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.

M any natural landscapes have undergone dramatic permanent alterations as a result of human activities, including conversion to cultural landscapes; such changes are readily observed and understood. However, extensive ecological change can also occur in regional landscapes that are maintained in a seminatural state, changes that go largely unrecognized because the regional landscape retains an ...

Throughout the western United States, the invasive annual grass, medusahead (Taeniatherum caputmedusae L. Nevski), is rapidly invading grasslands once dominated by native perennial grasses, such as bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) A). It is also invading grasslands dominated by less undesirable invasive annual grasses, especially cheatgrass (Bromus tectorum L.). Understandi...

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...

We investigated the effects of chemical variation in thyme (Thymus vulgaris L.) on its interactions with competitors, herbivores, and herbivore predators. Four different thyme monoterpene phenotypes (chemotypes) were grown in a 4x2x2 factorial of chemotype, caging (sham half-cages vs. full cages), and competition (control vs. the grass Bromus madritensis L.). Cages reduced numbers of arthropod ...

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...
