1 A multi-year study in the Sacramento-San Joaquin Delta system was carried out to exam2 ine the relationship between the survival of out-migrating Chinook salmon Oncorhynchus 3 tshawytscha and the amount of water exported from the system by the two major pumping 4 stations in the southern portion of the Delta. Paired releases of groups of coded-wire-tagged 5 juvenile late-fall run Chinook salm...

Analysis of one of the major surface oil spill consequences, which took place in 1994 on the territory of the Pechora River (Russia) catchment area, was carried out. Data on hydrocarbon products and their derivatives concentrations in muscle and liver tissues of several fish species living in the Pechora's Delta and the river tributaries were obtained. Comparative analysis of OCCs, PCBs and PAH...

Great changes in land use/land cover from rapid urbanization have occurred in the PearlRiver Delta, China. As the primary cause of land development in the urbanization process,urban expansion has mostly occurred on land with higher NPP, significantly impacting theregional ecosystems. The primary purpose of this study was to reveal the impacts of urbanexpansion on the regional NPP. The land cove...

This paper seeks to examine the relationship between education demand and entrepreneurs in the process of enhancing the growth of human capital in China. We develop a theoretical model that incorporates the important roles played by human capital, education and entrepreneurs. Then, we derive an immigration condition under which the demand for education depends on the existence of entrepreneurs....

Sedimentary material from coastal and nearshore areas in the Mississippi Delta region are comprised of different organic carbon sources with diverse ages that require isotopic and elemental records for resolving the various sources of plant residues. Carbon isotopic ((13)C, (14)C) values were used to differentiate contributions from plants using the C3, C4, and/or CAM (crassulacean acid metabol...

We examined the spatial distribution pattern and meteorological drivers of dengue fever (DF) in Guangdong Province, China. Annual incidence of DF was calculated for each county between 2005 and 2011 and the geographical distribution pattern of DF was examined using Moran's I statistic and excess risk maps. A time-stratified case-crossover study was used to investigate the short-term relationshi...

Introduction Sea level rise, especially combined with possible changes in storm surges and increased river discharge resulting from climate change, poses a major threat for a low-lying delta like the Netherlands. Future flood protection strategies need to take these possible changes into account. Therefore, high-impact, low-probability climate change scenarios for the Netherlands were developed...

Lake Matahina, an 8 km long hydroelectric storage reservoir, is a small (2.5 km), 50 m deep, warm monomictic, gorge-type lake whose internal circulation is controlled by the inflowing Rangitaiki River which drains a greywacke and acid volcanic catchment. Three major proximal to distal subenvironments are defined for the lake on the basis of surficial sediment character and dominant depositional...

in developing and newly industrialized countries, population growth and migration contribute immensely to the development of megacities and mega urban areas. in most cases, the rapid development ofcities has far-reaching consequences for the ecosystem in general and the hydrological cycle in particular. the developments in china within the last decades show an interesting, but complex setting. ...
