“…Thus, at relatively high concentrations of toxicants in water Shardara reservoir, their essential impact on the zooplankton has not been identified. This may be due to its trophic status (Serra et al, 2010), favorable feed supply (Sarma et al, 2000), complex nature of contamination that includes the detergent components (Sobrino-Figueroa, 2016) represented in the Shardara reservoir by organic polyphosphates.…”

“…The sensitivity of planktonic invertebrates towards heavy metals and pesticides depends on the physic-chemical conditions (Garcı´a-Garcı´ et al, 2006), the trophic status of the reservoir (Serra et al, 2010), the presence of detergent components (Sobrino-Figueroa, 2016), as well as on relat ion to the species (Wang et al, 2009;Sakamoto et al, 2010), their neonatal size (Vesela & Vijverberg, 2007), the number of single-celled algae (Sarma et al, 2000) which have mechanis ms for heavy metals detoxification (Macfie & Welbourn, 2000).…”

The Shardara reservoir is located in southernmost Kazakhstan, in the zone of intensive farming and industrial development. Zooplankton and basic parameters of the environment have been studied in the summer of 2015. Zooplankton was represented by 60 species. The average abundance of the community amounted to 92.9 thous. specimens m -3 , with biomass of 966.0 mg m -3 . Copepods and rotifers dominated. The Shannon index values were equal to 2.24 bit specimen -1 and 1.23 bit mg -1 . The average individual mass of a specimen reached 0.0082 mg. Nonparametric and multivariate analysis of the data showed that macrophytes, nitrates, total nitrogen, organic polyphosphates, and copper favorably influenced Rotifera. Possible reasons for a positive relationship between quantitative indicators of Cladocera and zinc content are discussed. The main negative factors for Copepoda were organic polyphosphates, nitrites, total nitrogen, cadmium, and lead. Decrease in the Shannon index values under the influence of cadmium, ammonium, HCCH isomers is associated with increased dominance of Acanthocyclops trajani in the contaminated areas. There was no significant impact of heavy metals and pesticides on most of the structural indicators of zooplankton which can be due to the complex nature of contamination of the reservoir.

“…However, the level of phototrophic biofilm community tolerance to toxicants depends not only on previous chronic exposure to the toxicant but also on other environmental parameters, such as phosphate content in the water ( , [Serra et al, 2010] and ) or light exposure history ( [Guasch and Sabater, 1998] and [Laviale et al, 2010] ). In our study, the between-channel difference in Cu tolerance cannot be explained by variation in physicochemical characteristics (PO4 concentrations, conductivity, light, etc.…”

The present study aimed at assessing the recovery of phototrophic and heterotrophic biofilm communities after a decrease in copper exposure. An original experiment was designed to evaluate the possible influence of non-exposed (i.e. pristine) communities (e.g. via immigration processes) in recovery dynamics. Laboratory channels were used to study the structural and functional changes in microbial communities after a 4-week Cu exposure period in the presence and absence of pristine biofilms. When pristine biofilms were present, phototrophic communities recovered within 6 weeks, both in terms of biomass, structure and photosynthetic activity. Recovery processes were also detected using the PICT approach. In contrast, in the absence of pristine communities, all of the Cu-induced changes recorded in the phototrophic communities remained throughout the recovery period.Regardless of the presence or absence of pristine biofilms, the decrease in Cu exposure did not abolish Cu-induced changes in bacterial community structure, whereas functional recovery (based on beta-glucosidase activity) was complete in both recovery contexts.These results revealed that microbial community response to a decrease in Cu exposure differs between phototrophic and heterotrophic communities. The presence of pristine communities greatly influences the structural and functional recovery of phototrophic communities, suggesting an important role of microbial immigration processes, but have far less influence on the recovery trajectory of heterotrophic communities. Highlights► We tested the influence of microbial immigration in biofilm recovery after a Cu exposure.► Recovery dynamics differed between phototrophic and heterotrophic communities.► Microbial immigration enhanced the recovery of phototrophic communities.► Heterotrophic community recovery slightly depended on microbial immigration processes.

“…Most studies have focused on the impact of toxicants (metals, pesticides, etc.) on the algal component of periphyton or phytoplankton using shortterm photosynthetic toxicity tests to bring to light tolerance induction (for instance Dorigo et al (2010) or Serra et al (2010)). Moreover, the toxicity tests are usually performed with the use of radioactive reagents, like incorporation of labelled-thymidine for bacterial growth and labelled-CO 2 for photosynthesis (see for instance Blanck 2002, Blanck et al 2003.…”

Low exposure levels of urban metals induce heterotrophic community tolerance: a microcosm validation

2011

The biological response of periphyton chronically exposed to metals of urban origin (Cd, Ni and Zn) was investigated with a Pollution-Induced Community Tolerance (PICT) approach using a previously developed short-term toxicity test based on β-glucosidase (heterotrophic) activity. Periphyton was grown on plastic membranes immersed in indoor aquaria contaminated with metals at realistic contamination levels (0.3, 3 μg/l for Cd, 5, 50 μg/l for Ni, 20, 200 μg/l for Zn). After 3 weeks of exposure, biofilms' parameters (dry-weight, chlorophyll a concentration, heterotrophic activity) were analyzed and tolerance acquisition of the heterotrophic communities was assessed using the toxicity test. Modifications of bacterial and eukaryotic community structure were assessed with Automated Ribosomal Intergenic Spacer Analysis (ARISA). Effects of metal exposure were observed on biofilms parameters in the Cd and Zn experiments. Tolerance levels increased for both Cd-exposed biofilms, and for the high metal treatment biofilms in the Ni and Zn experiments. Analysis of the ARISA profiles showed that metal exposure affected the structure of both bacterial and eukaryotic communities. Moreover, Cd tolerance of the Zn-exposed heterotrophic communities was evaluated, which showed that the Zn-tolerant community (high metal treatment in the Zn experiment) also became tolerant to Cd (co-tolerance). The study shows that tolerance acquisition can be detected after exposure to environmental metal concentrations using β-glucosidase activity as an endpoint in short-term toxicity tests.
