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

2010-06-28New Advances on Negative Responses to Long-term N Deposition MadeIn 0-15 cm soil layer,it showed a clear tendency of reduction of Collembola community in N-treated plots than in control plots. For example,the density of Isotomiella minor was reduced significantly by 80% in N-treated plots(17 000 ind m-3)in 0-5 cm soil layer compared with control plots(85 600 ind m-3).It was also found that Shannon-Wiener inde... Elevated nitrogen (N) deposition, one of the most important problems on global changes, has shown to have a variety of effects on terrestrial systems in temperate Europe and North American. Currently, many results about the reactions of ecosystem to N deposition, including biodiversity, primary productivity, nutrient cycling, N transformation an...Read More
