BACKGROUND AND AIMS Genetic drift due to geographical isolation, gene flow and mutation rates together make it difficult to determine the evolutionary relationships of present-day species. In this study, population genetic data were used to model and decipher interspecific relationships, speciation patterns and gene flow between three species of spruce with similar morphology, Picea wilsonii, P. neoveitchii and P. morrisonicola. Picea wilsonii and P. neoveitchii occur from central to north-west… Expand
Origin and speciation of Picea schrenkiana and Piceasmithiana in the Center Asian Highlands and Himalayas
TLDR
The results highlight the complex speciation histories of these alpine conifers due to interspecific gene flow and/or incomplete lineage sorting, and the importance of the early QTP uplifts in promoting the origin of these important conifer species in the Asian highlands. Expand
Polyphyly and species delimitation of Picea brachytyla (Pinaceae) based on population genetic data
Accurate species delimitation is fundamental to biodiversity conservation. The endangered spruce Picea brachytyla (Franch.) E. Pritz. was suggested to be polyphyletic based on a limited number ofExpand
Effects of Geological and Environmental Events on the Diversity and Genetic Divergence of Four Closely Related Pines: Pinus koraiensis, P. armandii, P. griffithii, and P. pumila
TLDR
This study investigated the levels and patterns of nucleotide diversity and interspecific divergence in four closely related pines in China and suggested that mountain uplift and geological climate oscillations may have led to the patterns of genetic divergence and nucleotide variations in these four pine species. Expand
Late Pleistocene climate change promoted divergence between Picea asperata and P. crassifolia on the Qinghai–Tibet Plateau through recent bottlenecks
TLDR
The reduced population sizes and the divergent selection may together have triggered the initial divergence under high gene flow between these two species, highlighting the importance of climatic oscillations during the late Pleistocene in promoting speciation through changing demographic sizes of the ancestral species on the QTP and in adjacent regions. Expand
Mitochondrial introgression and complex biogeographic history of the genus Picea.
TLDR
This study reinvestigated the phylogenetic and biogeographic history of Picea, a main component of the Northern Hemisphere forest with many species that originated from recent radiation, using two chloroplast, one mitochondrial, one nuclear and three single-copy nuclear gene markers to demonstrate the importance of applying data from three genomes for a clear understanding of evolutionary histories in the pine family. Expand
Determining the extent and direction of introgression between three spruce species based on molecular markers from three genomes with different rates of gene flow
TLDR
The results support the hypotheses that introgressions occurred more frequently at genetic markers with lower rates of gene flow and that they usually took place from local species towards invading species that had undergone recent demographic expansion. Expand
Population genomic analysis reveals that homoploid hybrid speciation can be a lengthy process
TLDR
This study emphasizes the power of population genomic analysis combined with coalescent analysis for reconstructing the stages involved in the origin of a homoploid hybrid species over an extended period and shows that these stages can in some instances span a relatively long period of evolutionary time. Expand
Genomic evidence for polyphyletic origins and interlineage gene flow within complex taxa: a case study of Picea brachytyla in the Qinghai‐Tibet Plateau
TLDR
The phylogenomic analyses suggest that the sampled trees of P. brachytyla cluster into two distinct lineages corresponding to the two taxonomically recognized intraspecific varieties, and abba‐baba and ∂a∂i analyses suggests that gene flow between these two independently evolved lineages has been extensive and bidirectional. Expand
Mitochondrial DNA and microsatellite analyses reveal strong genetic differentiation between two types of estuarine tapertail anchovies (Coilia) in Yangtze River Basin, China
TLDR
The genetic structure of these species was studied by analyzing the mitochondrial gene cytochrome b (Cyt b) and polymorphic microsatellite loci in 184 anchovies and discriminated their migratory life history using otolith microchemical analysis, and the presence of hybridization between the two closely related sister species was revealed. Expand
Contrasting responses to Pleistocene climate changes: a case study of two sister species Allium cyathophorum and A. spicata (Amaryllidaceae) distributed in the eastern and western Qinghai–Tibet Plateau
TLDR
Analysis of chlorotype diversity showed that A. spicata, the species occurring in the western QTP, contains much lower genetic diversity than A. cyathophorum, indicating a contrasting pattern of responses to Pleistocene climate changes, and highlights the importance of geographical topography in determining how species responded to the climate changes that took place in the QTP during the Pleists.

GENE FLOW AND SPECIES DELIMITATION: A CASE STUDY OF TWO PINE SPECIES WITH OVERLAPPING DISTRIBUTIONS IN SOUTHEAST CHINA
TLDR
The hypothesis that high intraspecific gene flow has accelerated cpDNA lineage sorting between these two pine species is supported and cpDNA variation across these two Pine species is more species specific than mtDNA variation and almost delimits taxonomic boundaries. Expand
Contrasting phylogeographical patterns between mainland and island taxa of the Pinus luchuensis complex
TLDR
The high heterogeneity of genetic composition for island populations is likely to be associated with a history of multiple colonization from the mainland, and the spatial apportionment of organelle DNA polymorphisms is consistent with a pattern of stepwise colonization on island populations. Expand
Molecular phylogeny and biogeography of Picea (Pinaceae): implications for phylogeographical studies using cytoplasmic haplotypes.
TLDR
It is suggested that Picea originated in North America, and that its present distribution could stem from two times of dispersal from North America to Asia by the Beringian land bridge, and then from Asia to Europe. Expand
Direction and extent of organelle DNA introgression between two spruce species in the Qinghai-Tibetan Plateau.
TLDR
The results underscore cryptic introgressions of organelle DNAs in plants and the importance of considering rates of gene flow and range shifts to predict direction and extent of interspecific genetic exchanges. Expand
Progenitor-derivative speciation in Pozoa (Apiaceae, Azorelloideae) of the southern Andes.
TLDR
All facts support that Pozoa represents a good example of progenitor-derivative speciation in the Andes of southern South America. Expand
Molecular phylogeography and evolutionary history of Picea likiangensis in the Qinghai–Tibetan Plateau inferred from mitochondrial and chloroplast DNA sequence variation
TLDR
The results of the present study highlight the evolutionary complexity of a widely distributed species owing to interactions among local and edge expansion, long‐distance dispersal, and intraspecific divergences at two sets of DNA genomes with different rates of gene flow. Expand

TLDR
It is found that cpDNA variation, although far from being fully diagnostic, is more species‐specific than mtDNA variation: four groups of populations were identified using cpDNA markers, all of them related to species or groups of species, whereas for mtDNA, geographical variation prevails over species differentiation. Expand
Trans-species shared polymorphisms at orthologous nuclear gene loci among distant species in the conifer Picea (Pinaceae): implications for the long-term maintenance of genetic diversity in trees.
TLDR
It is suggested that trans-species shared polymorphisms might be frequent at plant nuclear gene loci, leading to high allelic diversity, more likely in trees and plants characterized by ecological and life-history determinants favoring large population sizes such as an outcrossing mating system, wind pollination, and a dominant position in ecosystem.

TLDR
Re-sequencing of nuclear loci in four spruce species suggests that North American and Eurasian species might have been geographically much closer in the recent past than they are today. Expand

TLDR
A population genetic analysis of Acer takesimense, an anagenetically derived species endemic to Ullung Island, Korea, and its continental progenitor A. pseudosieboldianum implies that anagenetic speciation leads to a different pattern of specific and genetic diversity than often seen with cladogenesis.
