Environmental diagnosis of an urban basin from a social–ecological perspective
(Elsevier, 2019-08)
The critical factor in restoration and conservation of urban streams and their catchments is the human population, however the most of studies of urban ecosystems do not present social descriptors as concrete variables of ...
Specific indicator invertebrates of urbanized habitats in tributary streams of the Luján River basin (Buenos Aires, Argentina)
(EDP Sciences, 2021-06)
The increase of urbanized areas produces disturbances in rivers and streams, and its widespread effects reduce water quality and threaten aquatic biota. The aim of this study was to analyze changes in the invertebrate ...
Glyphosate and aminomethylphosphonic acid (AMPA) are commonly found in urban streams and wetlands of Melbourne, Australia
(Elsevier, 2020-01)
Glyphosate is the most widely-used pesticide for weed control in agriculture and in urban and residential areas. This is the first study to quantify glyphosate and AMPA levels in surface water in Australia from different ...
Micro and Macroscale Drivers of Nutrient Concentrations in Urban Streams in South, Central and North America
(Public Library of Science, 2016-09)
Global metrics of land cover and land use provide a fundamental basis to examine the spatial variability of human-induced impacts on freshwater ecosystems. However, microscale processes and site specific conditions related ...
Urbanisation reduces litter breakdown rates and affects benthic invertebrate structure in Pampean streams
(Wiley VCH Verlag, 2019-08)
The Pampean region has become one of the most urbanised areas in South America with more than 91% of the Argentinean population. This region is ideal for human settlements that have historically chosen riverine grassland ...
DETERMINATION OF FLOOD RISKS IN THE MORUMBI STREAM BASIN, PIRACICABA-SP
(Univ Estadual Paulista Julio Mesquita Filho, 2016-01-01)
In Brazil can be identified several environmental issues, one of the most recurrent are the floods. This phenomenon is concentrated in urban areas, in which the urbanization process has a key role being directly related ...
Fish assemblage structure in a Neotropical urbanised prairie stream exposed to multiple natural and anthropic factors
(Wiley Blackwell Publishing, Inc, 2021-07)
A myriad of factors affect stream fish assemblages, and most of them are intimately regulated by surrounding land uses. One of the most pernicious impacts on streams is the release of urban effluents. Accordingly, understanding ...
Temporal changes in the water quality of urban tropical streams: An approach to daily variation in seasonality
(2021-01-01)
Using water quality indices (WQIs) is one way to monitor watercourses for water quality. Currently, there is a lack of information about their behavior in the diurnal cycle because sampling is often carried out in the ...
