Alteration of the spatial variability of natural flow regimes has been less studied than that of the temporal variability, despite its ecological importance for river ecosystems. Here, we aimed to quantify the spatial patterns of flow regime alterations along a river network in the Sagami River, Japan, by estimating river discharge under natural and altered flow conditions. We used a distribute...

Abstract Concentration-discharge relationships in water chemical time series can provide important insights into sources, mobilization, and delivery of solutes particulates stream networks. The observed are often complex, including nonlinear hysteretic patterns reflecting seasonal, climatic, land management changes biogeochemical release hydrological transport to streams. Using standard single ...

BACKGROUND Although antipsychotic polytherapy is considered appropriate in limited circumstances (e.g., during a brief "cross-titration" period when switching medications), its increasing prevalence indicates use beyond this limited scope. Despite absence of support in the medical literature and higher costs, antipsychotic polytherapy is common in the treatment of schizophrenia and related diso...

Effective nutrient pollution mitigation measures require in-depth understanding of spatio-temporal controls on water quality which can be obtained by analyzing export regime and hysteresis patterns in concentration-discharge () relationships. Such analyses high-frequency data (hourly or higher resolution), hampering the assessment widely available low-frequency (monthly, biweekly) regulatory da...

Many of us have been watching the Olympics this week (how about that Phelps?). The first week culminated with an exciting individual women’s gymnastics competition. Despite the home advantage (see Balmer and Nevill, 2003 in the annotated bibliography), Americans Nastia Liukin and Shawn Johnson took Gold and Silver respectively (63.325 and 62.725), with Chinese Yilin Yang winning Bronze (62.650)...
