2010-09-16SCBG Achieve New Progress in the Research of Mangrove Restoration and Urban Wetland ChangesSuch changes in the distribution of mangroves and wetland have a serious influence on the mangrove communities and aquatic environment of Shenzhen Bay Dr. The Fengtang River Mangrove Restoration Demonstration Area has been almost completed and has already received high appreciation from the local government and the public The project was support... Shenzhen Bay is located in two large, modern cities (Shenzhen and Hong Kong) on the east coast of the Pearl River Estuary. Being a stopover station and habitat of migratory birds for the north-south flyway in Eastern Hemisphere, the mangrove ecosystem in the Shenzhen Bay has extremely important ecosystem service functions. By analyzing five-phas...Read More -
2010-09-13Floral Ontogeny of Annonaceae: Evidence for High Variability in Floral FormAnnonaceae is a remarkably diverse family of Magnoliales. Ronse De Craene of Royal Botanic Garden Edinburgh,Britain investigated the floral development of 15 species with the scanning electron microscope to understand the basis for evolutionary change in flowers of Annonaceae. They also found an increase of stamen number is correlated with their... Annonaceae is a remarkably diverse family of Magnoliales.

2010-09-02Ancient Genome Duplications During the Evolution of Kiwifruit (Actinidia) and Related EricalesPaleopolyploidy refers to ancient genome duplications which occurred at least several million years ago. Due to functional redundancy,genes are rapidly silenced and/or lost from the duplicated genomes. The most recent event is consistent with previous cytological work on kiwi while the older event is shared by the common ancestor of Camellia and... Paleopolyploidy refers to ancient genome duplications which occurred at least several million years ago. The genome doubling event could either be an autopolyploidy or an allopolyploidy. Due to functional redundancy, genes are rapidly silenced and/or lost from the duplicated genomes. Most paleopolyploids, through evolutionary time, have lost the...Read More -

2010-07-28Mussaenda Pubescens (Rubiaceae): A Case on the Evolution of Dioecy from Stigma-height DimorphismHerkogamy is a common strategy employed by hermaphroditic angiosperms to reduce self interference within flowers. Stigma-height dimorphism is a less well-known reciprocal herkogamy. In species with stigma-height dimorphism,individuals within a population have two floral-morphs and flowers of different morphs differ significantly in style length ...

2010-07-22Research Progress on Mutualism of Figs and Fig WaspsFigs and their pollinating wasps constitute one of the classic examples of pollination mutualism and appear to present one of the best cases of co-evolution known. Figs are completely dependent on fig wasp for pollen dispersal and the production of viable seeds. So the seeds are more effective to gene flow among populations for dioecous figs We ... Figs (Ficus species, Moraceae) are defined by a unique enclosed inflorescence, the syconium, which are also the arena for interactions with fig wasps. Figs and their pollinating wasps constitute one of the classic examples of pollination mutualism and appear to present one of the best cases of co-evolution known. Figs are completely dependent on...Read More
