The Yellow River of China runs mainly through an arid and semiarid midlatitude region that has experienced
substantial anthropogenic and climatic change. This area includes the carbonate-rich Loess P...
Hydrologic control of nitrogen removal, storage, and export in a mountainstream
Hydrologic control nitrogen removal storage mountains tream
font style='font-size:12px;'>
2014/4/17
Nutrient cycling and export in streams and rivers should vary with flow regime, yet most studies of stream nutrient transformation do not include hydrologic variability. We used astable isotope tracer...
Hydrologic and biotic influences on nitrate removal in a subtropical spring-fed river
Hydrologic biotic influences on nitrate removal a subtropical spring-fed river

2014/4/16
We use a long-term chemical and hydrologic record in combination with longitudinal sampling and highfrequency nitrate (NO{3) measurements from in situ sensors to describe temporal and spatial patterns...
Analyzing the safety of removal sequences for piles of an offshore jacket platform
jacket platform removal safety analysis stress
font style='font-size:12px;'>
2011/9/13
An inevitable consequence of the development of the offshore petroleum industry is the eventual obsolescence of large offshore structures. Proper methods for removal of decommissioned offshore platfor...
An assessment of nitrogen removal from headwater streams in an agricultural watershed, northeast Ohio, U.S.A.
An assessment of nitrogen removal headwater streams agricultural watershed northeast Ohio U.S.A.
font style='font-size:12px;'>
2014/4/21
The objective of this project was to assess in-stream nitrogen removal capacity in a fragmented agricultural landscape and to compare removal capacities in streams with agricultural or residential (he...
Assimilatory uptake rather than nitrification and denitrification determines nitrogen removal patterns in streams of varying land use
Assimilatory uptake nitrification denitrification deter nitrogen removal patterns in streams of varying land use
font style='font-size:12px;'>
2014/4/18
Agricultural and urban land use increase nitrogen (N) concentrations in streams, which can saturate biotic demand by plants, algae, and bacteria via assimilative uptake, and by nitrification and denit...

Sponges and ascidians control removal of particulate organic nitrogen from coral reef water
Sponges and ascidians control removal particulate organic nitrogen coral reef water
font style='font-size:12px;'>
2014/5/13
We studied removal rates of plankton and total particulate organic nitrogen (PON) by benthic reef communities from the overlying water in a large experimental flume. The flume was filled with mixtures...
Sediment and nutrient dynamics following a low-head dam removal at Murphy Creek, California
Sediment nutrient dynamics
font style='font-size:12px;'>
2014/5/13
We studied the impact of the removal of a 3-m dam on sediment and nutrient export. In the year after dam
removal, sediment and nitrogen (N) export increased by an order of magnitude over the previous...
Zooplankton recovery after fish removal: Limitations of the egg bank
Zooplankton recovery bank
font style='font-size:12px;'>
2014/5/16
The Allee effect, operating via mate limitation, theoretically reduces the probability of recovery from local
extinction of dioecious zooplankton relative to species that can reproduce asexually. We ...
Observations of particle capture on a cylindrical collector: Implications for particle accumulation and removal in aquatic systems
Observations aquatic systems
font style='font-size:12px;'>
2014/5/14
Capture of suspended particles by cylindrical collectors is an important mechanism in many aquatic processes,
such as larval settlement, suspension feeding, and vegetative filtration. In these ...
In situ feeding and element removal in the symbiont-bearing sponge Theonella swinhoei: Bulk DOC is the major source for carbon
In situ feeding element remova
font style='font-size:12px;'>
2014/5/20
The vast majority of organic matter in the world ocean is found in the dissolved pool. However, no evidence has
been demonstrated for direct uptake of bulk dissolved organic matter (DOM) by organisms...
