Multivariate intralocus sexual conflict in seed beetles.
Intralocus sexual conflict (IaSC) is pervasive because males and females experience differences in selection but share much of the same genome. Traits with integrated genetic architecture should be reservoirs of sexually antagonistic genetic variation for fitness, but explorations of multivariate IaSC are scarce. Previously, we showed that upward artificial selection on male life span decreased...
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
15 صفحه اولStrong sexual selection in males against a mutation load that reduces offspring production in seed beetles.
Theory predicts that sexual reproduction can increase population viability relative to asexual reproduction by allowing sexual selection in males to remove deleterious mutations from the population without large demographic costs. This requires that selection acts more strongly in males than females and that mutations affecting male reproductive success have pleiotropic effects on population pr...
متن کاملVariation in selection, phenotypic plasticity, and the ecology of sexual size dimorphism in two seed-feeding beetles
Most animals show some degree of sexual size dimorphism. However, the degree and direction of dimorphism vary substantially among taxa and even among populations within species. Major progress has been made in the study of sexual size dimorphism in the last decade. Yet detailed studies on the proximate and ultimate causes of sexual size dimorphism in a single animal taxon are few (e.g. Chapters...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
