2018-11-21Reduced geographical variability in spring phenology of temperate trees with recent warmingAdvancements of spring phenology due to climate warming have been observed worldwide in the last decades , however .We addressed this question through analyzing temporal changes in the geographical variability for 22 spring phenological events ( both leaf-out and flowering phenology ) of 16 temperate tree species in Europe . This study , for the... Advancements of spring phenology due to climate warming have been observed worldwide in the last decades, however, whether the occurrence of species-specific phenology events among populations over broad space has been converged or diverged with recent warming has been little explored. We addressed this question through analyzing temporal change...Read More -

However , the observed responses to increased acid inputs are quite variable among different forest soils .Long-term observation data showed that the pH of an old evergreen broadleaved forest ( BF ) soils maintained around 3.8 under high rate of ... Elevated anthropogenic acid deposition has accelerated forest soil acidification in southern China. However, the observed responses to increased acid inputs are quite variable among different forest soils. Long-term observation data showed that the pH of an old evergreen broadleaved forest (BF) soils maintained around 3.8 under high rate of acid...Read More -

2018-10-09To keep pace with the “neighbor”: Pollination niche availability facilitates colonization of Guettarda speciosa with heteromorphic self-incompatibility on oceanic islandsGuettarda speciosa is a dominant woody plant on Xisha Islands , widely distributing on tropical and subtropical oceanic islands .Self-pollinated plants get pollination niche from themselves , and wind pollinated plants get pollination niche from wind , and animal pollinated plants get from pollinator .How to prove this hypothesis ? Similarly to ... Guettarda speciosa is a dominant woody plant on Xisha Islands, widely distributing on tropical and subtropical oceanic islands. As a typical island plant, it is a favorable species to study evolutional ecology questions relating to plants long distance dispersal. According our research data on Xisha Island, G. speciosa is an obligate out breedin...Read More -
2018-09-29Homeologue-specific expression divergence in the recently formed tetraploid Capsella bursa-pastoris (Brassicaceae)Following allopolyploid formation , extensive genome evolution occurs , with the eventual loss of many homeologous gene copies .Despite the lack of evident population structure , Asian populations experience highly divergent environmental conditions .Orientalis accessions are included in ( a ) , but excluded in ( b ) . ( c ) PCA on total express... Following allopolyploid formation, extensive genome evolution occurs, with the eventual loss of many homeologous gene copies. Although this process of diploidization has occurred many times independently, the evolutionary forces determining the probability and rate of gene loss remain poorly understood. Capsella bursa-pastoris is a recently deri...Read More -
