Montane cloud forests (MCFs), with their isolated nature, offer excellent opportunities to study the long-term effects of habitat fragmentation and the impacts of climate change. Quercus arbutifolia is a rare oak in MCFs of southern China and Vietnam. Its isolated populations, small population size and unique ecological niche make this species vulnerable to climate change and habitat loss. In this study, we used chloroplast (cpDNA) and nuclear (ITS) DNA sequences to investigate genetic… Expand

Predicting climate change impacts on the threatened Quercus arbutifolia in montane cloud forests in southern China and Vietnam: Conservation implications
Abstract Trees of montane cloud forests (MCFs) often have small and isolated populations and face numerous threats. Due to limited conservation resources, management decisions are often based onExpand
Genetic diversity and demographic analysis of an endangered tree species Diplopanax stachyanthus in subtropical China: implications for conservation and management
TLDR
Light is shed on the evolutionary history of D. stachyanthus in subtropical China, and the genetic differentiation is extremely high among the three lineages and among populations; most of the ten populations fixed private haplotype(s). Expand
Seed germination schedule and environmental context shaped the population genetic structure of subtropical evergreen oaks on the Yun-Gui Plateau, Southwest China
TLDR
Seed traits and environmental heterogeneity are identified as two key drivers that shape the population genetic structure of EBLF trees in Southwest China and should be considered in regional forestry conservation and management. Expand
Ancient events and climate adaptive capacity shaped distinct chloroplast genetic structure in the oak lineages
TLDR
This study investigated whether closely related Quercus lineages have similar spatial genetic structures and moreover, what roles have their geographic distribution, ecological tolerance, and historical environmental changes played in the similar or distinct genetic structures. Expand
Ancient east-west divergence, recent admixture, and multiple marginal refugia shape genetic structure of a widespread oak species (Quercus acutissima) in China
TLDR
The genetic structure and demographic history of Q. acutissima indicates the possibility of central-marginal dispersal dynamics along latitude and existence of multiple refugia at distribution edges, and highlights that the stepped geomorphology in China and climatic changes since the Pliocene play an important role in shaping the intraspecific genetic structure of widespread species in East Asia. Expand
Combined genotype and phenotype analyses reveal patterns of genomic adaptation to local environments in the subtropical oak Quercus acutissima
TLDR
The hypothesis of local adaptation of this long‐lived oak tree of subtropical China is validated, and environment was found to have a significant and stronger impact on the non‐neutral than the neutral SNPs, and also significantly associated with the phenotypic differentiation, suggesting that, apart from the geography, environment had played a role in determining non‐ neutral and phenotypesic variation.

The Application and Limitation of Universal Chloroplast Markers in Discriminating East Asian Evergreen Oaks
TLDR
Test whether the four chloroplast markers atpI-atpH, matK, psbA-trnH, and ycf1, can discriminate the two evergreen oak sections in Asia – Cyclobalanopsis and Ilex and found that universal chloroblast DNA (cpDNA) barcoding markers could resolve two clades in Quercus. Expand
The complete chloroplast genome of a critically endangered tree species in China, Cyclobalanopsis obovatifolia (Fagaceae)
TLDR
The maximum likelihood (ML) phylogenetic analysis showed that C. obovatifolia and Quercus edithiae were clustered into one clade with strong support values, indicating their closer relationship. Expand
Severe Plastid Genome Size Reduction in a Mycoheterotrophic Orchid, Danxiaorchis singchiana, Reveals Heavy Gene Loss and Gene Relocations
TLDR
The complete plastome of D. singchiana was sequenced and the majority of the presumably intact protein-coding genes seem to have undergone purifying selection, and only the psaC gene was positively selected when compared to that in Cr. Expand
How Can Botanical Gardens Support Sustainable Urban Development? A Case Study of Shanghai Chenshan Botanical Garden
TLDR
The role of Chenshan Botanical Garden in the sustainable development of Shanghai City in the last six years is described and perspectives on future plant conservation and sustainable utilization are provided. Expand

Phylogeography of Quercus glauca (Fagaceae), a dominant tree of East Asian subtropical evergreen forests, based on three chloroplast DNA interspace sequences
TLDR
Haplotype spatial distribution, ENM, mismatch distribution, and neutrality tests suggest that Q. glauca in Southeast China experiences expansion, and the current distribution in region III might be shaped by southward expansion from regions I and II after last glacial maximum (LGM). Expand
Phylogeography of Quercus variabilis Based on Chloroplast DNA Sequence in East Asia: Multiple Glacial Refugia and Mainland-Migrated Island Populations
TLDR
It is shown that geographical heterogeneity combined with climate and sea-level changes have shaped the genetic structure of this wide-ranging tree species in East Asia. Expand
Chloroplast diversity and population differentiation of Castanopsis fargesii (Fagaceae): a dominant tree species in evergreen broad-leaved forest of subtropical China
TLDR
Subtropical forests in China constitute the major expanse of evergreen broad-leaved forest in East Asia and contraction-expansion process was detected in the west, center, and east regions, indicating that geomorphological remodeling together with climatic changes in the Pleistocene had strong impact on genetic structure of C. fargesii. Expand
Population genetic diversity and structure of Dipteronia dyerana (Sapindaceae), a rare endemic from yunnan province, China, with implications for conservation
TLDR
The authors' data indicate that the ex situ conserved population insufficiently represents the genetic diversity present in the species, and it is suggested to sample at least four natural populations to cover a reasonable proportion of the species' genetic variation for ex situ conservation. Expand
Molecular phylogeography and ecological niche modelling of a widespread herbaceous climber, Tetrastigma hemsleyanum (Vitaceae): insights into Plio-Pleistocene range dynamics of evergreen forest in subtropical China.
TLDR
The findings suggest relative demographic stability of this biome in China over the last glacial-interglacial cycle, in contrast with palaeobiome reconstructions showing that this forest biome retreated to areas of today's tropical South China during the LGM. Expand
Marked genetic divergence among sky island populations of Sedum lanceolatum (Crassulaceae) in the Rocky Mountains.
TLDR
Genetic differentiation in S. lanceolatum was most likely a product of short-distance elevational migration in response to climate change, low seed dispersal, and vegetative reproduction, and paleoclimatic cycles were probably a major factor preserving genetic variation and promoting divergence in high-elevation flora of the Rocky Mountains.

Phylogeography of the South China Field Mouse (Apodemus draco) on the Southeastern Tibetan Plateau Reveals High Genetic Diversity and Glacial Refugia
TLDR
This study supported the hypothesis that the SEMTP was a large late Pleistocene refugium, and further inferred that the Gongga Mountain Region and Hongya County were glacial refugia for A. draco. Expand
Initial diversification, glacial survival, and continuous range expansion of Gentiana straminea (Gentianaceae) in the Qinghai–Tibet Plateau
TLDR
Findings imply that G. straminea should have experienced initial diversification, glacial survival on the platform, and continuous expansion to the QTP edge during the glacial period. Expand
Phylogeography of Quercus phillyraeoides (Fagaceae) in Japan as revealed by chloroplast DNA variation
TLDR
Largest genetic differentiation across the populations in the Seto Inland Sea region suggests that these areas have been recently colonized following the last glacial maximum from the refugia in the Pacific coast or in southern Kyushu. Expand
Molecular data and ecological niche modelling reveal a highly dynamic evolutionary history of the East Asian Tertiary relict Cercidiphyllum (Cercidiphyllaceae).
TLDR
The findings challenge the notion of relative evolutionary and demographic stability of Tertiary relict trees, and may serve as a guideline for assessing the impact of Neogene climate change on the evolution and distribution of East Asian temperate plants. Expand
