Modern methods allow a geometric representation of forms, separating size and shape. In
entomology, as well as in many other fields involving arthropod studies, shape variation has …

Trechini ground beetles include some of the most spectacular radiations of cave and
endogean Coleoptera, but the origin of the subterranean taxa and their typical …

Insect male genitalia show an evolutionarily variable morphology that is valuable for both
species identification and phylogenetic analyses. However, we often encounter some …

Members of the Maculatus group are important malaria vectors in the border regions of
Thailand. However, the role of each species in malaria transmission remains unclear …

Ground beetles in multiple species vary greatly in the expression of the shape on sexual
traits, resulting in a sexual shape dimorphism as a consequence of sexual selection …

The highly modified morphology and ecological features of cave-dwelling organisms are a
strong obstacle to dispersion. Hence, they represent ideal models for the study of historical …

Located in Northern Pyrenees, in the Arbas massif, France, the system of the Coume
Ouarnède, also known as Réseau Félix Trombe—Henne Morte, is the longest and the most …

The Pleistocene glaciations shaped the distribution and population structure of most
European species. Some species survived the glacial cycles by shifting their range to …

Ground beetles include many species of rather recent evolutionary origin that are extremely
similar in their external morphology. We used geometric morphometrics to quantify the …

Introducción. En años recientes se han encontrado P. geniculatus infectados con
Trypanosoma cruzi en ambientes rurales y urbanos de Caracas, Venezuela, lo que indica …
