The toxicity of mononitrophenols and dinitrophenols (DNP) to luminescent bacteria Vibrio fischeri (Microtox test) and ciliated protozoan Spirostomum ambiguum (Spirotox test) was evaluated. Spirotox was more sensitive to the tested nitrophenols (NPs) than the Microtox test. 2,5-DNP was the most toxic and 2-NP was the least toxic to the both bioindicators. The toxicity depended greatly on the pH of the medium. The highest changes were observed for DNPs, where the toxicity decreased more than 20-times when the pH increased from 6 to 8. No significant decrease of the toxicity was found for NPs, when the pH increased from 6 to 7. Greater increase of the pH to 8 caused from 1.5 to 4-fold decrease of the toxicity. 相似文献

Large herbivores play key roles in terrestrial ecosystems. Continuous defaunation processes have produced cascade effects on plant community composition, vegetation structure, and even climate. Wood-pastures were created by traditional management practices that have maintained open structures and biodiversity for millennia. In Europe, despite the broad recognition of their biological importance, such landscapes are declining due to land-use changes. This calls for finding urgent solutions for wood-pasture conservation. To test whether introducing an ecological replacement of an extinct wild horse could have positive effects on wood-pasture restoration, we designed a 3-year rewilding experiment. Horses created a more open wood-pasture structure by browsing on seedlings and saplings, affected tree composition via selective browsing and controlled the colonization of woody vegetation in grassland-dominated areas. Thus, rewilding could be a potential avenue for wood-pasture restoration and biodiversity conservation. However, such benefits may not materialize without a necessary paradigm and political shift.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01320-0) contains supplementary material, which is available to authorized users. 相似文献
