The development of biomonitoring programs based on the macroinvertebrate community requires the understanding of species distribution patterns, as well as of the responses of the community to anthropogenic stressors. In this study, 49 metrics were tested as potential means of assessing the condition of 29 first- and second-order streams located in areas of differing types of land use in São Paulo State, Brazil. Of the sampled streams, 15 were in well-preserved regions in the Atlantic Forest, 5 were among sugarcane cultivations, 5 were in areas of pasture, and 4 were among eucalyptus plantations. The metrics were assessed against the following criteria: (1) predictable response to the impact of human activity; (2) highest taxonomic resolution, and (3) operational and theoretical simplicity. We found that 18 metrics were correlated with the environmental and spatial predictors used, and seven of these satisfied the selection criteria and are thus candidates for inclusion in a multimetric system to assess low-order streams in São Paulo State. These metrics are family richness; Ephemeroptera, Plecoptera and Trichoptera (EPT) richness; proportion of Megaloptera and Hirudinea; proportion of EPT; Shannon diversity index for genus; and adapted Biological Monitoring Work Party biotic index. 相似文献

Different organic ionic liquids (OILs) have been used as green solvents in Friedel–Crafts acylation and alcohol oxidation reactions. Specifically, three OILs were employed, 1-ethyl-3-methylimidazolium chloride, tetraethylammonium bromide, and 1-butyl-3-methylimidazolium chloride, and four reactions studied, acylation of toluene by acetyl chloride, acylation of benzene by propionyl chloride, oxidation of benzyl alcohol by N-methylmorpholine N-oxide, and oxidation of salicylic alcohol by o-iodoxybenzoic acid. The reactions were carried out, at room temperature, in a well-stirred lab-scale glass batch reactor, under inert atmosphere and for reaction times ranging from 5 to 90 min. Gas chromatography was employed to characterize the reaction products. First of all, the desired products yield as a function of the reaction time was investigated. Moreover, simple kinetic models were built for the interpretation of the experimental results. Additional tests were carried out to assess the possibility of recycling the OILs employed. The results of this preliminary study were satisfactory as the OILs investigated proved to be good media in which to carry out the reactions studied in this work (desired products yield greater than 90% were achieved). Moreover, the reaction rate expressions of the kinetic models were able to satisfactorily predict the experimental results. Finally, the possibility of recycling the OIL (in one of the reactions) was proved to be feasible and this suggests the use of recycled OIL together with a fresh make-up, to match high yield values with economical/ecological advantages. 相似文献

Economic theory provides different perspectives on the relationship between environmental regulation and company environmental and competitive performance. A frequently analysed issue refers to the impact of environmental regulation on company performance. Using qualitative data collected within the recently completed Environmental regulation and Market forces Providing Incentives for Resource Efficiency (EMPIRE) project, we analysed the relationship between environmental regulation and company competitiveness, operating in the building and construction (B&C) sector. Empirical evidence from the correlation analysis emphasises that environmental regulation can be an important driver of competitive performance improvements in relevant segments of the European B&C sector. 相似文献

Asymmetry in traits of sexual relevance may impair copulation behaviour and sexual performance of males, ultimately resulting
in a fitness cost. Freshwater crayfish males use chelae, a sexually selected trait, to secure and position the female prior
to and during mating. Thus, a relatively large chelae asymmetry, resulting from accidental loss and regeneration of one cheliped
after autotomy, could have great consequences for male sexual behaviour. We studied copulatory behaviour and sperm expenditure
of males paired to a mated female in Austropotamobius italicus, a freshwater crayfish species where both male and female mate multiply and where last-mating males are able to actively
remove previously deposited sperm. We aimed at assessing whether male sperm removal and expenditure varied according to sperm
allocated by first-mating males, and according to copulation behaviour and phenotypic traits (carapace length, chelae length
and relative chelae asymmetry) of second-mating males. Second-mating males did not adjust their ejaculate size in relation
to first-mating male ejaculate, nor to the first-mating male’s sperm removed. Moreover, the amount of sperm removed by second-mating
males increased with increasing first-mating males ejaculate size, and first-mating male sperm remaining after removal did
not correlate with the original first-mating male ejaculate size. Interestingly, the amount of sperm removed by second-mating
males decreased with increasing relative chelae asymmetry, while increasing with male body size. However, second-mating (but
not first-mating) asymmetric-clawed males produced larger ejaculates than symmetric-clawed ones. Importantly, the proportion
of second-mating male sperm remaining after the two matings did not vary with relative chelae asymmetry nor with body size
of second-mating males. Thus, small, asymmetric-clawed crayfish males appear to adopt sperm allocation tactics that allow
them to fully compensate for their inferior sperm removal ability. 相似文献
