How can distinct egg polymorphism be maintained in the rufescent prinia (Prinia rufescens)–plaintive cuckoo (Cacomantis merulinus) interaction—a modeling approach
In avian brood parasitism, both the host and the parasite are expected to develop various conflicting adaptations; hosts develop a defense against parasitism, such as an ability to recognize and reject parasitic eggs that look unlike their own, while parasites evolve egg mimicry to counter this host defense. Hosts may further evolve to generate various egg phenotypes that are not mimicked by pa...

Department of Zoology, Faculty of Life Sciences, Tel Aviv University, Ramat Aviv, Tel Aviv 69978, Israel occurrence, and a payoff is listed at the end of each path. A rejection strategy is adaptive if !Js overall payoff is greater than that of an acceptance strategy. In either case (egg or nestling recognition), if an acceptor is parasitized by a common cuckoo (a probability of P), its reproduc...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Do life - history variables of European cuckoo hosts explain their egg - rejection behavior ?
Recently, Brooker and Brooker suggested an equilibrium in the level of host defense and parasite counter-defense despite the passage of sufficient time for the evolution of host defenses through coevolution between brood parasites and their hosts. A long coevolutionary history of brood parasitism and nest predation has favored an adjustment of the host’s life-history pattern to the point where ...
