2017-11-29New progress was made in the study of species diversity and co-occurrence network of soil microbes in the south subtropical forestPrecipitation regime change presents serious ecological consequences in diverse ecosystems , particularly forests .The richness and abundance of Sordariomycetes were reduced , while the abundance of ectomycorrhizal fungi was elevated by MAPS . The co-occurrence network of fungal OTUs ( fungal network ) was also changed more than the bacterial ne... Precipitation regime change presents serious ecological consequences in diverse ecosystems, particularly forests. Soil microorganisms can have great feedback to the carbon stock of subtropical forest, but the sensitivity of microbial community in multiple aspects to the precipitation change is still not sufficiently understood.Read More

2017-11-27The mechanism behind forest decline and death in the northern hemisphere recently being clarifiedInsects , diseases , fire and drought and other disturbances associated with global climate change contribute to forest decline and mortality in many parts of the world .Forest decline and mortality related to drought or insect outbreaks have been observed in North American aspen forests .In addition , data suggest that insect outbreaks could be... Insects, diseases, fire and drought and other disturbances associated with global climate change contribute to forest decline and mortality in many parts of the world. Forest decline and mortality related to drought or insect outbreaks have been observed in North American aspen forests. However, little research has been done to partition and est...Read More -
2017-11-20Responses of Tree Transpiration and Growth to Seasonal Rainfall Redistribution in a Subtropical Evergreen Broad-Leaved ForestPrecipitation changes such as more frequent drought and altered precipitation seasonality may impose substantial impacts on the structure and functioning of forest ecosystems .Three precipitation treatments were administered including a drier dry season and wetter wet season treatment ( DD ) , an extended dry season and wetter wet season treatme...Read More
Precipitation changes such as more frequent drought and altered precipitation seasonality may impose substantial impacts on the structure and functioning of forest ecosystems. A better understanding of tree responses to precipitation changes can provide fundamental information for the conservation and management of forests under future clim... -
2017-11-17Research showing a two-layer mode of reticulate diversification in kiwifruit plantsReticulate speciation caused by interspecific hybridization is now recognized as an important mechanism in the creation of biological diversity .However , depicting the patterns of phylogenetic networks for lineages that have undergone interspecific gene flow is challenging .On the basis of the elucidated hybridization relationships , the resear... Reticulate speciation caused by interspecific hybridization is now recognized as an important mechanism in the creation of biological diversity. However, depicting the patterns of phylogenetic networks for lineages that have undergone interspecific gene flow is challenging.Read More

2017-11-16Past climatic change as a driver of plant diversification in the karst ecosystems from southern ChinaKarst ecosystems in southern China are species-rich and have high levels of endemism , yet little is known regarding the evolutionary processes responsible for the origin and diversification of karst biodiversity .A typical karst plant in southern China . They found that speciation was positively associated with changes in past temperatures and ...Read More
Karst ecosystems in southern China are species-rich and have high levels of endemism, yet little is known regarding the evolutionary processes responsible for the origin and diversification of karst biodiversity. Dr. Hanghui Kong et al. from the Plant Genetic Resources and Evolution Lab, South China Botanical Garden, reconstructed the phylo... -

2017-09-30Remote Sensing of Environment: The Microwave Temperature Vegetation Drought Index (MTVDI) for long-term drought assessmentSatellite-based drought indices have been proved to be effective and convenient in detecting drought conditions at regional and global scales .Microwave sensors can overcome the shortages of visible/near infrared/thermal remote sensing and show to be another important approach for drought monitoring due to its all-weather working advantages .But...Read More
Satellite-based drought indices have been proved to be effective and convenient in detecting drought conditions at regional and global scales. However, most current drought indices are based on the visible/near infrared/thermal remote sensing,which might be influenced greatly by cloud, atmospheric water content and rain-fall. Microwave sens...
