“…The consistent, positive responses and the absence of undesirable outcomes lead us to recommend nutrient addition as a valuable restoration technique to enhance primary production in the Kootenai River and potentially in other anthropogenically oligotrophic rivers and streams, with the caveat that ecosystems respond to nutrient additions in highly specific ways (Artigas et al 2013). Nutrient addition, coupled with other management tools, such as habitat restoration and foodweb analysis (Naiman et al 2012), collectively can help restore threatened fish populations.…”

“…After the translocation, the variability in ETS activity and O 2 consumption in the biofilm increased, which could be linked to the stress of the translocation process, rather than a natural variation in the communities. In long term experiments, metabolic variables have shown to stabilize (Sabater et al 2011), linking streams exposed to urban impacts to a higher heterotrophic activity in the sediment (Bukaveckas et al 2002, Artigas et al 2013, Aristi et al 2015. However, respiration endpoints from the sediment should be analyzed with caution for short-term translocation experiments aimed to recognize fast changes in water quality conditions.…”

Stream biofi lms are among the fi rst to react to environmental degradation, since their structural and functional characteristics are tightly linked to the physicochemical variables in the water and sediment. The objectives of this research were to study the differences in chlorophyll-a, bacterial density and metabolism endpoints of epipelic biofi lms in nutrient-rich streams under different physical-chemical conditions in the stream water in relation to changes in urbanization, and to measure the short-term responses (up to 72 h) in the biofi lm when translocated to more urbanized sites. For these purposes, chlorophyll-a, bacterial density, biofi lm respiration (electron transfer activity) and O 2 consumption were measured in epipelic biofi lms in nutrient-rich streams exposed to different levels of urbanization after a 30 day colonization. Afterward, biofi lms were translocated downstream to more polluted sites, and sampled to identify any fast occurring changes to be considered as potential indicators of environmental degradation. Results show that in the nutrient-rich streams studied, the structural characteristics of the biofi lm were linked to urbanization, and even after a short time following the translocation, chlorophyll-a and bacterial density varied, refl ecting the environmental degradation. On the other hand, metabolic variables were highly variable and produced inconsistent results when representing an increase in urbanization.
