در این مطالعه ریخت شناسی هندسی جنس erodiontes با استفاده از تکنیک فوریه بیضوی انجام شد. چهار جمعیت از چهار جمعیت چارطاقی، ابوزیدآباد، مصر و حجت آباد از دو گونه e. aelleni و e. pfaundleri انجام شد . هدف این مطالعه این بود که تاثیر ویکاریانس بر جمعیت های این دو گونه بررسی شود. نتایج نشان داد که تفاوت شکل بین جمعیت های هم گونه بسیار اندک است. این مساله ممکن است نشان دهنده این نکته باشد که جدایی ای...

Background Few studies of edge effects on wildlife objectively identify habitat edges or explore non-linear responses. In this paper, we build on ground beetle (Coleoptera: Carabidae) research that has begun to address these domains by using triangulation wombling to identify boundaries in beetle community structure and composition at the edges of forest patches with residential developments. W...

Tiger beetles are fast diurnal predators capable of chasing prey under closed-loop visual guidance. We investigated this control system using statistical analyses of high-speed digital recordings of beetles chasing a moving prey dummy in a laboratory arena. Correlation analyses reveal that the beetle uses a proportional control law in which the angular position of the prey relative to the beetl...

One of the leitmotifs of the ecophysiological research on ectotherms is the variation and evolution of thermal reaction norms for biological rates. This long-standing issue is crucial both for our understanding of life-history diversification and for predicting the phenology of economically important species. A number of properties of the organism's thermal phenotype have been identified as pot...
