Biofilm early stage development in two nutrient‐rich streams with different urban impacts
(John Wiley & Sons Ltd, 2018-09)
The aim of this study was to describe the colonization of the biofilm during its early stages under different concentrations of nutrients and organic matter, specifically in urban streams influenced by agriculture and ...
Fish-trematode systems as indicators of anthropogenic disturbance: Effects of urbanization on a small stream
(Elsevier Science, 2018-10)
Parasites have proven to display high responsiveness to anthropogenic stress, having, therefore a considerable value as bioindicators. We analysed the variability in the structure of parasite populations and assemblages ...
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 ...
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 ...
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 ...
Biocatalysed acidification and metal leaching processes in sediments of polluted urban streams
(Inderscience Enterprises, 2014-04)
Sediments of fluvial streams are a sink for pollutants such as heavy metals and organic recalcitrant compounds. In anoxic conditions, sulphide generation and alkalinisation cause precipitation of heavy metals. The redox ...
Effect of pollution on early diatom colonisation on artificial substrata in urban lowland streams
(Csiro Publishing, 2020-08-26)
The colonisation patterns of diatom assemblages were studied on artificial substrates in lowland streams with different urban pollution levels. Density, diversity, colonisation rates, ecological guilds and cell size classes ...
Where are the turtles when they are not? Underwater refuges used by Hydromedusa tectifera COPE, 1869 in a suburban stream
(Kluwer Academic Publishers, 2020-05-14)
Habitat requirements of Hydromedusa tectifera from an urban impacted stream from the Buenos Aires province, the Rodriguez stream, are here studied. We describe the type of underwater refuges, how they are used in different ...
