Silicon limitation on primary production and its destiny in Jiaozhou Bay,China V:Silicon deficit process

Silicon is a necessary nutrient for diatoms, silicon uptake in diatom reproduction decreased sea- water silicon content. This paper clarified the characteristics of silicon transferring in the sea, which plays an important role in phytoplankton growth, zooplankton graze and marine ecosystem. Analysis revealed that silicate is supplied by terrestrial sources, through plankton uptake, death, and eventually deposits to the sea bottom, and cannot diffuse upward. This is a general silicon deficit process. Many global marine waters showed the same silicon transfer route: land→silicon biogeochemical process→sea bottom. River flow brings abundant silicate into marine waters, silicate concentration in the waters decreased in the distance away from the river estuaries. In discussion of silicon characteristics and its transfer route, it was considered that the main factor controlling the mechanism of diatom and non-diatom red tides occurrence is silicon, and the changes in silicon source. Human activities, such as sea-route cutting by building embankment and dam, and silicon supplement by the sea, such as sandstorm, rainstorm and storm tide, have largely impaired the earth ecosystem and hugely threatened the human existence. It is suggested in this paper that man should resume the original face of the Si input into the sea to keep natural ecosystem in sustainable pattern.

Research and Practice on the College English Listening and Speaking Teaching

With the growing trend of globalization, English learning enthusiasm has increased in the land of China. Universities are no exception, the state of college English teaching invests labor, material and time, which is enormous. However, far more than the input and output did not reach the desired level that mainly reflected in the students＇ listening and speaking ability that is generally poor. The traditional thing on teaching students English reading, writing and translation capabilities are resulting in a ＂dumb＂ English, ＂deaf＇ English everywhere. In an increasingly integrated world economy today, English is a communication tool; the user in community uses the ability to meet a higher requirement. With reading, writing and translation capabilities, listening, and speaking skills for university graduates, they can have the ability to survive in nature. In the communication, listening and hearing are instant, they did not understand, and cannot say; in a word the communication is doomed to fail. Reading and speaking can be delayed when people cannot read nor write, they can look into the dictionary, ask others with slow discretion.

Dengue: what it is and why there is more

In 2014, China experienced the worst outbreak of dengue fever in the last decade with over 40,000 dengue cases including six deaths by the end of October. As one of the ＂neglected＂ tropical diseases, dengue is affecting substantially increasing number of people and proportion of global population due to factors including globalization, human settlement, and possibly climate change. Here, the authors summarized the most recent data about dengue outbreaks in China and reviewed the global trend of dengue epidemiology. Future directions for dengue surveillance, control and prevention are also introduced.

Invasive house geckos （hemidactylus spp.）： their current, potential and future distribution

In this study, we identified the current distribution of five globally distributed invasive Hemidactylus species and predicted their potential and future distribution using species distribution models based on climate and elevation data. These species included H. brookii, H. frenatus, H. garnotii, FI. mabouia, and H. turcicus. We show that many regions with tropical and Mediterranean climates are suitable for most of these species. However, their current and potential distributions sug- gest that climate is not the only limiting factor. We hypothesize that climatic conditions may affect competition and other interactions resulting in a segregated distribution of the studied Hemidactylus species. As an effect of global climate change it is likely that H. brookiiwill expand its range to areas that are currently colonized by H. mabouia and/or H. frenatus, while H. turcicus is likely to expand its range to areas that are not yet invaded by any Hemidactylus species. The role of species interactions in the range expansion of these five Hemidactylus species still remains poorly understood, but could be of major importance in understanding and managing these invasive species.

Analysis of spatial distribution and multi-year trend of the remotely sensed soil moisture on the Tibetan Plateau

Long-term highly accurate surface soil moisture data of TP(Tibetan Plateau)are important to the research of Asian monsoon and global atmospheric circulation.However,due to the sparse in-situ networks,the lack of soil moisture observations has seriously hindered the progress of climate change researches of TP.Based on the Dual-Channel soil moisture retrieval algorithm and the satellite observation data of AMSR-E(Advanced Microwave Scanning Radiometer for EOS),we have produced the surface soil moisture data of TP from 2003 to 2010 and analyzed the seasonal characteristic of the soil moisture spatial distribution and its multi-year changing trend in area of TP.Compared to the in-situ observations,the accuracy of the soil moisture retrieved by the proposed algorithm is evaluated.The evaluation result shows that the new soil moisture product has a better accuracy in the TP region than the official product of AMSR-E.The spatial distribution of the annual mean values of soil moisture and the seasonal variations of the monthly-averaged soil moisture are analyzed.The results show that the soil moisture variations in space and time are consistent with the precipitation distribution and the water vapor transmission path in TP.Based on the new soil moisture product,we also analyzed the spatial distribution of the changing trend of multi-year soil moisture in TP.From the comparisons with the precipitation changing trend obtained from the meteorological observation sites in TP,we found that the spatial pattern of the changing trend of soil moisture coincides with the precipitation as a whole.

Tameike Reservoirs as Agricultural Heritage: From the Case Study of Kunisaki Peninsula in Oita, Japan

This paper looks at the agricultural heritage potential of the tameike reservoirs in Japan,through a case study of the Kunisaki Peninsula,which was recognized as a Globally Important Agricultural Heritage System （GIAHS） in May,2013.The ＂tameike＂ in this area are small scale ponds storing spring water or water flowing through the short and rapid rivers of the area.Tameike construction in Kunisaki is found to be closely associated with the spread of wet rice cultivation and forestry.Most existing reservoirs were built during the Edo Period （1603-1867）,and were managed through traditional farming knowhow till the postwar period.However,rapid decline in the use and ecosystem functions of these reservoirs ensued from the years of economic development,and at present,total number of these reservoirs has fallen to nearly one-third,compared to the pre-Meiji time.The GIAHS initiative is trying to reevaluate the ecosystem functions and knowledge systems associated with these reservoirs and link them to rural revitalization efforts.This article is based on both literature survey and field based research with regional coordinators,and comes to the conclusion that proper management of these reservoirs can successfully reinvigorate a culture of resource circulation,that defined the agri-heritage of Kunisaki area in historical times.

Evaluation of farmland losses from sea level rise and storm surges in the Pearl River Delta region under global climate change

The Pearl River Delta on China's coast is a region that is seriously threatened by sea level rise and storm surges induced by global climate change, which causes flooding of large areas of farmland and huge agricultural losses. Based on relevant research and experience, a loss evaluation model of farmland yield caused by sea level rise and storm surges was established. In this model, the area of submerged farmland, area of crops, and per unit yield of every type of crop were considered, but the impact of wind, flooding time, changes in land use and plant structure were not considered for long-term prediction. Taking the Pearl River Delta region in Guangdong as the study area, we estimated and analyzed the spatial distribution and loss of farmlands for different scenarios in the years 2030, 2050, and 2100, using a digital elevation model, land-use data, local crop structure, rotation patterns, and yield loss ratios for different submerged heights obtained from field survey and questionnaires. The results show that the proportion of submerged farmlands and losses of agricultural production in the Pearl River Delta region will increase gradually from 2030 to 2100. Yangjiang, Foshan, and Dongguan show obvious increases in submerged farmlands, while Guangzhou and Zhuhai show slow increases. In agricultural losses, vegetables would sustain the largest loss of production, followed by rice and peanuts. The greatest loss of rice crops would occur in Jiangmen, and the loss of vegetable crops would be high in Shanwei and Jiangmen. Although losses of peanut crops are generally lower, Jiangmen, Guangzhou, and Shanwei would experience relatively high losses. Finally, some measures to defend against storm surges are suggested, such as building sea walls and gates in Jiangmen, Huizhou, and Shanwei, enforcing ecological protection to reduce destruction from storm surges, and strengthening disaster warning systems.
