生态环境新闻发布：从权威发布、回应关切到价值传播

生态环境宣传是生态文明建设的重要组成部分。近年来,生态环境部通过新闻发布这一对外传播方式,对生态环境宣传工作进行了一系列探索和实践。“十四五”时期,生态环境新闻发布工作将从持续唱响主旋律、坚持围绕中心、积极回应热点、讲好中国生态环保故事等方面继续发力,为生态文明建设营造良好的舆论氛围。

我国首份省级生态文明建设评价报告发布

我国首份综合性省级生态文明建设评价报告9月25日在京发布。报告显示：北京、上海、海南、天津、浙江、福建等省份的生态文明建设排名靠前，其中北京连续三年名列榜首。课题研究组组长、北京林业大学生态文化研究中心主任严耕教授介绍，报告以国家相关部门发布的权威数据为基础，依据22项具体指标，对2005年至2007年各省份（不含港澳台）的生态文明建设情况进行了综合评价。     

我国生态文明制度建设与创新

保护生态环境、加强生态文明建设必须依靠制度保障。党的十八大报告提出,要大力推进生态文明建设,并将加强生态文明制度建设作为当前和今后一个时期要重点抓好的四个方面工作之一。强调建立体现生态文明要求的目标体系、考核办法、奖惩机制,建立健全生态环境相关制度,加强生态文明宣传教育,增强全民节约意识、环保意识、生态意识。同时,党的十八届三中全会进一步强调生态文明制度的建设,提出建设生态文明,必须建立系统完整的生态文明制度体制,用制度保护生态环境。这就意味着生态文明建设将从侧重理论、理念建设发展到加强制度建设的新阶段。     

以生态环境监测推动新时代生态文明建设

生态环境监测在生态环境工作中具有基础性地位,以生态环境监测推动生态文明建设具有重要意义。本文从中共十九大关于生态文明建设的阐述入手,指出应全面理解和领会党中央对生态环境的决策部署,提出深入理解新时代生态文明建设与生态环境监测的关系、以中央生态环境监测决策部署为指引开展生态环境监测、以全面从严治党确保生态环境监测数据"真、准、全"的生态环境监测工作思路。

Attempts to train goldfish to respond to magnetic field stimuli

Two different conditioning procedures, one appetitive and the other aversive, were used in separate attempts to demonstrate response to magnetic fields in the goldfish, Carassius auratus. Our results lead us to question those of an orientation experiment by Becker, although we recognize the possibility that goldfish may be sensitive primarily to magnetic field direction rather than intensity and that their directional sensitivity may be evidenced most readily by orientation in the field.

Croppers to livestock keepers: livelihood transitions to 2050 in Africa due to climate change

The impacts of climate change are expected to be generally detrimental for agriculture in many parts of Africa. Overall, warming and drying may reduce crop yields by 10–20% to 2050, but there are places where losses are likely to be much more severe. Increasing frequencies of heat stress, drought and flooding events will result in yet further deleterious effects on crop and livestock productivity. There will be places in the coming decades where the livelihood strategies of rural people may need to change, to preserve food security and provide income-generating options. These are likely to include areas of Africa that are already marginal for crop production; as these become increasingly marginal, then livestock may provide an alternative to cropping. We carried out some analysis to identify areas in sub-Saharan Africa where such transitions might occur. For the currently cropped areas (which already include the highland areas where cropping intensity may increase in the future), we estimated probabilities of failed seasons for current climate conditions, and compared these with estimates obtained for future climate conditions in 2050, using downscaled climate model output for a higher and a lower greenhouse-gas emission scenario. Transition zones can be identified where the increased probabilities of failed seasons may induce shifts from cropping to increased dependence on livestock. These zones are characterised in terms of existing agricultural system, current livestock densities, and levels of poverty. The analysis provides further evidence that climate change impacts in the marginal cropping lands may be severe, where poverty rates are already high. Results also suggest that those likely to be more affected are already more poor, on average. We discuss the implications of these results in a research-for-development targeting context that is likely to see the poor disproportionately and negatively affected by climate change.     

Soil microbial response to herbicides applied to glyphosate-resistant canola

Adoption of glyphosate-resistant canola (Brassica napus L.) has increased glyphosate applications to this crop, and concerns have been raised about unintended consequences of these multiple applications. A field trial was conducted to evaluate the effects of pre-seed and in-crop glyphosate and alternative herbicides on soil microbial community functional structure, diversity and biomass. Pre-seed treatments were 2,4-D, glyphosate and 2,4-D + glyphosate, and in-crop treatments were glyphosate applied once, glyphosate applied twice, ethalfluralin, ethalfluralin + sethoxydim + ethametsulfuron + clopyralid, and sethoxydim + ethametsulfuron. Rhizosphere and bulk soil was collected at flowering stage of canola and analyzed for bacterial community-level substrate utilization patterns and microbial biomass C (MBC). Where differences were significant, pre-seed application of both 2,4-D and glyphosate altered the functional structure and reduced the functional diversity of soil bacteria, but increased MBC. These effects were not necessarily concurrent. The reduction in functional diversity was due to reduction in evenness, which means that the soil where both pre-seed herbicides had been applied was dominated by only few functional groups. In 1 year, two in-crop applications of glyphosate also reduced the functional diversity of soil bacteria when applied after pre-seed 2,4-D, as did in-crop sethoxydim + ethametsulfuron following pre-seed glyphosate. Even though significant differences between herbicides were fewer than non-significant differences, i.e., there were no changes in soil microbial community structure, diversity or biomass in response to glyphosate or alternative herbicides applied to glyphosate-resistant canola in most cases, the observed changes in soil microbial communities could affect soil food webs and biological processes.
