In the present study, two populations of <em>Acomys dimidiatus </em>from different locations of Hormozgan Province (Geno sanctuary and Minab County) were compared according to their morphometric, morphological and ecological characteristics. Fifty eight specimens of adult <em>A. dimidiatus</em> were collected by live traps (Sherman traps, Havahart traps and locally made traps) from these regions. We caught the rodents from the height ranging from <100 to >1500 meters. According to our field observations, the studied species was mostly nocturnal. At first, five external and fifteen cranial- dental characters were measured, then ratios of measured characters to head and body length were calculated. The normality of data was analyzed by Kolmogorov- Smironov test. Descriptive statistics were calculated for characters and ratios. The results showed that the average of 14 out of 20 characters in Minab specimens was greater than Geno specimens. Also, the average of all of the ratios (20 ratios) in Minab specimens was greater than that of Geno region. Independent Sample T-Test was used to test the statistical significance between length and ratios. The results indicated that there were significance differences in five out of twenty characters and nine out of twenty ratios in two regions(p<0.05). In addition, MANOVA test revealed significant differences among the studied populations (p<0.05). Also, intraspecific variations were assessed with the principal components analysis (PCA). The first two principal components accounted for more than 60% of the total variance and the species were fairly well separated by them.https://tbj.ui.ac.ir/article_17421_b79d52d05b3a24d64fddeac4f7264643.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90013920120220Introduction of the flora, life form and chorology of the Alla region and Rudzard in Khuzestan provinceمعرفی فلور، شکل زیستی و پراکنش جغرافیایی منطقه اعلاء و رودزرد استان خوزستان153017422ENShabnamTaghipourDepartment of Biology, Faculty of Sciences, University of Urmia, Urmia, IranMohammadHassanzadehResearch Center of Agriculture and Natural Resources, Khuzestan Province, Ahwaz, IranSiavashHosseini SargheinJournal Article20160614The studied watershed region of Alla and Rudzard rivers is located between Khuzestan (Baghmalek and Izeh) and Kohgiloye va Boyerahmad provinces with the area of 229903.4 hectares.

In this study, the flora, life form and geographical features of the protected area were investigated. In this area, a total of 393 species including 3 pteridophyta, 2 gymnosperma, 337 dicotyledons and 56 monocotyledons were identified. They belonged to 81 families and 268 genera. The following families had the highest number of species: Asteraceae, Papilonaceae, Poaceae, Brassicaceae, Apiaceae,and Boraginaceae. The following genera had the highest number of species: Astragalus, Juncus, Convolvulus, Anthemis and Plantago. 230 species (58.52%) were Irano-Turanian region. Therophytes with 215 species (54.70%) was the most frequent life form of the protected area.https://tbj.ui.ac.ir/article_17423_074f2485021816fadab95725172bad32.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90013920120220A cytotaxonomic study of Leucopoa Griseb.

This genus possesses two speices namely L. sclerophylla and L. pseudosclerophylla in Iran. A total of three accessions belonging to L. sclerophylla and L. pseudosclerophylla were examined in this investigation. So far, no chromosome number has been reported in this genus. The diploid numbers counted in this study were 2n=42 and x=7 for three populations belonging to two studied species. The karyotypic observations and chromosomal parameters showed more or less nonsymmetrical profiles in this genus.https://tbj.ui.ac.ir/article_17424_f37cceade0ace97a14ba0b89cad7e4ad.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90013920120220Meiotic chromosome number and behavior of six populations of Onobrychis melanotricha Boiss.

However, its main centers of diversity are eastern Mediterranean and southwestern Asia. O. sect. Heliobrychis is the largest section of the genus and has nearly 21 species in Iran. In this investigation, the chromosome number and meiotic behavior were studied in 6 populations of O. melanotricha. All taxa were diploid and had the basic chromosome number of 2n=2x=16. Although the taxa represented regular meiosis, some abnormalities such as laggard and fragmented chromosomes in anaphase/telophase I, II and diakinesis/methaphase I, cytomixis in anaphase/telophase I, II, micronucleus in telophase II, multipolar cells in telophase II, bridges in anaphase I and asynchronous nuclei in metaphase II and telophase I and II were observed.https://tbj.ui.ac.ir/article_17425_a559c276f25c6785ab4c2c319e476ed2.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90013920120220A cytotaxonomic study of Cynodon dactylon (L.)

The taxonomic and cytological status of this species is not well documented. In this study, the cytological characteristics of 10 samples collected from different regions of Iran were analysed. Two ploidy levels: tri and tetraploid were counted from the root tips as 2n=3x=27 and 2n=4x=36 with a basic chromosome number of x=9. The karyotypes and the chromosomal parameters showed a nearly symmetrical karyotypes. The presence of triploid populations indicated that the probable existence of the diploid populations in this region hybridized with tetraploid individuals in the past to produce triploids that subsequently stabilized by vegetative reproduction (rhizome).https://tbj.ui.ac.ir/article_17426_ab92458095d65bb8d740799ef610afa7.pdfUniversity of IsfahanTaxonomy and Biosystematics3115-90013920120220A survey on flora, life forms and geographical distribution of plant species in the protected forests of Fandoghlu (Ardabil province)معرفی فلور، اشکال زیستی و پراکنش جغرافیایی گونههای گیاهی منطقه جنگلی و حفاظتشده فندقلو (استان اردبیل)758817427ENFarzanehAzimi MotemResearch Center of Agriculture and Natural Resources, Ardabil province, Ardabil, IranRezaTalaiResearch Center of Agriculture and Natural Resources, Ardabil province, Ardabil, IranFatemehAsiabizadehResearch Center of Agriculture and Natural Resources, Ardabil province, Ardabil, IranMoharramHoushyarResearch Center of Agriculture and Natural Resources, Ardabil province, Ardabil, IranJournal Article20160614Fandoghlu forest is located in the north west of Ardabil city.
