Apple snails are large freshwater snails belonging to the family Ampullariidae that inhabit
tropical to temperate areas. The South American apple snails Pomacea canaliculata and …

Despite their socio-economic and ecological importance, rivers are among the most
threatened ecosystems. As a result, reliable and affordable monitoring system is …

We analyzed the diatom assemblages inhabiting the epipelic biofilm of a Pampean stream,
characterized by their high basal nutrient levels, when exposed to a continuous surplus of …

Benthic diatoms are often used for assessing environmental conditions, such as water
quality and habitat conditions in stream and river systems. Although laboratory experiments …

Trophic flexibility is a relevant trait in the potential for organisms to establish widely, maintain
high abundances and spread after invasion. Pomacea canaliculata is an apple snail that …

One of the most important effects derived from the intensive land use is the increase of
nutrient concentration in the aquatic systems due to superficial drainage. Besides, the …

The theory of ecological stoichiometry holds that heterotrophs are mostly homeostatic and
exhibit less variation in body stoichiometry than do autotrophs. Most studies of stream …

Aquatic macrophytes supply an important link in freshwater systems through their multiple
functions and ecosystem services. However, invasive generalist herbivores threatened their …

The feeding habits of Chironomidae in hill streams in the pampean region have not been
described. In this study, we analyzed the gut contents of this insect family with an aim at …

Macrophytes were transplanted into a lowland stream affected by river engineering works.
The aim was to analyse the feasibility of their reintroduction and potential to be used for the …
