MtOrt: an empirical mitochondrial amino acid substitution model for evolutionary studies of Orthoptera insects [PDF]

open access: goldBMC Evolutionary Biology, 2020
Background Amino acid substitution models play an important role in inferring phylogenies from proteins. Although different amino acid substitution models have been proposed, only a few were estimated from mitochondrial protein sequences for specific ...

Fauna and landscape-zonal distribution of Orthoptera in the Komi Republic (Russia) [PDF]

open access: yesКавказский энтомологический бюллетень, 2020
Orthoptera is a promising model group of insects for large-scale zoogeographic studies. The Komi Republic (Russia, West Siberia) is a suitable region for such kind of work, because it has meridional orientation, coinciding with the global trend of ...

The response of Orthoptera to grazing on flood defense embankments in Europe [PDF]

open access: yesJournal of Orthoptera Research, 2018
European flood defense embankments form an excellent habitat for Orthoptera. To be effective against storms, these vegetated earth embankments have to be managed by grazing or mowing.

The effects of boric acid and citric acid on chiasma frequency and meiotic division in Chorthippus loratus (Acrididae:Orthoptera) males

open access: yesCumhuriyet Science Journal, 2020
In this study, the cytogenetic effects of boric acid and citric acid in meiosis were investigated. Chorthippus loratus species of grasshoppers were treated with boric acid and citric acid sprayed grass at doses of 250, 500 and 1000 µg/ml for 24 hours. As
