Climate change has a great impact on the species distribution range and many endangered plant species. Fritillaria imperialis as a species that is native to Central Zagros, Iran is a medicinal plant with great ecological and commercial profits. Its population has decreased considerably and the species would be endangered in later decades. Understanding the habitat needs of this species, evaluat...

In this article the collection of specimens related to Onosma sulaimanica from Kordestan Province, Iran, was confirmed and reported for the first time. Therefore, the species is recorded for the flora of Iran. This species is placed in the sect. Onosma, subsect. Onosma, ser. Wheeler-hainesii. A diagnostic key of related taxa belonging to series Wheeler-Hainesii and Aleppica, and the photos, mic...

The distribution and abundance of high aquatic plants in the Gorganroud River was examined at five stations in four seasons (20 samples) over one year period during 2009-2010. We identified 21 species of aquatic plants from 21 genera, belonging to 9 families. These species were determined as 3 halophytic species (14.2%) and 18 high aquatic plants (85.7%).The highest species diversity was observ...

Modeling species distributions over space and time is one of the major research topics in both ecology conservation biology. Joint Species Distribution models (JSDMs) have recently been introduced as a tool to better model community data, by inferring residual covariance matrix between species, after accounting for species' response environment. However, these are computationally demanding, eve...

the genus exoprosopa macqurt, 1840 (diptera: bombyliidae: anthracinae) was studied in the north central iran. four species of the genus exoprosopa were identified of which e. minos (meigen,1804) and e. grandis (pallas, 1818) were previously recorded from northern parts of iran ( or north of iran ) and two species namely e. efflatounbeyi paramonov, 1928and e. altaica paramonov, 1925 are newly re...

The production and proper utilization of medicinal plants in natural habitats need to review and identify the natural conditions and climate of the habitat of these plants and separating them from harmful and poisonous plants. The current study was aimed to introduce and determine the distribution of medicinal plants from Lamiaceae family in Mazandaran province as well as the introduction of na...
