Abstract
The genus Zoegea L. belongs to Asteraceae family and has about 10 species in the world. This genus is considered to be an Irano-Turanian and Mediterranean element and is distributed in south-western and central Asia and in the central, southern, north-western and south-western parts of Iran as well. The subspecies classification of the genus is not consensus and various classifications could be found in different taxonomy resources. In this study various specimens from different regions of Iran were studied. In addition, anatomical and palynological characters were used to perform a cluster analysis in order to determine species groups. In the end, our results confirmed that Z. baldschuanica and Z. glabricaulis were distinct species.

Abstract
Parkinson is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. Pain and emotional disorders due to Parkinson negatively affect the quality of the patient’s life. Biarum carduchrum is an antioxidant plant with some application in traditional medicine. The aim of this study is to evaluate the protective effects of Biarum carduchrum extract on pain and emotional disorders caused by 6-hydroxydopamine injection. Rats were randomly divided into 5 groups of 8 animals. The control group received normal saline. Parkinson's groups were subjected to the injection of 6- OHDA in the right anterior mid-brain (MFB). In third, fourth and fifth groups, rats received Biarum carduchrum extract at doses of 100, 200 and 400 mg/kg via gavage 7 days after induction of Parkinson for 14 days. On day 15th, behavioral tests including forced swimming test and tail flick were performed. Treatment of Parkinsonian rats with Biarum carduchrum extract at doses of 100, 200 and 400 mg dramatically reduced the duration of immobility time in the forced swimming test. Rats treated by Biarum carduchrum extract at doses of 100, 200 and 400 mg showed significantly increased resistance to pain compared with Parkinsonian rats. The results of this study show that the Biarum carduchrum extract improves depression and pain induced by Parkinson, which is probably related to its antioxidant effects.

Abstract
The distribution patterns of taxa belonging to the section Hypoglottidei DC. were investigated using DIVA-GIS software. Based on Zohary classification, five global patterns, with the exception of widely distributed species, include 1. Centro-Asiatic province, 2. Irano-Anatolian province, 3. Pontic province, 4. East Mediterranean subregion and 5. West Mediterranean subregion, were identified. In addition, the Iranian species of this section were classified in three patterns: 1. Central Zagros 2. Khorasan-Kopet Dagh 3. Central and Eastern Alborz. The maps and distribution patterns of the species were also presented.

Abstract
Centaurea glastifolia, a plant species from the Asteraceae family, is distributed in the Northwest of Iran. This study carried out to determine suitable habitats and habitat connectivity of Centaurea glastifolia in three Provinces of West Azarbayejan, East Azarbayejan and Ardabil. Seven habitat variables and 36 presence points were selected for habitat modelling using six habitat distribution models of GLM, GAM, MARS, MaxEnt, RF and GBM. The ensemble map resulting from these models was used for habitat connectivity modelling using electrical-circuit method. Results of habitat evaluation revealed that suitable habitats of the species studied were mainly located in West Azarbayejan and east of Ardabil Provinces, for which distance from agricultural lands, mean annual temperature and distance from rangelands had the highest contribution to the model. Habitat connectivity modelling showed that the current density movement was highest in West Azarbayejan. Current density movement between East and Southeast of Ardabil was evaluated to be significant, whereas the current density movement between West Azarbayejan and Ardabil Provinces was relatively low. The high current density movement in West Azarbayejan indicates the species’ high dispersal ability in expanding its range across the area. The results of the current study could facilitate understanding of the distribution and dispersal of Centaurea glastifolia.
