Paragraph(
'''The consequences of global change on rivers include altered flow regime, and entrance of
compounds that may be toxic to biota. When water is scarce, a reduced dilution capacity may
amplify the effects of chemical pollution. Therefore, studying the response of natural
communities to compromised water flow and to toxicants is critical for assessing how global
change may affect river ecosystems. This work aims to investigate how an episode of drought
might influence the response of river biofilms to pulses of triclosan (TCS). The objectives
were to assess the separate and combined effects of simulated drought (achieved through
drastic flow alteration) and of TCS exposure on biofilms growing in artificial channels.'''
),
Paragraph(
'''Thus, three-week-old biofilms were studied under four conditions: Control (normal water flow);
Simulated Drought (1 week reduced flow+2 days interrupted flow); TCS only (normal water flow
plus a 48-h pulse of TCS); and Simulated Drought+TCS. All channels were then left for 2 weeks
under steady flow conditions, and their responses and recovery were studied.
Several descriptors of biofilms were analyzed before and after each step. Flow reduction and
subsequent interruption were found to provoke an increase in extracellular phosphatase
activity, bacterial mortality and green algae biomass. The TCS pulses severely affected
biofilms: they drastically reduced photosynthetic efficiency, the viability of bacteria and
diatoms, and phosphate uptake. Latent consequences evidenced significant combined effects
caused by the two stressors.'''),
Paragraph(
'''The biofilms exposed only to TCS recovered far better than those
subjected to both altered flow and subsequent TCS exposure: the latter suffered more
persistent consequences, indicating that simulated drought amplified the toxicity of this
compound. This finding has implications for river ecosystems, as it suggests that the toxicity
of pollutants to biofilms may be exacerbated following a drought.'''
