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 -
2018-09-11Stoichiometry controls asymbiotic nitrogen fixation in a nitrogen-saturated forestLowland tropical forests with chronic nitrogen ( N ) deposition and/or abundant N-fixing organisms are commonly rich in N relative to other nutrients .The tropical N richness introduces a paradoxical relationship in which many tropical forests sustain high rates of asymbiotic N fixation despite the soil N richness and the higher energy cost of N... Lowland tropical forests with chronic nitrogen (N) deposition and/or abundant N-fixing organisms are commonly rich in N relative to other nutrients. The tropical N richness introduces a paradoxical relationship in which many tropical forests sustain high rates of asymbiotic N fixation despite the soil N richness and the higher energy cost of N f...Read More -

2018-08-27Formation pattern in five types of pollen tetrad in Pseuduvaria trimera (Annonaceae)Pollen is a male germ cell carrying genetic information , and its morphology has strong genetic conservatism .The nucleus location of the microspores together with cytokinesis determine the number and the spatial arrangement of callose plates , and further have an effect on the tetrad types .Our observations of the development of tetrads provide... Pollen is a male germ cell carrying genetic information, and its morphology has strong genetic conservatism. In angiosperms, in addition to the single pollen, there aredyads, tetrads, octads and polyads. In entomophilous plants, polyads ensures that pollinators can carry a larger amount of pollen at one time, increasing the fertilization rate wi...Read More -

2018-08-17A New Hypothesis On Plant Acclimation DevelopedAnthropogenic nitrogen ( N ) deposition has accelerated terrestrial N cycling at regional and global scales , causing nutrient imbalance in many natural and semi-natural ecosystems .Dr . Xiankai Lu and his colleagues conducted an experiment employing a long-term N addition to examine ecosystem responses and plant acclimation to added N in an N-r...Read More
Anthropogenic nitrogen (N) deposition has accelerated terrestrial N cycling at regional and global scales, causing nutrient imbalance in many natural and semi-natural ecosystems. How added N affects ecosystems where N is already abundant, and how plants acclimate to chronic N deposition in such circumstances, remains poorly understood. Dr. ... -
2018-08-17Research Progress on Community EcologyDisentangling ecological processes that influence community assembly and species diversity across spatial scales remains a major goal of community ecology .Figure .

Disentangling ecological processes that influence community assembly and species diversity across spatial scales remains a major goal of community ecology. Community assembly processes influence spatial patterns of species diversity through their interactions with plant functional traits. Hence, quantifying spatial patterns of functional tr...
