Sampling of Euglenophyta was done in four stations from August 2005 through June 2006. Ecological factors such as pH, EC, salinity, temperature and various nutrients were measured. A total of 4 genus and 9 species were identified in this lake. Euglena proxima Dang., Phacus caudatus var. ovalis Drez. and Trachelomonas robusta Swir., showed high density 1420, 952, 2380 cell/cm3, respectively. In this lake density of Euglenophyta increased in warm seasons because of high ions such as nitrate and phosphate. Based upon algal flora results, Zayandeh Rood dam lake could be regarded as an oligo-mesotrophic lake.https://tbj.ui.ac.ir/article_17373_f63404072953088175aa3590b1423272.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90012320100622Variation in leaf morphology of Tilia spp. of in Hyrcanian forestsتنوع ریختی برگ نمدار (Tilia spp.) در جنگلهای هیرکانی112417374ENHamedYosefzadehDepartment of Forestry, Faculty of Natural Resources and Marine Sciences, Tarbiat Modares University, Noor, IranMasoudTabariDepartment of Forestry, Faculty of Natural Resources and Marine Sciences, Tarbiat Modares University, Noor, IranAbasaltHosseinzadeh ColagarDepartment of Biology, Faculty of Basic Sciences, University of Mazandaran, Babolsar, IranMostafaAssadiResearch Institute of Forests and Rangelands of IranAliSattarianDepartment of Forestry, Agriculture and Natural Resources of Gonbad University, IranHabibZareAgriculture and Natural Resources Research Center of Mazandaran, IranJournal Article20160614This research was carried out in order to investigate the presence of different species from the genus Tilia,. Phenetic analysis confirmed the presence of seven groups of leaves with distinguishable character from Tilia in Hyrcanian forests. Distinctive analysis presented the size of serrate, the presence of trichome on the leaf upper and lower surfaces and on the petiole as important discriminating traits. The fourth group was separated from other groups due to the presence of trichome on the two sides of leaves, dull green color and leathery leaves. Size of serrate, long acuminate tip were diagnostic traits of second and third groups, but lower surface and petiole of leaves of second groups had settelate trichomes. In the fourth and fifth groups, lower surface of leaves had settlate trichomes with short aristate and short acuminate, but the petiole of forth group had settlate trichome. In the sixth group, only petiole had trichome, while the leaf surface and petiole of seventh group was glabrate. In conclusion, this research, in addition to confirming the presence of of Tilia platyphyllos doubted the presence of Tilia begonifolia Steven, Tilia caucasica Rupr. and Tilia dasystyla Steven in the north of Iran. Also, it reported a new form of the genus Tilia in mountainous regions of Hyrcanian forests. However, definite decision regarding this case depends on complementary studies including investigating fruits and flower morphology with application of molecular techniques. https://tbj.ui.ac.ir/article_17374_c1d98158e2d07d358deedfd94554c3be.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90012320100622Taxonomic study of Onobrychis transcaspica V.

These species are used as valuable forage plants. Onobrychis sect. Onobrychis with nearly 15 species in Iran is one of the important sections of the genus. Onobrychis transcaspica V. Nikitin, is one of the species of this section that is distributed in NE of Iran. To determine intraspecific variations in O. transcaspica from taxonomic point of view and effective ecological factor, data were collected using special station method. In this way, four special stations were recognized for O. transcaspica in NE of Iran. Results from floristic data (Floristic composition of each special station) analysis with MVSP software by PCO method, led to identification of 3 separate groups that was indicative of existence of intraspecific diversity. Morphometric data analysis of individual collected from each special station, by using 65 vegetative and reproductive characters, with PCO and UPGMA methods, confirmed 3 mentioned floristic groups. Ecologic data analysis with CCA Method showed the presence of 3 phenoecodeme based on 3 morphologic groups resulting from altitudinal variations.https://tbj.ui.ac.ir/article_17375_6dd9bec29124a541d7f480021780bff2.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90012320100622Potentilla radiata Lehm. and Potentilla balansae Sojak. two new record species for the Flora of Iranدو گزارش جدید از خانواده گل سرخ برای فلور ایران Potentilla radiata Lehm. و Potentilla balansae Soják394617376ENMarzieh BeygomFaghirCentral Herbarium of Tehran University, School of Biology, University College of Science Tehran, IranFaridehAttarCentral Herbarium of Tehran University, School of Biology, University College of Science Tehran, IranJiriSojakDepartment of Botany, The National Museum in Prague,Czech RepublicJournal Article20160614For the first time, Potentilla balansae Sojak. and Potentilla radiata Lehm. are reported from north and northeast of Iran.

The specimen was collected during a field investigation in Kurdistan in 2008. Illustrated descriptions of the species together with a short note on the species as well as its distribution in Iran are provided. Micro-morphological studies on pollen grains and also fruit surface were performed. Pollen grains were heteropolar and 3panto colporate with more or less psilate surface. Mericarp surface had white glands on a wrinkled substrate which is the most important diagnostic feature in species recognition.https://tbj.ui.ac.ir/article_17377_d045a084bbc8c6717c4fa5838a8e436e.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90012320100622Microsatellite polymorphism in natural populations of threatened Caspian roach in Golestan coastsچند شکلی ریزماهوارهای در جمعیتهای طبیعی گونه در معرض تهدید ماهی کلمه خزر در سواحل استان گلستان556617378ENHadisehKashiriFisheries Faculty, Gorgan University of Agriculture Sciences and Natural Resources, IranAliShabaniFisheries Faculty, Gorgan University of Agriculture Sciences and Natural Resources, IranBaharehShabanpourFisheries Faculty, Gorgan University of Agriculture Sciences and Natural Resources, IranMohammadRezaiiFisheries Faculty, Gorgan University of Agriculture Sciences and Natural Resources, IranJournal Article20160614To investigate the population structure of Caspian roach, one of the economically important and threatened species of Caspian Sea, 58 samples were collected from Gorgan river and Gorgan bay and then they were studied using 10 microsatellite loci. All of the 10 loci were polymorphic and showed polymorphism information content from 0.72 to 0.93. Results indicated that allelic (allele number: 10.3) and gene (heterozygosity: 0.67) diversity of the regions are at an acceptable level. 10 cases of 20 investigated tests (10 loci × 2 populations) showed significant deviation from Hardy-Weinberg equilibrium, mainly due to the heterozygosity deficiency. UPGMA cluster analysis, based on Nei genetic distance, didn’t show distinct departure among populations. Also, analysis of molecular variance showed high diversity (98%) within the populations.https://tbj.ui.ac.ir/article_17378_7bd9f257c160bb5b64096f4e0b6c9bc3.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90012320100622Comparison of two subspecies of Barbus capito in southern parts of Caspian Sea basinمقایسه زیستسنجی دو زیر گونه اسمی Barbus capito capito و Barbus capito conocephalus در حوزه جنوبی دریای خزر677717379ENJalalValiallahiDepartment of Environment, Shahied Rajaee Teacher Training University, Lavizan, Tehran, IranJournal Article20160614As for <em>Barbus capito</em>, two subspecies have been reported by L. S. Berg (1949) and other authors. To distinguish these two forms, 35 specimens were examined according to the main reported differences. All of these specimens have been collected in southern parts of Caspian Sea and are part of CMN (Canadian Museum of Nature) fish collection mainly collected by B. W. Coad. To analyze patterns of morphological variation in these specimens, PCA and DFA were used. The main differences were in head length, dorsal body length, caudal length and barbells length. There were no distinguishable characters for separating these two forms into two species. Considering other differences, the head length was not stable and could not be regarded as a distinctive character. However, in south of Caspian Sea, in addition to typical <em>B. capito</em> there were variations within this species with bigger head, longer caudal fork and longer pectoral.https://tbj.ui.ac.ir/article_17379_4e3a514303136eb2f0c16665088e9153.pdf
