Community structure and controlled factor of attached green algae on the Porphyra yezoensis aquaculture rafts in the Subei Shoal, China

This study analyzes the community structure, the quantity changes of the algae and the effect of important environmental factors and estimates the total biomass of the attached green algae in the survey areas. The study uses data from surveys of the attached green algae on the Porphyra yezoensis aquaculture rafts and data regarding the environmental factors from October 2010 to April 2011 in the Subei Shoal. The attached green algae on the rafts included Ulva prolifera, Capsosiphon groenlandicus, U. linza, U. intestinalis, U. clathrata, and U. cornpressa. The biomass changes of the attached green algae exhibited an inverted parabola： the biomass was the highest （14 898 t） in April, and was the second highest （2 034 t） in November; it was lowest in February （only 729 t） and increased sharply from March to April. The species diversity differed significantly among the seasons. In September and October, when the P. yezoensis aquaculture rafts were initially set up, the attached green algae had a high biodiversity, while from December to the next February, a variety of green algae species coexisted on the rafts, although the biomass was low, and from March to April, as the biomass increased sharply, the species diversity dropped to the minimum. During this time, C. groenlandicus was apparently dominant with the maximum biomass proportion up to 80%, while the U. prolifera proportion increased exponentially to 20% to 40%. The water temperature had a direct regulating effect on the biomass and the species succession of the attached green algae. The estimation of the community dynamics and the biomass of the green algae provided the evidence needed to track the origin of the large-scale green tide in the southern Yellow Sea.

Long-term rice-rice-green manure rotation changing the microbial communities in typical red paddy soil in South China

On the basis of a long-term（30 years） field experiment that involved four rotation systems, rice-rice-winter fallow（RRF）, rice-rice-ryegrass（RRG）, rice-rice-rape（RRP）, and rice-rice-milk vetch（RRV）, this study described the effects of green manure on the microbial communities in the red paddy soils using 454 pyrosequencing for the 16 S r RNA gene. The Chao1 richness and non-parametric Shannon＇s index increased in all soil samples that received green manure treatments. The communities＇ structures with the green manure applications were significantly dissimilar from that under the winter fallow. Using Metastats tests, many genera in the RRG, RRP and RRV soils were significantly different from those in the RRF soil, including a number of genera that functioned in the nitrogen and sulfur cycles. Analyses of the genera with these functions revealed the shifts in microbial ecosystem functions after long-term green manuring. Changes in the microbial communities increased the ammonium supply and decreased the soil acidification in green-manure-amended soils. Together, these data suggested powerful effects of green manure on both the microbial communities and the biogeochemical cycle driven by the shifts in bacterial functional groups.

Green manuring facilitates bacterial community dispersal across different compartments of subsequent tobacco

Green manure–crop rotation is a sustainable approach to protect crops against diseases and improve yield.However,the mechanism by which green manuring manipulates the crop-associated microbial community remains to be elucidated.In this study,we explored the horizontal processes of bacterial communities in different compartments of the soil–root interface(bulk soil,rhizosphere soil,rhizoplane and endosphere)of tobacco by performing a field experiment including four rotation practices,namely,tobacco rotated with smooth vetch,ryegrass,radish,and winter fallow(without green manure).Results showed that the co-occurrence networks constructed by adjacent compartments of the soil–root interface with green manuring had more edges than without green manuring,indicating dramatic microbial interactions.Green manuring increased the dispersal-niche continuum index between bulk soil and other compartments,indicating that it facilitated the horizontal dispersal of microbes.For the different green manuring practices,the neutral community model explained 24.6–27.6%of detection frequency for bacteria,and at least one compartment under each practice had a normalized stochasticity ratio higher than the 50%boundary point,suggesting that the deterministic and stochastic processes jointly shaped the tobacco microbiome.In conclusion,green manuring generally facilitates bacterial community dispersal across different compartments and enhances potential interactions among adjacent compartments.This study provides empirical evidence for understanding the microbiome assembly under green manure–crop rotation.

Potentials of community-based tourism in transformations towards green economies after the 2008 Wenchuan earthquake in West China

This study investigates the contrasting sceneries of community-based tourism after the 2008 Wenchuan earthquake and focuses on the potentials of tourism in transformations towards green economies. How are tourism and environment linked in a sustainable relationship? And how can potentials of community-based tourism be directed in transformations towards green economies? A qualitative research design is used to examine contrasting sceneries and specific green elements of community-based tourism in a Qiang people's fortress village in Mao County, Sichuan Province, West China and further discuss how tourism can be compatible with human wellbeing through demonstrating a commitment to sustainable development. The study argues that potential economic, social and environmental costs of tourism need to be considered when evaluating the loss of community benefits toward sustainability. The green elements suggest the potential of community-based tourism in transformations towards green economies, involving green agricultural, green building, and green energy, green governance, green service and green consumption. This study will contribute to the debate about the relationship between tourism and environment sustainability in the green economies, as well as the critique of what can be learned for community development from green tourism in mountainous regions after the inevitable natural disasters.

REFERENCE COMMUNITY: ADAPTING NATIVE PLANTS TO NORTH AMERICAN GREEN ROOFS

The North American design community typically regards green roofs as inhospitable environments for native plants due to the infrastructure’s characteristic thin soils,low organic matter,temperature fluctuations,and wind exposure.Consequently,green roofs are often planted with an industry-standard palette of non-native Sedum and Phedimus species that are adept at withstanding stress,but lack biodiversity and visual interest,and offer little food or shelter to native birds and insects.Regionally specific reference plant communities that thrive in similarly harsh growing conditions can positively influence green roof design throughout North America,and consequently provide ecosystem services,contribute to habitat conservation,and increase human exposure to the beauty and benefits of native plants.
