生态文学——生态文明背景下的新视点

生态文学是西方人文主义者通过对现代工业和科学技术的反思、质疑及对经济全球化过程中环境污染和人类生存状况的忧思而展开的课题。它在文艺学领域引起强烈的反响,生态文学、生态美学、生态批评观念相继提出,并迅速发展为一门显学。文章拟以人与自然协调发展的生态文明观为背景,阐释了生态文学的概念,探讨了生态文学作品的社会价值。

XXXII.—Nouveaux Bruchidæ

The bush cricket Psorodonotus illyricus is indigenous to the Balkans. Singing males of this species are highly mobile. The acoustic factors which might influence the locomotion were investigated in the field. The mobility of the males results in an often random distribution pattern. Interactions between the males are purely acoustic, and the duets are characterized by periods of good and poor alternation. Playback experiments, field observations and tape recordings of duetting males indicate that singing rate and sound intensity affect alternation behaviour and locomotion. However, the effect of the two song parameters is related to the time of the day, a phenomenon which might be due to (a) changes in the sound field around a singing male, and (b) altering microclimatic factors during the activity period of the insects.

On the polymorphism of cyanogenesis in Lotus corniculatus L.

Most populations of the legume Lotus corniculatus are polymorphic for the characters of leaf cyanogenesis and petal cyanogenesis. The distribution of these phenotypes was investigated in a section of chalk quarry where the vegetation ranged from pioneer species growing on almost bare chalk through to a mature grassland assemblage. The vegetation surrounding randomly chosen L. corniculatus individuals was recorded and this information was used to compare the environments in which the different phenotypes were growing. Leaf cyanogenic plants were found to occur at higher frequencies in grassland areas than in the more open conditions typical of earlier stages in the succession at the quarry. Factors that may be responsible for the distribution of the phenotypes are discussed.     

化学平衡与生态平衡

<正>化学平衡与生态平衡存在着一定的内在联系,它们具有相类似的动态特征。化学平衡原理对研究化学变化进行的方向和限度,实现有利于人类的物质和能量转化,具有普遍的指导意义。应用吕·查德里原理可以很好地解释生态平衡的移动规律。模拟化学平衡常数表达式可以建立生态平衡常数的定量概念,并由此产生对生态平衡更科学的理解。
