An increase in grassland rodent pests China has seriously affected ecological environments and the development of husbandry. Here, we used remote sensing data a species–environmental matching model to predict potential spatial distribution five major pest species (Microtus, Citellus, Myospalax, Meriones, Ochotona) northern China, examined how predicted suitability area depends on environmental ...

Russian ( Acipenser gueldenstaedtii), Persian ( A. persicus) and Siberian ( A. baerii) sturgeons are closely related 'Ponto-Caspian' species. Investigation of their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, 'baerii-like' mitotypes were found in the Caspian Sea among 35% of Russian stu...

The present study reports on three species of terrestrial isopods from western Iran. The genus Mongoloniscus Verhoeff, 1930 is recorded for the first time from Iran, with description of a new species: M. persicus sp. n. Protracheoniscus ehsani sp. n. is described and P. darevskii Borutzky, 1975 is redescribed based on Iranian specimens. The diagnostic characters of these species are figured and...

There are many efforts for identification of natural compounds from dietary or medicinal plants. Young roots and aerial parts of A. persicus have been used as food additive or salad vegetable in some parts of Iran. In this study, different fractions of the root extract of A. persicus were subjected for isolation and purification of secondary metabolites. The methanol extract of the roots was fr...

In this study, there is a description of a new species, Protzia longiacetabulata n.sp., and P. squamosa Walter, 1908 representing a new Protzia record for the fauna of Turkey. Protzia longiacetabulata n.sp. is closest to the P. halberti from the P. rotunda species group and identified from these species by the number of the leg claws and acetabuli. Furthermore, there is the first description of...
