Soil Conservation Measures in Rainfed Olive Orchards in South-Eastern Spain:Impacts of Plant Strips on Soil Water Dynamics

Sloping and mountainous olive production systems are widespread,occupying large parts of the Mediterranean landscape prone to water erosion.Soil erosion,runoff,and soil water content patterns over a three-year period were monitored in erosion plots on a mountainside with rainfed olive (Olea europaea cv.Picual) trees under:1) non-tillage with barley strips of 4 m width (BS);2) non-tillage with native vegetation strips of 4 m width (NVS);and 3) non-tillage without plant strips (NT).The erosion plots,located in Lanjaron (Granada,south-eastern Spain),on a 30% slope,were 192 m~2 in area.For assessing soil water dynamics in real-time and near-continuons soil water content measurements,multiseusor capacitance probes were installed in the middle of plant strips and beneath the olive tree at five soil depths (10,20,30,50,and 100 cm).The highest erosion and runoff rates were measured under NT,with a mean of 17.3 Mg ha~(-1) year~(-1) and 140.0 mm year~(-1),respectively,over the entire study period.The BS and NVS with respect to the NT reduced erosion by 71% and 59% and runoff by 95% and 94%,respectively.In general,greater available soil water content was found under BS than NVS and NT,especially beneath the olive tree canopies.These results supported the recommendation of non-tillage with barley strips in order to reduce erosion and to preserve soil water for trees in traditional mountainous olive-producing areas,where orchards cover vast tracts of land.
Combining Ridge with No-Tillage in Lowland Rice-Based Cropping System:Long-Term Effect on Soil and Rice Yield

A tillage method of combining ridge with no-tillage (RNT) was employed in lowland rice-based cropping system to study the long-term effects of RNT on soil profile pattern,soil water stable aggregate distribution,nutrients stratification and yields of rice and post-rice crops.After flooded paddy field (FPF) was practiced with RNT for a long time,soil profile changed from G to A-P-G,and horizon G was shifted to a deeper position in the profile.Also the proportion of macroaggregate (＞ 2 mm) increased,whereas the proportion of silt and clay (＜ 0.053 mm) decreased under RNT,indicating a better soil structure that will prevent erosion.RNT helped to control leaching and significantly improved total N,P,K and organic matter in soil.The highest crop yields were found under RNT system every year,and total crop yields were higher under conventional paddy-upland rotation tillage (CR) than under FPF,except in 2003 and 2006 when serious drought occurred.RNT was proven to be a better tillage method for lowland rice-based cropping system.
Calcareous Sodic Soil Reclamation as Affected by Corn Stalk Application and Incubation:A Laboratory Study

A laboratory lysimeter experiment was conducted to investigate the effects of forage corn (Zea mays L.) stalk application on the CO_2 concentration in soil air and calcareous sodic soil reclamation.The experimental treatments tested were soil exchangeable sodium percentage (ESP) levels of 1,11,and 19,added corn stalk contents of 0 to 36 g kg~(-1),and incubation durations of 30 and 60 days.The experimental results indicated that corn stalk application and incubation significantly increased CO_2 partial pressure in soil profile and lowered pH value in soil solution,subsequently increased native CaCO_3 mineral dissolution and electrolyte concentration of soil solution,and finally significantly contributed to reduction on soil sodicity level.The reclamation efficiency of calcareous sodic soils increased with the added corn stalk.When corn stalks were added at the rates of 22 and 34 g kg~(-1) into the soil with initial ESP of 19,its ESP value was decreased by 56% and 78%,respectively,after incubation of 60 days and the leaching of 6.5 pore volumes (about 48 L of percolation water) with distilled water.Therefore,crop stalk application and incubation could be used as a choice to reclaim moderate calcareous sodic soils or as a supplement of phytoremediation to improve reclamation efficiency.
Spatial Variability of Soil Organic Carbon in a Watershed on the Loess Plateau

Soil organic carbon (SOC) has great impacts on global warming,land degradation and food security.Classic statistical and geostatistical methods were used to characterize and compare the spatial heterogeneity of SOC and related factors,such as topography,soil type and land use,in the Liudaogou watershed on the Loess Plateau of North China.SOC concentrations followed a log-normal distribution with an arithmetic and geometric means of 23.4 and 21.3 g kg~(-1),respectively,were moderately variable (CV=75.9%),and demonstrated a moderate spatial dependence according to the nugget ratio (34.7%).The experimental variogram of SOC was best-fitted by a spherical model,after the spatial outliers had been detected and subsequently eliminated.Lower SOC concentrations were associated with higher elevations.Warp soils and farmland had the highest SOC concentrations,while aeolian sand soil and shrublands had the lowest SOC values.The geostatistical characteristics of SOC for the different soil and land use types were different.These patterns were closely related to the spatial structure of topography,and soil and land use types.

aBiological properties of neonatal mouse olfactory ensheathing cells purified by differential attachment, cytosine arabinoside, and mitogen stimulation

BACKGROUND: Differential attachment, chemicals, and immunoaffinify absorption are frequently used to purify olfactory ensheathing cells (OECs). Although purity is high (> 90%), the complex process, high cost, decreased cell activity, and cell loss limit their application.OBJECTIVE: To purify OECs using differential attachment, cytosine arabinoside (Ara-C), and mitogen stimulation, and to analyze the biological characteristics of OECs.DESIGN, TIME AND SETTING: Molecular biology experiment of cell morphology and immunocytochemistry. The study was performed at the Institute of Neuroscience, Kunming Medical College between January 2005 and January 2007.MATERIALS: N2 was purchased from Gibico, USA; basic fibroblast growth factor (bFGF) from Invitrogen, USA; PCR master mix kit from Fermentas, USA; nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) from Santa Cruz Biotechnology, USA; OEC specific immunological marker NGF receptor (p75NGFR) from ABCAM, UK; immunological markers of oligodendrocyte and Schwann cells, cyclic nucleotide 3' phosphohydrolase (CNPase), from NeoMarkers, USA; inverted fluorescence microscope from Leica, Germany.METHODS: OECs were isolated from olfactory bulbs of mice provided by Institute of Cancer Research (ICR mice) at postnatal 1-2 days, and purified by differential attachment, Ara-C inhibition (5 mg/L), and 10 μg/L mitogen bFGF and 0.5% N_2 stimulation.MAIN OUTCOME MEASURES: OEC growth was observed under inverted microscope; cell purity, as well as expression of NGF and BDNF, was determined by means of immunocytochemistry; expression of β-NGF, BDNF, NT-3, platelet-derived growth factor-B (PDGF-B), bFGF, epidermal growth factor (EGF), NGF receptor TrkA, BDNF receptor TrkB, and NT-4 mRNA were detected by RT-PCR.RESULTS: The majority of in vitro cultured OECs was bipolar or tripolar, and purity was estimated to be > 92.4%. Immunocytochemistry demonstrated expression of p75NGFR, NGF, BDNF and CNPase. The RT-PCR results suggested that OECs expressed β-NGF, BDNF, NT-3, PDGF-B, bFGF, EGF, TrKA, and TrkB mRNA.CONCLUSION: Results demonstrated that purity of OECs was high, and that OECs expressed CNPase proteins and produced neurotrophic factors.

Biofilm structure and its influence on clogging in drip irrigation emitters distributing reclaimed wastewater

Using reclaimed wastewater for crop irrigation is a practical alternative to discharge wastewater treatment plant effluents into surface waters.However,biofouling has been identified as a major contributor to emitter clogging in drip irrigation systems distributing reclaimed wastewater.Little is known about the biofilm structure and its influence on clogging in the drip emitter flow path.This study was first to investigate the microbial characteristics of mature biofilms present in the emitters and the effect of flow path structures on the biofilm microbial communities.The analysis of biofilm matrix structure using a scanning electron microscopy (SEM) revealed that particles in the matrix of the biofilm coupled extracellular polysaccharides (EPS) and formed sediment in the emitter flow path.Analysis of biofilm mass including protein,polysaccharide and phospholipid fatty acids (PLFAs) showed that emitter flow path style influenced biofilm community structure and diversity.The correlations of biofilm biomass and discharge reduction after 360 h irrigation were computed and suggest that PFLAs provide the best correlation coefficient.Comparatively,the emitter with the unsymmetrical dentate structure and shorter flow path (Emitter C) had the best anti-clogging capability.By optimizing the dentate structure,the internal flow pattern within the flow path could be enhanced as an important method to control the biofilm within emitter flow path.This study established electron microscope techniques and biochemical microbial analysis methods that may provide a framework for future emitter biofilm studies.

The progress of catalytic technologies in water purification:a review

Catalytic technologies have been paid increasing attention in refractory pollutants abatement due to its practical and potential values in water purification.As effective and efficient approaches for water purification,Fenton's reagent,ozonation,electrochemical and photocatalytic methods have been widely studied and applied in different aspects and have been reviewed by several papers.In recent years,some novel catalytic processes based on above processes have been developed for enhancing the efficiency of removing the organics form water.This reviews emphasize on the recent development of heterogeneous catalytic ozonation,electrocatalysis in respect of novel electrodes and electro-Fenton method (EF),photoelectrocatalysis process (PEC) and photoelectron-Fenton (PEF) in water purification.It is also an attempt to propose general ideas about mechanism and principle enhancing the catalytic efficiency for degradation and mineralization of organics in water.
Dehydrolutein: a metabolically derived carotenoid never observed in raptors

Carotenoids are fat-soluble pigments synthesised by photosynthetic organisms (Brush, 1990). Conversely, animals are incapable of synthesizing carotenoids de novo, and they must obtain them through their diet. However, some animal species are able to make some alterations to the basic chemical structure, converting ingested carotenoids into more oxidized and differently coloured forms (Schiedt, 1998).
An Integrated Analysis of Dry-Wet Variability in Western China for the Last 4-5 Centuries

The dry-wet variability in western China and its spatiotemporal structure during the last 4-5 centuries was examined using 24 climate proxies from sediments,ice cores,historical documents,and tree rings.Spatial patterns and temporal evolutions of dryness and wetness were not only extracted from the proxy data using rotated empirical orthogonal function (REOF) analysis for the last 4 centuries,but also for instrumental data in the last 40 years.The leading five REOF modes indicate that 5 dry-wet variation centers exist in western China.Moreover,long-term variability in dryness and wetness is seen on long (centennial) to short (inter-decadal) timescales.An out-of-phase relationship for the inter-decadal variation was observed between the Hetao-upper Yangtze River region and north Xinjiang,indicating influences on dry-wet variations of the East Asian summer monsoon and the westerly winds over the two regions,respectively.A particularly long dry spell was found in the central Tibetan Plateau in the 19th century.A predominance of wet decades in the last 4 centuries was found in the arid and Hetao regions.Three regional dry-wet series with annual resolution in north Xinjiang,the upper Yellow River valley,and the Hetao area were constructed for analyses of the last 500 years.Dry-wet oscillations with periodicities of 16,50,and 150 years in north Xinjiang,50 years in the upper Yellow River valley,and 70-80 years in the Hetao region were identified by wavelet analysis.In general,these periods correspond to large-scale oscillations found in the climate system,are mainly related to ocean-atmosphere interaction.
Simulating Tropical Instability Waves in the Equatorial Eastern Pacific with a Coupled General Circulation Model

Satellite observations of SSTs have revealed the existence of unstable waves in the equatorial eastern Pacific and Atlantic oceans. These waves have a 20-40-day periodicity with westward phase speeds of 0.4-0.6 m s~(-1) and wavelengths of 1000-2000 km during boreal summer and fall.They are generally called tropical instability waves (TIWs).This study investigates TIWs simulated by a high-resolution coupled atmosphere-ocean general circulation model (AOGCM).The horizontal resolution of the model is 120 km in the atmosphere,and 30 km longitude by 20 km latitude in the ocean.Model simulations show good agreement with the observed main features associated with TIWs.The results of energetics analysis reveal that barotropic energy conversion is responsible for providing the main energy source for TIWs by extracting energy from the meridional shear of the climatological-mean equatorial currents in the mixed layer.This deeper and northward-extended wave activity appears to gain its energy through baroclinic conversion via buoyancy work,which further contributes to the asymmetric distribution of TIWs.It is estimated that the strong cooling effect induced by equatorial upwelling is partially (～30%-40%)offset by the equatorward heat flux due to TIWs in the eastern tropical Pacific during the seasons when TIWs are active.The atmospheric mixed layer just above the sea surface responds to the waves with enhanced or reduced vertical mixing.Furthermore,the changes in turbulent mixing feed back to sea surface evaporation,favoring the westward propagation of TIWs.The atmosphere to the south of the Equator also responds to TIWs in a similar way,although TIWs are much weaker south of the Equator.
Improving Multimodel Weather Forecast of Monsoon Rain Over China Using FSU Superensemble

In this paper we present the current capabilities for numerical weather prediction of precipitation over China using a suite of ten multimodels and our superensemble based forecasts.Our suite of models includes the operational suite selected by NCARs TIGGE archives for the THORPEX Program.These are:ECMWF,UKMO,JMA,NCEP,CMA,CMC,BOM,MF,KMA and the CPTEC models.The superensemble strategy includes a training and a forecasts phase,for these the periods chosen for this study include the months February through September for the years 2007 and 2008.This paper addresses precipitation forecasts for the mcdium range i.e.Days 1 to 3 and extending out to Day 10 of forecasts using this suite of global models.For training and forecasts validations we have made use of an advanced TRMM satellite based rainfall product.We make use of standard metrics for forecast validations that include the RMS errors,spatial correlations and the equitable threat scores.The results of skill forecasts of precipitation clearly demonstrate that it is possible to obtain higher skills for precipitation forecasts for Days 1 through 3 of forecasts from the use of the multimodel superensemble as compared to the best model of this suite.Between Days 4 to 10 it is possible to have very high skills from the multimodel superensemble for the RMS error of precipitation.Those skills are shown for a global belt and especially over China.Phenomenologically this product was also found very useful for precipitation forecasts for the Onset of the South China Sea monsoon,the life cycle of the mci-yu rains and post typhoon landfall heavy rains and flood events.The higher skills of the multimodel superensemble make it a very useful product for such real time events.
Types and spatial combinations of Danxia Iandform of Fangyan in Zhejiang Province

The prominent types of Danxia landform in Fangyan include enclosed valleys,mesas, peaks, stone columns and grooves etc. Their spatial combinations have regular con-figurations along the northwest-southeast direction: typical grooves and caves are located in the northwestern Wufengshuyuan mainly; abundant fresh collapsed stones may be observed in central Jimingfeng and Taohuafeng; stone drums and stone columns are in the southeast-ern Shiguliao particularly; enclosed valleys are encircling joints of peaks and plains from three directions east, west, and south. Their spatial combinations reflect that the developments of Danxia landform have undergone stages of geomorphic cyclical erosion in the form of weathering, collapse, transportation, sedimentation and other processes, together with the "sculpture" of external forces mainly as tectonic uplift. The picturesque Danxia landform be-gan its formation at that point. Danxia landform developed mainly in the strata of Fangyan Formation (K1f) caused by the alluvial fan-braided river phase of anterior fan in the late period of the Early Cretaceous. Regular patterns of weathering of stones and features of braided alluvial phase sediments may be verified by the analysis of three groups of experimental data.Danxia landform of Fangyan is a unique representative of the "adolescent" development type in the application of the World Natural Heritages status in China, by virtue of its outstanding universal aesthetic and scientific value.
Land use optimization at small watershed scale on the Loess Plateau

At present, land use optimization at small watershed scale is the key measure to control soil erosion, restore the eco-environment and improve the farmers' living standard on the Loess Plateau, China. Based on the land use survey maps of 1966, 1988, 1997, 2003 and the digital topographic map of 1984 in Yangou watershed, and assisted by spatial techniques of GIS, the basic characteristics and driving forces of land use change in Yangou watershed are analyzed. According to the summarization of land-use optimization characteristics since 1997, and with the help of continuous monitoring data for years and farmer investigation data,this paper appraises eco-environmental benefits, economic benefits and sustainability of Yangou watershed. We have used sediment reduction benefits, coverage ratio of permanent vegetation, per capita food production and per capita income of farmers as indices. The re-sults show that Yangou watershed project has successfully controlled the soil and water loss and the farmers' living standard has been improved markedly by reasonable adjustment to land use structure. The benefit of sediment reduction is higher than 80% and the coverage ratio of permanent vegetation reaches 61.03%. In 2006, the per capita income increased by 1493 yuan compared with the year 1998.The successful measures and experiences of Yan-gou watershed are worth promoting on the Loess Plateau.
Appraisal of typical rural development models during rapid urbanization in the eastern coastal region of China

The sustainability of regional rural development depends on the integrated status and the coordination between rural resources-environment conditions and rural socioeco-nomic development. In this paper a diagnostic indicator system is proposed to appraise four representative rural development models such as Mentougou model, Taicang model, Yueqing model and Qionghai model in the eastern coastal region of China from the integrated per-spective of population, resources, environment, and development. In conclusion, the forma-tion and evolution of these diverse rural development models are the direct response to the very different characteristics in the environment, market demand, and regional culture. These models are common in that their sustainability depends on the scientific guidance of the re-gional development functional positioning, strong intra-regional interactions, and self-adaptability to the external conditions.
