Biodiversity, conservation and current threats to European honeybees
TLDR
The biodiversity of European honeybees is reviewed and the management and conservation strategies employed by different countries are summarized and a comprehensive picture of the beekeeping industry in Europe is provided.
Geographical patterns of mitochondrial DNA variation in Apis mellifera iberiensis (Hymenoptera: Apidae)
TLDR
It has been found that the Iberian Peninsula is the European region with the highest haplotype diversity (12 haplotypes detected of the M lineage and 10 of the A lineage) and the frequency of A haplotypes decreases in a SW-NE trend, while that of M haplotypes increases.
Molecular characterization and population structure of Apis mellifera from Madeira and the Azores
TLDR
On en a conclu that les abeilles des Canaries avaient probablement une origine africaine avec un certain degre de differenciation du a l'isolement par rapport aux populations continentales.
Maternal diversity patterns of Ibero-Atlantic populations reveal further complexity of Iberian honeybees
TLDR
A fine-scale maternal survey of the Portuguese honeybee populations revealed unparalleled levels of African maternal diversity and a remarkable north–south cline formed by African haplotypes of distinct ancestry.
New insights into the mitochondrial phylogeny of the whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) in the Mediterranean Basin
TLDR
Results indicated that Bemisia populations corresponding to the biotypes S and T are distributed in areas larger than those initially delimited, and samples collected in Sudan grouped within the Mediterranean–North Africa clade together with reference sequences of the biotype Q corresponding to insects collected in Spain and Morocco.
Climate rather than geography separates two European honeybee subspecies
TLDR
Honeybee subspecies differentiation strongly correlated with the various temperature zones in Romania means that Apis mellifera carnica is more abundant in regions with the mean average temperature below 9 °C, whereas A. m.
Conserving genetic diversity in the honeybee: Comments on Harpur et al. (2012)
TLDR
Concerns are expressed about the conclusions drawn from the results of Harpur et al. (2012), convinced that the large‐scale genetic homogenization of admixed populations could drive the loss of valuable local adaptations in honeybee colonies.
Localization and activity of rDNA genes in tiger beetles (Coleoptera: Cicindelinae)
TLDR
The nucleolus does not seem to play a major role in the pairing and association of the multiple sex chromosomes during first meiotic prophase and metaphase and changes of location of NORs from the heterosomes to the autosomes have occurred within species of this genus, at least in species showing extensive karyotypic repatterning.
Population genetic structure of coastal Croatian honeybees (Apis mellifera carnica)
TLDR
Through the Bayesian analysis of microsatellite variation, two groups can be distinguished within the Croatian honeybee population, suggesting the existence of two subpopulations of A. m.
Molecular characterization and population structure of the honeybees from the balearic islands (Spain)
TLDR
Phylogenetic and population structure analyses support the clustering of these islands in two groups: Majorca-Minorca (Gymnesic) and Ibiza-Formentera (Pityusic) what corroborates the current biogeographical division of the Balearic organisms.
