“…These results demonstrate high sensitivity of this approach. In the study of El Haj et al [17], 24, 240, 2400 and 24,000 µg⋅L -1 of Gl (in the composition of Roundup Transorb® formulated product) revealing the ex vivo cytotoxicity at the exposures to 24 and 2,400 µg⋅L -1 of Gl in the tissues of the bivalves. Despite Gl is one of the most used herbicide worldwide, its biological effects are poorly investigated [18].…”

“…The samples of digestive gland and gills were maintained at temperature -40 °C till exposure (no more than a week). The modified ex vivo approach of El Haj et al [17] was used. Selection of Gl concentration in the present study was based on environmentally relevant concentrations of this herbicide.…”

“…Selection of Gl concentration in the present study was based on environmentally relevant concentrations of this herbicide. For example, according to environmental qua lity standards of Brazilia, the maximum value allowed for Class I waters for glyphosate is 65 µg/L [17]. Environmentally realistic concentrations of Gl in Europe corresponding to dozens and hundreds of µg⋅L -1 [7].…”

“…We treated isolated tissues of U. tumidus mussels with organophosphonate pesticide glyphosate (Gl, formulation Roundup MAX, Monsanto, USA) at concentrations 34, 68, 169 and 338 µg⋅L -1 (corresponding to 13.3, 26.7, 66.8 and 133.6 µg⋅L -1 of Gl) during 2 h at 20 o C followed by 15 h at around 2 °C. Basing on pilot exposures and skepticism concerning quality of samples after long time in warm conditions, we reduced the time of exposure at 20 °C compare to conditions proposed by El Haj et al [17] (15 h). For each exposure, pairs of samples were taken from six mollusks.…”

“…Index of cell vitality as lysosomal membrane stability was detected from the Neutral Red Retention (NRR) test, as it was described by El Haj et al [17]. Briefly, tissues were incubated with neutral red for 2 h to allow for uptake of supravital dye into the lysosomes of viable cells.…”

dingly to a decrease of the MT and/or GSH concentrations. However, the levels of TBARS and PC were not changed comparing to control detecting the early stage of the injury. Surprisingly, NRR increased in the exposures to higher concentrations of glyphosate, probably due to strong chelating ability of glyphosate or other compounds of formulation. This study allows us to detect the earlier biological effects of glyphosate in the low environmentally realistic concentrations. Further validation of this approach needs the comparison of the results in the ex vivo and in vivo experiments.

The ecosystem services approach to conservation is becoming central to environmental policy decision making. While many negative biological invasion-driven impacts on ecosystem structure and functioning have been identified, much less was done to evaluate their ecosystem services. In this paper, we focus on the often-overlooked ecosystem services provided by three notable exotic ecosystem engineering bivalves, the zebra mussel, the quagga mussel, and the golden mussel. One of the most significant benefits of invasive bivalves is water filtration, which results in water purification and changes rates of nutrient cycling, thus mitigating the effects of eutrophication. Mussels are widely used as sentinel organisms for the assessment and biomonitoring of contaminants and pathogens and are consumed by many fishes and birds. Benefits of invasive bivalves are particularly relevant in human-modified ecosystems. We summarize the multiple ecosystem services provided by invasive bivalves and recommend including the economically quantifiable services in the assessments of their economic impacts. We also highlight important ecosystem disservices by exotic bivalves, identify data limitations, and future research directions. This assessment should not be interpreted as a rejection of the fact that invasive mussels have negative impacts, but as an attempt to provide additional information for scientists, managers, and policymakers.
