conservation of this natural heritage relies on the availability of accurate tools for subspecies diagnosis. Based on pool-sequence data from 2145 worker bees repr...
Its2 metabarcoding: a promising approach for identification of botanical origin...
Quaresma, Andreia; Van der Steen, Joseph; Amaral, Joana S.; Biron, David G.; Brodschneider, Robert; Brusbardis, Valters; Carreck, Norman L.Bee products have long been used in human’s diet and their consumption has increasingly been recognized has beneficial for human’s health. One such product is pollen, which is a particularly interesting food as it contains bioactive compounds and all the essential amino-acids needed by humans. However, the composition of bee-collected pollen depends on the environment where the visited plants grow (e.g.: climat...
