The nitrogen (N) cycle is one of the most important nutrient cycles in river systems, and it
plays an important role in maintaining biogeochemical balance and global climate stability …

Antibiotics are ubiquitously found in natural surface waters and cause great harm to aquatic
organisms. Stream biofilm is a complex and active community composed of algae, bacteria …

Agriculture impacts the ecological status of freshwaters through multiple pressures such as
diffuse pollution, water abstraction, and hydromorphological alteration, strongly impairing …

Using multimetric indices (MMIs) for monitoring the ecosystem health of rivers is common
practice. Increasing the applicability of MMIs needs understanding of the impacts of natural …

The European Water Framework Directive 2000/60/EC (WFD) has been implemented over
the past 20 years, using physicochemical, biological and hydromorphological elements to …

In most cases, intermittent rivers and ephemeral streams (IRES) form the principal surface
water bodies in Mediterranean regions and people are heavily dependent on them. Strong …

Anthropogenic activities are intensively affecting the structure and function of biological
communities in river ecosystems. The effects of anthropogenic pollution on single-trophic …

Climate change and pollution are two of the main environmental problems living organisms
currently face. Temperature can modify a toxicant's effects and the organism's response to it …

Urban pollution and hydrological stress are common stressors of stream ecosystems, but
their combined effects on ecosystem functioning are still unclear. We measured a set of …

Despite increasing interest in hydrological effects on riverine ecosystems, few studies have
documented the impact of hydrology on biofilm community functions, and those existing …
