The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in
the world. Phylogenetic, phylogeographic, and ecological studies support plant …

Our understanding of homoploid hybrid speciation has advanced substantially since this
mechanism of species formation was codified 50 years ago. Early theory and research …

Even before the publication of Darwin's Origin of Species, the perception of evolutionary
change has been a tree-like pattern of diversification-with divergent branches spreading …

As the highest and largest plateau in the world, the Qinghai–Tibet Plateau, with its numerous
endemic species, is one of the important alpine biodiversity hotspots. Only recently have the …

Homoploid hybrid speciation is the origin of a hybrid species without change in chromosome
number. Although currently thought to be a rare form of speciation, especially relative to the …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

Abstract The Qinghai‐Tibetan Plateau (QTP) is thought to be more strongly affected by the
Quaternary glaciations than most other regions of the same latitude. It would be of great …

Phylogenetic relationships among Pinus species from subgenus Strobus remain unresolved
despite combined efforts based on nrITS and cpDNA. To provide greater resolution among …

How coniferous trees in northern China changed their distribution ranges in response to
Quaternary climatic oscillations remains largely unknown. Here we report a study of the …

Altitudinal gradients are characterized by steep changes of the physical and biotic
environment that present challenges to plant adaptation throughout large parts of the world …
