گونه گیاهی Hypericum dogonbadanicum بعنوان گونه جدید برای دانش گیاهی از جنوب ایران نامگذاری و توضیح داده می‌شود. نزدیکترین گونه به گونه فوق H. balearicum L.از بخش Psorophytum (Spach) Nyman تشخیص داده می‌شود، لیکن به علت وجود گلبرگ‌ها و پرچم‌های با دوام ضرورت نامگذاری بخش جدیدی برای این گونه مورد توجه قرار می‌گیرد. علاوه بر این گونه‌های گیاهی: Allium szovitsii, Arabis christiana, Briza humilis,...
Biosynthetic Potential of Actinomycetes from Helianthemum stevenii Rupr. Ex Juz. & Pozd. Rhizosphere
during 2010-2011 a faunistic survey was carried out for collection and identification of edaphic mesostigmatic mites (acari: mesostigmata) in jiroft and suburb. mites were extracted from soil samples by berlese funnel. the mites were cleared in nesbit fluid and were mounted in hoyer medium on microscopic slides. in this study 43 spices from 26 genera and 16 families were collected and identifie...
BACKGROUND AND AIMS Environmental variability at several scales can determine plant reproductive success. The main goal of this work was to model the reproductive flexibility of a semi-arid specialist considering different scales of environmental variability. METHODS A 2-year field study was performed on the determinants of the female reproductive success of Helianthemum squamatum, an Iberian...
Abstract Natural selection is the major force driving adaptive evolution in natural populations, varying strength, direction, and form through space time, especially highly variable environments such as Mediterranean ecosystems. Although a conservative resource‐use strategy has been hypothesized to be taxa, patterns of at intraspecific level, that is, suite traits determining individual fitness...
