Turkish Journal of Zoology

During a field excursion in eastern Turkey and the Zanjan province of Iran, 9 rodent species were captured, and the diploid number of chromosomes (2n), the number of autosomal arms (FNa) and the fundamental number (FN) were determined for these species. Microtus schidlovskii with 2n = 60 and FNa = 58 was recorded for the first time from Özalp (Van) and Yüksekova (Hakkari). The karyological record of Meriones vinogradovi in Turkey was also given for the first time. The karyological results were determined as follows: Spermophilus xanthophrymnus (2n = 42, FNa = 78, FN = 82 in Turkey), Mesocricetus brandti …


Time Trend In The Mean Annual Temperature Of Iran, Bijan Ghahraman Jan 2006

Time Trend In The Mean Annual Temperature Of Iran, Bijan Ghahraman

Turkish Journal of Agriculture and Forestry

Many researchers around the world have reported a gradual increase in mean annual temperature. Yet, there are some reports of a reduction in this parameter. In this study, we investigated the long-term trend of mean annual temperature at 34 synoptic stations in Iran (2 stations in cool humid climates, 14 stations in temperate humid climates, 11 stations in steppe climates, and 7 stations in desert climates, based on the Koppen climatic division) with a minimum record of 30 years by Student's t-test. Results showed that there was a positive trend in 50% of the stations, while 41% of stations had …


Karyotype Of Persian Chub, Petroleuciscus Persidis (Coad, 1981) (Actinopterygii: Cyprinidae) From Southern Iran, Hamid Reza Esmaeili, Zeinab Piravar Jan 2006

Karyotype Of Persian Chub, Petroleuciscus Persidis (Coad, 1981) (Actinopterygii: Cyprinidae) From Southern Iran, Hamid Reza Esmaeili, Zeinab Piravar

Turkish Journal of Zoology

The diploid chromosome number of Persian chub, Petroleuciscus persidis (Coad, 1981), was 2n = 50, comprising 29 metacentric, 18 submetacentric, and 3 subtelocentric chromosomes and the number of arms was 97. A detailed karyotype of this endemic cyprinid fish of southern Iran was established for the first time in this study.


On The Circumscription Of Isatis Tinctoria L. (Brassicaceae) In Iran, Hamid Moazzeni, Shahin Zarre Jan 2006

On The Circumscription Of Isatis Tinctoria L. (Brassicaceae) In Iran, Hamid Moazzeni, Shahin Zarre

Turkish Journal of Botany

In the course of preparing a revision of Isatis L. and its allies in Iran, we verified Isatis tinctoria L. among the material studied. Although it has been previously recorded for Iran, we give a more extensive description and a map of its distribution in Iran. A key to distinguishing this species from its allies and a discussion of the affinities in this group are provided.
