A lottery model of density-dependent selection in evolutionary genetics
Fitness is typically represented in heavily simplified terms in evolutionary genetics, often using constant selection coefficients, to make it easier to infer or predict how type frequencies change over time. This excludes fundamental ecological factors such as dynamic population size or density-dependence from the most genetically-realistic treatments of evolution, a problem that inspired MacA...
متن کاملSelection of energy source and evolutionary stable strategies for power plants under financial intervention of government
Currently, many socially responsible governments adopt economic incentives and deterrents to manage environmental impacts of electricity suppliers. Considering the Stackelberg leadership of the government, the government’s role in the competition of power plants in an electricity market is investigated. A one-population evolutionary game model of power plants is developed to study how their pro...

در این تحقیق به مطالعه وجود انتخاب نامساعد(کژ گزینی) در بازار بیمه درمان تکمیلی ایران پرداخته شده است. داده های مورد نیاز توسط پرسشنامه و به روش نمونه گیری خوشه ای جمع آوری شده است. پرسشنامه ها در میان افراد شاغل ساکن شهر تهران توریع شد. در این تحقیق با استفاده از تخمین دو مدل لجستیک و به دست آوردن ضریب همبستگی میان تقاضای بیمه درمان تکمیلی و رخداد خسارت به بررسی موضوع مورد نظر پرداخته شده است....
15 صفحه اولThe ecological–evolutionary interplay: density-dependent sexual selection in a migratory songbird
Little is understood about how environmental heterogeneity influences the spatial dynamics of sexual selection. Within human-dominated systems, habitat modification creates environmental heterogeneity that could influence the adaptive value of individual phenotypes. Here, we used the gray catbird to examine if the ecological conditions experienced in the suburban matrix (SM) and embedded suburb...
متن کاملDensity-dependent selection closes an eco-evolutionary feedback loop in the stick insect Timema cristinae.
Empirical demonstrations of feedbacks between ecology and evolution are rare. Here, we used a field experiment to test the hypothesis that avian predators impose density-dependent selection (DDS) on Timema cristinae stick insects. We transplanted wild-caught T. cristinae to wild bushes at 50 : 50 cryptic : conspicuous morph ratio and manipulated density by transplanting either 24 or 48 individu...
