Long-branch attraction in species tree estimation: inconsistency of partitioned likelihood and topology-based summary methods
With advances in sequencing technologies, there are now massive am-ounts of genomic data from across all life, leading to the possibility that arobust Tree of Life can be constructed. However, “gene tree heterogeneity”,which is when different genomic regions can evolve differently, is a commonphenomenon in multi-locus datasets, and reduces the accuracy of standardmethods for...
متن کاملLong-Branch Attraction Bias and Inconsistency in Bayesian Phylogenetics
Bayesian inference (BI) of phylogenetic relationships uses the same probabilistic models of evolution as its precursor maximum likelihood (ML), so BI has generally been assumed to share ML's desirable statistical properties, such as largely unbiased inference of topology given an accurate model and increasingly reliable inferences as the amount of data increases. Here we show that BI, unlike ML...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولInconsistency of Species Tree Methods under Gene Flow.
Coalescent-based methods are now broadly used to infer evolutionary relationships between groups of organisms under the assumption that incomplete lineage sorting (ILS) is the only source of gene tree discordance. Many of these methods are known to consistently estimate the species tree when all their assumptions are met. Nonetheless, little work has been done to test the robustness of such met...
