2012-05-10The Study Progress of Pollination Biology of Guihaiothamnus acaulis (Rubiaceae), a Critically Endangered Species in ChinaFlower is the sexual reproductive organ of flowering plants. In the traditional theory of pollination biology,pollinators determine the evolution of flower traits. All of these characters are thought to be associated with the butterfly pollination syndrome. The loss of butterflies might result in the reduction of nectar,and more energy was saved... Flower is the sexual reproductive organ of flowering plants. In the traditional theory of pollination biology, pollinators determine the evolution of flower traits. That is to say, suites of floral characters (including shape, color, scent, and reward), which are known as pollination syndromes, reflect the response to the selective pressure exer...Read More -

2012-04-17Rediscovered Phylogenetics of Wenchengia (Lamiaceae)Chow was established on the basis of two collections(four sheets)from the 1930s.The genus is characterized by alternate leaves,racemose inflorescences,and a unique type of nutlet attachment described as vascular funicles and slender stalks,and was assigned to a monotypic subfamily,Wenchengioideae,based on its morphological uniqueness in Lamiacea... Wenchengia C. Y. Wu & S. Chow, a rare and endangered monotypic genus of Lamiaceae, is endemic to the island of Hainan. The genus and its sole member species, W. alternifolia C. Y. Wu & S. Chow was established on the basis of two collections (four sheets) from the 1930s. The genus is characterized by alternate leaves, racemose inflorescences, and...Read More -
2012-02-24The study progress of coevolution of fig and fig wasp in South China Botanical Garden,Moraceae).They are shaped like a hollow ball,lined on their inner surface by numerous tiny female flowers. Pollination is carried out by host-specific fig wasps(Agaonidae).Female pollinators enter the figs through a narrow entrance gate. Most NPFW oviposit from the outside of figs,making peripherally-located pollinator larvae more prone to atta... Figs are the inflorescences of fig trees (Ficus spp. Moraceae). They are shaped like a hollow ball, lined on their inner surface by numerous tiny female flowers. Pollination is carried out by host-specific fig wasps (Agaonidae). Female pollinators enter the figs through a narrow entrance gate. They lay their eggs into the ovules, via the stigmas...Read More -
2012-01-13Effects of Plant Functional Group Removal on Microbial Substrate Metabolic Function and Soil Respiration in Subtropical Eucalyptus PlantationsSince aboveground communities and belowground communities are intimately linked and these linkages greatly affect ecosystem properties,removal of plant functional groups from aboveground communities will exert a great impact on belowground communities. Based on the previous works that found plant functional group removal greatly altered soil mic...
