Sympetrum flaveolum (Odonata: Libellulidae) a new species record for Iran
راسته Odonata شامل آسیابک‌ها و سنجاقک‌های آبزی و شکارگر است که گاهی به‌عنوان عوامل کنترل بیولوژیک و همچنین شاخص اکولوژیکی کیفیت اکوسیستم‌های آبی مطرح می‌شوند. در این تحقیق طی نمونه‌برداری از منطقه شمال غربی استان اصفهان، گونه Sympetrum flaveolum (Linnaeus) از شهر چادگان، جمع‌آوری و شناسایی شد و سپس به تأیید نگارنده سوم رسید. گونه فوق برای اولین‌بار از ایران گزارش می‌شود.
متن کاملThe effects of wind speed, competition, and body size on perch height selection in a guild of Libellulidae species (Odonata)
For eleven species of sympatric libellulids, male mean mass was positively correlated with wing aspect ratio, wing loading, and mean perch height. We tested the hypo theses that perch height selection was governed by interspecific competition or biomechanical responses to increased wind speed at higher perches. Although larger odonates might prefer higher perches to offset their increased wing ...
متن کاملDYNAMIC COMPLEXITY OF A THREE SPECIES COMPETITIVE FOOD CHAIN MODEL WITH INTER AND INTRA SPECIFIC COMPETITIONS
The present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. The behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. Boundedness and dissipativeness of the system are e...
متن کاملDNA Barcoding of selected dragonfly species ( Libellulidae and Aeshnidae ) for species authentication with phylogenetic assessment
Dragonflies are the bio indicators of the aquatic ecosystem. Knowledge and studies on the diversity of dragonflies in India is very high. Identification by traditional taxonomy often leads to misidentification. Incidence of sexual dimorphism is found to be high particularly in the Libellulidae and Aeshnidae family. In order to resolve the above mentioned problem, the accurate identification of ...
