Modern science is global. This is particularly true of environmental science, which has been guided to a considerable extent by international environmental policy. Accordingly, one might expect the standards of scientific research around the globe to have unified over the last 30 years. Yet environmental scientists from different nations and scientific schools have demonstrably dissimilar views on key environmental issues. This is the conclusion we reached after a series of in-depth interviews with prominent American and Russian environmental scientists. The greatest difference was found in the perception of two global issues—stratospheric ozone depletion and climate change. 相似文献

The present study attempted to evaluate the carcinogenicity of natural phenolic compounds with previously demonstrated antifungal activity, using a computational structure–cytotoxicity approach, namely the quantum structure cytotoxicity relationship model. The cytotoxicity of 15 phenolic compounds with antiviral activity 96?h after treatment was studied using the AdmetSAR computational program. Per the EPA classification, four of the investigated compounds would be included in the second cytotoxicity category, four in the third category, and six showed no toxicity, rendering the studied natural phenolic compounds much less toxic to aquatic life than synthetic pesticides, the organophosphorus compounds, which mostly fall into the first and second categories of toxicity. 相似文献

Concentrations of Fe, Mn, Zn, Pb, Cu and Cd in soil solutions taken in the vicinity of a sulphur mine range from 354 to 9080
μM L−1, and exceeded the concentrations measured in solutions from light acid arable soils. The content of each metal was a negative
function of either the solution pH or of Ca concentration.
Reclamation of S-contaminated soil by an application of 2000 tonnes of limestone per hectare did not significantly affect
the solubility of trace metals, whereas equilibration of soil samples with CaCO3 in the laboratory decreased solubility of metals, especially in the soil under moist conditions.
Sulphur deposition may modify the natural cycling of metals in soils. 相似文献

Despite their potential importance in structuring reef communities, invertebrate corallivores and their population structures are poorly understood. We found distinct differences in the population structures (length-frequency distribution and sex ratio) of the corallivorous gastropod Coralliophila abbreviata residing on two coral-host taxa, Montastraea spp. and Acropora palmata, in the Florida Keys. In each of two survey years, around 50% of the Montastraea spp. colonies were infested, with a mean snail density of eight snails per infested colony (range 1–45), while around 20% of A. palmata colonies harbored three snails per infested colony (range 1–23). Variation in patterns of snail occurrence was also observed within a host taxon. A. palmata occurred in low- and high-density stands (0.4 and 1 colony m–2, respectively, at the initial survey) at different sites. Hurricane Georges struck the area in September 1998. When resurveyed in 1999, density of colonies in low-density stands had decreased by 75% to 0.1 colonies m–2. This decrease was accompanied by a doubling in the proportion of colonies infested with snails (from 19% to 46%) and an increase in snail density per infested colony (from 3.7±3.3 SD to 5.4±4.6 SD) as snails apparently concentrated on surviving A. palmata. In contrast, sites with high density A. palmata stands (thickets) retained colony densities of about ~1 colony m–2 among years, while snail infestation increased only from 9% to 14% of colonies surveyed and snail density essentially remained unchanged (from 2.7±1.8 to 2.9±1.9 snails per infested colony). Snails collected from Montastraea spp. were shorter than those from A. palmata in low-density stands and were longest on A. palmata in thickets. On both host taxa, female snails were longer than males. The sex ratio of snails on Montastraea spp. hosts was even (1:1), while that of snails on A. palmata was skewed (70% males). Factors that could explain observed differences in size structure and sex ratio between Coralliophila populations on the two coral host taxa include: differential susceptibility to predators, influence of host tissue nutritional quality and/or secondary metabolite content, and genetic differences (cryptic species). The host-specific characteristics of C. abbreviata populations imply that the impact of gastropods on reef communities will vary with the coral species composition. 相似文献
