A Comprehensive Phylogeny of Beetles Reveals the Evolutionary Origins of a Superradiation
The phylogeny of Coleoptera found that the success of beetles is explained neither by exceptional net diversification rates nor by a predominant role of herbivory and the Cretaceous rise of angiosperms, suggesting that beetle species richness is due to high survival of lineages and sustained diversification in a variety of niches.

Effect of land disturbance and stress on species traits of ground beetle assemblages
It is concluded that the ground beetle assemblages of the studied sites respond in a similar way to the same underlying environmental factors, which allows the precise definition of functional groups, which can be used to characterize functional diversity and its relationships with changes in land management.

Nucleotide substitution rates for the full set of mitochondrial protein-coding genes in Coleoptera.
The results suggest that cox1 might not be an optimal gene for implementing molecular clocks in deep phylogenies for beetles because it shows relatively slow rates at first and second codon positions but very fast rates at third ones, while nad5, nad4 and nad2 perform better, as they exhibit more homogeneous rates amongcodon positions.

The Effect of Geographical Scale of Sampling on DNA Barcoding
A CO1 data set of aquatic predaceous diving beetles of the tribe Agabini is presented and it is shown that even if samples are collected to maximize the geographical coverage, up to 70 individuals are required to sample 95% of intraspecific variation, showing that the geographical scale of sampling has a critical impact on the global application of DNA barcoding.

Ancient origin of a Western Mediterranean radiation of subterranean beetles
The results suggest that by the Early-Mid Oligocene the main lineages of Western Mediterranean Leptodirini had developed all modifications to the subterranean life and were already present in the main geographical areas in which they are found today. Expand
Biogeography and conservation of Iberian water beetles
An analysis is made of the main biogeographical trends and the conservation status of the aquatic Coleoptera from the Iberian peninsula, suggesting the exclusion of three species previously considered to be endangered or vulnerable, and the inclusion of two new species as vulnerable. Expand
Phylogeny of hydradephagan water beetles inferred from 18S rRNA sequences.
Full-length 18S rRNA sequence for 84 species of Hydradephaga is presented, including representatives of most major groups down to the tribal level, and a total of 68 species of the largest family, Dytiscidae, indicating a single colonization of the aquatic medium. Expand
Biogeographical links between steppe insects in the Monegros region (Aragón, NE Spain), the eastern Mediterranean, and central Asia
Sixty-two species of insects in thirty-six families and nine orders, plus one species of Acari, were found to have disjunct distributions, or to belong to species groups with disjunct distributions,Expand
Speciation of Iberian diving beetles in Pleistocene refugia (Coleoptera, Dytiscidae)
For some taxa Iberian populations were isolated during the Pleistocene long enough to speciate, and apparently did not expand their ranges to recolonize areas north of the Pyrenees, in contradiction to observations from fossil beetles in areas further north. Expand
