Rodents of the family Octodontidae, endemic to South America, represent a group with low taxonomic richness (six genera and 14 species) but have great ecomorphological diversity epigean, semi-fossorial, fossorial, subterranean forms. We analyzed morphometric variation in humerus ulna, possible relationship substrate preference use, presence phylogenetic signal forelimbs traits (five biomechanic...

We sampled beetles by pitfall traps at two sites of its area: Visimskiy Reserve ((580N 610E, Kirovgrad province, Russia, the western border area) and Kemerovo city (540N 810E, centre area). At first site birch meadows plots were under study, second ? lawns in residential industrial zones dump 25 km from city. 2109 specimen measured for six linear traits. Elytra parameters similar both regions s...

This study examines the evolution hindwing shape in Chinese dung beetle species using morphometric and phylogenetic analyses. Previous studies have analyzed the evolution of wing shape within a single or very few species, or by comparing only a few wing traits. No study has analyzed wing shape evolution of a large number of species, or quantitatively compared morphological variation of wings wi...
