Siring success and paternal effects in heterodichogamous Acer opalus.
BACKGROUND AND AIMS Heterodichogamy (a dimorphic breeding system comprising protandrous and protogynous individuals) is a potential starting point in the evolution of dioecy from hermaphroditism. In the genus Acer, previous work suggests that dioecy evolved from heterodichogamy through an initial spread of unisexual males. Here, the question is asked as to whether the different morphs in Acer o...
متن کاملDisassortative mating, sexual specialization, and the evolution of gender dimorphism in heterodichogamous Acer opalus.
In sexually polymorphic species, the morphs are maintained by frequency-dependent selection through disassortative mating. In heterodichogamous populations in which disassortative mating occurs between the protandrous and protogynous morphs, a decrease in female fitness in one morph is hypothesized to drive sexual specialization in the other morph, resulting in dimorphic populations. We test th...
متن کاملVariation in annual and lifetime reproductive success of lance-tailed manakins: alpha experience mitigates effects of senescence on siring success.
The causes of variation in individual reproductive success over a lifetime are not well understood. In long-lived vertebrates, reproductive output usually increases during early adulthood, but it is difficult to disentangle the roles of development and learning on this gain of reproductive success. Lekking lance-tailed manakins provide an opportunity to separate these processes, as the vast maj...

تجارت الکترونیکی شیوه اجرای مسئولیتها، تقابل با مشتریان و امور معمول عملیاتی در شرکتها را تغییر داده است. تجارت الکترونیکی در عمل تنها خرید و فروش کالاها را از طریق ابزار الکترونیک نمی باشد، بلکه تمام فعالیتهای لازم جهت انجام فرایند فروش را نیز در بر میگیرد. در اواخر دهه 1990 بسیاری از شرکتها فعالیتهای خود را به منظور دستیابی به مشتریان جدید و یا ارائه فرصتهای جدید به مشتریان موجود گسترش دادند...
Artificial Night Lighting Affects Dawn Song, Extra-Pair Siring Success, and Lay Date in Songbirds
Associated with a continued global increase in urbanization, anthropogenic light pollution is an important problem. However, our understanding of the ecological consequences of light pollution is limited. We investigated effects of artificial night lighting on dawn song in five common forest-breeding songbirds. In four species, males near street lights started singing significantly earlier at d...
