Descriptive biogeography of Tomicus (Coleoptera: Scolytidae) species in Spain
TLDR
The potential distribution centres and potential distribution limits of Tomicus species in Iberia are modeled and the effectiveness of different models are assessed by comparing predicted results with observed data.
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.
Conservation Genetics of Cicindela Deserticoloides, an Endangered Tiger Beetle Endemic to Southeastern Spain
TLDR
DNA sequencing of some 1896 base pairs of mitochondrial DNA for one specimen each from three populations revealed only a single base pair change confined to a single of the three specimens, thus indicating an extremely low level of differentiation when compared to similar populations of Cicindela (s.l.) elsewhere.
Mitochondrial DNA variability in the Canary Islands honeybees (Apis mellifera L.)
TLDR
The mitochondrial DNA of individuals from 79 colonies of Apis mellifera from five Canary Islands was studied using the DraI test based on the restriction of PCR products of the tRNAleu–COII intergenic region and the haplotypes A14 and A15 are described for the first time.
The origin of multiple sex chromosomes in tiger beetles.
TLDR
The evolutionary origin of multiple sex chromosomes in Cicindelidae is analyzed by establishing the distribution of the multiple systems in major taxonomic groups in the context of a phylogenetic tree derived from 18S rRNA gene sequences.
Cytogenetic analysis of Australian tiger beetles (Coleoptera: Cicindelidae): chromosome number, sex‐determining system and localization of rDNA genes
TLDR
Silver staining of male meiotic nuclei reveals the presence of active nucleolar organizing regions (NORs) in the sex vesicle of the three species of Cicindela, and hybridization in mitosis and first metaphase stages indicate that rDNA genes are in three, medium- to small-sized, autosomal pairs.
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.
The internal transcribed spacers (ITS1 and ITS2) of the rDNA differentiates the bark beetle forest pests Tomicus destruens and T. piniperda
TLDR
Data suggest the validity of T. destruens as a phylogenetically differentiated entity from T. piniperda and the phylogenetic analysis of a 789 bp fragment of the 3′ end of the cytochrome oxidase I gene agrees with the two groupings obtained with the ITS2, showing a phylogenetic clustering rather than a phylogeographic structure.
Genetic structure and distinctness of Apis mellifera L. populations from the Canary Islands
TLDR
Phylogenetic analyses indicate that the Canarian honeybees are differentiated from other lineages and provide genetic evidence of their African origin.
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.
