Turkish Journal of Botany
The endemic Onosma bracteosum Hausskn. & Bornm. (Boraginaceae) was investigated morphologically, anatomically and ecologically. It has setae with tuberculate bases. The stem is 15-35 cm tall and erect. The leaves are equifacial and amphistomatous. Stomata cells are anisocytic and anomocytic. The stomata index is 21.25 for the upper epidermis and 25 for the lower epidermis. This plant generally prefers sandy-loamy, sandy-clayey and loamy soils. In the soil samples, the N (23%), P (26%) and K (27%) concentrations were lower in the generative periods than in the vegetative periods. According to the results of plant nutrient analysis, N% (1.140-3.274), P% (0.172-0.403) …

Field and laboratory investigations on the ecology, reproduction and behavior of Spermophilus citellus and Spermophilus xantophrymnus were performed over a period of 4 years. Both S. citellus and S. xanthophrymnus are diurnal species and occupy semiarid steppe areas in Turkish Thrace and Anatolia, respectively. Distribution of the former species is confined to restricted steppe areas in Turkish Thrace whilethe, latter lives on the Anatolian steppe, and is sympatric with Meriones tristami, Mesocricetus brandthi, Allactaga williamsi and Microtus spp. The burrows of both species have one entrance, and are built separately in the field. They constitute small social colonies and communicate …
