The paper discusses how variability of river margins interacts with riparian function at the landscape level, in order to develop inferences about the future of this interaction with respect to potential effects of a global climatic change. A riparian approach to the ecology of river landscapes should be useful in that it offers an opportunity to improve our understanding and management of the effects of environmental change at the ecosystem level.

As emerging pollutants, bisphenol A (BPA), tetrabromobisphenol A (TBBPA) and its analogs have become widespread in the coastal environment of China. To investigate the occurrence of these novel contaminants in Chinese marginal sea, 176 seawater and 88 sediment samples were collected from the Yellow Sea and East China Sea. In seawater and sediment, the detection rates of TBBPA are 83.

This study investigates urban river policies, emphasizing the gaps in understanding the interactions between riverine communities and governance systems. Using empirical and theoretical methods, the research applies multivariate analysis and Structural Equation Modeling (SEM) to data from a representative sample of 1740 residents of Curitiba. The study maintains a 95% confidence level with a ±2.

Dredging in estuarine systems significantly impacts phytoplankton communities, with suspended particulate matter (SPM) and dissolved aluminum (Al) serving as indicators of disturbance intensity. This study assessed the effects of dredging in the São Marcos Estuarine Complex (SMEC), Brazil, over three distinct events (2015, 2017, 2020), involving varying sediment volumes and climatic influences. Prolonged dredging operations and increased sediment volumes led to a pronounced 43.

This study analyzes the implementation of the Indigenous Health Policy, focusing on the care practices of health teams of the Indigenous Health Care Subsystem in the Upper Solimões River in the Amazon region. Using ethnography as a methodological resource, the dynamics among participants, discourses, and power in the implementation of the policy are investigated, revealing a complex interconnection between practices and other contextual realities. Three phenomena emerge as critical influences on care practices: the medical-care model, the sanitation model, and the culture of performance.
