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...

In this study, torrenticolid water mite specimens collected from Kulp district (Diyarbakır, Türkiye) between 2020-2021 years were evaluated. Totaly, 15 species are determined belonging to the family Torrenticolidae. Torrenticola (s.str.) laskai Di Sabatino, 2009, (Megapalpis) persica Pesic, 2004 and Monatractides persicus new records for fauna of Türkiye. The male has been described first time.

The objective of this study was to compare biological parameters such as length, weight, age, caviar production indices, caviar/weight, growth, condition factor and sex ratios of Persian sturgeon (Acipenser persicus Borodin, 1897) and Russian sturgeon (A. gueldenstaedti Brandt & Ratzeburg, 1833) in the Caspian Sea during 1990-2014. The results showed that a variety of differences between this t...

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...

Original meiotic or both and mitotic chromosome numbers are reported for ten endemic one non species in nine vascular plant families from Iran. The of Acantholimon schahrudicum, A. truncatum, Anthochlamys multinervis, Campanula perpusilla, Cousinia calcitrapa var. interrupta, Dorema ammoniacum, Euphorbia gedrosiaca, Hyocyamus orthocarpus were determined the first time. counts Astrodaucus persic...

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...

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...

so far, four species of hemidactylus have been reported in iran as follows: h. persicus, h. robustus, h. flaviviridis, h. romeshkanicus. in this study, 108 specimens belonging to these four species of hemidactylus were examined morphologically, using 19 metric and 6 meristic characters. multivariate analyses showed morphological differences among these three species with exception h. romeshkani...

Objective- Acipenser persicus is one of the most important caviar producing fishes in the Caspian Sea and one of the endangered species of the sturgeon fishes. For breeding of sturgeons, large numbers of animals have to be captured and examined to obtain sufficient numbers of mature fishes that will spawn within a few months in captivity. Design- Original study Animals- A total of 66 adult Acip...
