Bretschneidera sinensis Hemsl., a relic of the ancient Tertiary tropical flora endemic to Asia, is one of the Chinese class-I protected wild plants. Sporadically distributed in mountain forests of provinces south of the Yangtze River in China, it has recently also been found in Myanmar, Thailand, and northern Vietnam. As an ancestral specie... -
2018-02-11Genomic signature of adaptive divergence despite strong non-adaptive forces on edaphic islands: a case study of Primulina juliaeBoth genetic drift and divergent selection are expected to be strong evolutionary forces driving population differentiation on edaphic habitat islands .Populations with the lowest genetic variation were most genetically differentiated from other populations and the extent of genetic drift increased with geographic distance from other populations...Read More
Both genetic drift and divergent selection are expected to be strong evolutionary forces driving population differentiation on edaphic habitat islands. However, the relative contribution of genetic drift and divergent selection to population divergence has rarely been tested simultaneously. In this study, RAD-based population genomic analys... -
2018-02-05Evolutionary transitions from distyly to homostyly: the ecological correlates and genetic consequencesHeterostyly is an adaptation found in numerous families that enables outbreeding in dioecious flowers , complementing self-incompatibility mechanisms .Identifying the environmental conditions favouring transitions to selfing and determining their population genetic consequences can provide insights into how often and why selfing evolves in heter... Heterostyly is an adaptation found in numerous families that enables outbreeding in dioecious flowers, complementing self-incompatibility mechanisms. However, an evolutionary transition to homostyly with high levels of self-fertilization is frequently seen, with consequences for the genetic structure, evolution and adaptation of the species. The...Read More

2018-01-10Exogenous nitrogen addition reduced the temperature sensitivity of microbial respiration without altering the microbial community compositionAtmospheric nitrogen ( N ) deposition is changing in both load quantity and chemical composition .The consistent N effects for the surface and subsurface soils suggest that the effects of N on soil microbial communities may be independent of soil chemical contents and stoichiometry .Fig . The temperature sensitivity ( Q10 ) of soil CO2 emission ...Read More
Atmospheric nitrogen (N) deposition is changing in both load quantity and chemical composition. The load effects have been studied extensively, whereas the composition effects remain poorly understood. We conducted a microcosm experiment to study how N chemistry affected the soil microbial community composition characterized by phospholipid... -

2017-12-21Effect of climate and competition on radial growth of Pinus massoniana and Schima superba in China’s subtropical monsoon mixed forestTree growth is affected by many exogenous and endogenous factors , especially climate and competition .Dendroclimatology combined with competition analysis was used to examine the radial growth response of two major species - Pinus massoniana and Schima superba in subtropical monsoon mixed forests in southern China . Growth-climate relationship ...Read More
Tree growth is affected by many exogenous and endogenous factors, especially climate and competition. To address the issue of how these factors influence tree growth under global warming, dendroclimatology combined with competition analysis was used to examine the radial growth response of two major species - Pinus massoniana and Schima sup...
