This study assesses the effects of vegetation natural tree and shrub regeneration in semi-arid forests patterns and environmental factors on the abundance of of the Zagros mountains, western Iran. We sampled 120 releves at different topographic positions in a protected area of the studied region. Floristic composition, slope, elevation and soil properties were recorded at each releve, and woody seedling density was measured. We have first discerned five floristic groups using two-way indicator species analysis （TWINSPAN）, detrended correspondence analysis （DCA）, and canonical correspondence analysis （CCA） and then explored the relationships among the floristic group compositions, environmental factors and seedling densities. The indicator species of the five groups were Quercus brangi, Acer monspessulanum, Cerasus microcarpa, Rhamnus arvensis and Astragalus licyoides. Our results indicated that these groups were significantly affected by elevation and soil properties and the soil properties refer to： EC （electrical conductivity）, N （nitrogen）, K （potassium）, Om （organic matter）, and bulk density. Woody regeneration was composed of Q. brangi, A. monqJessulanum, C microcarpa, Amygdalus scopada and Crataeguspongca seedlings. The highest density of seedlings was found for Q. brantii （97.14 （_＋48.00） plants/hm2） and the lowest for A. scoparia （2.28 （＋1.50） plants/hm2）. Quercus brantii was the dominant species and the seedling density was positively correlated with soil pH and P （phosphorus） values. Amygdalus scoparia regeneration was negatively correlated with elevation, and the seedling density peaked in C. microcarpa group. There was no significant variation in distribution of C. pongca seedlings among the groups, but the seedling density of this species was positively correlated with slope and K. Cerasus microcarpa seedlings were more abundant in the Q. brantii group than in other groups. This study showed that the regeneration of tree and shrub species was unequally

On the effectiveness of dry drainage in soil salinity control

引用

Science China(Technological Sciences) 2009年第11期52卷 3328-3334页

作者： VINCENT bernard BOUARFA Sami VIDAL Alain Cemagref BP 44 92163 Antony Cedex France Cemagref 361 rue Jean-Franois Breton BP 5095 34196 Montpellier Cedex 5 France

Dry drainage is thought to be a potential approach to control soil salinity. This study took the Hetao Irrigation District as an example and evaluated the effectiveness of dry drainage by using remote sensing, a conceptual model and a field experiment. Archived remote sensing images from 1973―2006 were used to delineate the temporal and spatial change of soil salinity. The conceptual water and salt balance model was used to evaluate the role of dry drainage in removing excess salt from the irrigated land. The field experiment was performed to get field validation and give more accurate estimation. The results show that dry drainage did contribute to remove excess salt from the irrigated land and succeed in controlling soil salinity in the Hetao Irrigation District. It can be taken as an alternative approach in (semi-)arid area where artificial drainage is not applicable.

Palaeogeography of a shallow carbonate platform:The case of the middle to Late Oxfordian in the Swiss Jura mountains

Journal of Palaeogeography 2015年第3期4卷 251-268页

The Oxfordian （Late Jurassic） carbonate-dominated ptatform outcropping in the Swiss Jura mountains offers a good biostratigraphic, sequence-stratigraphic, and cyclostratigraphic framework to reconstruct changes in facies distribution at a time-resolution of 100 ka. It thus allows interpreting the dynamic evolution of this platform in much more detail than conventional palaeogeographic maps permit. As an example, a middle to Late Oxfordian time slice is presented, spanning an interval of about 1.6 ma. The study is based on 12 sections logged at cm-scale. The interpreted depositional environments include marginal-marine emerged ;ands, fresh-water lakes, tidal fiats, shallow lagoons, ooid shoals, and coral reefs. Although limestones dominate, marly intervals and dolomites occur sporadically. major facies shifts are related to m-scale sea-level changes linked to the orbital short eccentricity cycle （100 ka）. The 20-ka precession cycle caused minor facies changes but cannot always be resolved. Synsedimentary tectonics induced additional accommodation changes by creating shallow basins where days accumulated or highs on which shoals or islands formed. Autocyclic processes such as lateral migration of ooid and bioclastic shoals added to the sedimentary record. CEimate changes intervened to control terrestrial run-off and, consequently, siliciclastic and nutrient input. Coral reefs reacted to such input by becoming dominated by microbialites and eventually by being smothered. Concomitant occurrence of siliciclastics anddolomite in certain intervals further suggests that, at times, it was relatively arid in the study area but there was rainfall in more northern latitudes, eroding the Hercynian substrate. These examples from the Swiss Jura demonstrate the highly dynamic and （geologically speaking） rapid evolution of sedimentary systems, in which tectonically controlled basin morphology, orbitally induced climate and sea-level changes, currents, and the ecology of the carbon

Hierarchically Clustered Hmm for Protein Sequence motif Extraction with Variable Length

引用

Tsinghua Science and Technology 2014年第6期19卷 635-647页

作者： Cody Hudson bernard Chen Dongsheng Che Department of Computer Science University of Central Arkansas ConwayAR 72034 USA Department of Computer Science East Stroudsburg University East Stroudsburg PA 18301 USA

Protein sequence motifs extraction is an important field of bioinformatics since its relevance to the structural analysis. Two major problems are related to this field：（1） searching the motifs within the same protein family; and（2） assuming a window size for the motifs search. This work proposes the Hierarchically Clustered Hidden markov model（HC-Hmm） approach, which represents the behavior and structure of proteins in terms of a Hidden markov model chain and hierarchically clusters each chain by minimizing distance between two given chains＇ structure and behavior. It is well known that Hmm can be utilized for clustering, however, methods for clustering on Hidden markov models themselves are rarely studied. In this paper, we developed a hierarchical clustering based algorithm for Hmms to discover protein sequence motifs that transcend family boundaries with no assumption on the length of the motif. This paper carefully examines the effectiveness of this approach for motif extraction on 2593 proteins that share no more than 25% sequence identity. many interesting motifs are *** example motifs generated by the HC-Hmm approach are analyzed and visualized with their tertiary *** believe the proposed method provides a unique protein sequence motif extraction strategy. The related data mining fields using Hidden markova model may also benefit from this clustering on Hmm themselves approach.
